Increased seismic activity under Kilauea volcano, Hawaii

Over the past three weeks, Kilauea volcano in Hawaii has exhibited increased seismic activity, with fluctuations in shallow and deep earthquakes at the summit. The Hawaiian Volcano Observatory reports sustained low sulfur dioxide emissions and continuous monitoring due to this heightened state of unrest.

Increased earthquake activity and signs of magma movement beneath Kīlauea’s summit, detected on January 31, 2024, have prompted the USGS Hawaiian Volcano Observatory to elevate the volcano’s alert level from ADVISORY/YELLOW to WATCH/ORANGE. With over 500 earthquakes recorded since midnight and ground deformation indicating pressurized magma chambers, the risk of an eruption remains high.
