Special Issue Information

Dear Colleagues,

Following the successful previous Special Issue (https://www.mdpi.com/journal/remotesensing/special_issues/LAIC_EarthquakePrecursors), we launched a second edition, integrating new topics. The aim of this Special Issue is to collect papers that use remote sensing, especially satellite data and new methodologies, to understand the preparatory phase of medium–large earthquakes in the world and other natural hazards like volcano eruptions, extreme weather, and geomagnetic storms/substorms. In the last decades, several satellite observations have been used not only for co-seismic precise effects estimation (such as ground displacement estimated by the InSAR technique) but also to search for possible precursor signals. Some satellites have been launched for this purpose, such as DEMETER (Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions), which flew from 2004 to 2010, and the CSES (China Seismo Electromagnetic Satellite) mission, which is composed of CSES-01, launched in orbit on 2 February 2018, and its successor, CSES-02, which was recently launched on 14 June 2025. Other satellites, especially those dedicated to Earth Observation, such as MODIS on TERRA/AQUA by NOAA or Swarm by ESA, provide crucial remote sensing data that are very useful for investigating possible pre-earthquake signals. For example, detecting bursts of particles and ionospheric disturbances several months or a few hours before the occurrence of medium–large earthquakes.

Furthermore, papers concerning earthquake investigations using remote sensing data are precious for understanding the physics and mechanisms of such phenomena.

We welcome papers that explore the statistical significance of pre-earthquake processes that occurred in the lithosphere, atmosphere and ionosphere, as detected by ground observations or satellite and or other methods. Papers with deterministic, empirical, or analytical models studying the preparation phase of the earthquakes including, but not limited to, the lithosphere, atmosphere, and ionosphere coupling (LAIC) effects are also welcome.

The interaction of different Earth layers, the so-called lithosphere, atmosphere, ionosphere coupling, has also been proposed on the occasion of volcano-eruption, both as a pre-eruption phenomenon as well as a co-volcanic disturbance. We welcome papers that investigate active volcanoes using remote sensing to determine their potential hazard and their influence on the atmosphere and ionosphere.

This Special Issue also seeks to advance our understanding of other significant natural hazards, such as extreme weather (tropical cyclones/hurricanes/typhoons, heavy rainfall, storm surges, tornadoes, thunderstorms with high lightning activity and flash flooding), as well as geomagnetic storms/substorms. Such geomagnetic storm phenomena include ionospheric irregularities and the magnetospheric–ionospheric–atmospheric coupling. Studies using satellite data, eventually integrated with ground-based observations, numerical modelling, and artificial intelligence approaches, are particularly encouraged for submission.

Research on new case studies (earthquakes, volcanic eruptions, geomagnetic storms and other natural hazards), reviews, new methods, ideas of future perspectives and applications to investigate the interactions between the geo-layers are warmly welcome.

This study investigates pre-seismic ionospheric Total Electron Content (TEC) disturbances preceding the Mw 6.9 Northern Aegean Sea earthquake of 24 May 2014 using observations from 13 Global Navigation Satellite System (GNSS) stations. A pronounced negative TEC disturbance was identified on 22 May 2014, approximately two days before the earthquake, under comparatively quiet solar and geomagnetic conditions. Station-wise Z-score analysis, which expresses the TEC departure from the reference mean in units of standard deviation, revealed significant negative deviations across the network, while inter-station correlations indicated a temporally coherent but spatially heterogeneous ionospheric response. To characterize the disturbance beyond peak-based measures, the TEC Anomaly Significance Index (TASI) was developed by integrating the mean absolute Z-score, coefficient of variation, and Shannon entropy. TASI showed strong agreement with the maximum absolute Z-score ranking (Spearman’s ρ=0.89, p<0.001) while providing greater sensitivity to cumulative and persistent anomaly behaviour. It exhibited stronger associations than maximum Z for six of the seven evaluated temporal descriptors, particularly those representing anomaly duration and consecutive persistence. Among the analyzed GNSS stations, KASI recorded the highest TASI despite not being the nearest station to the epicenter, indicating that anomaly significance was not governed solely by epicentral distance. The proposed framework provides a multidimensional, network-based approach for characterizing potential pre-seismic ionospheric disturbances and establishes a basis for future multi-event and control-period validation.

We report on electric field measurements recorded onboard the China Seismo-Electromagnetic Satellite (CSES). In this study, we emphasize the whistler and transmitter very low frequency (VLF) radiations recorded in the frequency range between 1.8 kHz and 25 kHz. The electric field detector (EFD) instrument onboard the CSES works as a double probe instrument and allows access to the three electric components of VLF waves. Three frequencies were selected, two related to whistler hiss (i.e., 2.5 kHz channel) and chorus (i.e., 5 kHz channel) radiations and one to the NAA ground-based transmitter signal (i.e., 24 kHz). We investigate the corresponding power spectral density variations, from which we derive the Stokes intensity I and normalized q linear polarization components. This leads us to study their statistical fluctuations and to emphasize the behaviors of natural whistler hiss and chorus radiations and man-made transmitter emissions. The Stokes intensities of the natural whistler and NAA transmitter radiations are estimated, respectively, to be about 1 mV2 m−2 Hz−1 and 0.05 mV2 m−2 Hz−1. The correlation coefficients of the Stokes intensity polarizations are in the order of 98% powerfully coupled, contrary to the Stokes normalized linear polarizations, which are found to be relatively paired, i.e., less than 60%. The signal-to-noise ratio is estimated considering three intensity levels (i.e., high, medium, low). This analysis leads us to characterize the Stokes normalized linear components of VLF radio waves and to show different behaviors of the polarization when considering the Northern and Southern Hemispheres. The regions of enhanced whistler Stokes intensities of whistler hiss and chorus emissions are confined to the sub-auroral regions in both hemispheres, particularly at geomagnetically ranges linked to the NAA transmitter station and its conjugate region in the Southern Hemisphere. In this investigation, we point out the Stokes polarization parameters, which are essential for the characterization of whistler VLF radio waves, particularly when considering the CSES mission objectives and commitments.

Identifying reliable earthquake precursors remains a major challenge in geophysics. Among the most widely investigated candidates are seismicity-based indicators, such as the Gutenberg–Richter b-value, and ionospheric disturbances expressed through Total Electron Content (TEC) anomalies. However, these observables are commonly investigated independently, and their quantitative spatial relationship remains poorly constrained. This study investigates the spatio-temporal evolution of b-values and GNSS-derived TEC anomalies preceding the 2019 Ridgecrest (Mw 7.1) and 2010 Baja California (Mw 7.2) earthquakes. Temporal analyses reveal progressive reductions in b-values prior to both earthquakes, while spatial mapping identifies localized low-b regions with thresholds of b0.88 for Ridgecrest and b0.83 for Baja California. Independent TEC analyses reveal negative ionospheric anomalies of approximately 2.34 TECU and 4.27 TECU, occurring 9–10 days and ~2 days before the respective mainshocks under geomagnetically quiet conditions. A multi-scale centroid-based spatial validation framework, incorporating both global and local low-b centroids together with Monte Carlo randomization tests, demonstrates that the dominant low-b regions consistently exhibit the closest spatial correspondence with the TEC depletion. The observed centroid separations occupied only a limited fraction of the theoretical earthquake preparation zone, with normalized distances of 0.33 and 0.24 for the global centroids, decreasing to 0.32 and 0.17, respectively, for the dominant local low-b regions. Overall, the results support a stress-conditioned lithosphere–atmosphere–ionosphere coupling framework and demonstrate that integrating long-term seismic stress evolution with GNSS-derived ionospheric observations provides an objective multi-parameter framework for investigating the spatial organization of earthquake preparation processes.
