Detailed Description

Sounds of lava lake activity within Kilauea Volcano's summit vent inside Halema`uma`u Crater on the afternoon of February 14, 2011. The continuous "crashing wave" noise is the sound of churning lava as gases are released from the lake surface, which is in nearly constant motion. The discontinuous sharp "pops" occur when rocks falling from the vent wall hit the lava lake surface. A very faint "clinkery" sound (like broken glass) was also produced by a small rock slide on the vent wall.
