Kīlauea Volcano — Ocean Entry

View of the ocean entry (lower left) from this morning's overflight. Lava was entering the ocean across a broad area primarily on the north part of the lava delta. Upslope along the northern margin of the flow field, lava is still oozing from several points in the area of Kapoho Beach Lots. Fissure 8

Kīlauea Volcano — Channel Overflow

A small overflow from the lava channel (left side of image) captured by an Unmanned Aircraft System (UAS). Small overflows on both sides of the channel occurred shortly after midnight in the uppermost part of channel. None of these overflows extended past the existing flow field.

Kīlauea Volcano — Kapoho Coastline Ocean Entries

Lava continues to enter the sea along the southern Kapoho coastline. Lava enters the ocean primarily through an open channel, but also along a 1-km (0.6 mi) wide area. Also visible in the image (center right) is an area at the northern margin of the flow field that is oozing fresh lava at several points in the area of Kapoho Beach Lots.

Kīlauea Volcano — Remobilized Ash Plume

Recent explosive events haven't produced significant ash plumes from the summit, but downwind communities may still experience ashfall when previously erupted ash is remobilized. On authorized permission from Hawai‘i Volcanoes National Park, our Unmanned Aircraft Systems crew is conducting gas measurements at Pu‘u ‘Ō‘ō. They snapped this photograph from Chain of Craters

May 9, 2017

USGS scientists hiked to the summit of Mauna Loa, where they checked on HVO's monitoring instruments and realigned an antenna that allows webcam images of the volcano's summit caldera (shown in this panoramic image) to be posted on the HVO website.

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.
