labatt did him argue, marcus, the, some of the bowl. aetna is constantly creating new craters. book. a new ova is the youngest of the 4 craters on the summit. it appeared in 1968 to the west of the central crater cone. unlike the volcanoes of the bay of naples, aetna is situated at the crossroads of several tectonic plates. it's in contact not only with the eurasian and african plates, also with the micro plates of the geranium and ione, and sees these geological confrontations produce huge quantities of magma. which in turn generate intense activity. the mac, my is relatively fluid, and the gas bubbles move freely. therefore they rise to the surface quicker than the magnetic fluid. in contrast, the magma within vesuvius and the flip green fields, is much more viscous. this means it's harder for the gas bubbles to escape, causing a build up of pressure. this could generate explosive eruptions with huge destructive power. the prevailing theory to date has been that in the case of mount etna, small gas bubbles merged to make larger ones. these rise in the vents faster than the mach mat
