Abstract

In the 1983-1984 field season volcanic earthquakes in and around Mount Erebus occurred at a rate of 20-60 events per day. The earthquakes in this season are located wide around Mount Erebus. The clustered earthquakes have a dike-like distribution beneath the N area of the central zone. An aseismic zone is recognized beneath the SW area of the Erebus summit. This aseismic zone may correspond to a magma reservoir. The earthquakes which were not associated with the eruptions of Mount Erebus can be divided into several types according to their seismograms and spectra of the seismic waves. The seismic waves which may pass through the aseismic zone seem to be strongly attenuated as compared with those which may not pass through the zone. -from Current Antarctic Literature
