摘要

The Southeast China epi-continental arc is the latest tectonics affecting widespread near sea areas of the eastern China continent. Earthquakes related to the arc may be named epi-continental arc type ones which can be distinguished from island arc type and rift valley type earthquakes. Earthquakes in eastern China in the 20th century, especially in 1990s, are all caused by movement on the Southeast China epi-continental arc. Thrust-type foci occurred along the frontal arc whereas strike- slip type ones appeared along the both flanks. Intense earthquakes happened in the " collision" segment of the frontal arc as well as the flank segment cutting across the rigid basement. The region involved in the epi-continental arc has entered its seventh active period of this century.
