摘要
对鲜水河断裂带10多年的磁力观测资料进行处理。分析认为:鲜水河断裂带对网区磁力的时间变化有明显的控制作用:东南段的变化大于西北段,年磁场异常是地震的前兆。
The observation data of mobile geo-magnetism along Xianshuihe faults for 10 years are analyzed.The two dimensions chart of geo-magnetism field change is mapped.The faults of Xianshuihe control the changes of geo-magnetism field.The geo-magnetism field changes in southeastern parts of Xianshuihe faults are bigger than that in the southeastern faults.Some of geo-magnetism changes are related to the seismic events.
