2025 U.S. Geological Survey National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands: Overview of Model and Hazard Results

Earthquake Spectra, Volume 42, Issue 2, May 2026.
The U.S. Geological Survey recently updated the National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). The first version of the PRVI NSHM was released in 2003, and therefore this 2025 update includes over 20 years of new geologic, geophysical, and engineering data, methods, and models.

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 ...

A Comparison of Ground Motion Intensity Measures for Estimating Collapse

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This study examines the use of 15 different intensity measures (IMs) for estimating structural collapse using results from incremental dynamic analysis (IDA). IDA results from 54 numerical models were considered, including (i) 12 reinforced concrete (RC) frame structures, (ii) 16 RC wall–frame structures and (iii) 26 steel buckling‐restrained braced ...

Validation of Physics‐Based Simulated Accelerograms for Seismic Fragility Analyses of Italian RC Existing Building Types

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This article aims at exploring and validating the use of 3D physics‐based simulated ground motions as seismic input for the derivation of seismic fragility curves based on nonlinear dynamic numerical analyses. Fragility curves are computed for a set of pre‐code (i.e., designed only for vertical loads), reinforced concrete building types representative ...

From Warnings to Actions: Factors Influencing Response to Earthquake Early Warning—A Systematic Literature Review

Earthquake Spectra, Volume 42, Issue 2, May 2026.
Earthquake early warning (EEW) systems offer critical seconds for protective actions, yet their effectiveness ultimately depends on human interpretation and response. This article presents a systematic literature review of factors shaping public behavior during earthquakes and in response to EEW alerts.
