Spectral acceleration basin amplification factors for interface Cascadia Subduction Zone earthquakes in Canada’s 2020 national seismic hazard model

open access: yesEarthquake Spectra, Volume 39, Issue 2, Page 1166-1188, May 2023., 2023
Canada’s 2020 national seismic hazard model (CSHM 2020) provides hazard estimates for interface Cascadia Subduction Zone (CSZ) earthquakes in southwestern Canada using four ground motion models (GMMs) with equal weights. Two out of the four GMMs were derived using data primarily from subduction earthquakes in Japan so their use in CSHM 2020 includes a “

Microzonation Study Based on Ground Amplification for Erzincan City

open access: yesDoğal Afetler ve Çevre Dergisi, 2019
Nearly all regions in Erzincan lie on a first degree earthquake zone. In the plains of the city, the thickness of the alluvial layer over the bedrock is about 1 km. In this regard, it is clear that a detailed ground amplification analysis is required for

Combining Earthquake Ground Motion and Ambient Vibration Recordings to Evaluate a Local High-Resolution Amplification Model—Insight From the Lucerne Area, Switzerland

open access: yesFrontiers in Earth Science, 2022
Amplification factors are often estimated using empirical methods based on earthquake ground motion; however, especially in low-seismicity urban areas, recording a statistically representative number of high-quality signals may take years.

Evaluating the Minimum Number of Earthquakes in Empirical Site Response Assessment: Input for New Requirements for Microzonation in the Swiss Building Codes

open access: yesFrontiers in Earth Science, 2022
Site-specific hazard analyses and microzonation are important products for densely populated areas and facilities of special risk. The empirical amplification function is classically estimated using the standard spectral ratio (SSR) approach.
