Abstract EN
In the history of earthquake thermal infrared research, it is undeniable that before and after strong earthquakes there are significant thermal infrared anomalies which have been interpreted as preseismic precursor in earthquake prediction and forecasting.
In this paper, we studied the characteristics of thermal radiation observed before and after the 8 great earthquakes with magnitude up to Ms7.0 by using the satellite infrared remote sensing information.
We used new types of data and method to extract the useful anomaly information.
Based on the analyses of 8 earthquakes, we got the results as follows.
(1) There are significant thermal radiation anomalies before and after earthquakes for all cases.
The overall performance of anomalies includes two main stages: expanding first and narrowing later.
We easily extracted and identified such seismic anomalies by method of “time-frequency relative power spectrum.” (2) There exist evident and different characteristic periods and magnitudes of thermal abnormal radiation for each case.
(3) Thermal radiation anomalies are closely related to the geological structure.
(4) Thermal radiation has obvious characteristics in abnormal duration, range, and morphology.
In summary, we should be sure that earthquake thermal infrared anomalies as useful earthquake precursor can be used in earthquake prediction and forecasting.
