Six‐Component Earthquake Synchronous Observations Across Taiwan Strait: Phase Velocity and Source Location

Earth and Space Science, Volume 10, Issue 12, December 2023., 2023
Abstract With the development of rotational seismometers, especially the high‐sensitivity optical seismometers, rotational motions have shown increasing benefits for calculation of dispersion curves, estimation of back azimuth and many other applications. Here we present the six‐component observations of 2019 Hualien mww6.1 earthquake simultaneously on

Local seismic hazard map based on the response spectra of stiff and very dense soils in Bengkulu city, Indonesia

Geodesy and Geodynamics, 2022
It is well known that seismic hazard assessment should be implemented to design infrastructures in an earthquake-prone area such as Bengkulu. This paper presents local seismic hazard maps based on the response spectra of stiff and very dense soils in ...

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 ...

Table1_Seismic microzonation mapping of Greater Vancouver based on various site classification metrics.DOCX [PDF]

, 2023
The goal of the multi-year seismic microzonation mapping project for Greater Vancouver, British Columbia, Canada, is to produce seismic hazard maps inclusive of local site effects, in particular seismic hazard specific to one-dimensional site response ...

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 “

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.

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

Sharing Soil and Building Geophysical Data for Seismic Characterization of Cities Using CLARA WebGIS: A Case Study of Matera (Southern Italy)

Applied Sciences, 2021
In the context of seismic risk, studying the characteristics of urban soils and of the built environment means adopting a holistic vision of the city, taking a step forward compared to the current microzonation approach.
