To have unifonnity with the available data on past earthquakes in a region, it is necessary that the local lDSj!J1itudes estiJruited from strong-motion accelerograms match with the published magnitude values based on the records of conventional seismographs. For this purpose, the magnitude estimates based on strong-motion data need an empirical correction to account for the anelastic attenuation of seismic waves recorded on conventional seismographs at large distances and for the saturation of strongmotion amplitudes during very large magnitude earthquakes. Such correction factors available for other parts of the world would not be, in general, suitable for earthquakes in the Himalayan region. Therefore, using available strong-motion data base from six earthquakes, appropriate oorrection factors are developed to calibrate the method of compoting local magnitudes from strong-motion “””elerograms in the Himalayan region.
