Atellitic thermal infrared brightness temperature anomaly image—short-term and impending earthquake precursors

Mechanism of satellitic thermo-infrared brightness temperature and temperature increaming is studied. Experiments are made with a gas sample taken around the epicenter area. The gas ample is pmved to contain green house gases such as CH4, and CO2 which have increased by tens of thousands of times. In addition, lab research slso pmes that CH4, and CO2 can obtain energy under the action of transient electric field and release heat, thus reeulting in a temperature increase of 2–6°C. Also a brief account of practices since 1990 is given; altogether 40 short-tenn and impending earthquake predictions have been made, with 9 precise ones whose three main factors of an earthquake are clearly depicted, and 12 fairly good ones. These predictions include 3 earthquakes ofM.⩾ 7, 4 ofM.⩾ 6.0 and the rest are mundM. 5.0. Yet there are earthquakes left out of prediction. Finally the evolutionwy processing characters of satellitic thermo-infrared brightness temperature and temperature increase before the Lijiang earthquake on Feb. 3, 1996 and Tangshan earthquake on April 14, 1998 are introduced in detail. The conclusion makes a study on the regularities of connection among time, space and stress when there appears the satellitic thermal-inlinred brightness tempera- and temperature increasing anomaly.
