The space and time variations of seismic activity preceding Bihar 1988 (Mhave. 6.5) been and Manipur Burma. (M 6.8) border earthquakes of examined and compared with those of 1968 and 1978 (Himachal Pradesh) and 1966 and 1980 (Nepal West Uttar Pradesh Hills). It was found that the seismicity pattern preceding Manipur Burma border earthquake was broadly similar to that of the earthquakes of 1968, 1978 and 1980 in western Himalayas namely increase in seismicity followed by seismic quescence. However, the logarithm of the quiescent area was pattern not proportional to the magnitude of the impending earthquake. Such a of seismicity did not develop in the case of Bihar Nepal Earthquake earthquakes of 1988. However, increase in seismicity through the occurrence of of magnitude 2 less than that of the mainshock was noted.
