Lava lake level remains high, rockfall triggers explosive event
Detailed Description
A rockfall from the wall of Halema‘uma‘u Crater impacted the lava lake around 10:20 am, triggering an explosion of spatter and smaller particles. HVO geologists working on the far side of the crater captured the initial moments of the plume rising. The explosion deposited a large amount of spatter around the closed Halema‘uma‘u visitor overlook.
