Kīlauea Volcano — Ocean Entry

Lava is entering the sea on the southern side of the entry area primarily through the open channel, but also along a 1 km (0.6 mi) wide area. The entry areas are marked by billowing laze plumes. The interaction of lava with the ocean creates "laze", a corrosive seawater

Kīlauea Volcano — Lava Flows from Fissure 8

View to the southwest, looking "up" the lava channel. Lava flows from Fissure 8 (not pictured) through the open channel about 13 km (8 mi) to the ocean. Lava remains incandescent (glowing orange) along the entire length of the channel with sections of cooled lava (black) on the surface. The dark areas in the lower portion of the image are parts of the early lava flow from

Kīlauea Volcano — Roadway Crack Observations

USGS field crews track activity in and around Leilani Estates in Kīlauea Volcano's lower East Rift Zone. Observations are also collected on a daily basis from cracks in the area of Highway 130, shown here (no changes in temperature, crack width, or gas emissions have been noted recently).

Kīlauea summit subsides and produces frequent earthquakes

On June 23, 2018 at 4:32 p.m. HST after approximately 17 hours of elevated seismicity, a collapse explosion occurred at the summit if Kīlauea. The energy released by the event was equivalent to a magnitude 5.3 earthquake. During the intense shaking, rockfalls cascaded down the northern margin of the caldera wall just below Uēkahuna Bluff sending rock dust into the air.

Kīlauea fissure 8 lava channel transports "lava boats"

Geologists captured this time-lapse video of the perched lava channel issuing from fissure 8 on Kīlauea's lower East Rift Zone.

Rafts of accreted lava move down stream and look like boats moving down a river. These are termed lava balls or lava boats and form when portions of the fissure 8 cone or levees break away and are rafted down stream. As they move along

With funding from USGS data rescue initiatives, HVO scanned seismograms from a number of significant earthquakes and seismic sequences. Since last summer, volunteer Marcy Frenz has enthusiastically and diligently assumed scanning duties at HVO, working through the 1974–1984 interval spanning Mauna Loa Volcano's two most recent eruptions.

A healthy coral reef at Buck Island, U.S. Virgin Island
April 20, 2017

In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai’i, U.S. Geological Survey researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion.

Volcanic explosions provide the foundation for agriculture...
March 23, 2017

The ash deposits on the southeastern part of the Island of Hawai‘i have fortuitously presented an agricultural opportunity in an otherwise rocky and hilly landscape. An underappreciated fact is that the explosive nature of our volcanoes provided this opportunity.
