“…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. To the north of this alignment, the alkaline volcanics cover the buried clastic deposits with a contact resting almost at the sea level (Ferrara, 1976; La Delfa et al., 2011). On the Acitrezza Ridge, the base of the volcanics, directly resting on the marly clay substratum without the interposition of the clastic horizons, crops out at a minimum elevation of about 120 m a.s.l.…”

“…The profile in Figure 2 images the location of the buried Fiandaca normal fault, immediately to the southeast of its active portion. The NE‐SW geological transect combines field data, used to reconstruct the geometry of the up‐thrown block, with the interpreted electro‐stratigraphy (Cassinis et al., 1970; La Delfa et al., 2011), which highlights the layering in the subsided block. The interpolation of the location of the fault both drawn along the geological transect of Figure 2 and inferred by seismic line offshore the Acitrezza‐Acireale area, depicts an overall NNW‐trending trace, joining the reactivated portion of the Fiandaca normal fault.…”

A detailed study had been conducted on the sediment of Mount Samalas' volcanic eruption in 1257 AD. Using the framework of the reconstruction of the ancient eruption of Mount Samalas, the first step was to map and analyze the deposits of volcanic sediment. Secondly, we analyzed the effect of geomorphology and the distance function to the isopach thickness. The results show that a combination of methods allowed to provide a high resolution map of the distribution of the thickness of the volcanic deposits, both on the slope and in alluvial areas. Geo-electric survey results (both Vertical Electric Sound (VES) and 2D mapping) show consistent changes in the pattern of contrast resistivity layer interface, for all areas. The pattern changes in a row of the top layer, the high resistivity turned into the low. Furthermore, the second and third layer interface changes from low to the high resistivity. High resistivity on the top layer is interpreted as a layer of unconsolidated volcanic sediment. High resistivity values are range from 736 to 2000 Ohm.m on the top layer in the area of the slopes while in the area of alluvial, the resistivity values range from 20 to 958 Ohm.m. Generally, the volcanic deposits in the area of the slopes have a higher value of isopach (>17 m) than in areas of alluvial (<25 m). The geomorphology seemed to have no significant effect on the isopach value, particularly pyroclastic fallout. Such is the case with distance from the source to the site, which is not linear. The value of isopach increases westward from 21 to 31 km, in contrast to the East, which began to occur at a distance of 14 km to 21 km.
