December 2, 2022 — Mauna Loa Lava Bomb
Detailed Description
Spatter bomb from fissure 3 of Mauna Loa's Northeast Rift Zone eruption. The bomb was molten and plastic when it fell to the ground. As it flew through the air, the molten lava stretched and started to break apart as it was cooling. As this bomb came to rest on the round it continued to cool and solidify with these stretched morphologies. USGS image by D. Downs.
