Thermal View of Active Lava Pond within

This movie shows the active lava pond within PuuOo crater, imaged with a thermal camera. The video is shown at x60 speed, and covers about 25 minutes. Lava is being supplied to the crater from two vents, one visible in the upper right corner of the image and one out of view in the lower left. Crustal foundering events, in which a section of the thin surface crust ruptures and sinks, exposing the hot interior of the pond, are common. This view is towards the north.
