Vigorously bubbling lava surface beneath Halema`uma`u vent

Movie shows a roiling, bubbling lava surface approximately 100 yards beneath the rim of the vent within Halema`uma`u. This is the first clear view of lava within the vent, which opened on March 19, 2008. The video was taken from a helicopter hovering over the Halema`uma`u overlook area. The overhanging rim at the right side of the frame is the floor of Halema`uma`u crater.
