A Hybrid Deep Learning‐Based Forecasting Model for the Peak Height of Ionospheric F2 Layer

open access: yesSpace Weather, Volume 21, Issue 10, October 2023., 2023
Abstract To achieve accurate forecasting of the peak height of the ionospheric F2 layer (hmF2), we propose a hybrid deep learning model of improved seagull optimization algorithm (ISOA) optimized long short‐term memory (LSTM) model based on a complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) theory.

Locating Seismo-Conductivity Anomaly before the 2017 MW 6.5 Jiuzhaigou Earthquake in China Using Far Magnetic Stations

open access: yesRemote Sensing, 2020
Changes in the underlying conductivity around hypocenters are generally considered one of the promising mechanisms of seismo-electromagnetic anomaly generation. Parkinson vectors are indicators of high-conductivity materials and were utilized to remotely

Magnetic effects due to earthquakes and underground explosions: a review

open access: yesAnnals of Geophysics, 1997
The physical nature of quasi-static and transient anomalies in the geomagnetic field induced by underground explosions or earthquakes is reviewed. New theoretical results obtained recently and so far little known to general circles of geophysicists are ...

Influence of Lightning on the Observation of Seismic Electromagnetic Wave Anomalies

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2007
For two decades, many researchers have been claiming that pre-seismic electromagnetic phenomena may be useful in short-term earthquake prediction. Despite much effort, however, the relationship between anomalous electromagnetic signals and earthquakes ...

Laboratory investigation of coupled electrical interaction of fracturing rock with gases

open access: yesEarth, Planets and Space, 2021
In the coupled electric interaction of rock fractures and gas invasion, that is, when gases interact with newly created crack surfaces, the unpaired electrons within the rock crystal defects are thermally stimulated, released into the crack due to the ...
