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 ...

Annals of Geophysics, 1996 In contrast to the case of instrumental data, the procedures for epicentral parameter determination (coordinates and I0) from macroseismic data are not very well established. Although there are some "rules", upon which most seismologists agree (centre of

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.

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

Tectonics, Volume 45, Issue 3, March 2026.Abstract Earthquakes in intraplate regions are often scattered and difficult to associate with specific geological structures, requiring detailed surveys to identify active faults. Improving knowledge of local seismicity in these areas is essential for accurate seismic hazard assessment and for safe planning of economic activities that could affect ...

Seismological Research LettersWe recompute the coefficients of the intensity prediction equation (IPE) in Italy using the data of the DBMI15 version 2.0 (v.2.0) intensity database and the instrumental and combined (instrumental plus macroseismic) magnitudes reported by the CPTI15 v.

Earthquake Spectra, Volume 42, Issue 1, February 2026.This paper introduces a procedure to estimate moment magnitude (MW) in earthquake‐induced soil liquefaction probabilistic risk assessment. The method is based on using the historical seismicity modelled with a truncated Gutenberg‐Richter (G‐R) relation, jointly with an empirical model linking the MW to the maximum source‐to‐site distance at which soil ...

National borders earthquakes: an attempt at intensity maps unification
Annals of Geophysics, 1994 In this paper the problem of unification of macroseismic maps across national borders is discussed. Up to now some attempts in this way have been carried out, evidencing the difficulties present in such analysis.
