Activity within PuuOo

This movie shows video taken during today's field visit and overflight. The first portion of the video is taken at the rim of PuuOo crater, and shows the north vent feeding the lava pond. The lava surface undulates due to rising gas bubbles, and a small overturn is triggered. The second portion of the video shows an open stream of lava at the summit of one of the rootless shields on the Quarry flow.
