PRINCIPLE AND METHODS OF EARTHQUAKE PREDICTION BY TEMPERATURE REMOTELY SENSED

Thermal anomaly appearing before strong earthquakes is an universal phenomenon, and monitoring the changes in temperature can become an useful approach for earthquake prediction. Theraml-IR imagery Processed with meteorological satellite remote sensing data can meet the needs of earthquake prediction through temperature analysis for its short period, high resolution, high accuracy and other superiority. Some of foundational research and preliminary applications demonstrate that temperature remotely sensed can be used as an approach to earthquake prediction. The approach includes four steps: (1) analysis for spacial and temporal relationship between earthquake and thermal anomaly; (2) analysis for temperature background in a given area; (3) atmosphere correction; and (4) monitoring and predicting. The application in Linfen area is introduced, and some exsisting problems, such as meteorological factors., cause of thermal anomaly pre-earthquake are discussed.
