Abstract
In this paper, STD (standard deviation) threshold method was proposed using to detect OLR (Outgoing Longwave Radiation) seismic anomalies. OLR data describe the radiation information from the top of the atmosphere, which be thought to reflect the energy changes of earth-atmosphere system prior to earthquakes. The method to identifying seismic anomaly and non-seismic anomaly has been proposed in this work. Based on this, Wenchuan Sichuan, May 12, 2008, Ms8.0 and Delingha, Qinghai, November 10, 2008, Ms6.3 have been studied respectively using STD threshold method. The results indicate that the seismic infrared radiation anomalies can be detected using STD threshold method. And these anomalies can reflect the process of earthquake preparation. At the same time, the spatial distributions of OLR anomalies have some indication effect on judge the seismogenic structure and the epicenter.Keywords
