Caldera Dynamics

Caption

Seismic clues show that before and during the eruption rock in the caldera moved along outward-sloping faults (black lines) as the volcano bulged and then collapsed. This type of fault had been suggested from models, but never before confirmed in this level of detail. Molten lava rose to the seafloor below the east rim of the caldera and then toward the north.
