Earthquake focal mechanisms and seismotectonic deformation in the Kamchatka-Commander region

摘要: Abstract The system of stresses in the lithosphere (0–59 km) and upper asthenosphere (60–150 was analysed on basis focal-mechanism data for events M > 5.0 1964–1982. zoning made considering types faulting predominant stress systems. Four uniformly-stressed zones have been identified within two asthenosphere. deep distribution shows presence a double seismic focal zone under Kamchatka. Schemes seismotectonic-deformation (STD) rate-tensor components were dran separately lithospheric asthenospheric layers. To this end, individual averaged solutions regional moment-energy class relationships used. average STD rate is 10−9 yr−1, 10−10 yr−1. Vertical horizontal are same order.
