Abstract

A new observation system of pyroclastic flow is based on spatio-temporal derivative method for occurrence-detection and spatial filtering method for velocity measurement by digital image processing of thermal infrared video images of the flow. Our system has been successful in observing the pyroclastic flow occurred at Mt. Unzen-Fugen.
