“…The magnitude of the earthquake was 6.6 and the city of Bam was destroyed. Analyses of the daytime and nighttime datasets for the Bam region showed a distinct anomaly in LST which appeared before the main shock [41]. The temperature increase was about 5-7 °C above the usual temperature of the region.…”

A wide range of satellite methods is applied now in seismology. The first applications of satellite data for earthquake exploration were initiated in the '70s, when active faults were mapped on satellite images. It was a pure and simple extrapolation of airphoto geological interpretation methods into space. The modern embodiment of this method is alignment analysis. Time series of alignments on the Earth's surface are investigated before and after the earthquake. A further application of satellite data in seismology is related with geophysical methods. Electromagnetic methods have about the same long history of application for seismology. Stable statistical estimations of ionosphere-lithosphere relation were obtained based on satellite ionozonds. The most successful current project "DEMETER" shows impressive results. Satellite thermal infra-red data were applied for earthquake research in the next step. Numerous results have confirmed previous observations of thermal anomalies on the Earth's surface prior to earthquakes. A modern trend is the application of the outgoing long-wave radiation for earthquake research. In '80s a new technology-satellite radar interferometry-opened a new page. Spectacular pictures of co-seismic deformations were presented. Current researches are moving in the direction of pre-earthquake deformation detection. GPS technology is also widely used in seismology both for ionosphere sounding and for ground movement detection. Satellite gravimetry has demonstrated its first very impressive results on the example of the catastrophic Indonesian earthquake in 2004. Relatively new applications of remote sensing for seismology as atmospheric sounding, gas observations, and cloud analysis are considered as possible candidates for applications.

“…(There is also little prospect of high-altitude clouds being affected in this way, such as those formed from ice). The thermal anomalies identified could also be generated by similar surface outgassing, such as the infra-red absorbing gases of carbon dioxide and methane (Saraf et al, 2008).…”

“…Typically these are equivalent to a temperature change of a few Kelvin, beyond the natural variability (Tramutoli et al, 2005), appearing some days before the earthquake (e.g. Saraf et al, 2008;Guo and Wang, 2008).…”

“…Most studies use nighttime LST data for analysis due to the absence of solar heating, leading to measurements that are predominantly gathered from surface and underground thermal sources. However, daytime LST data can also show significant thermal anomalies (Blackett et al, 2011;Panda et al, 2007;Saraf et al, 2008).…”

Abstract. Detecting thermal anomalies prior to strong earthquakes is a key in understanding and forecasting earthquake activities because of its recognition of thermal radiation-related phenomena in seismic preparation phases. Data from satellite observations serve as a powerful tool in monitoring earthquake preparation areas at a global scale and in a nearly real-time 10 manner. Over the past several decades, many new different data sources have been utilized in this field, and progressive anomaly detection approaches have been developed. This paper dedicatedly reviews the progress and development of preseismic thermal anomaly detection technology in this decade. First, precursor parameters, including parameters from the top of the atmosphere, in the atmosphere, and on the Earth's surface, are discussed. Second, different anomaly detection methods, which are used to extract thermal anomalous signals that probably indicate future seismic events, are presented. Finally, certain 15 critical problems with the current research are highlighted, and new developing trends and perspectives for future work are discussed. The development of Earth observation satellites and anomaly detection algorithms can enrich available information sources, provide advanced tools for multilevel earthquake monitoring and improve short-and medium-term forecasting, which should play a large and growing role in pre-seismic thermal anomaly research.
