Brief Description (Abstract):

A new seismological station (code named M A I T) equipped with matched 3- component short period digital and a vertical short period analogue seismographs has been 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 subsequently was carried out during the Antarctica summer, in Jan-Feb, 1997. While the normal background noise due to artificial and natural sources was found to be very low, a very high level of noise was observed due to heavy winds during the blizzards which rage the icy continent very often. A thermally insulated vault has been specifically designed and buried underground as the Broad-Band seismographs are very sensitive to the temperature and pressure variations.

Status: Completed

Purpose: With the objective of installation of a permanent state-of-the-art digital Broadband seismological station at Maitri, the Indian Antarctica base station, a reconnaissance for site selection and a feasibility study was carried out during the XVI Indian Scientific Expedition to Antarctica in Jan-Feb, 1997. The aim of the station is to monitor earthquakes in and around Antarctic continent, the region with very low level of seismic activity, if any, and mainly monitoring of global distant teleseismic earthquakes. This station would be specifically useful in the locations of hypocentres in the Indian Ocean, south of Asia and South America and southern and Central Africa.
