Abstract
An avalanche was monitored with seismic geophones placed in its track and impact forces were measured using pressure transducers. Preliminary results indicate that geophones may provide an inexpensive and reliable method of detecting avalanche events. Signals from these sensors can be used to start recording equipment. Correlations between the seismic and pressure signals enable approximate velocities within an avalanche to be estimated. The pressure signals are analyzed and the characteristics of the avalanche discussed.
