What is the elevation of Mount Vesuvius?
summit elevation 1281 m, Complex volcano. Mount Vesuvius is one of the world’s most dangerous volcanoes. The volcano has an eruption cycle of about 20 years, but the last eruption was in 1944. The volcano is rated as one of the most dangerous in the world with millions of people living close to the crater.How big was the earthquake that hit Mount Vesuvius in 1999?
At 7:41 am local time on 9th October 1999 a magnitude 3.6 earthquake hit Mt Vesuvius, as part of the largest earthquake swarm since 1944. The earthquake was felt in a 25 km radius of the volcano. This earthquake was the same size as the precursor of the great 1631 eruption.What type of volcano is Somma-Vesuvius?
Information is preliminary and subject to change. All times are local (unless otherwise noted) The Somma-Vesuvius volcanic complex is a central composite volcano formed by an older stratovolcano (Monte Somma) with a summit caldera partially filled by the composite cone of Vesuvius.
What happened in the year 1906 at Mount Vesuvius?
1906 Eruption. An eruption began at Mt Vesuvius on 4th April 1906 when an effusive vent opened on the southern slope at an altitude of 1200 m, near Casotto delle Guide. At midnight on 4th April the lava flow ceased when a new fracture opened up near the cistern of Casa Fiorenza at an elevation of about 800 m elevation.
How old is Mount Somma-Vesuvius?
Somma-Vesuvius is a composite volcanic complex composed of an older stratovolcano (Mt. Somma) and a younger crater (Mt. Vesuvius). The earliest outcropping volcanic deposits date back to about 25,000 years ago. The lavas observed at a -1125 m bore-hole are about 0,3-0,5 million years old.How long did it take for Vesuvius 79 AD to erupt?
The figure given for the Plinian phase of Vesuvius 79 AD eruption is eighteen hours. The depth of the pumice and pyroclastic flow deposits, 20 metres at Herculaneum and 2.8 m pumice plus several metres of pyroclastics at Pompeii, 11 km from the volcano, are comparable.Was the 79 AD eruption of Vesuvius a VEI 5 eruption?
It was also where Spartacus had his lair during the Third Servile War (73–71 BC) From this evidence it is clear that the 79 AD eruption was, not a VEI 5, but a VEI 6 eruption that resulted in a collapse of Vesuvius where the volcano lost over a km in height and created the caldera whose highest point was afterwards named Monte Somma.
What type of magma was in Mount Vesuvius in 1944?
A shallow and deep magma reservoir was involved in the 1944 eruption of Mt Vesuvius volcano; depths of less than 3 km deep and 11-22 km. The shallow reservoir feeding the 1944 eruption was completely emptied and collapsed during the final phases of the eruption.
