Practical limitations of earthquake early warning
Earthquake spectra, 2020 Earthquake early warning (EEW) entails detection of initial earthquake shaking and rapid estimation and notification to users prior to imminent, stronger shaking. EEW (ShakeAlert Phase 1, version 2.0) went operational in California in October 2019 and is

STUDY ON SITE CONDITIONS BASED ON TOPOGRAPHIC SLOPE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 The travel-time averaged shear-wave velocity to a depth of 30m (Vs30) below the Earth’s surface is widely used to classify sites in many building codes. Vs30 is also used to estimate site classification in recent ground-motion prediction equations (GMPEs)
