From Hector Mine M7.1 to Ridgecrest M7.1 Earthquake. A Look from a 20-Year Perspective

open access: yesAtmosphere, 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 ...

An earthquake precursor mobile network

open access: yesEarthquake Science, 2021
It is known that the VLF/LF radiation existing prior to large earthquakes is recorded in several seismically active countries of the world. The networks of this radiation consist of stationary transmitters and receivers. However, there are cases of large earthquakes, when existing networks cannot detect relevant EM radiation.

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

open access: yesRemote 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

Earthquake precursors in the light of peroxy defects theory: Critical review of systematic observations [PDF]

open access: yes, 2017
Forecasting earthquakes implies that there are time-varying processes, which depend on the changing conditions deep in the Earth's crust prior to major seismic activity. These processes may be linearly or non-linearly correlated.

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

open access: yesNatural 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 ...

The challenges and possibilities of earthquake predictions using non-seismic precursors

open access: yes, 2021
The catastrophic magnitude of life and monetary losses associated with earthquakes deserve serious attention and mitigation measures. However, in addition to the pre-earthquake and post-earthquake alleviation actions, the scientific community indeed ...

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

open access: yesГеодинамика 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,
