Although detecting hot spots in the imagery is key, Ramsey takes his efforts a step farther and uses ASTERs multispectral information to study the chemistry of volcanic domes. A fire brigade member of the agricultural training station, several hundred meters away from the "fixed point", assumed incorrectly that the roaring of the pyroclastic flow was caused by a debris flow instead, and was engulfed by the pyroclastic surge when he left the training station to check the Mizunashi River. kilometers of ejecta.
