Geological and Historical‐Based Approaches to Define Scenario Earthquake: Case‐Studies and Application at Municipality‐Scale in Italy

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 15, Page 3828-3845, December 2025.
ABSTRACT This study compares two approaches for determining earthquake magnitude (M) and source‐to‐site distance (R) to assess seismic scenarios in Italy. The first method relies on geological criteria from the Italian seismogenic sources database (DISS3.3.0), while the second method uses historical earthquakes from the DBMI‐CPTI15 Italian catalogue ...

Range‐Parallel Extension of the Andes in the 2020 Mw 5.7 Humahuaca Earthquake

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Normal‐faulting earthquakes in mountain ranges provide important constraints on the dynamics of mountain building. To date, well‐documented examples of range‐parallel extension come primarily from the Tibetan Plateau, limiting our ability to test different models for its cause.

Seismic hazard assessment for the Sofia area

Annals 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.

Near-Field PSHA with Directivity – Dorud

Annals of Geophysics
This study investigates the probabilistic seismic hazard in Dorud city, located near the active Dorud fault, with a specific focus on incorporating near-field and rupture directivity effects into the hazard modeling framework. Near-field ground motions – particularly those influenced by rupture directivity – can generate long-period velocity pulses ...

LFW2BBP: Broadband Ground‐Motion Parameters Estimation Using Physics‐Based Simulated Low‐Frequency Waveforms and Deep Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Accurate prediction of broadband ground motion parameters is important for earthquake disaster prevention and mitigation. Due to the lack of high wave number components in the source rupture process and velocity models, physics‐based ground motion simulation methods can only reliably produce low‐frequency ground motions (< ${< } $1 Hz).

Seismic Risk Analysis of Revenue Losses, Gross Regional Product and transportation systems. [PDF]

, 2013
Natural threats like earthquakes, hurricanes or tsunamis have shown seri- ous impacts on communities. In the past, major earthquakes in the United States like Loma Prieta 1989, Northridge 1994, or recent events in Italy like L’Aquila 2009 or Emilia 2012 ...

Insights into temporal earthquake clustering from the Settlement Fault, southeastern Otago, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 747-772, December 2025.
ABSTRACT We combine previous studies, fieldwork, lidar data, and trenching to examine late Quaternary activity of the SE‐dipping ≥23 km long Settlement Fault in the southeastern South Island. Trenching of a scarp crossing a small alluvial fan exposed a > 3 m thick sequence of folded sandy to silty fan alluvium.

Development of an open-source platform for calculating losses from earthquakes [PDF]

, 2012
Risk analysis has a critical role in the reduction of casualties and damages due to earthquakes. Recognition of this relation has led to a rapid rise in demand for accurate, reliable and flexible risk assessment numerical tools and software.

Comparative Study of Seismic Hazard Analysis Using Classical PSHA and PSHA Method in Java Island, Indonesia

Indonesian Journal on Geoscience
In general, seismic hazard analysis is conducted using a probabilistic approach (PSHA), whilst seismic risk analysis is computed using a stochastic approach. To figur out more differences between the two methods, a comparative study of those two approaches needs to be conducted.

Supershear Rupture of the 1995 Mw ${M}_{\mathbf{w}}$ 7.2 Multi‐Segment Nuweiba Earthquake in the Gulf of Aqaba

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The Gulf of Aqaba (GoA) is the seismically most active region in the Red Sea, with a history of large earthquakes and posing a high seismic hazard to coastal communities. This study uses back‐projection and dynamic rupture simulation to investigate the largest instrumentally recorded earthquake in the GoA, the 1995 Mw ${M}_{\mathrm{w}}$ 7.2 ...
