Softening and Recovery of Near‐Surface Layers During the 2024 M7.6 Noto Earthquake

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract On 1 January 2024, a devastating MJ 7.6 earthquake occurred on the Noto Peninsula in Japan. When such a strong earthquake occurs, affected near‐surface soil layers behave nonlinearly and may undergo some structural changes driven by Flow Liquefaction, Cyclic Mobility, or Slow Dynamics phenomena.

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 ...

Integration of HVSR measures and stratigraphic constraints for seismic microzonation studies: the case of Oliveri (ME) [PDF]

, 2014
Because of its high seismic hazard the urban area of Oliveri has been subject of first level seismic microzonation. The town develops on a large coastal plain made of mixed fluvial/marine sediments, overlapping a complexly deformed substrate. In order to

Seismic microzonation and soil-structure resonance analysis in Suryabinayak Municipality, Bhaktapur, Nepal: insights from ambient vibration measurements

Geomatics, Natural Hazards & Risk
Bhaktapur, lying in the Kathmandu Basin, suffered damages during the 2015 Gorkha Earthquake, potentially exacerbated by local site effects. This research addresses the lack of site response study on Suryabinayak Municipality, located in the southern part
