Structure and Development Stages of Chuya Earthquake Aftershock Process, Mountain Altai

摘要

Space-time structure of Chuya earthquake aftershock process is detailed understood, based on a study with temporal station network. Spatial components of aftershock area, divided by vertical slack zones and confined to different blocks of the Earth s crust, are stand out: Chagan-Uzun block, Chuya depression angle and two blocks fit to Kurai depression. It is found that this depression in the aftershock field shows itself in the form of two elements. Two phases in aftershock process development have been established. The second phase starts by large aftershock 1.10.2003 01:03 (Ms=6.6). A new component in aftershock process structure is made, and behavior of aftershock area on the whole is changed.
