The inducing earthquake conditions such as the seismicity, stress state,karst and permeability of rock in the reservoir are analyzed , and the maximum magnitude and .

The inducing earthquake conditions of the Qiaoqi and Zhonggang Reservoir are comprehensively analyzed according to the field investigation, and it is compared with other reservoir.

Mechanism of reservoir-induced earthquake and earthquake resistant fortification;

Prediction of the reservoir induced earthquakes in the Ertan Hydropower Station;

So it is necessary to establish the database of Danjiangkou reservoir induced seismicity which will be applied to the prediction of seismicity,the quakeproof and redu.

So estimating the magnitude of reservoir induced seismicity is profound to the quakeproof and reducing disaster of reservoir area.

A brief introduction of fundamental and applied researches in the field of seismology engaged by the seismological division under KNMI has been given in the paper, the researches are focused on infrasound, induced earthquakes, mining law and the projects in the European centre for exchange and coordination of seismological data (ORFEUS) hosted by the seismological division.

The prediction ability of induced earthquakes is tested from statistical simulation.

The induced earthquakes happened near the well, the magnitudes of these earthquakes are small, the earthquake sources are shallow, and they belong to the main shock after shocktype or the swarmtype earthquakes, but not belong to the solitary type earthquakes.
