摘要
The imminent and impending prediction of the three elements of earthquake contributes significantly to loss reduction of earthquake disaster.But this work is difficult to do and remains a global puzzle now.We studied the Lushan earthquake of the 20 April,2013 with the time-spatial evolution rules of satellite infrared warming abnormity and analyzed this abnormality on a conference of the National Natural Disaster Committee on April 21,2013.This article briefly analyzes the tectonic setting and mechanism of the Lushan earthquake.The Lushan earthquake is an MS 7 earthquake that occurred in the western earthquake area of China,and the earthquake mechanism is similar to that of Wenchuan earthquake.The Indian plate pushed against the Tibetan block along the NE direction,forming a fault block with a gliding direction of SEE.This fault block was blocked strongly by Longmen Mountain fault zone west of Sichuan Basin.The accumulated energy was released and the earthquake occurred.The tectonic activities before earthquake may cause a series of changes in infrared warming abnormity,and we can study these changes to predict earthquake.The evolution of the changes includes four phases: initial temperature increase,heightened temperature increase,peak temperature increase,and temperature decline with the occurrence of earthquake.
