A combined method for high-speed rail seismic monitoring and early warning
Geodesy and Geodynamics, 2017 The ground motion characteristics include the strength, frequency spectrum and duration time. In China, the PGA (peak ground acceleration) is commonly used in determination of whether an earthquake warning is necessary when the high-speed train is on the

Correlation of the slope of the initial part of P-wave envelope, hypocenter depth and plate boundary
Geodesy and Geodynamics, 2018 We investigated correlation of the slope of the initial part of P-wave envelope, hypocenter depth and plate boundaries by B-Δ method, which is used to determine epicentral distances in the Japan Meteorological Agency and Japan Railway Company earthquake ...

Crowd-Funded Earthquake Early-Warning System
2022 International Conference on Computational Science and Computational Intelligence (CSCI), 2022 Earthquake early warning systems has been proven to save countless lives in Japan, Mexico, and Chile, where earthquake warnings are often broadcast live on TV up to a minute before residents experience shaking. Unfortunately, traditional early warning systems require extensive capital investment.

Automatic earthquake confirmation for early warning system [PDF]
Geophysical Research Letters, 2015 AbstractEarthquake early warning studies are shifting real‐time seismology in earthquake science. They provide methods to rapidly assess earthquakes to predict damaging ground shaking. Preventing false alarms from these systems is key. Here we developed a simple, robust algorithm, Authorizing GRound shaking for Earthquake Early warning Systems (AGREEs),

Damping modification factors for acceleration response spectra
Geodesy and Geodynamics, 2017 DMF (Damping modification factors) are used to modify elastic response spectral values corresponding to damping ratio 5% to other damping levels. The influence of seismological parameters (magnitude, epicentral distances and site conditions) on DMF for ...
