Center for the Study of Active Volcanoes

On Kilauea, several aa flows meander along gentle slopes, then cascade down the steep pali. Clinker falls forward, exposing the hot molten interior of the flows; vegetation is buried. Footage shot in 2008 (private property) and in 1992 & 1993 (above Kamoamoa, in HVNP). Video shot & edited by UHH Center for the Study of Active Volcanoes (CSAV). Why does Hawaiian basalt sometimes produce pahoehoe flows, and other times aa? Please read this pdf article for details on the difference between aa and pahoehoe: http://pubs.usgs.gov/pp/pp1676/pp1676_05.pdf

CSAV is based at the University of Hawaii at Hilo. Since 1990, we have been providing educational and training programs about volcanoes and earthquakes. In the mid-1990's, we branched off and began educational programs about hurricanes, tsunamis, and other natural hazards as well.

Three UH-Hilo web sites (CSAV, Natural Hazards Hawaii, and Geology) have featured low-res photos and videos for years. We are currently rebuilding the videos in high-res, and as we do, they will appear on this channel. In addition, watch for periodic new videos of eruption conditions, tsunamis, and whatever else Mother Nature sends our way.

Current equipment: Sony DCR VX2100 Handycam & Sachtler tripod. Computer: Mac G5; editing with Final Cut Pro.
