Slip weakening, strain and short-termpreseismic disturbances

Annals of Geophysics, 2004
The problem of short-term earthquake precursors is discussed. In contrast to the increasing number of reports on short-lived precursors of various types, direct strain measurements cannot detect clearly expressed preseismic anomalies, as follows from the

Spatial–temporal variations of b-values prior to medium-to-large earthquakes in Taiwan and the feasibility of real-time precursor monitoring

Earth, Planets and Space
This study explores the b-value variations prior to M ≥ 6.0 earthquakes in Taiwan, examining their potential as earthquake precursors. Focusing on the 2018 Hualien earthquake and others between 1999 and 2021, we found that many large earthquakes occurred

Spatial and temporal b-value precursors preceding the 2008 Wenchuan, China, earthquake (Mw = 7.9): implications for earthquake prediction

, 2020
The sudden and unexpected Wenchuan earthquake (Mw = 7.9) occurred on the Longmen Shan Fault without any definite precursors. Therefore, a new computing strategy of b-values was applied in the study area around the epicenter of the Wenchuan mainshock ...

Multiparameter monitoring of short-term earthquake precursors and its physical basis. Implementation in the Kamchatka region

, 2016
We apply experimental approach of the multiparameter monitoring of short-term earthquake precursors which reliability was confirmed by the Lithosphere-Atmosphere-Ionosphere Coupling (LAIC) model created recently [1].

The synergy of earthquake precursors [PDF]

Earthquake Science, 2011
The system of geophysical shells (lithosphere, atmosphere, ionosphere) is considered as an open complex nonlinear system with dissipation where earthquake preparation could be regarded as a self-organizing process leading to the critical state of the system.

Foundations for an Operational Earthquake Prediction System

Geosciences
Earthquake prediction is one of the most challenging enterprises of science. Any prediction system must be based on the search for a precursor appearing during the preparation phase of an earthquake in the ground, atmosphere, or ionosphere that can ...

Electromagnetic Pre-earthquake Precursors: Mechanisms, Data and Models-A Review

, 2015
This paper is a survey of pre-earthquake short-term electromagnetic precursors. Extensive studies were carried out the last decades in analysis of electromagnetic emissions from 10-3 Hz up to MHz.

On the existence of earthquake precursors

Annals of Geophysics, 1999
Earthquake prediction based on precursors can aim to provide fully quantified, time-varying, synoptic forecasts, which do not depart from physical and geological principles, and are amenable to formal testing.
