The United States Geological Survey (USGS) warned on Sunday morning the Hawaii volcano summit collapsed after being hit by 40 earthquakes an hour.

The resulting summit explosion was likened to a magnitude 5.3 earthquake at the volcano’s crater.

The USGS said: “At 6.52pm HST on June 22, after approximately 25 hours of elevated seismicity, a collapse explosion occurred at the summit producing an ash-poor steam plume that rose 500 ft above the ground surface, 4,500 ft above sea level, before drifting to the southwest.
