Abstract

Studies of variations in the parameters of various geophysical fields during the preparation of destructive earthquakes that occurred in Turkey in February 2023 with magnitudes of 6 ≤ M ≤ 7.8 are carried out using satellite data. It has been found that anomalies of these parameters manifested themselves from 34 to 25 days before the earthquakes as a sharp decrease in the values of relative humidity (RHS) and outgoing longwave radiation (OLR), as well as in an increase in the density of local lineaments. An increase in the surface skin temperature (SST), surface air temperature (SAT), RHS, and OLR, as well as in the values of the aerosol optical depth (AOD) and ionospheric total electron content (TEC), was revealed 19–9 days before the analyzed seismic events. In the period from 5 to 2 days before these earthquakes, a decrease in the SST, SAT, the flux of OLR, and the ionospheric TEC, as well as an increase in RHS and in the length of the secants of the rose diagrams of regional lineaments, were recorded. Quantitative characteristics of these anomalies are determined.

2023年2月土耳其破坏性地震准备期间各种地球物理场异常的卫星登记

摘要

利用卫星数据对2023年2月土耳其发生的6≤M≤7.8级破坏性地震准备过程中各种地球物理场参数的变化进行了研究。研究发现，这些参数的异常表现在震前34至25天内，相对湿度（RHS）和出射长波辐射（OLR）值急剧下降，以及密度增加。当地的轮廓。表面皮肤温度 (SST)、表面空气温度 (SAT)、RHS 和 OLR 以及气溶胶光学深度 (AOD) 和电离层总电子含量 (TEC) 值均有所增加 19–分析地震事件前 9 天。震前5～2天，海温、SAT、OLR通量、电离层TEC减小，RHS和区域玫瑰图割线长度增大。轮廓，被记录下来。确定这些异常的数量特征。
