Provides homogeneous set of macroseismic intensity data collected from several sources, for Italian earthquakes with maximum ≥ 5 in the period 1000-2014.
The 2002–2003 Etna eruption is studied through earthquake distributions and surface fracturing. In September 2002, earthquake‐induced rupture (sinistral offset ∼0.48 m) occurred along the E‐W striking Pernicana Fault (PF), on NE flank. late October, a flank accompanied further (∼0.77 rupturing, reaching total sinistral of 1.25 m; deformation then propagated for 18 km eastwards to coastline 0.03 southwards, NW‐SE Timpe (dextral 0.04 and, later, Trecastagni faults 0.035 m). Seismicity (<4...
In this paper we report seismological evidence regarding the emplacement of dike that fed July 18 - August 9, 2001 lateral eruption at Mt. Etna volcano. The shallow intrusion and opening eruptive fracture system, which mostly occurred during 12, 18, were accompanied by one most intense seismic swarms last 20 years. A total 2694 earthquakes (1 £ Md 3.9) recorded from beginning swarm (July 12) to end (August 9). Seismicity shows upward migration basement relatively thin volcanic pile. clear...
<p>The 24 August 2016 earthquake very heavily struck the central sector of Apennines among Lazio,Umbria, Marche and Abruzzi regions, devastating town Amatrice, nearby villages other localities along Tronto valley. In this paper we present results macroseismic field survey carried out using European Macroseismic Scale (EMS) to take heterogeneity building stock into account. We focused on epicentral area, where geological conditions may also have contributed severity damage. On whole,...
In recent years, new approaches for developing earthquake rupture forecasts (ERFs) have been proposed to be used as an input probabilistic seismic hazard assessment (PSHA). Zone- based with seismicity rates derived from catalogs are commonly in many countries the standard national models. Italy, a single zone- ERF is currently basis official model. this contribution, we present eleven ERFs, including five zone-based, two smoothed seismicity-based, fault- based, and geodetic-based, PSH model...
<p>Instrumental seismic catalogues are an essential tool for the zonation of territory and production hazard maps. They also a valuable instrument detailed seismological studies regarding active volcanoes and, above all, interpreting magma dynamics evolution eruptive phenomena. In this paper, we show first instrumental earthquake catalogue Mt. Etna, period 2000-2010, with purpose producing homogeneous dataset 10 years observations. During period, 16,845 earthquakes have been recorded...
We present a 1:10,000 scale map of the coseismic surface ruptures following 26 December 2018 Mw 4.9 earthquake that struck eastern flank Mt. Etna volcano (southern Italy). Detailed rupture mapping is based on extensive field surveys in epicentral region. Despite small size event, we were able to document faulting for about 8 km along trace NNW-trending active Fiandaca Fault, belonging Timpe tectonic system volcano. The mapped are characterized most cases by perceivable opening and dominant...
A detailed analysis of the intensity attenuation in Etna and other Italian volcanic districts, was performed using most recent complete datasets. Attenuation laws were derived through empirical models fitting ?I (the difference between epicentral I0 site Ix intensities) average values versus hypocentral distances by least-square method. The huge amount data available for area allowed us to elaborate bi-linear logarithmic models, also taking source effects into account. Furthermore,...

In this study, seismic hazard, a component of the multi‑hazard assessment studied in framework PANACEA project, was performed following probabilistic approach (PSHA) based on historical macroseismic data. This uses intensity site observations to compute history for each investigated locality. Site histories completeness are improved integrating observed intensities with “virtual” values calculated according attenuation laws, starting from earthquake parameters (epicentre and epicentral...
We provide a database of the surface ruptures produced by 26 December 2018 Mw 4.9 earthquake that struck eastern flank Mt. Etna volcano in Sicily (southern Italy). Despite its relatively small magnitude, this shallow caused about 8 km faulting, along trace NNW-trending active Fiandaca Fault. Detailed field surveys have been performed epicentral area to map and characterize their kinematics. The show dominant right-oblique sense displacement with an average slip 0.09 m maximum value 0.35 m....
Abstract. The volcanic region of Mt. Etna (Sicily, Italy) represents a perfect lab for testing innovative approaches to seismic hazard assessment. This is largely due the long record historical and recent observations tectonic phenomena, high quality various geophysical monitoring particularly rapid geodynamics clearly demonstrate some seismotectonic processes. We present here model components procedures adopted defining sources be used in new generation probabilistic assessment (PSHA),...
Abstract In this paper, we tackle the problem of intensity attenuation at Ischia, a critical parameter in high seismic risk area such as volcanic island. Starting from new revised catalogue local earthquakes, select dataset 118 macroseismic observations related to four main historical events and analyse characteristics according both deterministic probabilistic approaches, under assumption point source isotropic decay (circular spreading). analysis, derive law through an empirical model...
Abstract. This paper describes the model implementation and presents results of a probabilistic seismic hazard assessment (PSHA) for Mt. Etna volcanic region in Sicily, Italy, considering local volcano-tectonic earthquakes. Working new challenges not typically faced standard PSHA, which are broadly due to nature earthquakes, cone shape volcano attenuation properties waves region. These have been accounted through development source that integrates data from different disciplines (historical...
