Abstract

Using remote sensing data, we study the changes in lineament systems during the preparation and process of strong earthquakes with М = 7.1 and М = 6.4 which occurred in California (United States) in July 2019. The series of satellite images shot from January 1, 2019, to August 12, 2019, and the data on seismic setting in the region are analyzed. The precursory changes are revealed in the lineament systems; these changes are expressed in rose diagrams of regional lineaments and in summarized length of local lineaments of different directions. An abrupt change in quantitative characteristics of rose diagrams of lineaments began to manifest on June 5, 2019 (i.e., a month before the earthquake of July 4 and 5, 2019). It is established that the maximum length of lineaments striking to the northwest and northeast (corresponding to the longitudinal and transverse strikes relative to the main regional structural features) was reported on June 30, 2019 (i.e., several days before the strong earthquakes).

利用卫星图像检测加利福尼亚州发生6.4和7.1级强烈地震时的Lineament系统异常

摘要

利用遥感数据，我们研究了在М = 7.1和М强地震的准备和过程中，线系统的变化= 6.4，发生于2019年7月在美国加利福尼亚州。分析了从2019年1月1日到2019年8月12日拍摄的一系列卫星图像以及该地区的地震背景数据。前世的变化在世系系统中显现出来。这些变化用区域图的玫瑰图和不同方向的局部图的汇总长度表示。玫瑰色线条图的定量特征的突然变化开始于2019年6月5日（即2019年7月4日和5日地震前一个月）。可以确定的是，在2019年6月30日报告了撞击西北和东北的直线最大长度（对应于相对于主要区域结构特征的纵向走向和横向走向）
