Seismogenic Width of a Fault Zone

摘要

High-precision catalogues containing data on the spatial distribution of earthquake sources associated with several fault zones have been processed. The analysis shows a high degree of spatial localization of seismicity. Most of the events are observed in a narrow zone with a characteristic width of about 100 m. This value is a part of a percent of the fault zone length and corresponds to the upper boundary of estimates concerning the effective fault width, which are made on the basis of data on the characteristic parameters of roughness and waviness of rock discontinuities.
