Counterevidence for an earthquake precursor of satellite thermal infrared anomalies
一次卫星热红外地震前兆现象的证伪

subject of The study on the relation between satellite thermal infrared anomalies and earthquakes is a new seismology in recent years, and yet, how to extract the infrared anomaly really related to which occurred on Mar 24 2004 in eastern Inner Mongolia, anomalies and earthquakes, and explores some problems earthquake This paper, exampled by the Ms5.9 earthquake discusses the connection between thermal infrared on earthquake anomaly extraction. Firstly, the NOAA16 satellite images three months before the earthquake are interpreted and analyzed. As a result, evident thermal infrared anomalies are found, which have following characteristics. The anomalies look like fog in images with even brightness, smooth surfaces and clear bounds, but their temperatures are higher than that of the ground. The locations of the anomalies are changeable, and the areas of the anomalies are variable in size, looking as if the anomalies float above the ground without direction of moving and extending. The magnitude of the anomalies can reach 3 - 10K. Secondly, the NOAA16 satellite images of two years are analyzed, and similar infrared anomalies are found again. An analysis of temporal and spatial evolution processes of the anomalies shows that the anomalies appear in the winter seasonally. It is possible to take the anomalies as earthquake precursor by mistake only depending on those satellite data several days or months before a shock,Finally, the causes of formation for the anomalies are probed, and the conclusion is that they are probably pruduced by atmosphere temperature inversion phenomena, not by the earthquake.
