# Active lava pond deep with the Halemaumau vent cavity

## Detailed Description

movie shows the active lava pond deep within the Halemaumau vent cavity. The lava is upwelling at the northern margin of the pond (the upper margin in this view), and slowly migrating south towards the bottom of the image, where it sinks out of view. The pond is about 50 m wide. Small spattering sources appear and disappear occasionally. This video was taken with a thermal camera (white is hot, dark blue is cold), which is able to see through the thick fume. No views were possible with the naked eye today due to the fume, and only loud gas roaring sounds could be heard.
