对常德太阳山断裂及其与地震关系的认识

UNDERSTANDING ABOUT THE TAIYANGSHAN FAULT IN CHANGDE CITY AND ITS RELATION TO EARTHQUAKE

太阳山断裂包括太阳出东侧断裂和太阳山西侧断裂。实际上,它们是一个北北东向的断裂带,具有规模大、长期活动的特点,与地震关系十分密切。1631年常德6.5级大地震,即发生在该断裂带上。该断裂带具备孕育中强震的地质构造条件,有再度发生中强震的可能性,建议加强地震监测。

Taiyangshan fault zone includes the east Taiyangshan fault and the west Taiyangshan fault.In fact, they form a NNE trend fault zone, broad in scale, characteristic of long-term activity, which is closely related to earthquake. A strong earthquake graded 6.5 on Richter scale had taken place in 1631 in this fault zone. This fault zone has provided with the geologic-tectonic conditions breeding middle to strong earthquake, and there is possibility that a middle to strong earthquake may take place again, so it is proposed that earthquake observation be enhanced.
