USGS Radar Helps Monitor Redoubt Volcano, AK

Detailed Description

View of the north flank of Redoubt Volcano from the research hut where one of the webcams is situated. This zoomed image shows a minor block-and-ash flow advancing down the talus slope below the dome produced from hot debris shed off the dome. Hot debris collects in the gorge above the waterfall generating minor, secondary steam/ash clouds. AVO/USGS photo by Game McGimsey, April 30, 2009.
