PLoS ONE, 2021 Infrasonic signals measured before an earthquake carry information about the size and development speed of the source fracture, the stress at the fracture site and the elastic properties of the geologic medium.

Radon as earthquake precursor [PDF]
, 2012 Earthquake predictions are based mainly on the observation of precursory phenomena. However, the physical mechanism of earthquakes and precursors is at present poorly understood, because the factors and conditions governing them are so complicated. Methods of prediction based merely on precursory phenomena are therefore purely empirical and involve ...

Origin of Earthquake Light Associated with Earthquakes in Christchurch, New Zealand, 2010-2011
Earth Sciences Research Journal, 2015 Earthquake light (EQL) mainly blue-white flashes from the ground, was observed coseismically during a NewZealand M7.1 earthquake, (4.47 am 4-Sep-2010 local time). A local production mechanism is most probable.

Reverse Detection of Short-Term Earthquake Precursors [PDF]
, 2003 We introduce a new approach to short-term earthquake prediction based on the concept of selforganization of seismically active fault networks. That approach is named "Reverse Detection of Precursors" (RDP), since it considers precursors in reverse order ...

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 ...

Re-examination of log-periodicity observed in the seismic precursors of the 1989 Loma Prieta earthquake [PDF]
, 2000 Based on several empirical evidence, a series of papers has advocated the concept that seismicity prior to a large earthquake can be understood in terms of the statistical physics of a critical phase transition.

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 ...

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 ...
