Kilauea Volcano is rumbling. 

Since Thursday, the volcano’s upper East Rift Zone has been experiencing a swarm of earthquakes, according to an update from the U.S. Geological Survey. The intensity of the seismic activity increased Saturday night, with 350 earthquakes over 24 hours. The largest earthquake during this period was a magnitude-3.0 that occurred just north of Hiʻiaka crate at a depth of 2 miles. 

Since then, the earthquake rate has declined and shifted slightly toward the summit. On Monday morning, a magnitude-3.4 earthquake struck in the area between Keanakākoʻi and Koʻokoʻolau Craters. 

Increases in seismicity could result in an eruption, but there are no signs of an imminent eruption, according to the USGS. 

Kilauea last erupted on June 3, 2024, for about eight hours, southwest of the summit region.  

Following this eruption, magma has been repressurizing the storage system beneath Halemaʻumaʻu and the south caldera region, causing the aforementioned earthquakes.
