Sunday night ended the latest spectacular eruptive phase
of the Sicilian volcano, Mount Etna.
Clay from that dig had been carbon-dated, placing it around 7,500 to 7,600 years old, which matches up with the latter half of the 200-year eruptive phase
of Mazama, probably after the mountain's collapse.
While volcanologists stress that they can't predict what will happen from one day to the next, the current eruptive phase
has shown no sign of diminishing.
Four (4) eruptive phases
were distinguished in the medial zone where it reaches 10 m thick (Figures 11 c): two sets of planar and sand wave facies typical of surge deposits, fine-grained and cross-laminated beds with sand wave facies containing accretional lapilli.
The irregular patterns of subsidence and the discovery of late-stage eruptive phases
in some guyots make our theoretical models for thermal rejuvenation and seamount subsidence less predictable.
