“…The NNW-trending Fiandaca normal fault is also clearly visible in the geodetic deformation field based on combined GPS and DInSAR data series (Bonforte et al, 2011(Bonforte et al, , 2013. The structure is part of a permanent scatterer feature (PSFs in the inset of Figure 1) that includes the roughly N-S-oriented active Nizzeti fault (nzf in the inset of Figure 1) (Branca et al, 2011;Servizio Geologico d'Italia, 2009). The 2018 event caused simultaneous ground fracturing along the entire arc-shaped tectonic belt (EMER-GEO Working group (Etna 2018 andCivico et al, 2019), although the macroseismic epicenter of the earthquake is located on the NW-trending dextral fault (Azzaro & D'Amico, 2019).…”

“…Where the shear zone intersects the border of the medieval lava flow (1329 A.D.; Branca et al, 2011), conjugate sets of coseismic N-S-oriented structures form a saw-toothed boundary of a discrete clockwise rotated wedge of the rigid lava body (Figure 9c). These N-S-oriented structures show prevalent left-lateral motion coupled with N40°-oriented contractional features, and are apparently incongruent with the overall right-lateral kinematics.…”

“…As the surface expression of the inferred active fault segments is extremely subdued, the structure was not reported in earlier geological maps of the region (e.g., Romano et al, 1979). More recent geological and morphological maps (e.g., Branca et al, 2011;Monaco et al, 2008;Servizio Geologico d'Italia, 2009) report only the NNW-trending normal fault of the active arc-shaped belt, hereinafter referred to as the Fiandaca normal fault (ff in the inset of Figure 1). In contrast,the trace of the dextral NW-oriented fault still remains undetermined.…”

“…The sedimentary substratum underlies a 300 m thick, low to medium resistivity horizon, consisting of buried clastic deposits. The top of this layer consists of high-resistivity alkaline lavas and lahar deposits, cropping out along the 180 m high sea-cliff of the Timpa di Acireale (Figure 2; Acireale Synthem of Branca et al, 2011;155-130 ky B.P.). This volcanic sequence dips gently toward the west-northwest (Panzera et al, 2020), and abruptly terminates against the raised marly-clay substratum.…”

“…The contact of the ancient lavas against the sedimentary substratum of the Acitrezza Ridge is buried beneath a veneer of lavas, associated with activity of the modern stratovolcano (<15 ky B.P. ; Branca et al, 2011). However, the huge vertical displacements of the base of the volcanics and the sharp change in the lithostratigraphy, are clear geological evidences of the effects of a tectonic discontinuity at the northern border of the Acitrezza Ridge.…”

Starting off from a review of previous literature on kinematic models of the unstable eastern flank of Mt. Etna, we propose a new model. The model is based on our analysis of a large quantity of multidisciplinary data deriving from an extensive and diverse network of INGV monitoring devices deployed along the slopes of the volcano. Our analysis had a twofold objective: first, investigating the origin of the recently observed slow-slip events on the eastern flank of Mt. Etna; and second, defining a general kinematic model for the instability of this area of the volcano. To this end, we investigated the 2008-2013 period using data collected from different geochemical, geodetic, and seismic networks, integrated with the tectonic and geologic features of the volcano and including the volcanic activity during the observation period. The complex correlations between the large quantities of multidisciplinary data have given us the opportunity to infer, as outlined in this work, that the fluids of volcanic origin and their interrelationship with aquifers, tectonic and morphological features play a dominant role in the large scale instability of the eastern flank of Mt. Etna. Furthermore, we suggest that changes in the strain distribution due to volcanic inflation/deflation cycles are closely connected to changes in shallow depth fluid circulation. Finally, we propose a general framework for both the short and long term modeling of the large flank displacements observed.

The geology of the 2nd century A.D. Amphitheater Area of Catania, Italy: Historical Eruptions Affecting the Urban District

et al. 2015

The amphitheater of Catania is one of the main architectural structures built during Roman domination of the town. It was constructed in two successive phases between the 1st and 2nd centuries A.D. and fell into disuse from the second half of the 4th century. Detailed geological and petrographic investigations allow better geomorphological reconstruction of the area where the monument was built. In particular, the western and eastern portions of the amphitheater are built on prehistoric lava flows, named Barriera del Bosco and Larmisi, respectively. We infer that the choice of site to build the monument was highly influenced by the morphological setting of the area. In fact, the location at the contact between two lava flow fields facilitated excavation and removal of rocks due to the incoherence of the scoriaceous lateral border of the lava flows. Integrating both archaeological and geological data has revealed that a large number of Neolithic, Greek, and Roman sites are located in the lava fields of Barriera del Bosco and Larmisi within the present urban district of Catania, indicating that during its long history the city was directly impacted by only one lava flow, namely in A.D. 1669.
