Preliminary Research on the Sequence Characteristic of the Short-Impending Medium Strong Foreshocks before Strong Earthquake in Yunnan Region;

There is significant relation between main shock locatiion and the linked line be-tween maximum foreshock location(point A)and secondry(point B).

Stage property and quasi-synchronization of anomalies development before earthquake are a main basis for earthquake prediction and tracing different types of anomalies, grasping seismogenic process and siezing th.
