The New Seismographic Vault and the Detection Capability of Syowa Station, Antarctica (Reports of the Japanese Antarctic Research Expedition)
A new vault for seismographs was built at Japanese Antarctic Station Syowa (SYO) and the observation of the HES and the Long-Period seismographs started on March 1, 1970. The old seismograph room was not adequate for detecting the extreme micro-seismic activities when the wind velocity exceeded 10m/...
