#Kilauea East Rift Zone
Update: Episode 12 of Kīlauea eruption ends after 22 hours
Episode 12 of the Halemaʻumaʻu eruption of Kīlauea within Hawaiʻi Volcanoes National Park ended at 10:37 a.m. HST on March 5 after just under 22 hours of continuous eruptive activity. Fountaining from the south vent ceased at 10:35 a.m. at the same time summit deflation changed to inflation and tremor decreased. Current hazards include volcanic gas emissions and windblown volcanic glass (Pele’s Hair) that may impact Hawai’i Volcanoes National Park and nearby communities.

It was a dark and stormy night… and the volcano had a secret.
Volcano Alert Level raised then lowered after brief rise in earthquake activity at Kīlauea’s upper East Rift Zone
Earthquake and ground deformation rates in Kīlauea’s upper East Rift Zone decreased significantly following a “burst of intense activity” at approximately 3:30 a.m. HST on July 23, 2024. Accordingly, the USGS Hawaiian Volcano Observatory has lowered the Volcano Alert Level for ground-based hazards from WATCH to ADVISORY and the Aviation Color Code from ORANGE to YELLOW.
Volcano Watch: A decade later, remembering the Pāhoa lava flow crisis
Over the past few years, eruptions of Kīlauea volcano on the Island of Hawai‘i have happened in remote regions and lava flows have not directly threatened communities. However, the approaching anniversary of a lava flow crisis a decade ago reminds us that eruptions on Kīlauea have the potential to cause damage and island-wide disruption.
Volcano Watch: What’s That (Seismic) Noise?
The USGS Hawaiian Volcano Observatory uses dozens of seismometers to locate individual earthquakes and identify signals that are related to faulting and magma movement within our volcanoes.
STUDY: Measuring Magma Viscosity Early Could Forecast Volcanic Eruptions
A team of researchers, including University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology Professor Bruce Houghton, identified an indicator of magma viscosity that can be measured before an eruption, providing critical information to help understand possible future eruptions.
