Seismotectonic Model for 1966 Xingtai Earthquake Swarm——Nucleation of Newly Generated Fault or Friction Stick-slip Along a Preexisting Active Fault
摘要
Abstract
Shallow seismic profiling in meizoseismal area of Xingtai earthquakes, phase division of Cenozoic movement of deep and shallow structures, analysis of characteristics of crustal and upper mantle structure, and comparative study on parameters of seismic sources indicate that the listric faults controlling the development of early Tertiary basin-range structure and eastward gently-dipping detachment below it in the Xingtai epicentral area are not related to the occurrence of Xingtai earthquakes. The Xingtai earthquake swarm is a product of threedimensional fracture process in which the discontinuous "deep faults", separated by NWtrending faults or by transverse barriers, successively tore, fractured, and propagated upward and, hence, caused the stress between the adjacent deep faults to migrate and load under the action of latest tectonic stress field. The Xingtai seismogenic fault represents a "newly generated fault" resulted from the upward tearing and propagation of the preexisting crustal "deep fault".关键词
