四川地区的地震定点地球物理观测状况研究

Research on the Status of Fixed-Point Geophysical Observation of Earthquakes in Sichuan Area

摘要: 地球物理观测是地震预测预报的基础技术支撑，只有对地球内部的变化情况进行严密的监测，产出精确的观测资料，对地震的预测预报才更具有可能性。为进一步加强四川的地震监测，为地震预测预报提供更加可靠的、更高精度的观测资料，本文系统梳理了四川地区的地震定点地球物理观测情况，为四川地区地震观测十四五规划提供参考。结果表明，四川的地震定点地球物理观测已有一定规模，存在以下特点：(1) 观测手段全，测项多；(2) 观测资料质量高，具有一定的映震能力；(3) 观测仪器类型多，同类型观测具有一定的可比性；(4) 观测台站分布不均匀；(5) 观测环境复杂，要进一步加强观测环境保护。

Abstract: Geophysical observation is the basic technical support for earthquake prediction. Only by closely monitoring the changes in the earth’s interior and producing accurate observation data, and it is more likely to predict earthquakes. In order to further strengthen the earthquake monitoring in Sichuan Province and provide more reliable and more accurate observation data for earthquake prediction, this paper systematically orders the earthquake fixed-point geophysical observation in Sichuan Province, which provides a reference for the 14th five-year plan of earthquake observation in Sichuan Province. The results show that the fixed-point geophysical observation in Sichuan Province has a certain scale and has the following characteristics: (1) complete observation means and many observation items; (2) high quality observation data with certain earthquake reflecting ability; (3) many types of observation instruments and comparable observations of the same type; (4) uneven distribution of observation stations; (5) complex observation environment, which should be further strengthened Strong observation and environmental protection.
