Analysis of Thermal Anomaly Characteristics of Luodian Earthquake Swarm in 2024
摘要
Abstract
The thermal infrared anomaly was extracted by using wavelet transform and relative power spectrum based on the brightness temperature product of Chinese geostationary meteorological satellite FY-2G infrared remote sensing.A thermal infrared anomaly analysis of the Luodian earthquake swarm in Guizhou Province in late June of 2024 was conducted,and the results show that on June 14,The NNW-trending thermal infrared anomaly in the southeastern tip of the Weining Yi,Hui,and Miao Autonomous County-Shuicheng fault,the Bama-Bobai fault,and the Nandan-Hechi fault,with the maximum relative power spectrum more than 16 times,and the anomaly is significant.Based on the analysis of the focal mechanism solutions of eight earthquakes with M≥3,it is found that the main rupture direction of the earthquake is consistent with the characteristics of thermal anomaly.关键词
