Detailed Description

Movie of the lava lake in KÄ«lauea's summit vent in Halema‘uma‘u crater minutes after a slice of the vent wall had plunged into the lava. The lava lake is roiling violently as the recently added wall debris is digested by the lava. Slabs of rock can be seen breaking loose from the base of the overhanging vent wall and falling into the lava. The length of time it takes the rocks to reach the lava surface provides an indication of the size of the hole-it's about 150 m (492 ft) across and the rocks are falling about 60 m (197 ft).
