Short summary
Short summary
Earthquake surface ruptures are a hazard for infrastructure and life that requires proper assessment. We use a physics-based earthquake cycle simulator to derive fault displacement hazard statistics in a test fault system and their dependence to fault geometry. Our results show that more complex fault geometries increase surface rupture probabilities and might improve the agreement with observations. Earthquake cycle simulators are thus a promising tool for fault displacement hazard analyses.

We propose a scoring strategy to rank multiple models/branches of a probabilistic seismic hazard analysis (PSHA) model that could be useful to consider specific requests from stakeholders responsible for seismic risk reduction actions. In fact, applications of PSHA often require sampling a few hazard curves from the model. The procedure is introduced through an application aimed to score and rank the branches of a recent Italian PSHA model according to their fit with macroseismic intensity data.

Knowing the rate at which earthquakes happen along active faults is crucial to characterize the hazard that they pose. We present an approach (Paleoseismic EArthquake CHronologies, PEACH) to correlate and compute seismic histories using paleoseismic data, a type of data that characterizes past seismic activity from the geological record. Our approach reduces the uncertainties of the seismic histories and overall can improve the knowledge on fault rupture behavior for the seismic hazard.

We used 100 years of seismicity in Italy to predict the hypothetical tectonic style of future earthquakes, with the purpose of using this information in a new seismic hazard model. To squeeze all possible information out of the available data, we created a chain of criteria to be applied in the input and output selection processes. The result is a list of cases from very clear ones, e.g., extensional tectonics in the central Apennines, to completely random tectonics for future seismic events.

This study describes two hands-on outreach events: an interactive lesson for high-school students during European Researchers’ Night and a tsunami experiment at Lucca Comics & Games. Surveys showed both groups enjoyed the activities, boosted their grasp of geoscience ideas and grew more positive about science. The work emphasizes the effectiveness of quantitative experiment demonstrations and the need to adapt them to the audience, time available and clear educator coordination.

ASMI, the Italian Archive of Historical Earthquake Data, is an online data collection that currently provides seismological data on earthquakes that occurred in and around Italy from from 461 BCE to 2025 CE. Based on more than 450 data sources, ASMI's web portal distributes earthquake parameters and macroseismic intensity data, along with the bibliographical reference of the data source and – if possible – the data source itself, through queries by both earthquake and data source.

The 2020 European Seismic Hazard Model (ESHM20) is the latest seismic hazard assessment update for the Euro-Mediterranean region. This state-of-the-art model delivers a broad range of hazard results, including hazard curves, maps, and uniform hazard spectra. ESHM20 provides two hazard maps as informative references in the next update of the European Seismic Design Code (CEN EC8), and it also provides a key input to the first earthquake risk model for Europe.

We analyse and interpret seismic anisotropy from CIFALPS2 data that fill the gaps in the Western Alps and support a new hypothesis. Instead of a continuous mantle flow parallel to the belt, here we find a N–S mantle deformation pattern that merges first with a mantle deformed by slab steepening beneath the Central Alps and then merges with an asthenospheric flow sourced beneath the Massif Central. This new sketch supports the extinction of slab retreat beneath the Western Alps.

The earthquake effects undocumented at 228 Italian localities were calculated through a probabilistic approach starting from the values obtained through the use of an intensity prediction equation, taking into account the intensity data documented at close localities for a given earthquake. The results showed some geographical dependencies and correlations with the intensity levels investigated.

EPICA is the 1000–1899 catalogue compiled for the European Seismic Hazard Model 2020 and contains 5703 earthquakes with Mw ≥ 4.0. It relies on the data of the European Archive of Historical Earthquake Data (AHEAD), both macroseismic intensities from historical seismological studies and parameters from regional catalogues. For each earthquake, the most representative datasets were selected and processed in order to derive harmonised parameters, both from intensity data and parametric catalogues.

We present a probabilistic approach for integrating incomplete intensity distributions by means of the Bayesian combination of estimates provided by intensity prediction equations (IPEs) and data documented at nearby localities, accounting for the relevant uncertainties. The performance of the proposed methodology is tested at 28 Italian localities with long and rich seismic histories and for the strong 1980 and 2009 earthquakes in Italy. An application of this approach is also illustrated.

Short summary
As new data are collected, seismic hazard models can be updated and improved. In the framework of a project aimed to update the Italian seismic hazard model, we proposed a model based on the definition and parametrization of area sources. Using geological data, seismicity and other geophysical constraints, we delineated three-dimensional boundaries and activity rates of a seismotectonic zoning and explored the epistemic uncertainty by means of a logic-tree approach.
As new data are collected, seismic hazard models can be updated and improved. In the framework...
