Time-Lapse Summary of Two Years of Halemaʻumaʻu Activity Kīlauea volcano in Hawaiʻi has been erupting nearly continuously since 1983. This Quicktime movie shows exactly two years of lava lake activity in Kīlauea's Halemaʻumaʻu Crater (Feb 11, 2011 to Feb 11, 2013) in one minute of time-lapse video, using images taken from a thermal camera perched on the rim of Halemaʻumaʻu. Click the video to the right to watch as the lava level rises and falls with pressure changes in the magma system, and the vent widens as the walls collapse into the lava lake.
