The source characteristics of 33 earthquakes with magnitude mb between 4.4 and 6.0, which occurred in the Himalayan and nearby regions, are investigated using the records of the Hyderabad seismograph station. The P- and S-wave spectra of these events are interpreted in terms of Brune's seismic source model for estimating the source parameters, i.e., seismic moment, source dimension, stress drop, average dislocation, apparent stress and the radiated energy. Seismic moments, M0, vary between 0.3 × 1024 and 9.0 × 1026 dyne cm; source dimensions, r, between 4.3 and 18.6 km; stress-drops, Δσ between 0.3 and 151.6 bar; average dislocations, u between 0.6 and 381 cm; apparent stresses, ησ between 0.1 and 73.2 bar. The radiated energy, ER is estimated by the spectrum integration method and is found to vary between 0.2 × 1018 and 9.3 × 1022 erg. In general, the stress drop and apparent stress are found to be high, indicating high stresses in these regions.
