A seismic and pressure transducer system for monitoring velocities and impact pressures of snow avalanches

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...
