Optimization of Network-Based Earthquake Early Warning Systems on the Korean Peninsula

IEEE Access, 2022
Most countries and local governments provide earthquake services in the public domain, and they must have high accuracy. If a missed alarm of the Earthquake Early Warning (EEW) system causes many casualties, or if the industrial system is temporarily ...

An All‐In‐One Rapid Prediction of Ground Motion Intensity Measures Hybrid Network for Multi‐Task in the North‐South Seismic Belt of China

Earth and Space Science, Volume 11, Issue 10, October 2024.
Abstract The north‐south seismic belt of China poses a high risk of earthquakes, necessitating the need for accurate and rapid prediction of intensity measures (IMs) to prevent and mitigate potential damage. We have developed a new multi‐task model, CRAQuake, to predict IMs for the north‐south seismic belt of China.

Investigating the cross-disciplinary components of earthquake early warning systems [PDF]

, 2021
Earthquake early warning (EEW) systems typically provide early estimates of earthquake magnitude, hypocentre location and/or ground-shaking estimates, as well as alerts ranging from a few seconds to tens of seconds, before the arrival of the damaging ...

Developing, Testing, and Communicating Earthquake Forecasts: Current Practices and Future Directions

Reviews of Geophysics, Volume 62, Issue 3, September 2024.
Abstract While deterministically predicting the time and location of earthquakes remains impossible, earthquake forecasting models can provide estimates of the probabilities of earthquakes occurring within some region over time. To enable informed decision‐making of civil protection, governmental agencies, or the public, Operational Earthquake ...

GRAPES: Earthquake Early Warning by Passing Seismic Vectors Through the Grapevine

Geophysical Research Letters, Volume 51, Issue 9, 16 May 2024.
Abstract Estimating an earthquake's magnitude and location may not be necessary to predict shaking in real time; instead, wavefield‐based approaches predict shaking with few assumptions about the seismic source. Here, we introduce GRAph Prediction of Earthquake Shaking (GRAPES), a deep learning model trained to characterize and propagate earthquake ...

A loss-based control algorithm for magnetorheological dampers combined with earthquake early warning [PDF]

, 2020
This paper presents a methodology that combines the use of magnetorheological (MR) dampers together with an earthquake early warning (EEW) system to minimize the losses in a structure about to be struck by an incoming ground motion.
