“…An infrared temperature abnormal increasing before an earthquake reflects seismotectonic activity (Ouzounov et al, 2004). However, when there are lots of clouds over the epicenter region, the temperature changing will not be recorded correctly.…”

“…Zongjin (1982) also found that there are abnormal warming before the vast majority of the earthquakes when they did geothermal phenomenon investigation of the nine major earthquakes happened during the years from 1966 to 1976. An abnormally increased infrared temperature before an earthquake can reflect seismotectonic activities (Ouzounov et al, 2004).…”

Abstract. The paper introduced the model of the additive tectonics stress from celestial tide-generating force. The model can be used to explain the relationship between additive tectonics stress and seismic fault sliding. According to the periodic changes of the additive tectonics stress, the temperature is analyzes based on the temperature data of NCEP (National Centers for Environmental Prediction) which are gathered for a period of time before and after the Hokkaido, Japan earthquake (25 September 2003). It is found that the abnormal increasing of the temperature is significantly associated with the seismic deformation, even if the epicenter was covered by the clouds. The effect of the additive tectonics stress on activities of the fault is to trigger it at a time when the stress level has already reached an advanced stage as indicated by the temperature increase. Based on this model, it is possible to forewarn short-impending earthquakes.

“…Several studies (see for example Gorny et al, 1988;Qiang and Dian, 1992;Tronin, 1996;Qiang et al, 1997;Tronin et al, 2002;Ouzounov and Freund, 2004) have been performed, in the past years, reporting the appearance of spacetime anomalies in TIR satellite imagery, from weeks to days, before severe earthquakes. Different authors (Qiang et al, 1991;Tramutoli et al, , 2009, in order to explain the appearance of anomalously high TIR records near the place and the time of earthquake occurrence, attributed their appearance to the increase of green-house gas (such as CO 2 , CH 4 , etc.)…”

Abstract. Space-time fluctuations of Earth's emitted Thermal Infrared (TIR) radiation have been observed from satellite months to weeks before earthquakes occurrence.The general RST approach has been proposed in order to discriminate normal (i.e. related to the change of natural factor and/or observation conditions) TIR signal fluctuations from anomalous signal transient possibly associated to earthquake occurrence. In this work RST approach is applied to the Abruzzo 6 April 2009 event (M L =5.8) by using for the first time MSG-SEVIRI (Meteosat Second Generation -Spinning Enhanced Visible and Infrared Imager) thermal infrared observations. A validation/confutation analysis has been performed in order to verify the presence/absence of anomalous space-time TIR transients in the presence/absence of significant seismic activity. MarchApril 2009 has been analyzed for validation purposes. Relatively unperturbed periods (no earthquakes with M L ≥5) have been taken for confutation. A specific TIR anomalies spacetime persistence analysis as well as a cloud coverage distribution test have been introduced in order to eliminate artifacts and outliers both in the validation and confutation phases. Preliminary results show clear differences in TIR anomalies occurrence during the periods used for validation and confutation purposes. Quite clear TIR anomalies appear also to mark main tectonic lines related to the preparatory phases of others, low magnitude (M L ∼4) earthquakes, occurred in the area.

“…A 40-day time period is sufficient for anomaly monitoring (Bhardwaj et al, 2017). The LST prior to earthquakes usually increased by at least 3-5 K Ouzounov and Freund, 2004;Tronin, 2006). A 1-10 K rise of LST two weeks before the main shock of 2011 Tohoku-Oki earthquake was detected around the epicenter (Zoran, 2012).…”

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.
