DEVELOPMENT OF MONGOLIAN SEISMIC NETWORK AND INTERNATIONAL MONITORING SYSTEM STATIONS

Abstract

First seismic station of Mongolia installed in 1957 with assistance from the Soviet Union and it was using photo paper for recording seismic data. Since the first station installation time, Mongolian seismic network expanded with a number of the seismic stations and developed the technological improvement. Institute of Astronomy and Geophysics (IAG) operates four types of IMS stations including seismic, infrasound, radionuclide and noble gas stations (PS25, IS34, MNP45, and MNX45) now. Mongolian National Data Centre (MNDC) receives seismic and infrasound data including IMS data using different communication technologies in real and near real-time from stations all around Mongolia including IMS stations. Current status of the CTBTO IMS stations in Mongolia and some radionuclide analysis results of the Mongolian IMS noble gas station (MNX45) will be presented.
