Characteristics of Short-term Synthetical Anomalies of Radon and Mercury Content in Groundwater in Sichuan-Yunnan Region before Strong Earthquakes;

The Dynamic Evolution Characteristics of GL Value in Sichuan-Yunnan Region and Forecast of the Strong Earthquake;

Discrimination and regional features of medium-and short-term precursors ofground fluid in Sichuan-Yunnan region;

Numerical simulation of loading/unloading effect on Coulomb failure stress among strong earthquakes in Sichuan-Yunnan area;

Simultaneous inversion of small earthquake relocation and velocity structure in Sichuan-Yunnan area;

On the basis of the analysis of velocity field,deformation field and strain field of Sichuan-Yunnan area,we proposed the complex deformation model with coexistence of clockwise rotation around eastern Himalayan syntaxis,stretch,compress and shear deformation in Sichuan-Yunnan area.

0 ) in Sichuan Yunnan region and the numbers of the aftershocks, the rupture type of every group of earthquakes was determined according to the theory "a strong earthquake belongs to strike slip type or rupture type".

In this paper,the relation between strong earthquake activity and regional active faults,present motion states of active block and deep medium environment in Sichuan Yunnan region,had been analyzed.

5 earthquakes from 1971 to 2000 in the Sichuan and Yunnan regions to do a spatial scan analysis.

Through the space-time scanning for the earthquakes occurred in Sichuan and Yunnan regions during the past 30 years,the seismicity factors A-value and the space-concentrating degree C-value are calculated.

Distribution, characteristics and genesis of Mississippi Valley-Type lead-zinc deposits in Sichuan-Yunnan-Guizhou area;
