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.

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 ...

Observations of stress relaxation before earthquakes [PDF]

, 2004
Theory and observations suggest that seismic shear wave splitting, caused by fluid-saturated stress-aligned microcracks, directly monitors low-level deformation before fracturing, faulting and earthquakes occur.

Kalman Filter, ANN-MLP, LSTM and ACO Methods Showing Anomalous GPS-TEC Variations Concerning Turkey’s Powerful Earthquake (6 February 2023)

Remote Sensing, 2023
On 6 February 2023, at 1:17:34 UTC, a powerful Mw = 7.8 earthquake shook parts of Turkey and Syria. Investigating the behavior of different earthquake precursors around the time and location of this earthquake can facilitate the creation of an earthquake

On the electric field transient anomaly observed at the time of the Kythira M=6.9 earthquake on January 2006 [PDF]

Natural Hazards and Earth System Sciences, 2007
The study of the Earth's electromagnetic fields prior to the occurrence of strong seismic events has repeatedly revealed cases were transient anomalies, often deemed as possible earthquake precursors, were observed on electromagnetic field recordings of ...

Is It Possible to Predict Strong Earthquakes?

, 2014
The possibility of earthquake prediction is one of the key open questions in modern geophysics. We propose an approach based on the analysis of common short-term candidate precursors (2 weeks to 3 months prior to strong earthquake) with the subsequent ...

Electro-Magnetic Earthquake Bursts and Critical Rupture of Peroxy Bond Networks in Rocks

, 2006
We propose a mechanism for the low frequency electromagnetic emissions and other electromagnetic phenomena which have been associated with earthquakes. The mechanism combines the critical earthquake concept and the concept of crust acting as a charging ...

EARTHQUAKE OF 27 AUGUST 2008 IN THE SOUTHERN BAIKAL AREA AND ITS PRECURSORS

Геодинамика и тектонофизика, 2015
On 27 August 2008, a strong earthquake occurred in the Southern Baikal area. Its focus was located within the Baikal rift zone which characterized with high seismicity. The general location and approximate strength of the earthquake were thus expectable,
