Time-Lapse Summary of Two Years of Halema‘uma‘u Activity
Kilauea volcano in Hawaii has been erupting nearly continuously since 1983. This Quicktime movie shows exactly two years of lava lake activity in Kīlauea's Halema‘uma‘u 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 Halema‘uma‘u. 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.Today, activity continues within the lava lake and elsewhere at Kīlauea. Visit the Hawaiian Volcano Observatory website to view regularly posted images of the activity and read the daily updates about the status of the ongoing eruption.
