Eugenio Privitera, director of Catania National Institute of Geophysics and Volcanology (INGV) said: "We are starting a new
eruptive phase of Etna which could end soon or last months.
It was only a decade ago, China hosted the Olympic Games; Cyprus and Malta adopted the euro; May was a bad month because a Chilean volcano entered an '
eruptive phase' for the first time since 1640; cyclone Nargis devastated Myanmar accounting for 138,000 deaths; a 7.9 magnitude earthquake in Sichuan left 87,000 dead.
least for this
eruptive phase. This suggestion was born out in October
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.
Patients may have a prodrome of fever, arthralgias, and often symptoms of an upper respiratory infection occurring 2 to 8 weeks before the
eruptive phase. (1,2)
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.
During the Cretaceous period they proliferated, then disappeared.) 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.
