Supervolcano located in the caldera of Phlegraean fields near the Italian city Naples, began to file clear signs of activity. Seismologists say that the surface temperature of the volcano has increased, which means that the approach of the magma to the surface.
In addition, a significant deformation of the surface soil was at Phlegraean fields. At some point near the city Potstsuolli lift soil in the past 12 months was 8 cm, the peak rise occurred in July-August 2012, the process is still ongoing. Although these upgrades can not be considered a rare event in the history of Phlegraean Fields, now a number of factors indicate that it is not just variations vnutrizemnogo pressure or density of rock.
In favor of the impending eruption said increasing the number of micro-earthquakes and increased the ratio of gases in a magmatic origin of the crater fumaroles solfataras. This could not be better expressed that the process of magma ascent to the surface running. Nevertheless, the nature and extent of future eruption, if it does happen, seismologists nothing concrete has been claimed, but prefer to strengthen the monitoring of Phlegraean fields.
Last eruption was observed in the area in 1538 after a 3-thousand-year sleep. Then in the caldera formed a new cone. As now, the eruption was preceded by lifting the surface of the caldera and bloating.
