#upper East Rift Zone

Seismic activity reported at Kīlauea’s upper East Rift Zone

The Hawaiian Volcano Observatory is reporting an “abrupt increase” in seismic activity recently in the upper East Rift Zone of Kīlauea.

Earthquakes rattle Kīlauea’s upper East Rift Zone

Increased earthquake activity and rates of ground deformation at Kīlauea’s upper East Rift Zone began at approximately 11 a.m. where about 40 earthquakes were detected, the largest of which was a magnitude-3.1.

Unrest continues beneath Kīlauea as number of quakes doubles during past day

There were about 50 quakes beneath the volcano’s summit and 100 under the upper East Rift Zone compared with 20 and 50 the day before.

Unrest escalates at Kīlauea; more than 500 earthquakes rock upper East Rift Zone

While there are no signs of an imminent eruption, the largest of these earthquakes were four magnitude-3.0 events near the intersection between Chain of Craters Road and Hilina Pali Road in Hawaiʻi Volcanoes National Park.

Activity up slightly with increase in quakes at Kīlauea

Seismicity remains above background levels. Ground deformation also continues beneath Halemaʻumaʻu and the south caldera region. Magma has been pressurizing the system beneath Halemaʻumaʻu and Kīlauea’s south caldera region for several weeks.
