Kīlauea Volcano — Fissure 8 Lava Flow

Fissure 8 and the upper lava channel, viewed from the early morning helicopter overflight of the lower East Rift Zone. Recent heavy rains have soaked into the still-warm tephra and the moisture rises as steam (right side of lava channel).

Kīlauea Volcano — Evolution of a Blocked Channel (Part 1)

Evolution of a blocked channel, photo 1. A blockage of rafted material within the lava channel causes lava to flow over its banks near the Kapoho cone. In this section of the lava channel a cold lava flow from the 1960 eruption forms a barrier on the north side, which initially directed the channel to the southeast. A constriction in the channel formed at the bend where

Why do some earthquakes have negative depths?...
January 25, 2018

Astute visitors to the USGS Hawaiian Volcano Observatory (HVO) website may have noticed that some recent earthquakes have negative depths. This does not indicate a change in seismicity but, rather, an upgrade in HVO's seismic data processing system.

"During the current lapse in appropriations U.S. volcano observatories including the Hawaiian Volcano Observatory will continue to monitor volcanic activity and issue updates, warnings, and notifications through the usual channels, including this website, email, and news releases."

Lava erupting from the active vent on the east flank of Pu‘u ‘Ō‘ō has not entered the ocean or reached the Kamokuna lava delta during the past month. Instead, small lava flows are scattered across the 61g flow field, breaking out from the lava-tube network between Pu‘u ‘Ō‘ō and the coastal plain.
