Interpreting intraplate tectonics for seismic hazard : a UK historical perspective [PDF]
, 2012 It is notoriously difficult to construct seismic source models for probabilistic seismic hazard assessment in intraplate areas on the basis of geological information, and many practitioners have given up the task in favour of purely seismicity-based ...

PSHA after a strong earthquake: hints for the recovery [PDF]
Annals of Geophysics, 2016 <p>We perform aftershock probabilistic seismic hazard analysis (APSHA) of the ongoing aftershock sequence following the Amatrice August 24th, 2016 Central Italy earthquake. APSHA is a time-dependent PSHA calculation where earthquake occurrence rates decrease after the occurrence of a mainshock following an Omori-type decay.

Integrating Long and Short‐Term Time Dependencies in Simulation‐Based Seismic Hazard Assessments
Earth and Space Science, 2022 Conventional probabilistic seismic hazard analysis (PSHA) only considers mainshock events and uses a time‐independent earthquake rupture forecast to describe the occurrence of mainshocks. This approach neglects the long‐term time‐dependency of mainshocks

PSHA Validated by Quasi Observational Means [PDF]
Seismological Research Letters, 2012 It might seem odd to be writing about confirmation of the validity of probabilistic seismic hazard assessment (PSHA) in 2011, given that the method has been successfully applied in countless studies worldwide over the last 40 years. However, the fact that papers still occasionally find their way into print attacking the method as mathematically invalid

Rudarsko-geološko-naftni Zbornik, 2021 Smoothed gridded seismicity is an analysis model in seismicity that allows for the obtaining of a rate based on the b-value and the same magnitude range. The data study has been collected and analyzed from a background source gathered by PusGen, referred

Application of Single-Station Sigma and Site-Response Characterization in a Probabilistic Seismic-Hazard Analysis for a New Nuclear Site [PDF]
, 2014 Aleatory variability in ground-motion prediction, represented by the standard deviation (sigma) of a ground-motion prediction equation, exerts a very strong influence on the results of probabilistic seismic-hazard analysis (PSHA).

Towards preparation of design spectra for Serbian national annex to Eurocode 8: Part II. Usage of the UHS approach instead of normalized spectral shapes scaled by a single PSHA parameter [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2012 Eurocode 8 spectra are scaled by the peak ground acceleration values that are defined for the given site through a probabilistic seismic hazard analyses (PSHA).

Geoenvironmental Disasters, 2021 Earthquake is a sudden release of energy due to faults. Natural calamities like earthquakes can neither be predicted nor prevented. However, the severity of the damages can be minimized by development of proper infrastructure which includes microzonation
