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 ...

IEEE Access, 2019 Kernel-based two-dimensional principal component analysis (K2DPCA), a nonlinear method, was performed to examine ionospheric 2-D total electron content (TEC) variations obtained from the NASA Global Differential GPS (GDGPS) network, which consisted of ...

Hydrogeological Earthquake Precursors: A Case Study From the Kamchatka Peninsula
Frontiers in Earth Science, 2020 The relevance of hydrogeological precursors (HGPs) study is justified by the need to obtain reliable information about the spatio-temporal manifestations and the relationships of HGPs with the parameters of subsequent earthquakes for seismic forecasting.

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 ...

Prediction of the date, magnitude and affected area of impending strong earthquakes using integration of multi precursors earthquake parameters [PDF]
Natural Hazards and Earth System Sciences, 2011 Usually a precursor alone might not be useful as an accurate, precise, and stand-alone criteria for the earthquake parameters prediction. Therefore it is more appropriate to exploit parameters extracted from a variety of individual precursors so that ...

Georesistivity precursors to the Tangshan earthquake of 1976
Annals of Geophysics, 1997 Georesistivity precursors and corresponding coseismic effects to the Tangshan earthquake of 1976 are given as follows: 1) resistivity measurements with accuracies of 0.5% or better for over 20 years show that resistivity decreases of several percent ...
