| Summary: | Observation of volcanic earthquakes was continued on Mount Erebus, Antarctica, by maintaining 3 telemetering seismic stations installed in the 1980-1981 field season. Two telemetering stations were newly installed on the flank of Mount Erebus and on Mount Terror. Observation of magnetic induction loop and infrasound which might be associated with volcanic eruption was also continued at the summit of Mount Erebus. In order to reduce noises in the time signal, the recording-system clock at Scott Base was replaced by the electrically shielded time code generator. Five temporary seismic stations were installed on the flank of Mount Erebus after the maintenance of the telemetering system. Constitution of a densely located network of 7-8 stations with the aperture of 5-10km will enable us to obtain rather accurate hypocenter parameters of shallow earthquakes with 0-3km focal depth. |
