ICEQUAKES RECORDED AT SYOWA STATION, ANTARCTICA
Icequakes have been recorded by a three-component seismograph of short period at Syowa Station (69°S, 39°E), Antarctica since seismic observations were started in 1966. The icequakes are roughly classified into two groups from their waveforms : a high frequency type and a low frequency type. Icequak...
