Brief Description (Abstract):

A Seismological Station (code named MAIT) equipped with a matched 3-component short period digital and a short period vertical analog seismographs was commissioned at Maitri, the Indian Antarctica base station. The station became operational from 26th Jan, 1998. A noise survey for selecting a suitable site and feasibility study with the aim of operation of Broad-band seismographs at the station was carried out earlier during the Antarctica summer, in Jan-Feb, 1997. The normal background noise due to artificial and natural sources was found to be very low. However, a very high level of noise was observed due to heavy winds during the blizzards which rage the icy continent quite often. A thermally insulated vault has been specifically designed and buried underground as the Broad-Band seismographs are very sensitive to temperature and pressure variations. The vault has been further provided with an electronic device which maintains inside temperature at 15?0.5 ?C.

Status: Completed

Purpose: The objective of installation of a permanent state-of-theart digital Broad-band seismological station at Maitri, the Indian Antarctica base station, a reconnaissance for feasibility and site selection was carried out during the XVIth Indian Scientific Expedition to Antarctica in Jan-Feb, 1997. The aim of the station is to monitor earthquakes in and around Antarctica, the region with very low level of seismic activity, and overall monitoring of teleseismic events. This station would be specifically useful in the epicentral locations in the Indian Ocean, south of Asia and Africa, Presently only a three component short period digital Seismic system has been commissioned. A short period vertical analog seismograph is also being operated simultaneously.
