Regional zonation based on seismic vulnerability using local site effect analysis and potential damage to the city of Medan (North Sumatra, Indonesia) due to earthquake

Geoenvironmental Disasters, 2022
Background Microzonation becomes important for big cities like Medan (North Sumatra, Indonesia) as population agglomeration increases in urban areas resulting in rapid and unplanned construction.

Reconstructing Late Quaternary Paleovalley Systems of Italy Through mHVSR: A Tool for Seismic Hazard Assessment in Modern Coastal Lowlands

Earth and Space Science, Volume 10, Issue 12, December 2023., 2023
Abstract Effective site characterization in highly urbanized coastal lowlands requires accurate stratigraphic and geophysical investigations. In these regions, which typically host shallowly buried paleovalley systems formed in response to Quaternary glacio‐eustatic fluctuations, the marked lithologic contrast between soft sediment paleovalley fills ...

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.

Extensive surface geophysical prospecting for seismic microzonation

, 2020
This paper presents an overview of the geophysical activities for the seismic microzonation of 138 municipalities belonging to four Italian regions (Abruzzo, Lazio, Marche and Umbria) that were severely damaged by the seismic sequence of Central Italy ...

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 “

Seismic hazard mapping of Ohrid, North Macedonia

Earthquake Engineering and Resilience, Volume 2, Issue 1, Page 111-130, March 2023., 2023
A seismic microzonation study is presented for the city of Ohrid in North Macedonia, an important World Heritage Site, exceptionally rich in archeological, architectural, and cultural sites. The Uniform Hazard Method was used to compute the amplitudes of strong motion, with explicit consideration of the geological site conditions.

Innovative Seismic Microzonation Maps of Urban Areas for the Management of Building Heritage: A Catania Case Study

Geosciences, 2020
Several urban areas in the Mediterranean have already been subjected to seismic microzonation studies aimed at determining the acceleration expected on the ground surface, therefore mitigating the associated seismic risks.

Probabilistic approach for seismic microzonation integrating 3D geological and geotechnical uncertainty

Earthquake Spectra, Volume 39, Issue 1, Page 310-334, February 2023., 2023
A novel probabilistic methodology for regional seismic site characterization is proposed and applied to a region with highly heterogeneous surficial geology and varying soil sediment thickness and stiffness. The method combines various sources of geological and geotechnical uncertainties to develop a three‐dimensional (3D) shear‐wave velocity (Vs ...

Local site seismic response in an alpine valley: seismic microzonation of the Castel Caldes area (North-western Trentino) [PDF]

, 2022
The purpose of this work is to analyse the local-site seismic response in the Castel Caldes area, located in an alpine valley (Val di Sole) of the north-western Trentino region. The final result is the seismic microzonation map of this area.
