摘要
The focal mechanism solutions and the distribution characteristic of 88 moderate-strong earthquakes in Xinjiang and its adjacent area from 2003 to 2009 are analyzed.The result shows that stress field in Xinjiang area is mainly controlled by level pressure stress in NNW direction in this period,with certain difference from the principal compress stress P axis distribution in NNE from 1990 to 2002.The seismogenic faults of moderate-strong earthquakes exist certain multiplicity,it demonstrates the complexity of tectonic movement in Xinjiang area.
