Impact assessment of earthquake early warning systems in Central America

Earthquake Spectra, Volume 41, Issue 4, Page 3094-3122, November 2025.
Earthquake Early Warning (EEW) systems aim to alert users in advance of imminent shaking, enabling them to take action. In collaboration with local seismic agencies, the Swiss Seismological Service (SED), has developed national EEW systems across Central America.

A Framework for Evaluating Earthquake Early Warning for an Infrastructure Network: An Idealized Case Study of a Northern California Rail System

Frontiers in Earth Science, 2021
Earthquake early warning (EEW) systems provide a few to tens of seconds of warning before shaking hits a site. Despite the recent rapid developments of EEW systems around the world, the optimal alert response strategy and the practical benefit of using ...

PEGSGraph: A Graph Neural Network for Fast Earthquake Characterization Based on Prompt ElastoGravity Signals

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 1, March 2025.
Abstract State‐of‐the‐art earthquake early warning systems use the early records of seismic waves to estimate the magnitude and location of the seismic source before the shaking and the tsunami strike. Because of the inherent properties of early seismic records, those systems systematically underestimate the magnitude of large events, which results in ...

Development of Earthquake Early Warning Systems in the European Union Early Warning for Geological Disasters

, 2014
Utilization of Earthquake Early Warning Systems (EEWS) in Europe is lagging significantly in respect of pioneer applications in Japan and Mexico. The first reported implementation of a EEWS in Europe is the on-site system designed to protect the Ignalina

Single Station Seismic Event Location With a Neural‐Guided Mixture Model: Model‐Based Weighting for Improved Accuracy

Journal of Geophysical Research: Machine Learning and Computation, Volume 1, Issue 4, December 2024.
Abstract In many regions of the world with complex seismic activity, the availability of seismic stations is limited. This motivated us to develop a probabilistic method for single‐station earthquake location. Single station location methods may provide an efficient and cost‐effective way to monitor small‐magnitude seismic events over large areas of ...
