Kīlauea summit subsides and produces frequent earthquakes

On June 23, 2018 at 4:32 p.m. HST after approximately 17 hours of elevated seismicity, a collapse explosion occurred at the summit if Kīlauea. The energy released by the event was equivalent to a magnitude 5.3 earthquake. During the intense shaking, rockfalls cascaded down the northern margin of the caldera wall just below Uēkahuna Bluff sending rock dust into the air.
