Definition of seismic and tsunami hazard scenarios by exploiting EU-India Grid e-infrastructures [PDF]

, 2012
Seismic hazard assessment can be performed following a neo-deterministic approach (NDSHA), which allows to give a realistic description of the seismic ground motion due to an earthquake of given distance and magnitude.

Dual-proxy estimation of Vs30: the case study of the Marche Region (central Italy)

Journal of Maps
This study focuses on generating a shear-wave velocity averaged within the uppermost 30 m of the ground surface (Vs30) map for the Marche region (central Italy) using two commonly acknowledged proxies: topographic slope and lithological classification ...

National‐scale Mapping of the Expected Earthquake Magnitude for Soil Liquefaction Triggering Analyses in Italy

Earthquake Spectra, Volume 42, Issue 1, February 2026.
This paper introduces a procedure to estimate moment magnitude (MW) in earthquake‐induced soil liquefaction probabilistic risk assessment. The method is based on using the historical seismicity modelled with a truncated Gutenberg‐Richter (G‐R) relation, jointly with an empirical model linking the MW to the maximum source‐to‐site distance at which soil ...

Twenty‐Five Years of Probabilistic Fault Displacement Hazard Assessment

Reviews of Geophysics, Volume 63, Issue 3, September 2025.
Abstract Fault displacement hazard poses significant risks to critical infrastructure such as buildings, roads, and pipelines. While some structures can tolerate a certain degree of surface displacement, others, such as buildings, are far more vulnerable. Probabilistic Fault Displacement Hazard Assessment (PFDHA) quantifies the probability of exceeding

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 ...
