“…A lot of authors (Wang and Zhou, 1984;Gorny et al, 1988;Qiang, Xiu-Deng, and Chang-Gong, 1991;Tronin, 1996;Tramutoli et al, 2001;Ouzounov and Freund, 2004;Choudhury et al, 2006a;Panda et al, 2007;Saraf et al, 2009;Chen et al, 2011, Blackett, Wooster and Malamud, 2011, Guangmeng, 2012Qin et al, 2012;Sulçe, 2013) have found that surface air temperature increases in a close proximity to the future earthquake's epicentre. Other papers report for systematic changes of geomagnetic field prior to earthquakes (EQ) (Hayakawa et al, 1996;Mavrodiev, 2004;Kilifarska, Nedialkov and Velichkova, 2015a).…”

“…This wave band, however, is highly sensitive to the amount of water vapour in the lower troposphere (Kilifarska, 2012), so the "skin" temperature measured by the satellites could substantially deviates from the ground based temperature measurement. This effect has been noticed by Chinese scientists (Chen et al, 2011), who pay attention that groundbased and satellite measurements of the high frequency fluctuations (with period 10 days or less) of the surface temperature are uncorrelated. For this reason this paper is focused on analysis of ERA-Interim reanalysis, providing two near surface temperaturesthe air temperature at 2 m above the surface and the soil temperature at ~3 m below the surface.…”

This paper is focused on the short-term variations of near surface temperature (T) obtained over a period of one week prior to the earthquake occurrence (EQ). We found a systematic temperature increase in almost the entire examined area (i.e. 8˚-30˚E and 35˚-53˚N), reaching a maximum in Aegean-Balkans-Pannonia basin region. Total of 1039 EQs have been analysed, what ensures statistical significance of our results. Comparison with the spatial distribution of geomagnetic variability reveals a striking similarity between pre-EQ variations of geomagnetic diurnal amplitude and surface T variability. This result suggests that relations between lithosphere and atmosphere, detected in the latest phase of EQ preparation, are possibly connected to the corresponding changes of geomagnetic field, initiated by the stress and strain remagnetization/demagnetisation of rocks, just before their destruction. The mechanism for such lithospheric-atmospheric relations, suggested in this paper, requires corresponding changes in the near tropopause ozone and humidity, and our further analyses confirm their synchronous variations with geomagnetic field and surface temperature. This result indicates that geomagnetic variations of a lithospheric origin could drive the temporal co-variations of meteorological variables. The physical mechanism of geomagnetic influence is briefly discussed in the paper.

“…The MODIS (http://modis.gsfc.nasa.gov, accessed on 25 March 2023) is a payload on board the satellite with 36 optical channels, six of which provide detection information related to land surface temperature (LST) [18]. A comparative study of LSTs obtained by field measurements and satellite remote sensing indicated that there was no substantial difference between the results of the dayside and nightside data for the anomaly analysis on a monthly scale [47]. In addition, the environmental disturbances were mostly high-frequency information, and the radiation anomalies associated with major EQs were mostly low-frequency information.…”

The Analysis of Lithosphere–Atmosphere–Ionosphere Coupling Associated with the 2022 Luding Ms6.8 Earthquake

Taking the Luding Ms6.8 earthquake (EQ) on 5 September 2022 as a case study, we investigated the potential seismic anomalies of the ionosphere, infrared radiation, atmospheric electrostatic field (AEF), and hot spring ions in the seismogenic region. Firstly, we analyzed the multi-parameter anomalies in the ionosphere around the epicenter and found synchronous anomalous disturbances in the ground parameters, namely the global ionospheric map (GIM), GPS, TEC, and satellite parameters, such as the He+ and O+ densities on 26 August under relatively quiet solar–geomagnetic conditions (F10.7 < 120 SFU; Kp < 3; Dst > −30 nT; |AE| < 500 nT). Next, both the anomaly analysis of the infrared radiation and AEF, and the survey results of the Luding EQ scientific expedition on the hot spring ions showed pre-seismic anomalous variations at different time periods in the seismogenic region. The characteristics of Earth’s multi-sphere coupling anomalies in temporal evolution and spatial distribution were obvious, which validated the Lithosphere–Atmosphere–Ionosphere Coupling (LAIC) mechanism. Finally, combining the analysis results and the LAIC mechanism, we suggested that the multi-sphere coupling anomalies were more likely associated with the Luding Ms6.8 EQ, and that the differential motion and the regional crustal stress accumulation between the Chuandian block and the Bayan Har block might have led to this EQ. Furthermore, remote sensing and ground-based monitoring technologies can play an important role in corroborating and compensating each other, while further study of the multi-sphere coupling mechanism will provide a clearer understanding of the seismogenic process for major EQs.

“…In this manner, Tralli et al (2007) present a conceptual case for the assimilation of InSAR measurements into the HAZUS-MH earthquake module. Based on data from thermal sensors, short-term temperature increases prior to several earthquake events have been described numerous times for both surface and atmosphere (Gorny et al 1988;Tronin 1996;Ouzounov & Freund 2004;Saraf & Choudhury 2005;Ouzounov et al 2006;Choudhury et al 2006;Yurur 2006;Ouzounov et al 2007;Yang & Guo 2010;Saradjian & Akhoondzadeh 2011;Chen et al 2011), what may hold information for earthquake prediction and warning (see also Saraf et al (2009) for a discussion of reasons of correlation of these phenomena). Also, other anomalies related to earthquakes that can be detected by remote sensing instruments are discussed in the literature (Tronin 2010) such as ionospheric (Kakinami et al 2010) or cloud (Gup & Xie 2007) anomalies.…”

Remote sensing data and methods are widely deployed in order to contribute to the assessment of numerous components of earthquake risk. While for earthquake hazard related investigations the use of remotely sensed data is an established methodological element with a long research tradition, earthquake vulnerability centered assessments incorporating remote sensing data are increasing primarily in recent years. This goes along with a changing perspective of the scientific community which considers the assessment of vulnerability and its constituent elements as a pivotal part of a comprehensive risk analysis. Thereby, the availability of new sensors systems enables an appreciable share of remote sensing first. In this manner, a survey of the interdisciplinary conceptual literature dealing with the scientific perception of risk, hazard and vulnerability reveals the demand for a comprehensive description of earthquake hazards as well as an assessment of the present and future conditions of the elements exposed. A review of earthquake related remote sensing literature, realized both in a qualitative and quantitative manner, shows the already existing and published manifold capabilities of remote sensing contributing to assess earthquake risk. These include earthquake hazard related analysis such as detection and measurement of lineaments and surface deformations in pre-and post-event applications. Furthermore, pre-event seismic vulnerability centered assessment of the built and natural environment and damage assessments for post-event applications are presented. Based on the review and the discussion of current scientific foci and research projects first steps towards a roadmap for remote sensing is drawn, explicitly taking scientific, technical, multi-and transdisciplinary as well as political perspectives into account, which is intended to open possible future research activities.
