什么是地震活动性图象 地震活动性图象,主要指前兆性地震活动性图象,以研究强震发生前地震活动本身的演变规律为目的。其基本思想是:地震活动性图象是深部构造应力场的一种反映。后期的地震活动与前期的地震活动是直接有关的。因之,可以利用地震活动性图象达到所谓“以震报震”或“以小地震预报大地震”的目的。 既然地震活动性图象是以前期的地震来预测后期 What is the seismicity image? Seismicity image, mainly referring to the precursory seismicity image, aiming at studying the evolution law of the seismic activity itself before the strong earthquake. The basic idea is that seismicity images are a reflection of deep tectonic stress field. Late seismic activity and seismic activity is directly related. Therefore, we can use the seismicity images to achieve the so-called “earthquakes” or “small earthquakes forecast earthquake.” Since the seismicity image is based on previous earthquakes to predict the later period
