Source parameters and scaling relations for small earthquakes in Kumaon Himalaya, India
We investigate the scaling relationships among earthquake source parameters using more
than 300 good quality broad band seismograms from 30 small earthquakes in the Kumaon
Himalaya from the spectral analysis of P and S waves. The average ratio of P/S wave corner
frequency is found to be 1.13, which is suggestive of shift in the corner frequency. The
estimated seismic moment range from 1.6× 10 13–5.8× 10 15 N m, while the stress drop
varies from 0.6 to 16 bars with 80% of the events below 10 bars. An analysis of stress drop …
