Halema'uma'u Explosive Eruption (October 14, 2008)

A sequence of collapses scattered over several hours on October 14, 2008, culminated in an explosive eruption that blasted lithic and juvenile tephra onto the Halema'uma'u crater rim 85 meters (280 feet) above the informally-named Overlook vent (see http://hvo.wr.usgs.gov/kilauea/timeline/ for links describing eruptive activity at the summit of Kilauea Volcano). The October 14 explosive eruption blasted lithic and juvenile tephra onto the Halema'uma'u crater rim 85 meters (280 feet) above the vent. Collapse of the western (upper left) side of the vent rim is visible through the fume 15-20 seconds before the ash emission starts.

The images that comprise this video were acquired by a webcam positioned on the rim of Halema'uma'u Crater about 85 meters (280 feet) above the Overlook vent. The image acquisition rate was 1 frame every 2 seconds, and the resulting video is played at 12 frames per second.
