Under the coordination and supervision of the National Institute of Polar Research, a 3-man Japanese party installed on Mt. Erebus three permanent seismological networks with radio telemetry links to Scott Base in cooperation with the U. S. and New Zealand parties during the 1980-81 field season. The Japanese party also installed a temporary seismological network of six seismometers around the main crater. The summit station also telemeters data from two acoustic channels which were used to monitor explosions in the crater and to monitor the flux of electrically charged gases with an experimental induction loop. A preliminary study showed that the seismic activity of Mt. Erebus was exceedingly high, namely, many micro-or ultramicro-shocks have occurred and their time sequence was swarms.
