Waiwelawela


Paʻu o keahi o Waiwelawela o ka lua e
Aloha na poʻe la o

The pit of Waiwelawela is encircled by fire
Greetings to the people of the upland pit

(From the chant “A popoʻi haki kaikoʻo” – it describes how Pele got established in Puna; it compares the movement of the lava to the movement of water.)

There are indications that the ancient Hawaiians made use of natural hot springs for recreation and therapy. Oral history relates that the ancient chieftain, Kumukahi, frequented hot springs in Puna to relieve his aches and pains.  (Woodruff/Takahashi)

“The fame of the waters of the warm springs of the Puna districts has been great during many years. In fact, it is a legend … that when the ailments of the body overcame the aliʻi of old they betook themselves to the spring known as Waiwelawela … and there they were healed of rheumatic affections through bathing, and their systemic ills cured by drinking of the waters.”

“This legend has come down to the Hawaiians of today and even now there is a fame attached to the waters of the springs, which draws to the side of the stream scores of the native residents of nearby districts.” (Pacific Commercial Advertiser, January 28, 1902)

Waiwelawela “is a warm spring, crescent shaped, and of a vivid ultramarine in color …. The spring, named the Blue Lake, is 90-deg in temperature and 900-feet above the level of the sea.  The water is wonderfully clear and, strange to relate, at this elevation, it has a regular rise and fall which is said to correspond to the tide of the ocean.”  (Daily Bulletin, August 28, 1882)

The Kapoho Warm Springs was formed when the downthrown block of the Kapoho fault slipped below the water table and exposed the warm waters, probably heated by a magmatic body intruded in 1840.  (USGS)

“At present no practical use is made of them, but were there a proper access a small hotel would be built and many invalids would be able to make use of these springs.”  (Hawaiian Gazette, September 17, 1889)

“The famous warm spring is to be found near the residence of Mr RA Lyman (Kapoho’s largest landowner) and is one of the finest bathing places on the islands.  Natives formerly flocked to the place from all over the islands believing that it was possessed of great healing powers.”

“The water is a pleasant temperature for bathing and is clear as crystal, small objects can be readily distinguished twenty feet below the surface. There is a mineral taste to the water.”  (Pacific Commercial Advertiser, March 22, 1892)

“The railway now goes so close to them that it is believed if a few cottages were built, and attendance provided, many afflicted people would be glad to go there and be healed.  Even those who need no physician would find at these springs a place for rest and contemplation, far from the maddening crowd.”  (Pacific Commercial Advertiser, October 12, 1908)

“It is the most marvelously beautiful place in all these beautiful islands. There is not a doubt of it. The pool, at the base of a small peak that is like what Diamond Head would be if that had sugar cane growing to its very summit, lies shaded by a dense growth of ʻōhiʻa and koa and lehua trees and guava bushes, the sun glistening upon it through the leaves of these.”

“The waters, not steaming, but of perceptibly higher temperature than the air, by some strange law of refraction are shot through with dazzling gleams of a blue that is like the blue depths of the sky. Yet the rocks in the pool are not blue. They are of rather reddish cast.”  (Mid-Pacific Magazine, 1912)

“The exposed basin where the spring comes to the surface is something like five by six yards, and the water rises from no one knows where and departs no one sees how.  The water is warm and is very full of mineral salts.”  (Pacific Commercial Advertiser, January 28, 1902)

“This spot is unquestionably one of the loveliest in all Hawaiʻi, and its charm is typical of Hawaiʻi.  It is close against the face of a volcanic cliff.  Here there is a shady grotto, and in this grotto a pool almost as it hewed out of the rocks for the bathing place of some giant of the forest.”

“The water is in spots 20-feet deep, but so translucent that it seems much less than 10.  It holds many lights and shadows, many hues and colors, varying from the deep indigo blue to a transparent jade-green and in spots a golden brown.  There are seats here and the shade is grateful.”  (Honolulu Star-bulletin, September 6, 1916)

At Warm Springs, where portions of ‘Bird of Paradise’ (1951) and other motion pictures had been filmed, stone steps led to a spring-fed, naturally heated pool fringed by ferns, cattleya orchids and lau hala trees.

The grounds and a half-mile drive were landscaped with plumeria, thousands of ti plants, crotons and ginger. Picnic tables and barbecue pits dotted a smooth lawn shaded by mango trees.  Slim Holt, who leased the property from Lyman, had labored for years to create this beauty, assisted by interested individuals and organizations.  (Flanders)

Then, “Something was amiss.”  An eruption at Kilauea had ended on December 21, 1959.

“(B)ut the shallow reservoir beneath the summit of Kilauea volcano was gorged with magma, far more than before the eruption started. Rather than removing pressure, the eruption had, for all intents and purposes, created more.”

“The uncertainty ended at 1935 January 13, (1960,) when red glow in the night sky above Kapoho announced the 1960 eruption.”  (USGS)

Bulldozers erected a quarter-mile line of dikes designed to prevent the lava from reaching Warm Springs.  Despite this effort, toward midnight the flow surmounted the embankments.

Barbecue pits exploded; trees, shrubbery, tables and benches burst into flame. Lava poured down stone steps in a cherry-red stream.  Still water, reflecting the infernal scene, disappeared under the flow. The new cinder cone was dubbed Puʻu Laimanu.  … Today, buried beneath this primeval landscape, under 50-feet of lava, lays Warm Springs.  (Flanders)

“Estimates of damage from the six-day eruption of Kilauea volcano rose into the millions today.  State Senator Richard F Lyman estimated damage to his land, blanketed by the lava as $2,000,000.”

“He owns 80-acres of sugar land and the Warm Springs resort area, now buried by the flow on Hawaiʻi Island.  Other landowners reported 3,500-acres of farmland destroyed.”  (The Spokesman, January 20, 1960)

“Waiwelawela (meaning ‘warm water’) was a warm spring pool near Kapoho which was covered in the 1960 eruption. … It is said by people of the area that Pele covered the springs because people were charging others, namely Hawaiians, for use of the warm springs. In former days these warm springs were available to everyone.”  (Pukui; DOE)

Bombing the River of Fire


Like most Hawaiian eruptions, the eruptive activity was immediately preceded by a swarm of earthquakes, followed by tremor.  Mauna Loa (“Long Mountain”) began erupting at 6:20 pm on November 21, 1935.

The eruption started with a curtain of fountains near North Pit within the summit caldera, Mokuʻāweoweo. The vents migrated 2-miles down the northeast rift zone.

During the six days of the main event, fissures opened up along the northeast rift zone of the mountain, fountaining lava 200- to 300-feet into the air.

On November 26, the summit eruption died and the northeast rift activity was reduced to a single vent at the 11,400-foot elevation.  A small vent also opened up further below on the north flank of the mountain at the 8,600-foot elevation.  (USGS)

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.

Guido Giacometti, a friend of Jaggar, had suggested using 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. Lieutenant Colonel George Smith Patton was called on to oversee the Army operation.  (He’s the same Patton who would go on to WWII fame.)

Lava tubes are cooled and hardened outer crusts of lava which provide insulation for the faster-flowing, molten rock inside. Such a conduit enables lava to move faster and farther.

The theory was bombs would destroy the lava tubes, robbing lava of an easy transport channel and exposing more of the lava to the air, slowing and cooling it further.  (BBC)

On December 26, 1935, six Keystone B-3A bombers of the 23d Bomb Squadron and four Keystone LB-6A light bombers from the 72d Bomb Squadron joined the rendezvous circle in the predawn darkness off Diamond Head, and then headed to Hilo.

Jaggar briefed the crews on the methods he had in mind to divert the lava flow. He then flew over the volcano to assess the flows and select the right points for bombing.

8:30 am, December 27, 1935, the first five bombers departed on the bombing mission.  (A second flight of five aircraft was planned for the afternoon.)  Each plane carried two 300-pound practice bombs (for practice and sighting,) as well as two 600-pound Mk I demolition bombs (355 pounds of TNT each.)

The bombers opened formation and fell into a huge circle for a follow-the-leader dummy run over the target area.  They were flying at about 12,500-feet, not far above the 8,600-foot altitude of the volcano’s flows.

As the lead pilot tipped the control column forward for his run he lowered the wheels, so that by the time he neared the clump of koa trees which served as reference point his plane would be moving only a little faster than the 65-mph landing speed.

‘OK?’ he called to his bombardier as they began their climb after passing over the flow. Standard radio-voice procedure was unneeded. … ‘OK,’ the bombardier grunted.  (Johnson)

Five of the twenty bombs struck molten lava directly, most of the others impacted solidified lava along the flow channel margins; one of them turned out a dud.

“Colonel William C Capp, a pilot who bombed the lower target, reported direct hits on the channel, observing a sheet of red, molten rock that was thrown up to about 200′ elevation and that flying debris made small holes in his lower wing.”

“Bombs that impacted on solidified, vesicular pāhoehoe along the flow margin produced craters averaging 6.7-m diameters and 2.0-m depth….”  (Swopes)

“Pilots observed that several bombs collapsed thin lava tube roofs, although in no case was sufficient roof material imploded into the tube to cause blockage.”

Jagger wrote that “the violent release of lava, of gas and of hydrostatic pressures at the source robbed the lower flow of its substance, and of its heat.”

The lava stopped flowing on January 2, 1936.  The effectiveness of the lava bombing is disputed by some volcanologist.  (USGS)

Here’s a link to a video of the Army bombing runs in 1935.  (Lots of information here from Army, USGS, hawaii-gov, 4GFC, Johnson, Lockwood & Torgerson, Swopes and This Day in Aviation History.)

Kilauea Iki Eruption - 1959


Visitors to Hawaiʻi Volcanoes National Park and its “Devastation Trail” may not know how/when that devastation happened.

The eruption of Kilauea Iki in November 1959 turned once lush fern forest into a ‘wasteland’ of lava and cinder.

Now, a walkway allows you to walk through the devastation.

During the eruption, fountains of molten lava shot up as high as 1,900-feet tall from the eruptive rifts – 3 times the height of the Washington Monument.

Pumice buried the lush forest, which is preserved on the eastern side of Devastation Trail.  On the west side of the trail is the sterile, moon-like devastation surface of pumice.

The eruption deposited and piled up the pumice and cinders into a large mound.

A few ōhi‘a trees, dead and bleached, poke up through the pumice and very gradually some ōhi’a, ōhelo and ferns are beginning to recolonize the dead zone (unfortunately, some blackberry, too.)

While the images of the eruption are spectacular, to really “feel” the power you need to hear the raw force of Hawaiʻi’s volcanoes.

Unfortunately, these old photos/videos do not have audio linked to them.

When we were kids, living on O‘ahu, whenever the eruption happened, we’d go to the Big Island to see it, including the 1959 eruption of Kilauea Iki.

Primal Force is the name on a Kilauea eruption.  It’s that and memorable.

Here are a couple an old video clips of the 1959 Kilauea Iki eruption I found on YouTube …  no audio.
