Recent activities at Kīlauea Volcano's Upper East Rift Zone have not led to an eruption, but there have been significant seismic activities and ground deformations. Within a 24-hour period, 15 earthquakes were recorded beneath the summit, and 99 in the Upper East Rift Zone, at shallow depths of 0 to 4 kilometers. Minor summit inflation was detected, but no significant inflation or deflation was noted in the Upper East Rift Zone. Sulfur dioxide emissions at the summit were measured at 65 tonnes per day. The middle and lower East Rift Zone and the Southwest Rift Zone showed low seismicity and ground deformation. Gas monitoring near Puʻuʻōʻō reported negligible sulfur dioxide emissions.
From July 22 to July 25, 2024, over 1,500 earthquakes, including 30 of magnitude 3 or greater, indicated magma intrusion between Pauahi Crater and Maunaulu, extending possibly to Makaopuhi crater. This phase has concluded, but the potential for further seismic swarms or intrusions remains. The USGS Hawaiian Volcano Observatory continues to monitor and provide updates. Hazards include ground fractures, subsidence, rockfalls, and elevated volcanic gases, posing risks to both landscapes and human safety. No imminent eruption signs are present, but vigilance and preparedness are essential due to the volcano's dynamic nature.
