    Abstract:

    This paper discusses the historical large earthquake reappearance pattern in its focal reigon of China. It has been Found that a number of the historical large earthquakel reappearances were distributed on the active tectonic zone in the western geosyncline of China. Most of the spatial locations earthquake in the focal region are repeated within the intensity Ⅷ area on the stretch reorientation of a main repture plane where the historical largest earthquake occurred. The empirical relationship between the magnitude of such earthquake reappearance in the magistoseismic area and the magnitude of the historical large shock is rectilinear as shown by the formulas (1) in the text. These can be used to determine the magnitude of the reappearance earthquake occurred in the magisto-seismic area.
    Most of the interval reappeared earthquakes are within……100 years. The relationship between the earthquake reappearance time and the regional active tectonic dimension and extent:is as follows the larger and more intensive the active tectonic dimension is the longer the interval reappeared historical large earthquake in the magistoseimic area will be.
    At last the characteristics mentioned above are physically explained and give a supplementary explanation of how to make use of them.
