Earthquake Early Warning Starting From 3 s of Records on a Single Station With Machine Learning

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 11, November 2023., 2023
Abstract We introduce the Ensemble Earthquake Early Warning System (E3WS), a set of Machine Learning (ML) algorithms designed to detect, locate, and estimate the magnitude of an earthquake starting from 3 s of P‐waves recorded by a single station. The system is made of six Ensemble ML algorithms trained on attributes computed from ground acceleration ...

Toward earthquake early warning: A convolutional neural network for rapid earthquake magnitude estimation

Artificial Intelligence in Geosciences, 2023
Earthquake early warning (EEW) is one of the important tools to reduce the hazard of earthquakes. In contemporary seismology, EEW is typically transformed into a fast classification of earthquake magnitude, i.e., large magnitude earthquakes that require ...

Rapid Source Characterization of the Maule Earthquake Using Prompt Elasto‐Gravity Signals

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 9, September 2023., 2023
Abstract The recently identified Prompt Elasto‐Gravity Signals (PEGS), generated by large earthquakes, propagate at the speed of light and are sensitive to the earthquake magnitude and focal mechanism. These characteristics make PEGS potentially very advantageous for tsunami early warning, which relies on fast and accurate estimation of the magnitude ...

Earthquake Magnitude With DAS: A Transferable Data‐Based Scaling Relation

Geophysical Research Letters, Volume 50, Issue 10, 28 May 2023., 2023
Abstract Distributed Acoustic Sensing (DAS) is a promising technique to improve the rapid detection and characterization of earthquakes. Previous DAS studies mainly focus on the phase information but less on the amplitude information. In this study, we compile earthquake data from two DAS arrays in California, USA, and one submarine array in Sanriku ...

Understanding the social aspects of earthquake early warning: A literature review

Frontiers in Communication, 2022
Earthquake early warning (EEW) systems aim to warn end-users of incoming ground shaking from earthquakes that have ruptured further afield, potentially reducing risks to lives and properties. EEW is a socio-technical system involving technical and social

A framework to quantify the effectiveness of earthquake early warning in mitigating seismic risk

Earthquake Spectra, Volume 39, Issue 2, Page 938-961, May 2023., 2023
Earthquake early warning systems (EEWSs) aim to rapidly detect earthquakes and provide timely alerts, so that users can take protective actions prior to the onset of strong ground shaking. The promise and limitations of EEWSs have both been widely debated. On one hand, an operational EEWS could mitigate earthquake damage by triggering potentially cost‐

Stable operation process of earthquake early warning system based on machine learning: trial test and management perspective

Frontiers in Earth Science, 2023
Earthquake Early Warning (EEW) is an alert system, based on seismic wave propagation theory, to reduce human casualties. EEW systems mainly utilize technologies through both network-based and on-site methods.
