Detailed Description

Booming sounds from the vent in Halema'uma'u have been audible around the summit area of Kilauea for the past several days. Some of these sounds are caused by rocks striking the surface of the lava lake, but most are actually the sound of the vent walls cracking due to heating and expansion of rock. This video, from February 25, illustrates what this sounds like. Occasionally, these sharp reports and booms can be visually correlated to rocks exploding off the vent wall and showering fragments down onto the surface of the lava lake.
