Unified Interior Regions

Hawaii

The Pacific Region has nine USGS Science Centers in California, Nevada, and Hawaii. The Regional Office, headquartered in Sacramento, provides Center oversight and support, facilitates internal and external collaborations, and works to further USGS strategic science directions.

Video of lava flows

Same flow as in upper video, but a little farther upstream. Grass burns along the side of the stream. Width of view, 4-5 m.

January 17, 2003

Rushing toe of lava

Rushing toe of lava that has just broken out from front of one active lobe of flow on coastal flat seaward of Paliuli. Toe is about 50 cm wide. Note how crust is "scrunched" at bottom of minicascade, resulting in wrinkles. Other videos on this day show breakouts in same area. In all videos, wind noise may be bothersome.

January 17, 2003

Small gush of lava

Small gush is on crest of small divide and starts flowing down right side as well as left. Stream is about 1 m wide.

January 17, 2003

Lava tear

Tear begins to develop in crust on stage-left side of flow. Lava eventually pours from tear. Stream is 0.75-1 m wide.

January 17, 2003

Wrinkling of thin crust

Video shows wrinkling of thin crust at bottom of gentle slope. Note the concave-upstream shape of the wrinkles. Stream is about 1 m wide.

January 17, 2003

Lava runs from under crust along edge of inflating flow

Lava runs from under crust along edge of inflating flow. Flakes of crust, heated by the emerging lava, spall off and fall onto surface of lava. Width of view, about 75 cm.

January 17, 2003

Two streams break from under inflating flow

Two streams break from under inflating flow. Note how crust forms on closer stream and becomes wrinkled where lava runs into barrier. Each stream is about 3 m long.

January 17, 2003

Slow moving lava

Lava slowly rafts plate of crust downstream. Width of plate of crust, about 1 m.

January 14, 2003

Rapidly flowing single toe of lava

Rapidly flowing single toe of lava at front of flow 440 m seaward of Paliuli. Other videos on this day focus on similar toes. Sound was turned off during the imaging. For scale, flowing lava in all clips is 1-3 m wide.

January 14, 2003

Sheet of lava pouring from inflating flow

Sheet of lava pouring from inflating flow. Note wrinkling, moving crust.

January 14, 2003

Lava pouring from inflating flow

Same sheet of lava pouring from inflating flow but seen from different angle.

Single toe in action

Single toe in action. Note concentric wrinkes forming at bottom of view.

Hawaii is a land of rugged beauty and untamed natural forces swathed in a beguiling gentleness that is unmatched anywhere else on Earth.

The formation of new islands invariably sparks the imagination. On June 6th a submarine eruption began at Metis Shoal in the Tonga Islands. A passing ship confirmed that an eruption was continuing on June 9th.

On Monday and Tuesday of this past week, large waves generated by a storm near New Zealand caused considerable damage on the west coast of Hawai'i, particularly in the town of Kailua

Hawaii is seismically very active. During a typical month, there are invariably several earthquakes that are large enough to be felt. This past month was no exception, as there were nine earthquakes having magnitude greater than 3.0.

The eruption along Kīlauea's East Rift Zone continues with little change. Lava from two vents on the south and west sides of the Pu'u 'O'o cone is transported underground through a lava tube to the ocean about six-and-a-half miles to the southeast. No lava can be seen at either of the active vents.
 

Lava flow hazard map revisited...
May 28, 1995

Maps showing volcanic hazard zones for the Big Island were first prepared in 1974 by the U.S. Geological Survey.

The main function of the U.S. Geological Survey's Hawaiian Volcano Observatory is to reduce the risk from volcanic activity.

The current eruption along Kīlauea's East Rift Zone continues with passive effusion of lava. The lava is transported underground to the coast along the western edge of the flow field, where it enters the ocean after cascading over an ancient sea cliff.

Sitting at lunch on Wednesday, many residents of the island of Hawaii might have thought that someone or something had kicked their chairs. Of course, they were feeling the ground shaking generated by the sequence of small earthquakes beneath the south flank of Kīlauea Volcano that was reported in other news stories.
 

Kīlauea lava flow status as of April 30, 1995...
April 30, 1995

The 12-year-long eruption on Kīlauea's east rift zone continues, with vents on the southwestern flank of the Pu`u `O`o cone feeding directly into lava tubes. These tubes form within active lava flows and initially are very shallow.

A team of volcanologists from the U.S. Geological Survey has been monitoring an eruption that began just after midnight on April 3 on Fogo in the Cape Verde Islands off the west coast of Africa.

Hotspots...
April 14, 1995

Many of the islands that dot the center of the Pacific Ocean are made up of active, dormant, or extinct volcanoes, whose geologic histories are characteristic of "hot spot" volcanism.
