Detailed Description
Spatter and "ribbon bombs" (stretched fragments of molten lava) up to 30 cm (about 12 inches) long fell to the ground surface on the rim of Halema‘uma‘u Crater during the two most recent explosions from Kīlauea's summit lava lake. The black, glassy lava fragment shown here, about the size of a standard donut, landed amidst smaller, solid pieces of rock blasted from the vent.
