An Improved Pattern Informatics Method for Extracting Ionospheric Disturbances Related to Seismicity Based on CSES Data: A Case Study of the Mw7.3 Maduo Earthquake

Earth and Space Science, Volume 11, Issue 12, December 2024.
Abstract The exploration of multi‐layer coupling mechanisms between earthquakes and the ionosphere is crucial for utilizing ionospheric precursors in earthquake prediction. A significant research task involves continuously tracking the spatio‐temporal changes in ionospheric parameters, acquiring comprehensive seismic anomaly information, and capturing “

The Double Peak Superposition on the Equatorial Ionization Anomaly Crests During the 23 April 2023 Storm

Geophysical Research Letters, Volume 51, Issue 22, 28 November 2024.
Abstract The typical equatorial ionization anomaly (EIA) exhibits two crests around the magnetic equator. Here we reported evidence for a double‐peak superposition at the EIA crest of each hemisphere, forming a four‐peak structure, with the additional peaks located ∼10° poleward of normal crests, as observed by CSES at 500 km altitudes on dayside ...

Near‐Real‐Time Identification of the Source of Ionospheric Disturbances

Journal of Geophysical Research: Space Physics, Volume 129, Issue 11, November 2024.
Abstract The ionosphere is characterized by a large number of disturbances generated in response to a wide range of phenomena, including natural hazards, space weather and man‐made events. Identification of the origin of ionospheric disturbances (ID), especially in real or near‐real‐time (NRT), is an extremely difficult task, and it is one of the most ...

A Numerical Consideration on the Correlation Between Magnitude of Earthquakes and Current Intensity Causing ULF Electromagnetic Wave Emission

Radio Science, Volume 59, Issue 7, July 2024.
Abstract Numerous studies have reported anomalous ultralow frequency (ULF) electromagnetic fields preceding earthquakes. In this paper, we estimate the current intensity responsible for generating the earthquake‐related ULF fields under the assumption that the origin is a current flowing at the hypocenter and that it has the same frequency dependence ...

Empowering Machine Learning Forecasting of Labquake Using Event‐Based Features and Clustering Characteristics

Journal of Geophysical Research: Machine Learning and Computation, Volume 1, Issue 2, June 2024.
Abstract Following recent advances of machine learning (ML), we present a novel approach to extract spatiotemporal seismo‐mechanical features from Acoustic Emission (AE) catalogs to empower ML‐based forecasting. The AE data were recorded during laboratory stick‐slip experiments on granite samples cut by rough faults.
