Explosive eruptions do not generally come to mind when people think of Hawai‘i’s volcanoes. Their eruptions are typically characterized by the relatively quiet outflow of very fluid lava and by sometimes spectacular lava fountains.

Hawai‘i’s volcanoes have therefore become the textbook example of nonexplosive volcanism, and the term “Hawaiian type” is used to refer to such eruptions. Eruptions at Kilauea can often be observed safely at close range. (USGS)

The late 1780s were years of great strife on the Island of Hawai’i. Kamehameha, who later became the first king of the Hawaiian Islands, was at war with his rival Keōua. After one of several indecisive battles, probably in 1790, the balance was suddenly tipped in favor of Kamehameha when a natural disaster struck.

As a large group of Keōua’s warriors traveling with their families passed the crater of Kilauea Volcano, there was a sudden explosive eruption of searingly hot ash and gas. At least 80 and perhaps hundreds of people were killed in the deadliest historical eruption to occur in what is now the United States. (USGS)

During 18 days in May 1924, hundreds of steam explosions from Kilauea hurled mud, debris, and hot rocks weighing as much as 8 tons as far as two-thirds of a mile from the center of Halema‘uma‘u the current crater within the larger volcanic depression (caldera) at Kilauea’s summit.

Columns of volcanic ash and dust rose more than 2 miles into the air, at times turning day into night at the town of Pahala, nearly 20 miles downwind.

Only one person was killed during this eruption, a photographer who ventured too close and was struck by falling rocks and hot mud. (USGS)

The largest explosive event in 1924, on May 18, ejected blocks toward the southeast, including the eight-ton block, and killed Truman Taylor. (Pacific Parks)

Taylor Stearns notes in his autobiography, “[WO] Clark told me how he had brought Taylor, a clerk about twenty-seven years old from Pahala [he worked on the C. Brewer plantation], up to the volcano. Miss Bradfield, the local nurse, and her companion [Miss Peck] had been with them.”

“Taylor had borrowed Clark’s camera and tripod to take a close-up shot. [When the explosion began, Ted] Dranga and the two nurses ran to the Essex car nearby, which they had left running so as to make escape easy [those were the days of hand cranks].”

“When they reached the car the [others] wanted to start right away but Miss Bradfield said she didn’t want to leave with Taylor out there. She made them wait a minute, and then as the stones began to fall around them she decided it would be better to leave Taylor than for all to be killed.”

Per, “Ruy Finch, in the HVO journal: 10:36 a.m. With L.A. Thurston and W.O. Clark of Pahala. Large puffs of steam; rumbling, earthquake. Went to sand spit above Algae [an area of algae growing on the south-facing cliff, then known as the Italian cliff, that forms the south side of what is now known as Sand Spit] and sat down on a boulder which had been ejected at 12:30 p.m.”

“May 17. Numerous quakes and rumbling. Sent T. Dranga Jr., to get Thurston who was with Carlsmiths. A wave of increased air pressure that decidedly hurt my head, was felt at 11:09 a.m. Jumped and exclaimed, ‘Here comes a terrible one.’”

“The air pressure was felt several seconds before rocks appeared and two or three seconds before the explosion cloud cleared the rim. Started to take picture but saw rocks of great dimensions high in the air headed toward our locality.”

“Ran to cliff and slid down a wash. A rock, judging from its air appearance to have weighed over 300 lbs [135 kg] cleared the cliff and landed on 1921 lava. Left Thurston, Clark and ladies of Carlsmith party on cliff.”

“O Emerson in the afternoon reported a 10-ton rock on airplane landing-field [on Sand Spit], found while searching for possible killed or wounded soldiers. Two men were seen on rim of pit a short time before 11:09 a.m. explosion.”

“TA Dranga Sr. came across crater floor but said that Mr. Truman Taylor of Pahala, who was with him on the way up to crater, had left him 10 minutes before the explosion”

“Went back to find missing man with Clark, Dranga Jr. and Dranga Sr. Taylor was discovered with legs crushed by fallen bowlders about 125 feet from old parking place.”

“Dranga Sr. started to get car seat, to use as stretcher, when another explosion came. Dranga Jr. and I carried Taylor to road where he was put into car.” (USGS)

“Truman A Taylor, bookkeeper at Pahala, died at 11:30 o’clock last night [May 18, 1924] at Hilo Hospital from hemorrhage and shock. One leg had been amputated at the ankle after it had been crushed by a shower of rocks from the volcano.”

“Taylor was found shortly before noon yesterday by an unidentified man who heard screams. He was covered by burning ash, and both legs were crushed.”

“First aid was given by Capt PK McKenzie, surgeon at Kilauea Military Camp and the injured man was rushed in Army ambulance, accompanied by Miss Molly Thomas, Hilo nurse, to Hilo Hospital.”

“Taylor was from Chicago, and had been in Pahala about two months, after a stay of three weeks in Honolulu. He wore a tag bearing the legend, ‘USA 3422044.’” (SB, May 19, 1924)

Whose Footprints Are These?

Geologic evidence suggests that the modern caldera of Kīlauea formed shortly before 1500 AD. Repeated small collapses may have affected parts of the caldera floor, possibly as late as 1790. For over 300-400 years, the caldera was below the water table.

Kilauea can be an explosive volcano; several phreatic eruptions have occurred in the past 1,200 years. (Phreatic eruptions, also called phreatic explosions, occur when magma heats ground or surface water.)

The extreme temperature of the magma (from 932 to 2,138 °F) causes near-instantaneous evaporation to steam, resulting in an explosion of steam, water, ash and rock – the 1980 eruption of Mount St. Helens was a phreatic eruption.

The 1924 eruption at Halemaʻumaʻu documents and illustrates the explosive nature of Kilauea. However, the 1924 explosions were small by geologic standards and by the standards of some past Kilauea explosions.

The hazards of larger explosions, such as those that took place multiple times between about AD 1500 and 1790, are far worse than those associated with the 1924 series. (USGS)

There were explosions in 1790, the most lethal known eruption of any volcano in the present United States. The 1790 explosions, however, simply culminated (or at least occurred near the end of) a 300-year period of frequent explosions, some quite powerful. (USGS)

Keonehelelei is the name given by Hawaiians to the explosive eruption of Kilauea in 1790. It is probably so named “the falling sands” because the eruption involved an explosion of hot gas, ash and sand that rained down across the Kaʻu Desert. The character of the eruption was likely distinct enough to warrant a special name. (Moniz-Nakamura)

At the time, Kaʻū Chief Keōuakūʻahuʻula (Keōua) was the only remaining rival of Kamehameha the Great for control of the Island of Hawaiʻi; Keōua ruled half of Hāmākua and all of Puna and Kaʻū Districts. They were passing through the Kilauea area at the time of the eruption. The 1790 explosion led to the death of one-third of the warrior party of Keōua. (Moniz-Nakamura)

Camped in Hilo, Keōua learned of an invasion of his home district of Kaʻū by warriors of Kamehameha. To reach Kaʻū from Hilo, Keōua had a choice of two routes one was the usually traveled coastal route, at sea level, but it was longer, hot, shadeless and without potable water for long distances. (NPS)

The other route was shorter, but passed over the summit and through the lee of Kilauea volcano, an area sacred to, and the home of, the Hawaiian volcano goddess Pele. Keōua chose the volcano route, perhaps because it was shorter and quicker, with water available frequently. (NPS)

In 1919, Ruy Finch, a geologist at the Hawaiian Volcano Observatory discovered human footprints fossilized in the Kaʻū desert ash. Soon, this area of the desert became known as “Footprints.”

Barefoot walkers left thousands of footprints in wet volcanic ash within a few miles southwest of Kīlauea’s summit.

Many historians and Hawaiians believe the footprints were made by Keōua and his warriors. Keōua was known to be in the area at the time, and previous thought suggested this part of the desert did not have pre-contact use, so it was narrowed down to them.

Scientists later investigated – one approach was to look deeper at the evidence.

Forensic studies indicate that the length of a human foot is about 15% of an individual’s height. A man’s foot may be slightly more that 15%, a woman’s slightly less, but it is possible to estimate the height to a couple of inches. (USGS)

They measured 405-footprints to determine how tall the walkers were. The average calculated height is only 4-feet 11-inches, and few footprints were made by people 5-feet 9-inches or more tall. Early Europeans described Hawaiian warriors as tall; one missionary estimated an average height of 5-feet 10-inches. Many now believe that most of the footprints were made by women and children, not by men, much less warriors. (USGS)

Meanwhile, Keōua’s party was camped on the upwind side of Kīlauea’s summit – perhaps on Steaming Flat – waiting for Pele’s anger to subside. They saw the sky clear after the ash eruption and began walking southwestward between today’s Volcano Observatory and Nāmakanipaio. (USGS)

Suddenly, the most powerful part of the eruption began, developing a high column and sending surges at hurricane velocities across the path of the doomed group. Later, survivors and rescuers made no footprints in the once wet ash, which had dried. (USGS)

Then, archaeologists looked for other evidence to help identify who the footprints may have belonged to. Contrary to general thought that the area was not used by the Hawaiians, archaeological investigations discovered structures, trails and historic artifacts in the area. (Moniz-Nakamura)

Most of the features were along the edge of the Keʻāmoku lava flow. Several of the trails converge south of the flow, suggesting a major transportation network. The structures are likely temporary, used as people were traversing through the desert on their way to/from Kaʻū and Hilo. (Moniz-Nakamura)

The sheer number of temporary shelters along the Keʻāmoku flow, as well as the trail systems and quarry sites, strongly suggest that this area was frequently used by Hawaiians travelling to and through the area – before and after the 1790 eruption. (Moniz-Nakamura)

If the footprints aren’t Keōua’s warriors, then how did one-third of his warriors die?

Several suggestions have been made: suffocation due to ash; lava, stones, ash and other volcanic material; or strong winds produced by the eruption, asphyxiation and burning killed them. (Moniz-Nakamura)

A more recent suggestion is that a “hot base surge, composed primarily of superheated steam … (traveling at) hurricane velocity” was the cause of death. The wind velocity prevented the people from running away; they probably huddled together, then “hot gases seared their lungs.” (Moniz-Nakamura)

Some now suggest that, if these observations and ideas are correct, the footprints were made in 1790, but not by members of Keōua’s group. (USGS)

A reconstruction of events suggests that wet ash, containing small pellets, fell early in the eruption, blown southwestward into areas where family groups, mainly women and children, were chipping glass from old pāhoehoe. They probably sought shelter while the ash was falling. Once the air cleared, they slogged across the muddy ash, leaving footprints in the 1-inch thick deposit. (USGS)

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 Kilauea and Mauna Loa on Hawaiʻi and Haleakalā on Maui.

Eventually, Kilauea Caldera was added to the park, followed by the forests of Mauna Loa, the Kaʻū Desert, the rain forest of Olaʻa and the Kalapana archaeological area of the Puna/Kaʻū Historic District.

In 1961, Hawaiʻi National Park’s units were separated and re-designated as Haleakalā National Park and Hawaii Volcanoes National Park.) (Lots of good information here is from USGS, NPS and Jade Moniz-Nakamura.)

Kenichi Maehara

“After 20 years of service as clerk in the Hilo post office, K Maehara will retire to private life at the end of this month. He is leaving the postal service on account of impaired eyesight and will devote his entire attention to the management of the Camera Craft Shop at Kamehameha Ave.” (Star Bulleting, May 21,1921)

Born in Japan on April 2, 1880, Kenichi (also Kenzo) Maehara was a prominent Hawaiian photographer who owned the Camera Craft Shop in Hilo. He also held the photography concession in the Hawai‘i National Park (now known as the Hawai‘i Volcanoes National Park.

He built and operated the Volcano Photo Studio adjacent to the on-site hotel, the Volcano House, near what is today’s Kīlauea Visitor Center. (He also operated an “up-to-date portrait studio” in the Osorio building in Hilo.

Maehara specialized in developing, printing, enlarging, coloring, and framing pictures, photographs, and lantern slides of park and island scenes. He also sold postcards, some from photographs taken by others.

Maehara came to Hawai‘i from Hiroshima, Japan in 1896 and over his 30-year career grew to become a renowned and respected local businessman whose photos of volcanic eruptions were published and distributed around the world.

He photographed the Kilauea 1924 eruption; then, Mauna Loa (“Long Mountain”) began erupting at 6:20 pm on November 21, 1935.

Lava flows from Mauna Loa were generally fast-moving and voluminous. Lava moved relentlessly at a rate of five-miles each day; it pooled up between Mauna Kea and Mauna Loa at about where the Saddle Road is situated.

The ponded lava eventually began to follow the lay of the land, a natural drainage … Then, things “got interesting.” Lava was heading directly toward Hilo. (USGS)

Dr. Thomas A Jaggar Jr, the government volcanologist, estimated that the flow would reach Hilo by January 9, 1936. He suggested using dynamite to collapse lava tubes near the source of the flow in order to stop or divert it.

Explosives were first suggested as a means to divert lava flows threatening Hilo during the eruption of 1881. However, Jaggar’s plan of mule teams hiking the explosives up the mountain would take far too long – the lava flows were moving a mile a day.

It was suggested to use US Army Air Corps bombers to precisely deliver explosives. Jaggar agreed, and the call was made. The US Army Air Corps approved, and the mission and plans to strategically bomb Mauna Loa were set into motion.

Maehara took photos of the lava bombing on request from the director of the Hawaiian Volcano Observatory. Ironically the same photos that were commissioned by the US government.

As it turned out, after the Japanese military attack on Pearl Harbor on December 7, 1941, Maehara was arrested and detained under suspicion of disloyalty to the United States. Evidence used against him included photos he took of the 1935 US military bombing of a Mauna Loa lava flow.

Because of this and his participation in the local Japanese community, Maehara was declared a security threat. Army intelligence officers discovered a significant amount of cash at his premises as well as a large number of pornographic pictures, which, apparently, he had sold regularly to visiting soldiers. (Chapman)

Maehara was sent to detention facilities in Honolulu, and he was later transferred to an internment camp in the state of New Mexico.

Shortly thereafter, the newspaper reported, “The permit of K Maehara to operate a photographic concession in the Kilauea section was cancelled December 31 and will not be renewed. Mr Maehara, a Japanese alien, is interned by the authorities.” (Star Bulletin, August 12, 1942)

With the photography concession canceled on December 31, 1941, the Park’s chief clerk deposited the former concessioner’s cash; NPS employees removed his equipment to a vacant park residence, and boarded up the concession building for the time being. (Chapman)

In 1943, while he was still interned, Maehara’s Volcano Photo Studio was demolished. He would never return to the national park in an official capacity.

He returned to the Islands. In 1950, Kenichi and his wife Matsue Maehara changed their names to Yokoyama (Honolulu Advertiser Sep 25, 1950) Daughter Masako Yokoyama received her PhD from Yale in 1949; she married Floyd G Lounsbury and joined her husband teaching at Yale. (Lots here is from NPS.)

1960 Kapoho Eruption

The eruption in Kilauea Iki had ended on December 21, but the shallow reservoir beneath the summit of Kilauea volcano was gorged with magma. Rather than removing pressure, the eruption had, for all intents and purposes, created more.

The end of 1959 was an uneasy time for the staff at the Hawaiian Volcano Observatory. During the last week of the year, a swarm of earthquakes started in Pāhoa (more than 1,000 earthquakes were recorded by the Pāhoa station on January 12.)

The 1960 Kapoho eruption and its predecessor, the 1959 summit eruption in Kilauea Iki Crater, together formed a summit-flank sequence. The Kapoho eruption caused havoc in lower Puna, an idyllic rural community until the lava fountains and flows covered farm land and villages.

The size and frequency of the earthquakes increased; at 8 am, January 13, the ground was severely cracked along the fault through Kapoho town. Movement along the fault was literally pulling the town apart.

The ground was constantly shaking. The roughly 300-residents undertook voluntary evacuation, which was completed by early evening. At 7:35 pm, January 13, 1960, a red glow above Kapoho confirmed the start of the eruption.

Within half an hour, fountaining was nearly continuous along a nearly ½ – mile long fissure. After a couple hours, the activity focused with central fountains – for the next 11-hours powerful steam blasts roared from the vents.

The resulting fallout coated everything with a thin film of fine, wet, glassy ash. Salt crystals formed as the water evaporated; they testified to the brackish nature of the groundwater.

By noon on January 14, the steam blasts had ended and lava fountaining was confined to many sources along a 650-foot long section of the fissure. An ʻaʻa flow, 18-feet thick and nearly 1,000-feet wide reached the ocean – a bench formed 300-feet beyond the old shoreline.

In an attempt to save Warm Springs, bulldozers pushed a rock dike; shortly after, lava overtopped it and filled the pool.

Kapoho, a bit uphill of the fissure, was near all this activity but had not been touched by lava. Pumice and lava were wreaking havoc on nearby homes and farms (papaya, coconut, orchid and coffee groves.)

ʻAʻa continued to enter the ocean; it was also spreading southward. Bulldozers worked in forming a barrier to protect Kapoho, Kapoho School, an area of expensive homes and real estate at Kapoho Beach Lots. By January 20, lava had reached the barrier and overtopped it on January 23; a second barrier was shoved aside on January 27.

A third barrier held the flow, but lava then moved underground, beneath the end of the barrier, emerging near Kapoho School. The buildings began to burn at 10 am and the school was lost shortly after noon.

The barrier itself remained intact, and it survived until February 5, when it was finally overtopped and almost totally buried by lava that eventually covered the Kapoho cemetery. More coastal houses were lost.

Despite notable developments in the vent area, Kapoho village remained virtually intact except for a blanket of pumice and ash that covered everything.

For seven hours on the afternoon of January 27, the heaviest pumice fall of the entire eruption rained down on the area during strong kona winds.

However, it was the lava flow that would doom the town.

Late that night, the rapidly moving ʻaʻa flow moved through the streets, overwhelmed building after building. By midnight January 27, most of Kapoho had been destroyed; a couple days later (January 30) the town was gone.

The eruption ended slowly. Dribbles of lava continued to enter the sea north of Cape Kumukahi as late as February 13. High fountains continued until February 15, when lava was spraying upward from the main vent area to heights of 600-feet. It gradually subsided and on the morning of February 19, the eruption stopped.

Volcanologists concluded that the Kapoho eruption was tied to events at Kilauea’s distant summit. On January 17, four days after the Kapoho eruption had started, the summit began to subside (deflate, by analogy with a balloon) as magma was leaving the storage reservoir and heading down the east rift zone to the Kapoho area.

The eruption was the first during the modern era of volcano monitoring at Hawaiʻi Volcanoes Observatory. As a result, probably more fundamental ideas were reached from it than from any other single eruption in Hawaiʻi.

The main lesson, and really the only one that bears repeating over and over again, is clear. What happened then will happen again. That lesson should never be lost. (All information here is from USGS.)

Three Volcano Pioneers of the Mid-19th Century Hawaii

“Keep and publish careful records, invite the whole world of science to co-operate, and interest the business man.” (Jaggar)

The efficiency of an institution which is essentially educational and not commercial, productive of ideas rather than dollars, must be measured by its effect on productive men of learning in stimulating them to production; that is, to new discovery, experiment investigation and publication.

The founding of the Volcano Observatory and the formation of the group of subscribers here called the “Research Association,” were themselves evolved productions of the inspiring work of early investigators, as well as of the natural intellectual stimulus created in man by the unexplained Kilauea lake of boiling nebulous flux.

Three names stand out above all others as recorders of the work of the Fire Goddess in Hawaii in the middle decades of the nineteenth century : Titus Coan, James Dwight Dana, and William Lowthian Green.

Coan the missionary, earnest seeker after truth, for more than a third of the century watched every detail of the evolution of the volcanoes, pondered their meaning, and moreover made truthful record in scores of letters which were promptly published.

This genius for recording is rare among men, and is an all-important requirement in science; many men are good observers, but millions of valuable observations are forever lost, because of a lack of appreciation of the value of a jotting down – day, hour, minute, event, stages, appearances.

All science is no more than a categoric jotting-down, and the grouping of facts into new categories, until some of these reach the dignity of “theory.”

Coan without apparatus or endowment was an institution, a first Hawaiian volcano observatory, and in actual output he was a better observer and recorder than some institutions which have been elaborately equipped.

Professor Dana of Yale, foremost American geologist, was with the Wilkes Expedition at Kilauea in 1840, revisited Hawaii later, and wrote in 1891 a book, “Characteristics of Volcanoes,” which stands preeminent among volcano memoirs.

It was inspired by Kilauea and Mauna Loa, but is broad and sane, and presents a most painstaking and thoughtful summary of the progress of Hawaiian volcanic events, and their bearing on geology. Dana published in New Haven Coan’s letters, and it was doubtless Dana who stimulated much of Coan’s recording.

Green, the man of business, in his leisure moments student of volcanic life and of the inspiring heights and depths of the globe, conceived: to scale, with its film of waters and its blanket of gas, wrote a remarkable book in two volumes, “Vestiges of the Molten Globe.”

His second volume deals especially with the volcanoes, which he visited many times, and of it Professor Daly of Harvard writes: “It is certainly a pity that the second part of Green’s work is not more generally known. The book is almost as remarkable a contribution to the philosophy of vulcanism as Part 1, ‘On the Tetrahedral Theory of the Earth,’ is important in cosmogonic philosophy.”

Green’s work foreshadowed theoretic conceptions which modem thought has fixed more firmly, and his interest, as a business man, in the affairs of pure science was forerunner of the wider interest of many business men (and intelligent women) of Hawaii who now make up the Hawaiian Volcano Research Association.

These three men, Coan and Green resident here, Dana from an eastern university, typify the reason for the creation of an Hawaiian Volcano Observatory, and their portraits should forever hang in honored place upon its walls.

Coan, the systematic observer, showed the value of record and system; Green, the merchant, fascinated by the spell of Pele and inspired by the problems of position of this mid-Pacific pinnacle, Hawaii, rising 37,000 feet above the ocean deep, adopted volcanology for avocation, and left monumental work to inspire specialist and layman alike.

While Dana the scholar, coming from a distant seat of learning, hospitably entertained in the islands by Coan, Green, Bishop, Brigham, Alexander and a host of kind friends, rewarded their kindness by making famous to the whole world the achievements of his Hawaiian scientific colleagues.

Dana added new volcano lore and illustrated what production may come from scientific hospitality. (All here is copied from Special Bulleting of Hawaiian Volcano Observatory, 1913, as stated by Thomas Jaggar.)
