Opportunities for the U.S. Geological Survey's National Seismic Hazard Model to Improve Seismic Risk Assessment of Critical Infrastructure

Earthquake Spectra, Volume 42, Issue 2, May 2026.
As fragility and risk modeling techniques and computational capabilities evolve, complemented by moving toward more routine and systematic seismic risk assessment of all buildings and critical infrastructure, the authors pose a few critical questions to investigate how the U.S. Geological Survey (USGS) National Seismic Hazard Models (NSHMs) can be used

Assessing Post‐Earthquake Emergency Healthcare Accessibility Considering Damage to Hospital Buildings and Transportation Infrastructure

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This article presents a framework for performing a regional assessment of the accessibility of emergency healthcare facilities after a major earthquake. Accessibility is assessed by applying the enhanced two‐step floating catchment area method to a regional road network, implemented in ArcGIS.

A Performance‐Based Earthquake Fatality Modeling Framework Using Collapse Volume Ratios

Earthquake Spectra, Volume 42, Issue 2, May 2026.
Conventional earthquake fatality models are commonly implemented using a binary representation of building collapse, an assumption that overlooks severe failure modes and systematically underestimates fatalities. To address this limitation, this study advances the collapse volume ratio—a continuous metric quantifying the reduction of survivable space ...

Earthquake Damage Repair Loss Estimation in New Zealand: What Other Variables Are Essential Based on Experts’ Opinions?

Buildings, 2021
Major earthquakes can cause extensive damage to buildings and alter both the natural and built environments. Accurately estimating the financial impact from these events is complex, and the damage is not always visible to the naked eye.

Time‐ and State‐Dependent Damage Accumulation Due to Aftershocks Under an M9.0 Megathrust Earthquake in the Cascadia Subduction Zone

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1157-1175, 25 April 2026.
ABSTRACT This study develops a comprehensive framework for assessing time and state‐dependent aftershock damage accumulation under an M9.0 megathrust interface earthquake in the Cascadia Subduction Zone (CSZ). The framework integrates aftershock probabilistic seismic hazard analysis (APSHA) and state‐dependent fragility analysis (SDFA) within a ...

Flood damage cost estimation in 3D based on an indicator modelling framework

Geomatics, Natural Hazards & Risk, 2020
Flooding and other natural disasters pose risks to cities and residential homes, and these are set to increase in the face of climate change. Single-family residential buildings are of particular interest because they are difficult to insure and often ...
