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 ...

Normal fault earthquakes or graviquakes [PDF]
, 2015 Earthquakes are dissipation of energy throughout elastic waves. Canonically is the elastic energy accumulated during the interseismic period. However, in crustal extensional settings, gravity is the main energy source for hangingwall fault collapsing ...

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 ...

Influence of seismic activity on the atmospheric electric field in Lisbon (Portugal) from 1955 to 1991 [PDF]
, 2012 In the present study, we considered the influence of seismic activity on the atmospheric electric field recorded at Portela meteorological station (Lisbon, Portugal) for the period from 1955 to 1991.

From Hector Mine M7.1 to Ridgecrest M7.1 Earthquake. A Look from a 20-Year Perspective
Atmosphere, 2021 The paper provides a comparative analysis of precursory phenomena in the ionosphere and atmosphere for two strong earthquakes of the same magnitude M7.1 that happened in the same region (North-East from Los Angeles) within a time span of 20 years, the ...
