Fault System-Based Probabilistic Seismic Hazard Assessment of a Moderate Seismicity Region: The Eastern Betics Shear Zone (SE Spain)

open access: yesFrontiers in Earth Science, 2020
Including faults as seismogenic sources in probabilistic seismic hazard assessments (PSHA) has turned into a common practice as knowledge of active faults is improving.

Earthquake and Tsunami NaTech Risk Assessment for Oil Storage Facilities

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1887-1904, 25 July 2026.
ABSTRACT Interaction of natural and technological hazards (NaTech) events, such as tsunamis and earthquakes, can affect industrial facilities such as those featuring anchored atmospheric storage tanks. Consequences of natural events on this kind of installation may include the release of hazardous substances, which in turn can lead to industrial ...

A Multivariate Mixed‐Effects Regression Framework for Ground Motion Modeling: Integrating Parametric and Machine Learning Approaches

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1811-1827, 25 July 2026.
ABSTRACT Multivariate ground motion models (GMMs) that capture the correlation between different intensity measures (IMs) are essential for seismic risk assessment. Conventional GMMs are often developed using a two‐stage approach, where separate univariate models with predefined functional forms are fitted first, and correlation is addressed in a ...

SIMULATION-BASED PSHA FOR THE KATHMANDU VALLEY: SENSITIVITY TO HYPOCENTRE RANDOMISATION

open access: yes, 2020
This paper presents a sensitivity study of simulation-based Probabilistic Seismic Hazard Analysis (PSHA) for Kathmandu, Nepal. Two aspects are investigated in detail: (i) the technique for simulating fault ruptures compatible with scaling laws and fitting into the Main Himalayan Trust (MHT) and (ii) the choice of different Ground Motion Prediction ...

Subduction Parameters Controlling the Occurrence of Shallow and Deep Slow‐Slip Events (SSEs)

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Slow‐slip events (SSEs) are transient aseismic fault‐slip phenomena that release tectonic stresses in a variety of tectonic environments, including subduction zones. In subduction margins, SSEs commonly occur along the plate interface at shallow (<20 km) and deep (30–60 km) depths.

The Purpose and Definition of the Minimum Magnitude Limit in PSHA Calculations [PDF]

open access: yesSeismological Research Letters, 2017
ABSTRACT A lower limit of magnitude M min is routinely defined for integrations of earthquake scenarios in probabilistic seismic‐hazard analysis but there is widespread misunderstanding of the technical bases for determining the value of this parameter.

Natural Climate Solutions, Indigenous Peoples, Mestizos, and the Legacies of Conflict Over Land in the Ecuadorian Amazon

open access: yesRural Sociology, Volume 91, Issue 2, June 2026.
ABSTRACT Over the past two decades as global alarm over disruptive climate change has grown, coalitions of high‐ranking government officials and prominent activists have launched campaigns to protect and restore greenhouse gas absorbing rain forests. The initial results from these campaigns have varied dramatically across racial and ethnic landholding ...

Seismic hazard assessment for the Sofia area

open access: yesAnnals of Geophysics, 2001
The capital of Bulgaria, Sofia, is situated in the center of the so-called Sofia area. This is the most populated industrial and cultural region of Bulgaria that faces considerable earthquake risk.

Regional Adjustments to NGA‐West2 Ground‐Motion Models for Turkey

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1313-1332, May 2026.
ABSTRACT This paper presents a ground‐motion model updating (GMMU) framework to adjust NGA‐West2 models for predicting a set of intensity measures in Turkey, including peak ground acceleration (PGA), peak ground velocity (PGV), and pseudo‐spectral acceleration (PSA) at periods ranging from 0.01 to 10 s. The GMMU framework integrates bias identification

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

open access: yesEarthquake 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
