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

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2618-2633, September 2026.ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such

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 ...

Seismic microzonation of Bangalore, India
Journal of Earth System Science, 2008 In the present study, an attempt has been made to evaluate the seismic hazard considering local site effects by carrying out detailed geotechnical and geophysical site characterization in Bangalore, India to develop microzonation maps. An area of 220 km2, encompassing Bangalore Mahanagara Palike (BMP) has been chosen as the study area.

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 ...
