Abstract: A tectonophysical method for estimating seismic energy and efficiency from the data on tectonic features, geological media, physical environment and driving background is established on the basis of a simplified elliptical hypocenter model, which considers strong constraint from hypocentral surroundings and uniformization of sliding resistance, and the calculation of hypocentral parameters. The method is examined by means of calculations of data of 28 strong earthquakes with magnitudes greater than 6.0. The results show that the seismic efficiencies, η, ranges from 0.008 to 0.050 and deviation of the estimated magnitudes from those determined previously by conventional seismological methods is within ±0.5 for 78.6% of the earthquakes examined.
