20061343 Cui Xiaofeng (Institute of Crustal Dynamics, CEA, Beijing 100085, China); Xie Furen Regional Characteristics of Focal Mechanism Solutions in China and Its Adjacent Areas (Seismology and Geology, ISSN 0253-4967, CN 11-2192/P, 27(2), 2005, p.298-307, 6 illus. , 2 tables, 15 refs. )focal mechanism, China Based on analysis of distribution of 2 660 earthquake focal mechanism solutions from “Database of Crustal Stress of China and Adjacent Area” (updated to December, 2003), the regional characteristics of focal mechanism solutions are studied. In the Northeast and North China stress regions, the orientations of maximum horizontal stress mostly are in the near EW direction and NEE-SWW direction. The strike-slip focal mechanism is predominant in Northeast and North China stress regions. In the South China stress region, the predominant orientation of maximum horizontal stress is in NE-SW direction. The focal mechanisms mainly include thrust faulting and strike-slip faulting. In the Xinjiang stress region, the predominant orientation of maximum horizontal stress is in near N-S direction.
