A combined method for high-speed rail seismic monitoring and early warning
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
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 ...

Automatic earthquake confirmation for early warning system [PDF]
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),

Population response to earthquakes and earthquake early warnings in Mexico
Human responses to various natural hazards have been studied for more than a few decades. However, the effects of early warning interventions that alert the population to allow them time to take protective actions are not well known, at least to an extent where it could be compared within a socio-culturally similar region under two different scenarios:

Damping modification factors for acceleration response spectra
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 ...
