Real-Data Testing of Distributed Acoustic Sensing for Offshore Earthquake Early Warning

The Seismic Record, 2023
We present a real-data test for offshore earthquake early warning (EEW) with distributed acoustic sensing (DAS) by transforming submarine fiber-optic cable into a dense seismic array.

A judgement method for earthquake early warning information

, 2012
Earthquake early warning (EEW) is very important to earthquake mitigation, but EEW information before an earthquake is usually ignored. China Public Safety Early Warning Information Systems (CPSEWIS) including EEW information before, amid and after an ...

Reducing Latencies in Earthquake Early Warning [PDF]

, 2018
Existing Earthquake Early Warning (EEW) algorithms use waveform analysis for earthquake detections, estimation of source parameters (i.e., magnitude and hypocenter location), and prediction of peak ground motions at sites near the source.

Performance-Based Earthquake Early Warning

, 2011
Significant investments are undergoing internationally to develop earthquake early warning (EEW) systems. So far, reasonably, the most of the research in this field was lead by seismologists as the issues to determine essential feasibility of EEW were ...

User Acceptance and Perceptions of Earthquake Early Warning Systems as a Function of Information Type: The Case of Postearthquake Nepal

Earthquake Spectra, Volume 42, Issue 2, May 2026.
What drives user perceptions and acceptance of earthquake early warning systems (EEWS) as an emerging technology? Do distinct types of transparency into EEWS affect users’ perceptions of the system's usefulness and desirability differently? To address these questions, we focus on Nepal, an earthquake‐prone country with no active public EEWS ...

From Warnings to Actions: Factors Influencing Response to Earthquake Early Warning—A Systematic Literature Review

Earthquake Spectra, Volume 42, Issue 2, May 2026.
Earthquake early warning (EEW) systems offer critical seconds for protective actions, yet their effectiveness ultimately depends on human interpretation and response. This article presents a systematic literature review of factors shaping public behavior during earthquakes and in response to EEW alerts.

Analysis of dynamic path loss based on the RSSI model for rupture location analysis in underground wireless sensor networks and its implications for Earthquake Early Warning System (EEWS)

International Journal of Automation and Smart Technology, 2015
Sensors deployed in underground tunnels found that radio frequency signals suffer significant signal strength attenuation which can result in considerable variation of link quality on the receiving end. This study analyzes the received signal strength index (RSSI) based on  the development of a theoretical wireless sensor model for  data  collection by

Whether and When Large Earthquake Magnitudes Can Be Determined From Rupture Onsets

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Whether and when earthquakes of different sizes can be distinguished early in their rupture process is critical to improving earthquake early warning (EEW) systems. To address this question, we develop a transformer‐based framework called source time function Magnitude Network (STF‐MgNet), which leverages earthquake STFs with Mw ≥ ${\ge} $ 5.5
