Estimation of historical earthquake‐induced liquefaction in Fraser River delta using NBCC 2020 GMPEs in deterministic and probabilistic frameworks

Earthquake Spectra, Volume 39, Issue 4, Page 2584-2612, November 2023., 2023
Paleo‐liquefaction features of sand dykes and sand blows were identified in the 1990s at multiple host sediments in the Fraser River delta in southern British Columbia all younger than 3500 BP. These paleo‐liquefaction sites could be linked to Cascadia subduction earthquakes.

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

Earthquake 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 “

Fuzzy Clustering Analysis of HVSR Data for Seismic Microzonation at Lahore City

Shock and Vibration, 2022
A microzonation study deals with the classification of hazards in a town or city in terms of surface ground motions that result from amplification and resonance frequency in soils against seismic tremors. This paper presents the result of a microzonation

Seismic microzonation of Mashhad city, northeast Iran

Annals of Geophysics, 2011
Mashhad city has a substantial risk of earthquakes due to the potential of the underlying soft soils to amplify ground motions. It is therefore imperative to conduct detailed seismic hazard assessment of the area (seismic microzonation).
