Collapse of the Pu'u 'O 'o Crater Floor on March 5, 2011
Video showing the collapse of the Pu'u 'O 'o crater floor on March 5. The video starts at 4 am and ends at 11 pm. The floor of the crater dropped about 115 meters (377 ft) in just a few hours.

2-Day Draining of Halema`uma`u
This Quicktime movie shows a sequence taken from a thermal camera looking into the Halema‘uma‘u vent cavity between March 5 and 7. Tremor and deflation began at about 1:42pm on March 5, and this was shortly followed by draining of the Halema‘uma‘u lava lake.

Fissure Eruption Between Pu'u 'O 'o and Napau Crater
Video clip shot from the air looking SW at the fissure eruption between Pu'u 'O 'o and Napau Crater. The fissure segment in the tephra in the foreground opened seconds earlier, and only about 10 minutes after the eruption as a whole started. The cracks through the tephra are in the process of opening, though this can't be picked out at this distance.
