USGS Multimedia Gallery: (Video)--Lava Within Halema'uma'u Vent Cavity

Title: Lava Within Halema'uma'u Vent Cavity

Description:

This movie shows lava within the Halema'uma'u vent cavity, at a depth of about 200 m below the vent rim. The lava surface, which is about 20 m wide, is extremely vigorous, with constant roiling and semi-continuous spattering. Spatter deposited on the walls around the lava surface creates a hot, unstable surface, which can be seen to disintegrate as large blocks break off and fall into the lava.
