Abstract
The tectonic deformations and seismic activites of 26 active boundary zones are studied based on the delineation and studies on active tectonic blocks in the continent of China, these 26 active boundary zones are located in 6 active tectonic block regions and 22 active tectonic blocks. The relationship of distribution of major earthquakes with active boundary zones, the relationship of tectonic movement rate with the level of seismic activities in boundary zones and the relationship of tectonic movement rate with recurrence periods of strong earthquakes in boundary zones, etc., are studied in the paper. The linear relation between tectonic movement rate and seismic activities and the reverse relation of tectonic movement rate and recurrence interval of strong earthquakes are presented. The results reveal the tectonic characteristics and motion characteristics of active tectonic blocks in the continent of China, and indicate that the activity of strong earthquakes is controlled by the tectonic deformation of block boundary zones.
