Mauna Loa

July 22, 2025 by Peter T Young Leave a Comment

Mauna Loa (“long mountain”) is the world’s largest active volcano and probably the largest single mountain mass of any sort on earth. It rises 13,679-feet above sea level, and about 31,000-feet above its base at the ocean floor.

(Of course this relates to surface volcanoes – Tamu Massif, a rounded dome in the northwest Pacific, measures about 280 by 400 miles, or more than 100,000 square miles and lies about 6,500 feet below the ocean surface (Mauna Loa measures about 2,000 square miles.))

Mauna Loa’s volume is of the order of 10,000 cubic miles, as compared to 80 cubic miles for the big cone of Mount Shasta in California. This huge bulk has been built almost entirely by the accumulation of thousands of thin flows of lava, the individual flows averaging only about 10 feet in thickness. (NPS)

The enormous volcano covers half of the Island of Hawai`i and by itself amounts to about 85 percent of all the other Hawaiian Islands combined. (USGS)

Mauna Loa has grown rapidly during its relatively short (600,000 to 1,000,000-years) history. Detailed geologic research on the volcano has nevertheless shown that about 98-percent of the volcano’s surface is covered with lava flows less than 10,000 years old. (USGS)

Since 1832, Mauna Loa has erupted 39 times; its last eruption started in 1984. According to USGS estimates, the volcano has erupted an average of once every 6 years over the past 3000. (SOEST)

The Ahupua‘a of Kapapala encompasses both the summit area and eastern flanks of Mauna Loa; this relatively large ahupua‘a extends from the coastline (Nāpu‘uonā‘elemākule to Keauhou) to the summit of Mauna Loa and Moku‘āweoweo Caldera. (NPS)

The large size of the ahupua‘a may be accounted for because the area contains limited natural resources within its boundaries: coastal resources most likely provided residences with rich marine resources; upland areas were rich in forest resources (e.g. forest birds, canoe material). However, the remaining portions of the ahupua‘a include the vast Ka‘u desert. (NPS)

The first modern climb of Mauna Loa was made by Archibald Menzies, the acclaimed naturalist and botanist serving with Captain George Vancouver on the Discovery.

In February 1794, after receiving advice and assistance from King Kamehameha (guides, attendants and transportation to the southern point of the island,) Menzies and the team reached the summit (fueled by rations consisting of few ship’s biscuits, a bottle of rum, some chocolate and a few coconuts.) (NPS)

Later, between December 1840 and January 1841, the US Exploring Expedition, led by Lt. Charles Wilkes, was the first US exploring and surveying expedition to the South Seas.

“(I)t was my intention to proceed to Hawaiʻi, there to ascend to the top of Mauna Loa; to make the pendulum observations on the summit and at the base of that mountain; to examine the craters and late eruptions”. (Wilkes 1845)

The expedition team was supported by a throng of porters that stretched out across the landscape and Wilkes described the scene as consisting of “…200 bearers of burdens, forty hogs, a bullock and bullock hunter …”

“… fifty bearers of poe (native food), twenty-five with calabashes…lame horses, which, instead of carrying their riders, were led by them; besides a large number of hangers-on, in the shape of mothers, wives, and children, equaling in number the bearers, all grumbling and complaining of their loads…”(Wilkes, NPS)

Once at the summit, a camp (called Pendulum Peak) was set up with rock walls to buttress tents against the extreme weather conditions, and the expedition could carry out observations and mapping.

The expedition mapped the summit region and conducted scientific efforts in the relatively unknown alpine wilderness area. The culmination of the Expedition coincided with the establishment of the Smithsonian Institution and the Natural Museum of Natural History. (NPS)

Land Commission testimony (1845) notes that sandalwood was an important resource, “When the people used to go after sandalwood the Alii of Kapapala Naihe and Aikanaka took it for Kaaumanu.”

“The Kaalaala people went after sandalwood for their chief but the people of the other lands in Kau used to go after sandalwood on Kapapala and take to their chiefs. This was the last gathering of sandalwood for Kamehameha III to pay the debt.” (NPS)

After the Mahele of 1848, the lands of Kapapala were retained as crown lands under Kauikeaouli (Kamehameha III). Upon his death, the title to the land was transferred to his successor, Kamehameha IV, who ruled the islands from 1854-1863. The land remained as crown lands until the overthrow of the Hawaii Monarchy in 1893. (NPS)

Others later climbed the mountain: “Struggling, slipping, tumbling, jumping, ledge after ledge was surmounted, but still, upheaved against the glittering sky, rose new difficulties to be overcome. Immense bubbles have risen from the confused masses, and bursting, have yawned apart.…”

“Earthquakes have riven the mountain, splitting its sides and opening deep crevasses, which must be leapt or circumvented. … stepping over deep cracks, which, perhaps, led down to the burning, fathomless sea, traversing hilly lakes ruptured by earthquakes …”

“… and split in cooling into a thousand fissures, painfully toiling up the sides of the mounds of scoriae frothed with pumice-stone, and again for miles surmounting rolling surfaces of billowy, ropy lava – so passed the long day, under the tropic sun and the deep blue sky.” (Isabella Bird, 1875)

Starting in 1906, George Lycurgus (early operator of the Volcano House) and newspaperman Lorrin Andrews Thurston were working to have the Mauna Loa and Kilauea Volcanoes area made into a National Park. In 1912, geologist Thomas Augustus Jaggar arrived to investigate and joined their effort.

In September 1915, Jaggar, Thurston and a US Army representative conducted a survey to determine a route for a trail up Mauna Loa. The following month, a local paper noted, “Soldiers Building Mountain Trail. Negro soldiers of the Twenty-fifth Infantry to the number of 150 are at work constructing a trail from near the Volcano House to the summit of Mauna Loa.”

“It is estimated that three or four weeks will be devoted to this work. The soldiers are doing the work as a part of their vacation exercises.” (Maui News, October 29, 1915)

The Buffalo Soldiers built the 18-mile trail to the summit of Mauna Loa. They also built the ten-man Red Hill Cabin and a twelve-horse stable, so scientists could spend extended periods of time studying the volcano.

On August 1, 1916, President Woodrow Wilson signed the country’s 13th National Park into existence – Hawaiʻi National Park. At first, the park consisted of only the summits of Kīlauea and Mauna Loa on Hawaiʻi and Haleakalā on Maui. On, July 1, 1961, Hawaiʻi National Park’s units were separated and re-designated as Haleakalā National Park and Hawaiʻi Volcanoes National Park.

Ohia Lodge

“For a number of years prior to the beginning of [WWII], home building was curtailed, and such materials as might normally be needed to meet the housing requirements of a growing population were diverted to national defense … these materials were actually frozen.” (DOI Annual Report, 1946)

Then, in post-WWII, “During the past year [1946] the problem has become even more serious. The Governor’s housing committee and a committee of the chamber of commerce of Honolulu, after a careful study, reported that 11,000 additional houses were needed”.

“A number of factors have militated against an adequate home-building program. The most important of these are: (a) scarcity of land even at an extremely high price, (b) unavailability of building materials, and (c) shortage and high cost of labor.” (DOI Annual Report, 1946)

“Two enterprising Honolulu business men, with faith in the future of Kona … have licked the building material shortage by using their brains and brawn. The are Howard O Redfearn, the former Honolulu contractor, and Chester Horn …”

“About the first of the year they started to work to create the timber and other material necessary for the construction of their Ohia Lodge, on Redfearn’s 350-acre tract in South Kona …”

“They were unable to procure material at that time, so set about making their own. First Redfearn moved his sawmill to the site and set it up. Then the two men went to work with ax and saw cutting down ohia trees, which grow in abundance on the tract. They selected uniform size and then trimmed off the bark and sawed the log in half.”

“With these halves, placed upright, they began the construction of the first lodge, which is 24 by 50 feet. … The interior of the building, including the bar, the tables, doors, bar stools and kitchen are built of koa and ohia.”

“The koa was obtained from a nearby forest but the ohia wood all came from the Redfearn ranch. … The floor is cement but is waxed for dancing. The foundation and all the masonry has been constructed from rocks gathered up on the place, as well as a great circular water tank, cemented inside …”

“A large parking space has been levelled off in front of the building and this will be paved. Around it there will be special landscaping and flower gardens.”

“The lodge bar will be opened for business [on May 29, 1947]. A little later the dining room, which will specialize in charcoal cooked steaks and short orders, will be opened. And as soon as possible a general liquor dispensary will be opened.” (Hilo Tribune Herald May 10, 1947)

“Plans have been prepared for the construction of 40 cottages in the rear of the lodge similar to many types seen on the mainland. These cottages will be 12×16 feet, and each will contain two three-quarter size beds, adequately spaced for privacy.”

“After the cottages have been constructed a modern gas station will be built, carrying all kinds of motor supplies. The whole setup will stimulate a miniature California Palm Springs, with mild desert air included.”

“Horn will be general manager. Orchestra music will be supplied every Saturday night and on any other occasion required.”

“As a special added attraction for tourists there will be saddle trails all over the tract so that guests will be able to go horseback riding at all times and since the tract is but a short distance from the sea arrangements to conduct fishing parties will be an added feature in the line of sports.” (Hilo Tribune Herald May 10, 1947)

‘Ōhia Lodge, the half-way house on the main highway between Hilo and Kona was “a showplace. Howard Redfearn built it as a volcano country club resort and opened it in [1947]. The lodge, built of Ohia, a native hardwood similar to mahogany, had a dining room seating 200 people.” (Spokesman-Review, Jun 6, 1950)

“[P]eople came from far and near to see for themselves what two men, alone and unaided, had accomplished in such a short time. … [I]t is so located that it gives a clear view of both the mountains and the sea, and is on the main highway into the Kona district.” (Hnl Adv, Aug 3, 1947)

“Mr Redfearn also revealed that he has begun the construction of another dwelling, to be occupied by Mr and Mrs William [and Helene] Hale, teachers at Konawaena school, and four tourist cabins …”

“… the first units of several to eventually be built for the convenience of tourists and others. Two dwellings have already been completed and occupied and a third is now under construction.” (Hilo Tribune Herald, Feb 24, 1949)

“The first three units of the proposed auto court at Ohia Lodge Kona is partially completed by Howard O Redfearn, proprietor of the lodge.”

“Work, however, has been temporarily suspended while Redfearn is engaged in the construction of a new … residence for Richard Penhallow at Waimea … This will be the fourth residence of the completed by Mr Redfearn of this unique design.” (Hilo Tribune Herald, Oct 1, 1949)

Then, disaster struck; Mauna Loa erupted … “Howard Redfearn’s handsome Ohia Lodge in South Kona was engulfed by lava between 8 and 9 last night. A fiery finger, separating from the main channel, moved steadily toward the lodge during the afternoon and finally reached the building, wiping out the Ohia and field stone structures.”

“It was the plan to expand Ohia lodge facilities with a group of tourist cabins. It is reported that two such cabins had been constructed before the lodge was destroyed by the flowing lava.” (Star Bulletin, Jun 5, 1950)

Six Active Volcanoes in Hawai‘i

The Hawaiian Islands are at the southeast end of a chain of volcanoes that began to form more than 70 million years ago. Each island is made of one or more volcanoes, which first erupted on the floor of the Pacific Ocean and emerged above sea level only after countless eruptions.

Hawaiʻi sits over a ‘hot spot,’ the Hawaiian hot spot.

It’s one hot spot, but lots of volcanoes have formed over it. The Islands are above a moving sea floor of the North Pacific Ocean (the Pacific Ocean is mostly floored by a single tectonic plate known as the “Pacific Plate.”)

The Pacific Plate is moving over the layer in the Earth known as the Asthenosphere. This movement takes it to the northwest. As the plate moves over a fixed spot deeper in the Earth where magma (molten lava) forms, a new volcano can punch through this plate and create an island.

As the plate moves away, the volcano stops erupting and a new one is formed in its place. With time, the volcanoes keep drifting westward and getting older relative to the one active volcano that is over the hot spot.

As they age, the crust that they sit on cools and subsides. This, combined with erosion of the islands, once active volcanism stops, leads to a shrinking of the islands with age and their eventual submergence below the ocean surface.

Each island is made up of at least one primary volcano, although many islands are composites of more than one. The Big Island, for instance, is constructed of 5 major volcanoes: Kilauea, Mauna Loa, Mauna Kea, Hualālai and Kohala (the island is still growing, but is basically about 400,000-years old.)

About 40-million years ago, the Pacific Plate changed direction from north to northwest – so the Emperor Seamounts run more north-south, the Hawaiian Ridge north-westerly.

Midway Island is 27.7-million years old; Meiji Seamount the northern part of the Emperor Seamount (near the end of the Aleutian chain) is about 80-million years old.

All of these are still youngsters, when you look at the perspective, say, of the dinosaurs. The Islands weren’t even a glimmer in anyone’s eyes when dinosaurs walked the Earth; sixty-five million years ago the last of the non-avian dinosaurs went extinct, after living on Earth for about 165-million years. (USGS)

If all of Earth time from the very beginning of the dinosaurs to today were compressed into 365 days (1 calendar year), the dinosaurs appeared January 1 and became extinct the third week of September.

Using this same time scale, the Earth would have formed approximately 18.5-years earlier. By comparison, people have been on earth only since December 31 (New Year’s eve.) (USGS)

While we typically think of and/or hear news reports of eruptions on Kilauea and Maunaloa, presently, the US Geological Survey (USGS) Hawaiian Volcano Observatory (HVO) monitors the six currently active volcanoes in Hawai‘i.

The Island of Hawai‘i, with four active volcanoes, is liveliest. Between 1912 and 2012, there were nearly 50 Kīlauea eruptions, 12 Mauna Loa eruptions, and one Hualālai intrusion of magma.

Kīlauea, the youngest and most active volcano on the Island of Hawai‘i, erupted almost continuously from 1983 to 2018 at Pu‘u‘ō‘ō and other vents along the volcano’s East Rift Zone. Since then, there have been periodic eruptions in and nearby Halema‘uma‘u crater at the volcano’s summit.

In 2018, Kīlauea experienced the largest lower East Rift Zone eruption and summit collapse in at least 200 years. Several summit eruptions since December 2020 have generated lava lakes that have been slowly filling in the collapsed area, including Halema‘uma‘u crater. About 90 percent of the volcano is covered with lava flows less than 1,100 years in age.

Mauna Loa, the largest volcano on Earth, has erupted 34 times since 1843. An eruption 1984 lasted 22 days and produced lava flows which reached to within about 4.5 miles of Hilo, the largest population center on the Island of Hawai‘i.

The most recent eruption in 2022 lasted two weeks and erupted lava flows that came to within 1.7 miles of the Daniel K Inouye Highway (Saddle Road). Lava flows less than 4,000 years old cover about 90 percent of the volcano.

Hualālai, the third most active volcano on the Island of Hawai‘i, has erupted three times in the past 1,000 years and eight times in the past 1,500 years.

The most recent eruption in 1801 generated a lava flow that reached the ocean and now underlies the Kona International Airport. Lava flows less than 5,000 years old cover about 80 percent of the volcano.

Mauna Kea, the highest volcano on the Island of Hawai‘i, erupted most recently between about 6,000 and 4,500 years ago from at least seven separate summit-area vents, producing lava flows and cinder cones. Glaciers covered parts of the volcano’s summit area during the recent ice ages, the only Hawaiian volcano known to have been glaciated.

Kama‘ehuakanaloa (formerly Lō‘ihi Seamount), the only known active Hawaiian submarine volcano, erupted most recently in 1996 during an earthquake swarm of more than 4,000 events that were recorded by the HVO seismic network. The volcano’s summit is about 3,179 ft below sea level, located 22 miles southeast of the Island of Hawai‘i.

Haleakalā, the only active volcano on the Island of Maui, erupted most recently between about 600 and 400 years ago. In the past 1,000 years, at least 10 eruptions produced lava flows and tephra cones from the rift zone that crosses the volcano from southwest to east and through Haleakalā Crater.

Buffalo Soldiers Trail

In early 1911, geologist named Thomas A 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.

When Jaggar came to the Islands, he joined the efforts of George Lycurgus (operator of the Volcano House) and newspaperman Lorrin Andrews Thurston who were working to have the Mauna Loa and Kilauea Volcanoes area made into a National Park.

Jaggar had tried to lead several expeditions to the top of Mauna Loa in 1914 but was unsuccessful due to the elevation (13,678 feet) and the harsh conditions: rough lava, violent winds, noxious fumes, shifting weather, extreme temperatures and a lack of shelter, water and food. (Takara)

In September 1915, Jaggar, Thurston and a US Army representative conducted a survey to determine a route for a trail up Mauna Loa.

The following month, a local paper noted, “Soldiers Building Mountain Trail. Negro soldiers of the Twenty-fifth Infantry to the number of 150 are at work constructing a trail from near the Volcano House to the summit of Mauna Loa.”

“It is estimated that three or four weeks will be devoted to this work. The soldiers are doing the work as a part of their vacation exercises.” (Maui News, October 29, 1915)

Immediately after the Civil War and the abolition of slavery, many African Americans found themselves newly freed from bondage. In 1866, congress created four military regiments made up of Black troops, the 9th and 10th Cavalry and the 24th and 25th Infantry – they were known colloquially as the Buffalo Soldiers. (NPS)

“Although Native Americans bestowed the name upon the troopers, there are differing accounts as to the reason. One account suggests the name was acquired during the 1871 campaign against the Comanches, when Indians referred to the cavalrymen as “Buffalo Soldiers” because of their rugged and tireless marching.”

“Other accounts state that Native Americans bestowed the nickname on the black troopers because they believed the hair of the black cavalrymen resembled the hair of the buffalo.”

“Another suggests that the name was given because of the buffalo-hide coats worn by the soldiers in cold weather. The troopers took the nickname as a sign of respect from Native Americans, who held great reverence for the buffalo, and eventually the Tenth Cavalry adopted the buffalo as part of its regimental crest.” (Plante)

“The generous cooperation of the United States Army has made the trail to the top of Mauna Loa and the rest houses at the top and midway thereto a certainty.” (Hawaiian Gazette, Sep 24, 1915)

“The overpowering feature of the landscape, however, is the immediate foreground to the north and east. The trail up to Red Crater is through ordinary and rather monotonous lava flows; but from the top of the hill there literally bursts into view a scene of most violent volcanic activity that I have seen anywhere.”

“It is similar to the interior of Haleakala crater; and the top of Hualalai, but while those are old and faded, this is fiery red and inky black.” (Hawaiian Gazette, Nov 11, 1915)

“During the past summer [in 1915] the promotion committee and Research Association formulated and presented its plan to the authorities of the County of Hawaii and the newly created Hawaii Publicity Committee …”

“… proposing that these two organizations with the assistance of private subscriptions should furnish the money necessary for the material involved, the work to be done by the county prisoners.”

“The county authorities and the publicity committee each agreed to contribute $500 toward the enterprise. Then the Governor came in with a contribution of $500 from the contingent fund and private subscriptions have been received in excess of $1000.”

“No decision had been arrived at concerning the availability of the county prisoners, however.” (Hawaiian Gazette, Sep 24, 1915) (The practice in Hawai‘i and elsewhere was to use prison labor for public works projects, including road building.)

(Later Territorial law stated, “All prisoners sentenced to imprisonment at hard labor shall be constantly employed for the public benefit, on public roads or other public works or other wise, as the high sheriff, with the approval and subject to the control of the board of prison directors, may deem best.”)

Then the military offered aid in the form of a “tentative proposition that, if transportation was furnished from Honolulu to Hilo and return, Company E of the Twenty-fifth Infantry, consisting of between 140 and 150 men would volunteer to go to Volcano, and do the work of building the trail and erecting the rest houses without further expense to the promoters or enterprise.” (Hawaiian Gazette, Sep 24, 1915)

Building the Buffalo Soldiers Trail (now called Mauna Loa Trail) from the 4,000-ft. summit of Kīlauea to the 13,677-ft. summit of Mauna Loa was no easy task. (NPS)

“The soldiers are constructing a trial three feet wide across the a-a, crushing it down with twelve pound hammers, filling in hollow, cutting down ridges and putting on a finish of fine a-a and earth, quarried along the line or parked in gunny sacks, carried on the men’s backs – in some places being carried as far as a quarter of a mile.”

“The Mauna Loa trail and rest house project is making steady and substantial progress. It must be remembered that it is through a section of territory never before inspected, much less traveled over, except the lower portion thereof, and that only by a few surveyors, cattle men and catchers of wild goats.”

“No one wants to run away with the idea that the job which the men of Company E of the Twenty-fifth Infantry have volunteered to do is all picnic. They are having a picnic all right; but incidentally they are doing a lot of good hard work in a pure pro bono publico spirit.” (Hawaiian Gazette, Nov 11, 1915)

“[D]uring the period of 1915 to 1921, the trail was managed and maintained by a loose consortium consisting of Hawaii Volcano Research Association, Lorrin Thurston, Hilo businessmen, and Thomas Jaggar, then it was managed by the National Park Service.” (Tuggle)

Between 1930 and 1932, the National Park carried out major improvements and realignments of the Mauna Loa Trail to fall completely within the park boundary. Over the past century, the evolving needs of the National Park and changes in available

technology have resulted in ongoing modifications to the physical footprint of the trail.

The uppermost portion of the original trail footprint has been nearly obliterated since the 1970s by a series of large lava flows in 1975, 1984, and 1985. (Tuggle) (The inspiration and sources to information here came primarily from a study by Myra Tomonari-Tuggle.)

St Peter’s Chapel

“There are a few, very small fishing villages, Alae, Alika and Papa, which are reached by poor trails from the mauka road. It is necessary to travel from Hookena mauka to the main road to Papa, and thence by either road or trail to Hoopuloa, the last steamship landing in Kona.”

“This is another village which is dwindling in population, only a few Hawaiians and a couple of Chinese storekeepers remaining. A fair road leads across a barren a-a flow to Miloli‘i, the largest and best specimen of an exclusively Hawaiian village on the Island, which is seldom visited.”

“It is splendidly situated by a sand beach, the sea coming right up to the yard wall, and is inhabited by a rather large population of Hawaiians, who prosper through the fishing which is almost phenomenally good…”

“This region is seldom visited. Its chief points of interest are the remains of a heiau, mauka of the Catholic church at Milolii, some fine papa konane at the south end of the same village a well preserved kuula (still used) where fishermen offer offerings of fruit to insure a good catch, by the beach south of Milolii, where the Honomalino Ranch fence crosses the trail; while all along the trail are smaller kuulas, and at many points the foundations of villages, where old implements may still be found.” (Kinney, 1913)

“Hoopuloa was one of the few typically Hawaiian villages remaining in Hawaii. It comprised of a cluster of 10 to 15 homes of old Hawaiian style and boasted a population of approximately 100 persons … The wharf was a port of call for the Inter-Island steamers”. (Honolulu Star Bulletin, April 19, 1926)

Then … “The number of earthquakes recorded for April [1926] was 671 (compared with monthly average of 52 for the preceding 3 months. … The maximum daily frequency of earthquakes in the 1926 eruption was on April 15 (86 shock), the first day of free-flowing flank eruption …” (Jaggar)

Edward G Wingate, USGS topographical engineer, was mapping the summit of Mauna Loa in 1926, changing campsites as the work progressed. On April 10 his camp was along the 11,400-foot elevation, well into the desolate upland above the Kau District.

An earthquake wakened the campers about 0145; as they drifted back to sleep, a further series of quakes had them sitting up, talking, and wondering. About 0330 Wingate braved the cold and wind; with a blanket wrapped around him, he went outside and stood bathed in reddish light. (USGS)

There was a brief summit eruption, followed by 14 days of eruption on the southwest rift zone. “About 3 am April 10 (1926,) glowing lava spouted along the upper 3 miles of cones and pits of the Mauna Loa rift belt, immediately south of Mokuʻāweoweo, the summit crater. … The actual beginning shown at Kilauea by seismographic tremor was 1:36 am, followed by two pronounced earthquakes.” (Jaggar)

For three days the HVO party surveyed the sources of the eruption; then they descended and moved into Kona District, where roads, houses, and other property were threatened by the flows. Wingate and his crew stayed behind. Much of the area already mapped was under fresh lava, and there was a lot of remapping to do. (USGS)

“A crack only 1 to 3 feet wide opened southward from a point tangent to the ease edge of the bottom of the south pit of Mokuʻāweoweo, vomited out pumiceous silvery pāhoehoe froth lava, and extended itself S.30^oW. past the next two pits and over the brow of the mountain down to an elevation of 12,400 feet.” (Jaggar)

“Fortunately the main gushing of this first phase ceased about 5 am the same forenoon, after flowing 5 hours. … (Then,) The vent crack was splitting itself open downhill. The source pāhoehoe changed itself by stirring into scoriaceous aa half a mile from the vents”. (Jaggar)

“When it got close to the upland of Hoʻopuloa, the flow of lava separated into two, and one of the flows went straight for the village of Hoʻopuloa and the harbor, and the second flow went towards the village of Miloliʻi.” (Hoku o Hawaii, April 20, 1926)

“(T)he Honomalino flow to the west finally dominated, … This was also aa. … It crossed the belt road at 12:22 pm April 16, 3 miles above Hoʻopuloa village.” (Jaggar)

On April 16, Jaggar scratched marks about a foot apart across the rutted, gravel road (the only road) between the Kona and Kau Districts. A lava flow was approaching, and Jaggar wanted to measure the flow’s speed as it crossed the road.

St Peter’s Chapel, sometimes referred to as Ho‘opuloa Catholic Church, was on the makai side of the road. Perhaps a hundred people were waiting around the Hoʻopuloa Church, on the uphill side of the road, and at the Kana‘ana house opposite, on the downhill side of the road.

They had seen and heard the flow, 15-20 feet high and more than 500 feet wide, as it moved through the forest uphill. When it neared the road, people who lived on the Kona side of the flow moved off to the north, and those who lived on the Ka‘u side moved to the south, so they could go home after the road was closed. (USGS)

Jaggar recorded that it reached the uphill, inland side of the road at 12:22 at an estimated speed of about 7 feet/minute; within two minutes the road was crossed. Jaggar and his assistant, HS Palmer, stayed on the Ka‘u side. (USGS) St Peter’s Chapel, sometimes referred to as Ho‘opuloa Catholic Church, was on the makai side of the road.

“The Catholic church, where many Hawaiians worshipped, was one of the first building to be destroyed in the flow which buried Hoopuloa.” (The Star, NZ, May 21, 1926)

“It is true that I saw the church destroyed by the lava tide, which moved onward with irrevocable majesty, entering the house of worship by way of the open front door.”

“Through the windows I observed the red mass proceed to the alter as the whole structure, capable of seating 20 worshipers, burst into flames.”

“Most dramatic of all was the moment when the slow moving red-hot deluge, pressed on by the mass of lava from the rear, tipped the church from its foundations and set it careening upon the molten river.”

“Straightaway, the bell, which hung in an open steeple, began ringing. It pealed above the roar of the flames and the grinding of the blazing substance surging onward.”

“A dozen doleful strokes of the iron tongue echoed farewell before it fell from the cross beam ringing its own requiem.” (Father Eugene Oehman, Honolulu Advertiser, July 31, 1932)

A memorial to the church was erected; the plaque on the monument reads “1926 Hoopuloa Catholic Church.” “Under the cross, 25 feet below the surface is all that remains of a small Catholic church, over which the lava flowed without a moment’s halt.” (Honolulu Advertiser, July 31, 1932)

“The fiery lava engulfed the harbor and village of Hoʻopuloa, and now they are but a heap of pāhoehoe lava.” (Hoku o Hawaii, April 20, 1926)
