Fig. 1: Mt. Etna Seismicity and tectonic lineaments.
From: Re-pressurized magma at Mt. Etna, Italy, may feed eruptions for years
(a) Map of Mt Etna volcano and main faults and tectonic lineaments (white lines). Seismicity in the period January 2019–February 2021 is shown, with crosses color-coded for hypocentral depth (red = z ≤ 3 km, blue = 3 < z ≤ 12 km, black = z ≥ 12 km, b.s.l.). (b) 3D view of the seismicity distribution, note the central shallow and the peripheral deep seismicity.
