New Constraints on Active Normal Faulting in the South Gulf of Evia, Greece: Geometry, Evolution, and Seismic Hazard of the South Coastal Fault System

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In many areas of active faulting, the continuity of normal faults with short or incomplete historical earthquake records and more subdued topographic expressions is not fully understood and consequently the seismic potential of these faults is often underestimated.

A Deep Learning Framework for Peak Ground Velocity Prediction Using Multi‐Station Velocity Waveforms: The Taiwan Transformer Shaking Alert Model (TT‐SAM)

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract This study proposes a deep‐learning–based regional earthquake early warning model, the Taiwan Transformer Shaking Alert Model (TT‐SAM). The model adopts peak ground velocity (PGV) as its primary ground shaking prediction unit, aiming to better reflect actual structural damage and thereby enhance the practical utility and accuracy of the ...

Intensity assignments from historical earthquake data: issues of certainty and quality

Annals of Geophysics, 1998
The use of macroseismic data in assessing parameters for historical earthquakes for use in seismic hazard assessment has thrown more attention on the way in which these data are treated.

USGS “Did You Feel It?”—Science and Lessons From 20 Years of Citizen Science-Based Macroseismology

Frontiers in Earth Science, 2020
The U.S. Geological Survey (USGS) “Did You Feel It?” (DYFI) system is an automatic method for rapidly collecting macroseismic intensity (MI) data from internet users’ shaking and damage reports and for generating intensity maps immediately following felt

Source Parameters of the 1906 Manas (Mw 7.7), 1944 Xinyuan (Mw 7.2) and 1812 Nilke Earthquakes and Seismotectonics of the Borohoro Shan, Western China

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The 1906 Manas Earthquake is the largest earthquake recorded in the Borohoro Shan (BRS) since 1900. The reported magnitude ranges from 7.2 to 8.3, but uncertainties remain regarding its size, mechanism, and responsible fault. Similar confusion exists for the 1812 Nilke and 1944 Xinyuan Earthquakes, the only other Mw > 7 earthquakes in the NE ...

In for a penny: An empirical study of earthquake experience and non‐pharmaceutical intervention effectiveness in the Marche region

Annals of Public and Cooperative Economics, Volume 97, Issue 2, Page 469-501, June 2026.
Abstract This study investigates whether prior exposure to natural disasters influenced individual compliance with non‐pharmaceutical interventions (NPIs), specifically lockdown measures, during the Corona Virus Infectious Disease 2019 (COVID‐19) pandemic. Focusing on the Marche region of Italy, which experienced a severe earthquake in 2016, we exploit

Validation of Physics‐Based Simulated Accelerograms for Seismic Fragility Analyses of Italian RC Existing Building Types

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This article aims at exploring and validating the use of 3D physics‐based simulated ground motions as seismic input for the derivation of seismic fragility curves based on nonlinear dynamic numerical analyses. Fragility curves are computed for a set of pre‐code (i.e., designed only for vertical loads), reinforced concrete building types representative ...

Bayesian analysisof a probability distribution for local intensity attenuation

Annals of Geophysics, 2004
Intensity attenuation and its variation as a function of the distance and earthquake size is still a critical issue in evaluating seismic hazard. We present a method that allows us to incorporate additional information from the historical earthquake felt

Near‐Source Ground Motion From Normal Faults: Insights From the Physics‐Based Numerical Simulations of the 1980 Irpinia Earthquake, Southern Italy

Earthquake Spectra, Volume 42, Issue 2, May 2026.
In this paper, the physics‐based numerical simulation of the strongest instrumental earthquake in the recent seismic history of Italy, i.e., the Nov 23, 1980 Irpinia earthquake in Southern Italy, with magnitude MW 6.8, is presented and discussed. A 3D spectral element model covering an extended region (147 × 110 km2) was constructed, with a frequency ...

SEISMIC HAZARD MAP FOR THE ITALIAN TERRITORY USING MACROSEISMIC DATA

Earth Sciences Research Journal, 2006
A seismic hazard map, in terms of macroseismic intensity, is proposed for the Italian continental territory and Sicily, which has a 10% probability of exceedance in 50 years.
