Detailed Description

The lava lake's levee stands up to 8 m (26 ft) above the surrounding crater floor. This steep-sided levee impounds the lava and forms what is called a "perched" lava lake. Pieces of the rim occasionally collapse into the lake, leading to sudden and fast-moving overflows of lava onto the crater floor.
