From: Dyke intrusion and stress-induced collapse of volcano flanks: The example of the 2018 event at Mt. Etna (Sicily, Italy)

Figure 3

Vertical sections of VP and VP/VS along the traces reported in Fig. 1 and relocated seismicity across the volcano. Purple lines delimit the well resolved regions (SF ≤ 3.0). Red stars are ML ≥ 4.0 earthquakes and yellow star is the December 26 MW = 4.9 earthquake. The box indicates the extent of the intrusive dyke [from30]. Dashed red lines mark the compressional structure within the sedimentary cover, as retrieved from VP anomalies. The white line indicates the decollement layer, at the top of the sedimentary units.
