what is the risk level of mt. vesuvius today
Mount Vesuvius The volcano is closely monitored by the Osservatorio Vesuvio in Naples with extensive networks of seismic and gravimetric stations, a combination of a GPS-based geodetic array and satellite-based synthetic aperture radar to measure ground movement and by local surveys and chemical analyses of gases emitted from fumaroles. All of this is intended to track magma rising underneath the volcano. No magma has been detected within 10Â km of the surface, and so the volcano is classified by the Observatory as at a Basic or Green Level.[66]

Backshore Sediments in this area are well-sorted and well-rounded. Its grain sizes are mainly coarse sand and medium sand, which are larger than that in littoral barrier dune.The sedimentary structures include parallel bedding and low-angle cross-bedding.
Eruption of Mount Vesuvius in 79 Mount Vesuvius spewed forth a deadly cloud of tephra and gases to a height of 33 kilometres (21Â mi), ejecting molten rock, pulverized pumice and hot ash at the rate of 1.5 million tons per second, ultimately releasing 100,000 times the thermal energy of the Hiroshima-Nagasaki bombings.[2] Several Roman settlements were obliterated and buried underneath massive pyroclastic surges and ashfall deposits, the best known being Pompeii and Herculaneum.[1][2]
