Pre-seismic ionospheric anomalies detected before the 2016 Taiwan earthquake [PDF]
, 2019 On Feb. 5 2016 (UTC), an earthquake with moment magnitude 6.4 occurred in southern Taiwan, known as the 2016 (Southern) Taiwan earthquake. In this study, evidences of seismic earthquake precursors for this earthquake event are investigated.

On the puzzling feature of the silence of precursory electromagnetic emissions [PDF]
, 2013 It has been suggested that fracture-induced MHz-kHz electromagnetic (EM) emissions, which emerge from a few days up to a few hours before the main seismic shock occurrence permit a real-time monitoring of the damage process during the last stages of ...

On the evolution of elastic properties during laboratory stick-slip experiments spanning the transition from slow slip to dynamic rupture [PDF]
, 2016 The physical mechanisms governing slow earthquakes remain unknown, as does the relationship between slow and regular earthquakes. To investigate the mechanism(s) of slow earthquakes and related quasi-dynamic modes of fault slip we performed laboratory ...

A Machine Learning‐Based Detection of Earthquake Precursors Using Ionospheric Data
Radio Science, 2020 Detection of precursors of strong earthquakes is a challenging research area. Recently, it has been shown that strong earthquakes affect electron distribution in the regional ionosphere with indirectly observable changes in the ionospheric delays of GPS ...

Wavelet analysis of the LF radio signals collected by the European VLF/LF network from July 2009 to April 2011 [PDF]
, 2012 In 2008, a radio receiver that works in very low frequency (VLF; 20-60 kHz) and LF (150-300 kHz) bands was developed by an Italian factory. The receiver can monitor 10 frequencies distributed in these bands, with the measurement for each of them of the ...
