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 ...

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 ...

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.

Earthquake Spectra, Volume 40, Issue 2, Page 1215-1234, May 2024.One‐dimensional (1D) site response analysis (SRA), which considers vertically propagating seismic waves from the bedrock to the surface, has been a common technique among geotechnical engineers to examine site‐specific ground shaking. However, observations from past earthquakes and analytical studies indicate that idealizations ingrained in 1D SRA may ...

State‐of‐the‐Art Seismic Studies of Loess Tunnels in China
Advances in Civil Engineering, Volume 2024, Issue 1, 2024.Large earthquakes occur frequently around the world. Due to the fragility of loess, the effects of seismic events on loess tunnel projects have received considerable in‐depth research attention. In this paper, we systematically review recent seismic research on loess tunnels and highlight deficiencies that require further study with a focus on the ...

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.Approximately 20,000 people are killed annually on average by building and infrastructure collapses and failures caused by seismic activities. In earlier times, seismic design codes and specifications set minimal requirements for life safety performance levels. Earthquakes can be thought of as recurring events in seismically active areas, with severity
