Impact of Earthquake Hazard on Various Structures-A Case Study in Myanmar. [PDF]

ScientificWorldJournal
Natural disasters cannot be prevented, but it may be possible to reduce their impact on infrastructure by following some guidelines. This study evaluated earthquake‐induced damage (from the March 28, 2025 event in Myanmar) to infrastructure (i.e., reinforced concrete [RC], masonry, and temples) through field investigations and fragility analysis.

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.

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

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.

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.

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 microzoning in Skopje, Macedonia [PDF]

Soil Dynamics and Earthquake Engineering, 2017
Seismic microzonation maps for Skopje (Macedonia) are presented based on the Uniform-Hazard-Spectrum (UHS) methodology. UHS satisfies the guidelines for performance-based design (PBD), which require specification of two sets of spectral amplitudes, one for which the structure will remain essentially linear, and the other for which it will undergo 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.
