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

Fractal evolution of MHz electromagnetic signals prior to earthquakes: results collected in Greece during 2009
Ermioni Petraki,Dimitrios Nikolopoulos,Yiannis Chaldeos,Grigorios Koulouras,Constantinos Nomicos,Panayiotis H. Yannakopoulos,Sofia Kottou,J. Stonham +7 more
TL;DR: In this paper, a fractal evolution of 11 one-month lasting MHz electromagnetic disturbances, recorded in Greece prior to nine significant earthquakes of 2009, was analyzed using time-space wavelet-based power spectral techniques.

Significant ELF perturbations in the Schumann Resonance band before and during a shallow mid-magnitude seismic activity in the Greek area (Kalpaki)
Vasilis Christofilakis,Giorgos Tatsis,Constantinos I. Votis,Ioannis Contopoulos,Christos Repapis,V. Tritakis +5 more
TL;DR: In this article, strong ELF perturbations in the Schumann Resonance band (0-50 Hz) were detected in the North of Greece close to the village of Kalpaki during a shallow (17 km) mid-magnitude earthquake (5,3R) and the post-seismic sequence that followed it.

Earthquake induced dynamics at the ionosphere in presence of magnetic storm
TL;DR: In this paper, the authors examined the changes induced in the dynamics of the ionosphere by the major Japan earthquake (EQ) of March 11, 2011 (epicenter at 38.322°N, 142.369°E, M = 8.9) in presence of a magnetic storm by mapping latitudinal variations of F-layer ionization density (NmF2) from 22 stations covering the epicenter zone.

An evidence on the lithosphere-ionosphere coupling in terms of atmospheric gravity waves on the basis of a combined analysis of surface pressure, ionospheric perturbations and ground-based ULF variations
TL;DR: Hayakawa et al. as mentioned in this paper analyzed the wavelet spectra between the ionospheric perturbation and the ground-based ULF fluctuation, which may provide a convincing support to the AGW channel of LAI coupling.

Changes in total electron content associated with earthquakes (M > 5) observed from GPS station, Varanasi, India
TL;DR: In this paper, the changes in the total electron content (TEC) derived from the global positioning system (GPS) at Varanasi (latitude 25.3° N, longitude 82.99° E), India has been measured during 2007 and 2010.

Estimation of the size of earthquake preparation zones
TL;DR: In this article, an approximate solution of the problem for a soft elastic inclusion in an elastic half-space is presented. But the authors assume that the moduli of the inclusion differ slightly from those of the surrounding medium (by no more than 30%).
