Activities of Japanese earth science research in the McMurdo Sound region in the 1982-1983 season
Three Japanese scientists visited McMurdo Station from November 4,1982 to January 13,1983 to participate in the International Mt. Erebus Seismo-logical Studies (IMESS). This was the third year of the cooperation project among Japan, the United States and New Zealand. The members are K. KAMINUMA (Nat...

| Summary: | Three Japanese scientists visited McMurdo Station from November 4,1982 to January 13,1983 to participate in the International Mt. Erebus Seismo-logical Studies (IMESS). This was the third year of the cooperation project among Japan, the United States and New Zealand. The members are K. KAMINUMA (National Institute of Polar Research), S. UEKI (Faculty of Science, Tohoku University) and E. KOYAMA (Earthquake Research Institute, the University of Tokyo). Following research programs were carried out : 1) Seismic observation by the telemetry network; Japanese scientists played back the magnetic tapes which have been recorded since September 1982. The daily frequencies of volcanic earthquakes occurring in and around Mt. Erebus were counted and earthquakes were scaled. 2) Observations by a temporary seismic network; From November 15,1982 to January 4,1983,nine seismic temporary station were established on the flank of Mt. Erebus for determining the earthquake locations with high accurately. 3) Gravity measurements; LaCoste-Romberg gravimeter model G were used at nine temporary seismic stations. Twenty additional gravity stations were also established around the summit crater of Mt. Erebus. |
