A detailed 3-D P-wave velocity model of the crust and uppermost mantle under the capital region is de- termined with a spatial resolution of 25 km in the horizontal direction and 4—17 km in depth. We used 48750 preci...
The proxy of U37 index is widely applied to K ’ reconstructing paleotemperature in the marine environment. However, the long-chain alkenones (LCAs) research is rarely reported in the liminic system. In this paper, we...

The sub-regions are divided for the seismicity of the Chinese mainland based on the hypothesis of the active crustal blocks and the division of the active boundaries. On this result, the seismicity of each active crus...
A 6-year long GPS observation (1998—2003) indicates that crustal deformation in the Three Gorges area is less active at a marginally measurable rate of 0—5 mm/a relative to stable South China block. However, the imp...
In this paper, the earthquake hazard parameters (λ m,b and M max) from the maximum likelihood method for the raw catalogue and declustered catalogues have been used to discuss the effect of the aftershocks on the ear...
