Estimates of Lithospheric Failure Cycle Parameters from Regional Earthquake Catalogues
International audience Based on the generalized frequency–magnitude relation for earthquakes, the failure cycle parameters are estimated from regional seismic catalogues for zones with different typical tectonic regimes: subduction zones and shear fault zones. The Kamchatka and Japan catalogues are...

International audience Based on the generalized frequency–magnitude relation for earthquakes, the failure cycle parameters are estimated from regional seismic catalogues for zones with different typical tectonic regimes: subduction zones and shear fault zones. The Kamchatka and Japan catalogues are used for the subduction zones. The estimates for the shear fault zones are based on the data for the San-Andreas Fault presented in the Northern California Earthquake Catalog, the data for the North Anatolian fault presented in the earthquake catalogue for Greece, and the data for the Zagros shear zone presented in the catalogue for Iran. Distribution maps are constructed for the failure cycle duration and for parameter q characterizing the dependence of the duration of the failure cycle on the size of the fractured area. It is shown that on average for each region, the q values are close to zero, indicating that the probability of failure for structural elements of the medium does not depend on their size and that the strength and stress distributions by size of inhomogeneities are, on average, consistent with each other. The intraregional spatial variations of parameter q exceed the statistical error of the estimates, which can be interpreted as evidence for the existence of variations in the distribution of stresses by size of inhomogeneities.
