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.

Kīlauea fissure 8 lava channel transports "lava boats"

Geologists captured this time-lapse video of the perched lava channel issuing from fissure 8 on Kīlauea's lower East Rift Zone.

Rafts of accreted lava move down stream and look like boats moving down a river. These are termed lava balls or lava boats and form when portions of the fissure 8 cone or levees break away and are rafted down stream. As they move along
