摘要:
通过研究华南西部地区近期发生的5级以上地震,梳理中强地震前定点形变观测资料出现的异常特征,分析形变曲线异常变化特征与华南西部地区中强地震的关系。结果表明:趋势变化异常对华南西部地区5级以上地震的发生有一定的指示意义,当区域内出现与自然环境和观测环境无关的趋势变化异常超过3个月,异常台站300km范围内存在发生5级左右地震的可能。研究得到的认识对华南西部地区地震前兆异常识别以及地震趋势研究有积极的意义。
Abstract:
Based on the study of recent earthquakes with M≥5 in western South China, this paper sorts out the anomalies characteristics of fixed-point deformation observation data before moderately strong earthquakes, and analyzes the relationship between the abnormal variation characteristics of deformation curve and moderate-strong earthquakes in western South China. The results show that: The trend change anomaly has a certain indication significance for the occurrence of earthquakes with M≥5 in western South China. When there is a trend change anomaly unrelated to the natural environment and observation environment in the region for more than 3 months, there is a possibility of an earthquake of about M5 within 300 km of the abnormal station. The understanding obtained in this paper is of positive significance to the recognition of earthquake precursor anomalies and the study of earthquake trend in western South China.
