Seismic Microzonation Map of Chiang Mai Basin, Thailand

Trends in Sciences
The seismic site effect which is controlled by local geological conditions is a key parameter of seismic hazards analysis. This paper presents an observational study of microtremor data to investigate the dynamic characteristics of soil in the Chiang Mai basin (Chiang Mai and Lumphun province), Northern Thailand.

3D Shear‐Wave Velocity and Density Modeling of the Northern Cascadia Subduction Zone

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 3, March 2025.
Abstract In the Northern Cascadia Subduction Zone (NCSZ), we developed a new 3D model for shear‐wave velocity (VS) and density to improve seismic hazard assessments and ground motion simulations. Utilizing seismic data from the past two decades, we measure surface wave dispersion from ambient noise and earthquake recordings and inverted them for VS ...

Multimethod Geophysical Imaging of Intermontane Basins: The Case Study of Cascina and Palarzano Plains (Central Apennines, Italy)

International Journal of Geophysics, Volume 2025, Issue 1, 2025.
A novel and integrated geophysical approach has been applied at Cascina and Palarzano plains (Abruzzi region, Central Apennines, Italy) to investigate their subsurface structure with particular attention to the faults bounding the basins. Both plains are characterized by the highest magnetic anomaly intensity measured over the Abruzzi region (up to 10 ...

Update of the Seismic Microzonation Map of Lima and Callao, Peru

Journal of Disaster Research
Lima City and Callao Province are located in the Pacific Ring of Fire and have experienced major earthquakes over the years. To understand the seismic response of the soil, a seismic microzonation study was developed, taking into account the results of geological, geotechnical, and geophysical surveys.

Space–time finite element method with domain reduction techniques for dynamic soil–structure interaction problems

International Journal of Mechanical System Dynamics, Volume 4, Issue 2, Page 117-130, June 2024.
Abstract Design of earth structures, such as dams, tunnels, and embankments, against the vibrational loading caused by high‐speed trains, road traffic, underground explosions, and, more importantly, earthquake motion, demands solutions of the dynamic soil–structure Interaction (SSI) problem.

Preliminary seismic microzonation map of the City of Zagreb (Croatia)

Journal of Maps
The aim of this study was to create a preliminary seismic microzonation map of the administrative area of the City of Zagreb (Croatia). Geophysical measurements collected in the southern and eastern part of Zagreb were used together with geophysical data available for the northern part of the city. Their analysis and comparison with the geological data
