Microtremor array observation in Southern Part of the Bandung basin: deep 1d s-wave velocity structure [PDF]

E3S Web of Conferences, 2023
Site amplification factor become crucial in seismic hazard microzonation, which depends on local geological condition, therefore identification of bedrock depth is very important related to sediment thickness.

Detection of hidden faults within the Fucino basin from single-station ambient noise measurements: The case study of the Trasacco fault system

Frontiers in Earth Science, 2022
The presence of normal fault systems in central Italy, outcropping or hidden below Quaternary covers in intra-mountain basins, is the expression of the Neogene–Quaternary evolution of the area, characterized by an extensional tectonic regime following ...

Seismic vulnerability analysis of steel buildings in Bogotá, Colombia [PDF]

, 2012
A number of mid-height steel buildings have been erected recently in Bogotá. Their seismic risk might be high, given the new microzonation of Bogotá and the lack of previous studies; remarkably, the response reduction factors were commonly obtained from ...

Comparing observed damages and losses with modelled ones using a probabilistic approach: the Lorca 2011 case [PDF]

, 2016
A loss and damage assessment was performed for the buildings of Lorca, Spain, considering an earthquake hazard scenario with similar characteristics to those of a real event which occurred on May 11th, 2011, in terms of epicentre, depth and magnitude ...

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

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 ...

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.
