Peak ground acceleration estimation using P-wave parameters and horizontal-to-vertical spectral ratios

Terrestrial, Atmospheric and Oceanic Sciences, 2020
Peak ground acceleration (PGA) can be used to estimate the seismic intensity. However, using P-wave features to estimate PGA is a challenging task. One of the reasons for that is that a seismic wave commonly undergoes modification due to various site ...
