With the analysis of gravity/geomagnetic observation and cross-fault leveling data in the middle segment of Shaowu-Heyuan fault zone,the characteristic of the gravitational/geomagnetic field and crustal deformation field are discussed.

Heyuan fault and the selection for the location of Xinfengjiang bridge;

Study on fractal characteristic of hydrographic nets and activity of the Red River Fault Zone;

The Red River Fault Zone is a gigantic sliding fault zone beginning from the east of Qinzang plateau in the north to the northwest of Yunnan, and passing through the north of Vietnam, and then extending to South China Sea, the whole length is over 1000km.

The Red River Fault Zone is a large slide and active fault zone.

Geophysical research on deep structure feature in study region of red river fault zone;

We used double difference location method to relocate the moderate-small earthquakes on the Red River fault zone of Yunnan from 1999 to 2003, and analyzed the relationship of relocation result and geologic structure.

The Red River Fault Zone is a strike-slip zone along which Indochina Block was extruded during India-Tibet collision.

As a middle section of Tanlu fracture zone,Shuhe fracture zone intersects Wulian Qingdao tectonic zone in eastern part of Shandong, which makes up of an image of a reverse “ 入type" .
