Abstract:

Successful prediction of a M 45 earthquake in 2009 in Anda suggested that abnormal variation of H2 concentration combined with geological background and other anomalies may become a means of earthquake forecast. In this work, we studied the blockstructured basement, the MesozoicCenozoic faults, and the deep upwelling asthenosphere as the structural background of earthquakes in Heilongjiang Province, using geophysical data of different depths. The relationship of the fault distribution with the earthquake distribution for recent years has been analyzed, soil gasconcentration data were collected in part areas and certain inherent correlation with faults was identified. Features of the seismic activities in the concerned area different from those in the western China are also related to the features of the fault activities here that can be interpreted by the fact  that the eastern ChineseMongolian region is creeping eastwards as shown by the GPS vector field.

Key words:  earthquake prediction, concentration of H2, fault activity; , block structure
