Development of seismological observation in Mongolia

The Mongolian Seismological Observatory was established in 1957 - the International Year of Geophysics - with an analog seismic station (SKM-3) on the foundation of our center (Research Center of Astronomy and Geophysics of Mongolian Academy of Sciences - RCAG,MAS). The same year, the 4 December 1957, the strong Gobi-Altay earthquake occured (Mw=8.1). It confirmed the high seismic activity (three other events with Mw >= 8 occured the 1905/07/9, the 1905/07/23 and the 1931/08/10) and the hazard associated with it in Mongolia despite this high activity, associated with India-Asia collision, seems to be abnormally high during the XX century.
