# Entire floor of the Halemaumau vent

## Detailed Description

movie shows video collected with a thermal camera during two helicopter overflights of the Halemaumau vent. The high vantage point allowed a view of the entire floor of the vent cavity, which is not possible from the ground. Also, the thermal camera can "see" through the thick fume that normally obscures the vent to the naked eye. The first half of the video shows observations on January 7, when a dome fountain on the floor of the vent cavity was feeding a wide, vigorously flowing lava stream towards the north. The second half of the video shows observations on January 13, at which point the lava stream had disappeared and two degassing holes were active. The northern hole (on the right) appears to have lava just below the rim.
