Evaluating Simplified Methods for Liquefaction Assessment for Loss Estimation [PDF]
, 2016 Currently, some catastrophe models used by the insurance industry account for liquefaction by applying a simple factor to shaking-induced losses. The factor is based only on local liquefaction susceptibility and this highlights the need for a more ...

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.Abstract Seismic faults are surrounded by damaged rocks with reduced rigidity and enhanced attenuation. These damaged fault zone structures can amplify seismic waves and affect earthquake dynamics, yet they are typically omitted in physics‐based regional ground motion simulations.

The Seismic RecordWe examine how the choice of ground-motion-to-intensity conversion equations (GMICEs) in earthquake early warning (EEW) systems affects resulting alert regions. We find that existing GMICEs can underestimate observed shaking at short rupture distances or

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract The M6.4 mainshock of the southwestern Puerto Rico seismic sequence on 7 January 2020, was one of the most impactful modern earthquakes in the northeastern Caribbean. Due to its offshore location and complex aftershock distribution, its source kinematics remain poorly constrained.

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 1, January 2025.Abstract Landslides occur where the stresses below the surface exceed the shear strength of the material. Landslide inventories thus offer opportunities to investigate patterns in subsurface strength provided that the stress conditions at failure can be estimated. Clues to the failure stresses are encoded in the inclination of the slope that failed and

Accounting for ground‐motion uncertainty in empirical seismic fragility modeling
Earthquake Spectra, Volume 40, Issue 4, Page 2456-2474, November 2024.Seismic fragility models provide a probabilistic relation between ground‐motion intensity and damage, making them a crucial component of many regional risk assessments. Estimating such models from damage data gathered after past earthquakes is challenging because of uncertainty in the ground‐motion intensity the structures were subjected to.

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 ...

The 2023 Alaska National Seismic Hazard Model
Earthquake Spectra, Volume 40, Issue 4, Page 2545-2597, November 2024.US Geological Survey (USGS) National Seismic Hazard Models (NSHMs) are used extensively for seismic design regulations in the United States and earthquake scenario development, as well as risk assessment and mitigation for both buildings and infrastructure.
