Migratory earthquake precursors are dominant on an ice stream fault. [PDF]

Sci Adv, 2021
Migratory nucleation of earthquakes is dominant, and self-nucleation is rare over many repeats of a natural stick-slip cycle. Simple fault models predict earthquake nucleation near the eventual hypocenter (self-nucleation). However, some earthquakes have

Acoustic Energy Release During the Laboratory Seismic Cycle: Insights on Laboratory Earthquake Precursors and Prediction. [PDF]

J Geophys Res Solid Earth, 2020
Machine learning can predict the timing and magnitude of laboratory earthquakes using statistics of acoustic emissions. The evolution of acoustic energy is critical for lab earthquake prediction; however, the connections between acoustic energy and fault

Investigating short-term earthquake precursors detection through monitoring of total electron content variation in ionosphere

Frontiers in Astronomy and Space Sciences, 2023
The effectiveness and accuracy of earthquake precursors are measured by the ability of the precursors to predict the time, epicentral distance, and magnitude of the earthquake for short-term earthquake prediction.

Geological and Geophysical Factors Constraining the Occurrence of Earthquake Precursors in Geofluids: A Review and Reinterpretation

Frontiers in Earth Science, 2020
In this paper, we update the previous compilations of observed earthquake precursors from the published scientific literature of the last decade. We collected the epicentral coordinates, magnitude, hypocentral depth of each earthquake and the distance ...

Deep Machine Learning Based Possible Atmospheric and Ionospheric Precursors of the 2021 Mw 7.1 Japan Earthquake

Remote Sensing, 2023
Global Navigation Satellite System (GNSS)- and Remote Sensing (RS)-based Earth observations have a significant approach on the monitoring of natural disasters. Since the evolution and appearance of earthquake precursors exhibit complex behavior, the need

Electromagnetic and Radon Earthquake Precursors

Geosciences
Earthquake forecasting is arguably one of the most challenging tasks in Earth sciences owing to the high complexity of the earthquake process. Over the past 40 years, there has been a plethora of work on finding credible, consistent and accurate ...

A Critical Review of Ground Based Observations of Earthquake Precursors

Frontiers in Earth Science, 2021
We aim at giving a short review of the seismo-associated phenomena detected on ground that in recent years have been investigated as possible earthquake precursors.

Regional Seismic Information Entropy to Detect Earthquake Activation Precursors

Entropy, 2018
A method is presented to detect earthquake precursors from time series data on earthquakes in a target region. The Regional Entropy of Seismic Information (RESI) is an index that represents the average influence of an earthquake in a target region on the
