From 1980 to 2021, earthquakes have caused more than 846 000 casualties and about US
$661 billion in economic losses. At present, there are no reliable earthquake precursors to …

The observation of geomagnetic anomalies appearing prior to earthquakes (EQs) is
theorized to be generated by underground seismic processes. However, these pre EQ …

The ultralow-frequency (ULF) electromagnetic anomaly has been considered one of the
earthquake precursory signals with the potential for short-term prediction. As such …

Earthquake monitoring requires advanced instruments, such as a high-accuracy deep well
magnetometer. However, many challenges are encountered in harsh environments, such as …

Geomagnetic field data have been found to contain earthquake (EQ) precursory signals;
however, analyzing this high-resolution, imbalanced data presents challenges when …

High-sensitivity magnetic field measurements are crucial in modern geoscience exploration.
This study introduces an innovative free precession Bell–Bloom atomic magnetometer …

This paper focuses on the anomaly detection for ionospheric total electron content (TEC)
before earthquakes. In this paper, a novel unsupervised approach is proposed. First, interval …

The application of electromagnetic signals in earthquake study has been demonstrated by
previous researchers by monitoring the geomagnetic variations. This prospective study …

The conventional method of predicting earthquakes is based on historical seismic records of
earthquake-prone areas that can only provide probabilistic predictions. However, the …

The effectiveness and accuracy of earthquake precursors can be evaluated based on their
ability to determine the time, epicentral distance, and magnitude of the earthquake for short …
