The effect of alternative seismotectonic models on PSHA results – a sensitivity study for two sites in Israel [PDF]

Natural Hazards and Earth System Sciences, 2018
We present a full probabilistic seismic hazard analysis (PSHA) sensitivity analysis for two sites in southern Israel – one in the near field of a major fault system and one farther away.

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.

Selection of appropriate intensity measure for collapse capacity prediction of low to mid-rise steel special moment resisting frames [PDF]

Journal of Structural and Construction Engineering, 2017
A parameter that quantitatively represents the strength of a ground motion is called Intensity Measure (IM). The value of an IM for a given hazard level is the output parameter of Probabilistic Seismic Hazard Analysis (PSHA) which is used in structural ...

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

Uncertainty in PSHA related to the parametrization of historical intensity data [PDF]

Natural Hazards and Earth System Sciences, 2014
In recent times a great deal of research aimed to reduce of uncertainties in probabilistic seismic hazard analysis (PSHA). Most attention was paid to the role of ground motion prediction equations (GMPEs; see, e.g., Strasser et al., 2009), while no ...

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.

Probabilistic Seismic Hazard Analysis Incorporating Monte Carlo Method in the Case of Adelaide Region

Indonesian Journal on Geoscience, 2017
DOI: 10.17014/ijog.4.2.81-96A topic of seismic hazard analysis (SHA) is briefly elaborated. A probabilistic seismic hazard analysis (PSHA) is commonly used to assess the ground motion level expected with different likelihood at a rock site during a ...

Seismic Rigoletto: Hazards, risks and seismic roulette applications

Frontiers in Earth Science, 2023
Neo-Deterministic Seismic Hazard Assessment (NDSHA), dating back to the turn of the Millennium, is the new multi-disciplinary scenario- and physics-based approach for the evaluation of seismic hazard and safety–guaranteeing “prevention rather than cure.”
