Abstract

An early warning system that will predict volcanic eruptions weeks before they occur has been developed by Geotech. Seismometers and event counters are used to detect even very slight movements of the magma. Changes in the frequency of these microearthquakes can be recorded and analyzed, providing an early indication of increasing volcanic activity. The Geotech system includes 6 to 10 event counters and seismometers, a portable survey kit consisting of seismometers and magnetic tape recorders, and a base station of seismometers, amplifiers, tape recorder, visual recorder, and timing, power, and analysis systems.
