- Abstract
Using MODIS thermal infrared data of satellite and geostationary satellite thermal infrared brightness temperature data for Wen ' an 5.1 earthquake in Hebei province during 2006, the temporal and spatial characteristics of the earthquake were systematically calculated and analysed. Studies show that the anomaly value does exist in both the heat penetrability index and the anomaly ratio about a month before the earthquake. During the earthquake, the process of the thermal infrared anomaly change had experienced from large-range to concentrated then gradually to dissipation, and the maximum value appeared closely near the epicenter.
