Seismological observations by a three-component boadband digital seismograph at Syowa Station, Antarctica
A three-component broadband STS (Streckeisen seismometer) seismograph was installed at Syowa Station in 1989,to obtain precise (digital) seismic record for the study of the earth's interior and earthquakes. The STS observation system at Syowa Station is introduced and some examples of digital s...
