TLDR
In this paper, short-term (timescale of hours, days and weeks) earthquake (EQ) prediction is of essential importance to mitigate EQ disasters, which is based on seismic measurement.Abstract:
Short-term (timescale of hours, days and weeks) earthquake (EQ) prediction is of essential importance to mitigate EQ disasters. Short-term EQ prediction has so far been based on seismic measurement...read more

A Survey of Internet of Things (IoT) for Geohazard Prevention: Applications, Technologies, and Challenges
TL;DR: The applications of the IoT in the monitoring and early warning of seven types of common geohazards, including landslides, debris flow, rockfall, surface subsidence, surface collapse, surface cracks, and earthquakes, are surveyed and the challenges are summarized.

Generation of Seismic-Related DC Electric Fields and Lithosphere-Atmosphere-Ionosphere Coupling
Valery Sorokin,Masashi Hayakawa +1 more
TL;DR: In this paper, the influence of earthquake preparation processes on the ionosphere through the electric field and electric current occurring in the global atmosphere-ionosphere electric circuit is considered based on the satellite and ground-based experimental data of electric fields, plasma and electromagnetic perturbations obtained for several days before an earthquake.

Pre-earthquake ionospheric anomalies before three major earthquakes by GPS-TEC and GIM-TEC data during 2015–2017
TL;DR: In this article, the authors presented different time interval of pre-seismic ionospheric anomalies, however, this study showed that EQs ionosphere precursors may occur within 10 days.

Multifractal analysis for the ULF geomagnetic data during the 1993 Guam earthquake
TL;DR: In this paper, the authors have shown that the fractal (monofractal) dimension (Do) showed a significant increase before the Guam earthquake occurred on 8 August, 1993 and carried out the corresponding multifractal analysis (by means of detrended fluctuation analysis) for the same data to study the statistical selfsimilar properties in a wide range of scales.

ULF/ELF emissions observed in Japan, possibly associated with the Chi-Chi earthquake in Taiwan
TL;DR: In this paper, the phase difference of these ELF emissions (BX, BY) was measured, and it was shown that these emissions are linearly polarized, suggesting that they have propagated in the subionospheric waveguide over long distances.
