Oʻahu is about 382,500-acres in size; the district of Puna on the island of Hawaiʻi is about 320,000-acres in size – almost same-same.
According to the 2020 census, Oʻahu has about 984,000-people and Puna has about 46,800. That means there are less than a half-acre per person on Oʻahu and about 7-acres per person in Puna.
For some, it sounds like optimal living; and, many are moving to the Big Island to enjoy this rural lifestyle.
Open spaces with room to roam, it sounds kind of like the Wild West. And, for some, that’s its nickname, however, not with the same context.
Wait, there’s more.
Between 1958 and 1973, more than 52,500-individual lots were created. There are at least over 40 Puna subdivisions. Geographically, these subdivisions are sometimes as big as cities.
For example, Hawaiian Paradise Park has over 8,800 building lots and is reportedly the second largest private subdivision in the United States. It is over 4-miles long and nearly 3½-miles wide.
Back then, they plotted out the subdivisions in cookie-cutter residential/agricultural lots across a grid, with very little space for other uses (such as parks, open space, government services, regional roads … the list goes on and on.)
To add insult to injury, most subdivision lots are accessed by private, unpaved roads. The streets generally lack sidewalks and lighting, and do not meet current County standards in terms of pavement width, vertical geometrics, drainage and other design parameters.
There are only two main roads to move the people in the district in and out – one (Route 130 – Keaau-Pahoa Road) goes into Pahoa to Kalapana; the other (Route 11 – Volcano Highway) serves the lots up in the Volcano area.
Most lots rely on individual catchment systems (captured off the roof and rainfall stored in water tanks) supplemented with private delivery trucks for drinking water. None of the subdivisions have central sewer systems. Large sections of some subdivisions are off the power grid.
Oh, and one more thing, about 6,400 subdivision lots lie in the highest lava hazard zone and over 500 of these are exposed to additional risks from subsidence, tsunami and earthquakes.
That’s not just hazards noted on a map; thousands of these lots have been covered by lava flows or have been rendered unbuildable by shoreline subsidence over the years.
While most of these subdivisions are on agricultural-zoned lands, the actual use of developed lots is predominantly residential.
At the time these subdivisions were approved, the Puna district was sparsely populated and, with the exception of a sugar plantation and a small-scale visitor attraction at the volcano, which had not yet been developed as a national park, there was little economic activity in the area.
Shortly after the approval of the first of these subdivisions, Hawai‘i was admitted as the 50th state. That event, coinciding with jet travel, spurred increased investment in the Islands.
To prevent the excesses of land speculation, Hawai‘i adopted the first State Land Use Law in the nation in 1961.
Most of the Puna district was placed in either the Conservation District or the Agriculture District when formal boundaries were established in 1964, and this somewhat served to abate the number of subdivision applications.
However, it wasn’t until the County adopted a subdivision ordinance in 1973, setting more rigorous lot size and infrastructure standards, that large subdivisions with minimal services were effectively discouraged.
In the first decade or so following the creation of the non-conforming subdivisions, lot sales were fairly brisk, but there was little lot development.
In the 1970 Census, the recorded population of the Puna District was only 5,154-residents, most of whom lived in the older settlements of Kea‘au, Pāhoa and Volcano.
That was then, over the years the population exploded, doubling to 11,751 in 1980, then up another 10,000 by 1990 (to 20,781,) and another 11,000 by 2000 (to 31,335,) and another 14,000 by 2010 (to 45,326) to the 2020 population of about 46,800.
Population growth has worn on the minimal infrastructure, as well as people’s patience.
Today, folks in Puna are living with the lack of planning and regulatory control over the subdivision bonanza days. But, they do benefit from lower sales prices (associated with the general lack of facilities and the huge availability.) Some say you are getting what you pay for.
This region is finally undergoing some short and long-range planning. And, there are attentive council members seeking to have Puna get its fair share.
Depending on your perspective, addressing the issues in this region today is either a planner’s nightmare or a planner’s dream. This is an area where I would love to get involved – for me, challenges create opportunities.
The image notes the individual parcels within the Puna district (overlaying the Google Earth image.) At this scale, many of the lots are not discernible – the fully gray areas indicate smaller lot residential uses, with no (or very limited) park space – where you can just see between the lines, these are 1-5 acre parcels.

Today, we typically reference King David Kalakaua as the ‘Merrie Monarch;’ and most also say it was his nickname used by those outside of Hawai‘i. Most suggest it was inspired by the king’s love of music, parties and fine food and drinks. Yet, it is not clear why we spell ‘Merry’ that way.
It is probably coincidental, but about the same time Kalakaua was ruling in the Islands, there were numerous articles written about King Charles II, who had been ruling about 200-years earlier in England. Charles was also referred to as the “Merry Monarch of England,” or simply, the “Merry Monarch.”
Charles II (born May 29, 1630, London—died February 6, 1685, London) was king of Great Britain and Ireland (1660–85). He was restored to the throne after years of exile during the Puritan Commonwealth.
The years of his reign are known in English history as the Restoration period. His political adaptability and his knowledge of men enabled him to steer his country through the convolutions of the struggle between Anglicans, Catholics, and Dissenters that marked much of his reign. (Britannica)
“Charles Stuart the 2nd of England who lived an “eventful life” with “wild orgies” in “his depraved and dissolute court” was referred to in England as the “merry monarch.” (It was sometimes spelled ‘merrie monarch.’)
He was described as “a man of great and varied talents, a heartless libertine, sunk in vice and debauchery, and soddened with lust”. (The Chelmsford Chronicle (Chelmsford Essex, England, January 13, 1860)
It is not clear if Charles II was referred to as the Merry Monarch during his reign; Hawai‘i’s King Kalakaua was also referred to as a Merry Monarch. However, the first reference of such appears to be in news accounts of his death. (He died January 20, 1891.)
Several, primarily Mid-Western, newspapers on the continent ran identical stories with the heading that stated “He Was a Merry Monarch” The lead line of the story was “King David of Hawaii is dead.” (January 29, 1891)
Later, the Honolulu Advertiser, in writing about the King in an October 23, 1901 article, noted, “when the merry monarch came to the throne a new nobility was created”.
In reference to Kalakaua, though, we call him ‘Merrie’, as noted above and below, it was not always so.
Early newspaper references to a Kalakaua nickname were all, effectively, using ‘Merry.’
In 1903, the Pacific Commercial Advertiser (PCA) referenced, “King Kalakaua, the merry monarch.” The next year, he was again referred to as ‘the merry monarch.’
Later, in 1904, the PCA reported on the christening of the infant son of Prince and Princess Kawananakoa where the paper stated, “the name of the ‘Merry Monarch of Hawaii’ was revived, for the young Prince will bear the name of David Kalakaua II.”
Later, the Honolulu Advertiser referred to Kalakaua as the “Merry Monarch of the Paradise of the Pacific.” Kuykendall’s 3rd and final volume, describing the “Kalakaua Dynasty,” says that it “covers the colorful reign of King Kalakaua, the Merry Monarch.”
Even the festival that bears the nickname is not clear, nor consistent, with the spelling …
The first hula festival (held in 1964) that bore Kalakaua’s nickname was called the ‘Merry Monarch Festival’. In anticipation of the event, the Hawaii Tribune Herald referred to “the first Merry Monarch Festival to be held in Hilo next April.”
Newspaper reports note that, “A purpose of the Merry Monarch Festival, a special project of the Hawaii Island Chamber of Commerce, is to develop an attraction that will draw visitors here during tourism’s slack period of the year.” (Hawaii Tribune Herald, March 31, 1964)
A later Hawaii Tribune Herald story (September 29, 1963) noted, “A Merry Monarch Festival designed to bring back for a brief period the colorful years if King Kalakaua will be held in Hilo next April, it was announced today by George Naope, promotor of activities for the County.”
In announcing that the Hawaii Island Chamber of Commerce had agreed to sponsor the “Merry Monarch Festival,” chairman Gene Wilhelm said, “the Merry Monarch Festival, named for Hawaii’s King Kalakaua, who reigned from 1874 to 1891, is planned for an annual event during the first week following Easter.” (Hawaii Tribune Herald, January 10, 1964)
in the early years, in addition to an annual parade and hula, there were a variety of other programs associated with the festival.
Men competed in a Kalakaua look-alike contest; quarter- and semi-finals of a sideburns-mustache contest at Mooheau Park. (If he was married, the festival gave a gift certificate to “The Most Understanding Wife” (Hawaii Tribune Herald)
A couple of athletic competitions also took place. Single riders and relay teams competed in the Merry Monarch Festival Bicycle Pete Beamer Derby and rode bicycles from the Kamehameha Statue in Kohala, headed through Waimea, along the Hamakua Coast and ended up at Kalakaua Park in Hilo. The winner of the 85-mile race received a trophy and $25.
Reminiscent of the old days of Hawai‘i when relays of the swiftest runners carried fresh fish to the chiefs, the festival had a 4-mile relay race through Hilo (starting and finishing at Mo‘oheau Park). The relay runners used mullet as ‘batons.’
Another of the early festival activities was a Treasure Hunt. Hunters were to dig up a buried box containing a Kalakaua medallion, redeemable for a cash prize, that was buried in a secret location.
“Samuel Clemens Moke, King Kalakaua’s emissary who pays daily visits to the Tribune Herald” provided cryptic clues on the treasure’s location. These were published in the Hawai‘i Tribune Herald.
In reporting on its 50th anniversary, The Hawaii Tribune Herald noted that, “Andres Baclig, the county bandmaster in 1964, composed a number called the ‘Merry Monarch Festival March.’”
“The song, which was received with much acclaim, was presented at the Mooheau Bandstand on April 2, 1964, and it was a spirited number, featuring ‘lots of trombones and baritones.’”
In a report on planning for the 5th annual festival in the Honolulu Advertiser (December 24, 1967), it was reported that, “The largest planning committee ever set up for a Hilo Merry Monarch Festival is at work on the fifth annual festival”.
The ‘Merry’ name was used at least until 1969.
However, the 1977 program for the festival was a bit ambidextrous. The program was titled ‘Merrie Monarch Festival,’ but text on its initial pages, noted, “Hilo’s Merry Monarch Festival is named for Kalakaua who was Hawaii’s Merry Monarch.”
In 1971, the first competitive Merrie Monarch contest took place at the Hilo Civic Auditorium. In 1979 the festival moved to the Edith Kanaka‘ole Tennis Stadium, where it has been held ever since.
In the late-1970s, newspaper reporting noted that performing at Hulihee Palace was the ‘Merry Monarchs Hawaiian Glee Club,’ “the foremost all male Hawaiian language singing group in the Islands (December 12, 1977). A similar concert to celebrate the birthday of “Hawaii’s Merry Monarch, Kalakaua” was held that year at the Waikiki Shell.
Today, the King and Festival are referred to as the ‘Merrie Monarch.’ It is not clear when and why the nickname or the festival name changed from ‘Merry’ to ‘Merrie’. However, the festival remains the premier hula competition.

Some suggest the overthrow of the Hawai‘i constitutional monarchy was neither unexpected nor sudden.
Dissatisfaction with the rule of Kalākaua and Lili‘uokalani initially led to the ‘Bayonet Constitution,’ then, the overthrow. “(M)ounting dissatisfaction with government policies and private acts of officials led to the formation of the Hawaiian League, a group of Honolulu businessmen.” (Forbes)
Challenges with Kalākaua
• Polynesian Confederacy
• “(Gibson) discerned but little difficulty in the way of organizing such a political union, over which Kalākaua would be the logical emperor, and the Premier of an almost boundless empire of Polynesian archipelagoes.” (Daggett; Pacific Commercial Advertiser, February 6, 1900)
Opium License Bribery Case
• Initially the king, through his minister of foreign affairs, disclaimed any involvement. However, “To cap the climax of the opium matter, the Attorney General proceeds to acknowledge that the money was paid over by the Chinese … (H)e informed the gentlemen interested in getting the money back that he would never accomplish his object so long as he allowed the newspaper to speak of the affair.” (Hawaiian Gazette, May 17, 1887)
Extravagance/Debt
• Although Kalākaua had been elected and serving as King since 1874, upon returning from a trip around the world (1881), it was determined that Hawaiʻi’s King should also be properly crowned.
• “ʻIolani Palace, the new building of that name, had been completed the previous year (1882), and a large pavilion had been erected immediately in front of it for the celebration of the coronation. This was exclusively for the accommodation of the royal family; but there was adjacent thereto a sort of amphitheatre, capable of holding ten thousand persons, intended for the occupation of the people.” (Liliʻuokalani)
Bayonet Constitution (1887)
• In 1887, the struggle for control of Hawaiʻi was at its height with David Kalākaua on the throne. But some of the businessmen were distrustful of him. “So the mercantile element, as embodied in the Chamber of Commerce, the sugar planters, and the proprietors of the ‘missionary’ stores, formed a distinct political party, called the ‘down-town’ party, whose purpose was to minimize or entirely subvert other interests, and especially the prerogatives of the crown, which, based upon ancient custom and the authority of the island chiefs, were the sole guaranty of our nationality.” (Liliʻuokalani)
Concern with Lili‘uokalani’s Attempt to Rewrite the Constitution
• “When Lili‘uokalani became Queen, she took the following oath: ‘I solemnly swear in the presence of Almighty God, to maintain the Constitution of the Kingdom whole and inviolate, and to govern in conformity therewith.’” (UH Law School)
• “On January 14, 1893, Lili‘uokalani was prepared to ignore the constitutionally mandated approval-by-two-successive Legislatures process for amending the 1887 Constitution by announcing a new constitution in place of Kalākaua’s 1887 Constitution.” (UH Law School)
• “She did not do so because the Cabinet she appointed on January 13, 1893, refused her authorization request. The members of that Cabinet were Samuel Parker, William Henry Cornwell, Jr,, Arthur P. Peterson and John Colburn. Parker was a Native Hawaiian.” (UH Law School)
Some Native Hawaiian Dissatisfaction with the Acts of Kalākaua and Lili‘uokalani
• Robert W Wilcox – the man who figured so prominently & conspicuously in the revolution of 1889 (All quotes from Wilcox, Morgan Report)
o “Queen Lili‘uokalani brought these evils upon herself and the country both by her personal corruption, and that of her Government.”
o “I believe that if we can be annexed to the United States, the rights of all of our citizens, and especially those of the native Hawaiians, will be protected more carefully than they have ever been under the monarchy.”
o “They are naturally somewhat prejudiced against (the Provisional Government), as monarchy is the only form of Government with which they are familiar, but this feeling will quickly wear away as the Hawaiians are led to see that the Government is friendly to them and their interests. They already have confidence in the integrity and patriotism of President Dole.
o “I have repeatedly (advocated annexation to the United States) in public meetings held in this city. … but I am compelled to move cautiously or I shall lose my influence over them. I believe I am doing a good work by constantly conversing with them on the subject.”
o “I have told my countrymen that the monarchy is gone forever, and when they ask me what is the best thing to follow it I tell them annexation, and I firmly believe that in a very short time every Hawaiian will be in favor of that step.” (Robert W Wilcox – the man who figured so prominently & conspicuously in the revolution of 1889; Morgan Report)
Repeated Changes in Cabinet Ministers in the Kalākaua and Lili‘uokalani Reigns
• “Under every constitution prior to 1887 the ministers were appointed by the King and removed by him; but until Kalākaua’s reign it was a very rare thing that any King changed his ministry. They had a pretty long lease of political life.” (Judd; Blount Report)
• “It was a very rare political occurrence, and made a great sensation when a change was made.” (Judd; Blount Report) if
January 14, 1893 Lili‘uokalani’s Ministers Refused to Support Her Constitution – Threats of Bloodshed were Made Against Her Cabinet Ministers
• “The Queen retired to the blue room and summoned the ministers (Samuel Parker – Minister of Foreign Affairs; John F Colburn – Minister of Interior; William H Crowell – Minister of Finance; Arthur P Peterson – Attorney General) who repaired at once to the palace. The Queen was at a table, still dressed in the magnificent costume of the morning, and sparkling in a coronet of diamonds.”
• “She at once presented them with the draft of the new constitution, demanded their signatures, and declared her intention to promulgate the same at once.”
• “Attorney-general Peterson and Minister of Interior Colburn decidedly refused to do so, and Ministers Cornwell and Parker, though more hesitatingly, joined their colleagues in this refusal.”
The Provisional Government (and subsequent Republic, Territory & State) did not steal the land from the Hawaiian people – Crown Lands Remain in the Public Trust
• Crown and Government Lands, though under the control of changing sovereigns and governments (Kingdom to Provisional Government to Republic to Territory to State,) were in and continue to remain in the ‘public domain’ for the public good.
• US Court of Claims concluded, “The constitution of the Republic of Hawai‘i, as respects the crown lands, provided as follows: ‘That portion of the public domain heretofore known as crown land is hereby declared to have been heretofore, and now to be, the property of the Hawaiian Government …” (Lili‘uokalani v The United States, 1910)
• We now generally refer to the Crown and Government Lands as ‘ceded’ lands. Under the Admission Act, about 1.2-million acres are to “be held by (the) State as a public trust” to promote one or more of five purposes:
o support of the public schools and other public educational institutions
o betterment of the conditions of native Hawaiians (per the Hawaiian Homes Act, 1920)
o development of farm and home ownership on as widespread a basis as possible
o making of public improvements
o provision of lands for public use
The United States does not have to acquire property only through a Treaty of Annexation with a concurring vote by the US Senate.
• Annexation of Hawai‘i to the US was not a hostile takeover, it was something the Republic of Hawai‘i sought. “There was no ‘conquest’ by force in the annexation of the Hawaiian Islands nor ‘holding as conquered territory;’ they (Republic of Hawai‘i) came to the United States in the same way that Florida did, to wit, by voluntary cession”. (Territorial Supreme Court; Albany Law Journal)
• “There is no provision in the Constitution by which the national government is specifically authorized to acquire territory; and only by a great effort of the imagination can the substantive power to do so be found in the terms of any or all of the enumerated powers.” (Legal Issues Raised by Proposed Presidential Proclamation To Extend the Territorial Sea, October 4, 1988)

The eruption of Vesuvius in 79 C.E. prompted the first scientific expedition (by Pliny the Elder) to study volcanic phenomena, as well as the first written eyewitness account (by Pliny the Younger) of eruptive activity.
The new science of geology emerged in the 19th century, focusing on the deduction of past events from current Earth exposures – “the present is the key to the past.” (Tilling)
The history of Hawaiian Volcano Observatory (HVO) begins with a geologist named Thomas A Jaggar, who witnessed the deadly aftermath of volcanic and seismic activity during a decade-long exploration of volcanoes around the world.
The devastation he observed, particularly that caused by the 1902 eruption of Mount Pelée on the Caribbean Island of Martinique, led Jaggar to his vision and life-long work to “protect life and property on the basis of sound scientific achievement” by establishing Earth observatories throughout the world. (USGS)
At that time, there was only one volcano observatory in the world – at Vesuvius, established in 1841 under King Fernando II to keep an eye on the active volcanoes near Naples. Jaggar thought America needed one. (Apple)
In early 1911, Jaggar convinced Frank A Perret, a world-famous American volcanologist he had met on Vesuvius Volcano in Italy, to travel to Hawai‘i to begin the observations of Kīlauea’s volcanic activity.
From July to October 1911, Perret conducted experiments and documented the lava lake activity within Kïlauea’s Halema‘uma‘u Crater, paving the way for Jaggar to pursue his life’s goal of using multiple scientific approaches and all available tools for the observation and measurement of volcanoes and earthquakes.
In 1911, the first scientific laboratory at Kilauea consisted of a crude wooden shack constructed on the edge of Halema‘uma‘u that was called the Technology Station. The next year saw the construction by Jaggar of the Hawaiian Volcano Observatory.
(Subsequently, the Technology Station was relocated and improved, and a structure called the “Instrument Shelter” (extending over the rim of Halemaʻumaʻu) was built with a wall open to the crater for a wide-angle view.)
Jaggar arrived at the Volcano House hotel on January 17, 1912; the Hawaiian Volcano Observatory was established by Jaggar, and for the first seven years of its existence it operated on funds provided by the Massachusetts Institute of Technology (MIT) from its Whitney Fund for research in geophysics and by the Hawaiian Volcano Research Association.
The latter is a group of persons, largely residents of Hawaii and principally businessmen, who are actively interested in the study of volcanoes.
“There is no place on the globe so favorable for systematic study of volcanology and the relations of local earthquakes to volcanoes as in Hawaii … where the earth’s primitive processes are at work making new land and adding new gases to the atmosphere.” (Thomas A Jaggar, 1916)
Upon his arrival, he established a routine of daily observations of the ongoing eruption in Halemaʻumaʻu Crater. “Keep and publish careful records, invite the whole world of science to co-operate, and interest the business man.” (Jaggar, 1913)
He developed uniform note pads with detachable sheets for use by all employees and insisted that anyone from the observatory who visited the crater take notes of their observations.
In 1919 the administration of the Volcano Observatory was taken over by the United States Weather Bureau, which was then charged by Congress with the responsibility for earthquake investigations in the United States.
In 1924 the Observatory passed to the US Geological Survey, in 1935 to the National Park Service, and in 1948 back to the Geological Survey. It is currently a part of the Geological Survey’s volcano investigation program.
The original location of the Volcano Observatory was the site now occupied by the Volcano House. The Whitney Laboratory of Seismology is a concrete vault beneath the western end of the Volcano House. (The vault is under the grassy mound on the Halema‘uma‘u side of the hotel.)
When the present Volcano House was built in 1941, the Observatory was transferred to what is now the Park Museum and Administration Building, and in 1948 to a building on the western rim of Kilauea caldera at Uekahuna. Dr Jaggar continued as Director of the Observatory until his retirement in 1940.
Since 1912, Kilauea and Mauna Loa volcanoes have been under constant close observation by members of the Observatory staff. The purpose of the studies by the Volcano Observatory have two general aspects, the humanitarian or practical aspect and the strictly scientific.
The two are difficult to separate, because a phase that belongs to pure science today may become of great practical importance within a few years.
In general, the scientific aspects of the Observatory program are directed toward an understanding of the subsurface structure of the volcanoes, the nature and properties of the magma, how the volcano behaves, and why.
The humanitarian aspects include prediction of eruptions and the course of lava flows once the eruption has started and issuing warnings of danger from lava flows.
An example of one phase of the Observatory’s program that is of purely scientific importance is the investigation of the volcanic gases and their relation to the magma and effects on surrounding rocks.
The Observatory also makes visual observations of the volcanic eruptions, collects gas and lava samples, determines temperatures of liquid and solidifying lava and of the gases, measures the width of many cracks about Kilauea caldera as they open and close, operate tilt-meters and a series of magnetometer stations on Kilauea and the slopes of Mauna Loa, and a net of seismograph stations.
Very early in the history of the Observatory it was found that the ground surface on the slopes of the volcano was constantly tilting in one direction or another, and it was soon shown that this tilting correlated with activity of the volcanoes.
Preceding eruption the whole volcano swells up, as though it were being inflated like a big balloon. This produces an outward tilting on its sides. Following the eruption the volcano contracts and the slopes tilt inward.
This swelling and tilting can be measured by leveling, of the sort done in ordinary surveying. By leveling from sea-level at Hilo, it was found that during the interval from 1912 to 1921 a bench mark near the Observatory apparently rose about 3 feet.
Releveling in 1927, after the great collapse and steam explosions of 1924, showed that the same bench mark had lowered 3.5 feet, while a bench mark near the rim of Halema‘uma‘u had gone down about 13 feet.
Ordinarily, however, the tilting of the ground surface is measured not by leveling, but by sensitive pendulums known as tilt-meters. Such tilt-meters in operation by the Observatory are capable of indicating an angle of tilt of less than one-tenth of a second. (A tilt of one-tenth of a second would displace the top of a pole ten miles high about a quarter of an inch).
Volcanic tilt of many seconds of arc has been measured on the tilt-meters. Strong outward tilting of the ground surface, especially when combined with numerous earthquakes, is a good indication of magma rising in the volcano and the possibility of impending eruption.
Magnetometer measurements by the Volcano Observatory were started early in 1950. A magnetometer is an instrument used to measure the strength of the earth’s magnetic attraction at any given locality. The strength of the earth magnetism depends on several factors.
One cause of decrease in the strength of magnetism is rise in temperature of the underlying rock. As magma rises beneath the surface the surrounding rocks are heated up, and their magnetism decreases. Detecting this aids in prediction of eruptions.
A seismograph is a device to record earthquakes. The essential portion of most seismographs is a pendulum. Because of its inertia, during earthquakes a freely suspended pendulum tends to stand still while the earth moves under it.
The effect is nearly the same at it would be if the earth were still and the pendulum vibrating. This apparent movement of the pendulum is recorded in various ways – by direct mechanical means, by directing a beam of light onto photographic paper, or electrically.
So long as the earth is quiet the writing point draws a straight line on the smoked paper, but when an earthquake occurs the pendulum vibrates with respect to the ground and the recording drum, and the line drawn on the smoked paper is wiggly.
By identifying the times of arrival of the different types of vibration, and measuring the interval of time between them, the distance from the station at which the earthquake originated can be calculated. Then, by using the distances of origin from several stations, the epicenter and depth of origin of the earthquake can be located.
Any marked increase in the number of earthquakes indicates a restlessness of the volcano in which the earthquakes originate, and the location of the earthquake indicates what portion of the volcano is involved. Commonly an eruption of either volcano is preceded by a series of earthquakes.
These earthquakes begin at a depth of 25 to 30 miles, but as the series progresses the places of origin get gradually closer to the surface and often shift laterally, finally centering at a place close to the site of the coming eruption. Thus, earthquakes are of great value to the volcanologist in predicting coming activity. (Information is copied from NPS, Nature Notes May 1951)
During the past century, HVO has been at the forefront of developing and applying the modern techniques and instruments now used in volcano monitoring, including volcanic-gas monitors, satellite-based deformation measurements, networks of remote cameras recording eruptive activity, and seismic networks such as the Hawai‘i Regional Seismic Network.
The first seismic network in the USGS was installed on Kīlauea in the 1950s, and earthquake monitoring has been important both as a tool for volcano monitoring and for assessing seismic hazards in the State of Hawaii. HVO has been a training ground for volcanologists from the United States and around the world.
By December 1915, with Jaggar having worked in Hawai‘i for three years, the Research Association and MIT sent him to Washington DC to appeal to Congress to take over HVO as a government institution. In addition, the governor of Hawai‘i and the Honolulu Chamber of Commerce asked him to continue to push for the establishment of a national park. (Moniz Namakura)
(On August 1, 1916, President Woodrow Wilson signed the bill establishing Hawaii National Park as the nation’s 13th national park. It included lands surrounding Kīlauea and Mauna Loa volcanoes on Hawaiʻi Island, and Haleakalā on the island of Maui. In July 1961, Hawai‘i National Park was split into two distinct areas: Haleakalā National Park and Hawai‘i Volcanoes National Park.)
The US Geological Survey (USGS) has operated HVO continuously since 1947. Before then, HVO was under the administration of various Federal agencies – the US Weather Bureau, at the time part of the Department of Agriculture, from 1919 to 1924; the USGS, which first managed HVO from 1924 to 1935; and the National Park Service from 1935 to 1947.
It currently operates under the direction of the USGS Volcano Science Center, which now supports five volcano observatories covering six US areas – Hawaiʻi (HVO), Alaska and the Northern Mariana Islands (Alaska Volcano Observatory), Washington and Oregon (Cascades Volcano Observatory), California (California Volcano Observatory), and the Yellowstone region (Yellowstone Volcano Observatory).
For much of its history, HVO was perched dramatically on the rim of Kīlauea Volcano’s summit caldera inside Hawai‘i Volcanoes National Park. That ended in 2018, when – amid ash explosions and violent earthquakes accompanying onset of partial summit collapse – HVO relocated to the town of Hilo, 30 miles distant.
Due to substantial damage to the building, new facilities in Hilo and inside the national park are planned. In the meantime, most of HVO remains in Hilo in the historic Ironworks Building on Kamehameha Avenue. HVO continues to use some facilities inside the national park and a warehouse in Kea‘au. (USGS)
