Hot! Hawaiian Volcano Is Amazing

This incredible view of a vent in the Halemaumau Crater within the Kilauea volcanic caldera on the Island of Hawaii was captured by a U.S. Geological Survey thermal video camera June 1.

Sped up by four times, the video reveals activity in the 450 foot-wide vent that is usually obscured by accompanying gas fumes. The cracks in the lava pond at the beginning of the video — when the lava is at a high stand in the vent — are just visible in the photo below.
