摘要：

通过对2009年安达M 45级地震成功的预报,进一步认识到将H2浓度的异常变化与断层背景研究结合,并配合区域其他异常的检测可以作为地震预报的一种手段。结合不同深度的地球物理资料,讨论了黑龙江省的断块构造、中新生代断裂以及深部软流圈上涌的构造背景。将近年来地震分布、局部收集的土壤气体浓度资料与断层相结合,展示它们的内在联系。同时还引入GPS水平矢量显示中蒙东部构造区块现今向东的伸展蠕散运动的研究成果,用此解释研究区断裂活动的特征,并且指出这有别于中国西部地区地震活动的特征。

关键词: 地震预报, H2浓度, 断裂活动, 断块构造

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
