SEISMOLOGICAL BULLETIN OF SYOWA STATION, ANTARCTICA, 2006.

The article highlights the seismic observations made at the Syowa Station in Antarctica in 2006. The observations were maintained throughout the season of the 47th Japanese Research Expedition (JARE-47). The two types of seismometers that have been used for the seismic observations were the short-period seismometer (HES) and the three-component broadband seismometer with digital recording system. The digitization of the three-component analogue outputs by HES was done by sampling frequency by a 24-bit analog-to-digital (A/D) converter, generation of triggered signals of 80 and 1 hertz and 20 hertz continuous output.
