Strategies for comparison of modern probabilistic seismic hazard models and insights from the Germany and France border region [PDF]

Natural Hazards and Earth System Sciences
The latest generation of national and regional probabilistic seismic hazard assessments (PSHAs) in Europe presents stakeholders with multiple representations of the hazard in many regions.

Comparison of Seismic Performance Assessment Using Observed or Simulated Ground Motions in Seismic Hazard Analysis and Ground Motion Selection

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2449-2465, August 2026.
ABSTRACT This paper illustrates opportunities for the use of simulated ground motions in seismic performance assessment – from seismic hazard, ground‐motion selection, response history analysis, and seismic demand hazard calculation. The illustration is through a comparative analysis with the conventional alternative of observed ground motions.

Time-Dependent Seismic Hazard Analysis for Induced Seismicity: The Case of St Gallen (Switzerland), Geothermal Field

Energies, 2021
Reliable seismic hazard analyses are crucial to mitigate seismic risk. When dealing with induced seismicity the standard Probabilistic Seismic Hazard Analysis (PSHA) has to be modified because of the peculiar characteristics of the induced events.

Evaluating the U.S. Geological Survey's Earthquake Shaking Hazard Forecasts and Their Implications on Seismic Risk

Earthquake Spectra, Volume 42, Issue 3, August 2026.
We analyze the last six update cycles of the long‐term probabilistic earthquake shaking hazard forecast from the U.S. Geological Survey (USGS) and discuss the changes in hazard estimates from the 1996 to the latest 2023 update of the National Seismic Hazard Model (NSHM) for the conterminous United States.

Prostatic Stromal Hyperplasia with Atypia

Case Reports in Urology, 2013
Prostatic stromal hyperplasia with atypia (PSHA) is a rare histologic finding diagnosed incidentally on prostate biopsies, transurethral resection specimens, and radical prostatectomy specimens.

Nonstationary Spatial Correlation of Earthquake Ground Motions in California

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Assessing seismic risk to spatially distributed infrastructure systems requires realistic representations of spatially correlated ground motions. Existing models for the spatial correlations of ground motions rely on strong second‐order stationarity assumptions, under which the correlation structure is assumed to be invariant across space, potentially ...

Preliminary earthquake focal mechanism forecasts for the Amatrice sequence (central Italy)

Annals of Geophysics, 2016
We place the Amatrice (central Italy) seismic sequence and the related epicentral area in a contest of Probabilistic Seismic Hazard Analysis (PSHA). We apply a procedure to compute the probability to observe in the future a normal, reverse or strike-slip

The Influence of Fault Rupture Velocity on Ground Motions and Building Demands in the Near‐Fault Region

Earthquake Spectra, Volume 42, Issue 3, August 2026.
With the recent increases in measured ground motion records for large earthquakes, most notably the 2023 M7.8 Pazarcik earthquake in Türkiye, the potential for pervasive high velocity fault rupture propagation over an extensive fault length has been observed.

Demonstration of pb-PSHA with Ras-Elhekma earthquake, Egypt [PDF]

NRIAG Journal of Astronomy and Geophysics, 2017
Abstract The main goal of this work is to: (1) argue for the importance of a physically-based probabilistic seismic hazard analysis (pb-PSHA) methodology and show examples to support the argument from recent events, (2) demonstrate the methodology with the ground motion simulations of May 28, 1998, Mw = 5.5 Ras-Elhekma earthquake, north Egypt.

Quantifying Model Selection Uncertainty in Structural Analysis: Methodology and Application

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1828-1844, 25 July 2026.
ABSTRACT With increasing focus on complex engineering systems under rare events, computational models are critical for predictions due to the scarcity or absence of data. However, selecting an appropriate model can be challenging. Using a single model without available test calibration could result in significant bias in performance predictions. A case
