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.

Measuring how volcanoes move with satellites...
July 14, 1995

Last week we discussed the different land surveying techniques HVO scientists use to monitor the swelling and movement of active volcanoes.

The ground around an active volcano swells, deflates, or shifts as magma moves in and out of the volcano's underground plumbing system. The distribution and rate of ground deformation provides clues about processes occurring within the volcano.

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...

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.
