how many times has mount vesuvius erupted since 79 ad
Mount Vesuvius Vesuvius has erupted many times since and is the only volcano on the European mainland to have erupted within the last hundred years. Today, it is regarded as one of the most dangerous volcanoes in the world because of the population of 3,000,000 people living nearby, making it the most densely populated volcanic region in the world, as well as its tendency towards violent, explosive eruptions of the Plinian type.[5]
Mount Vesuvius Mount Vesuvius is best known for its eruption in AD 79 that led to the burying and destruction of the Roman cities of Pompeii and Herculaneum, as well as several other settlements. The eruption ejected a cloud of stones, ashes and volcanic gases to a height of 33 km (21 mi), spewing molten rock and pulverized pumice at the rate of 6×105 cubic metres (7.8×105 cu yd) per second,[2] ultimately releasing a hundred thousand times the thermal energy released by the Hiroshima-Nagasaki bombings.[3] More than 1,000 people died in the eruption, but exact numbers are unknown. The only surviving eyewitness account of the event consists of two letters by Pliny the Younger to the historian Tacitus.[4]
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]
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]
Eruption of Mount Vesuvius in 79 Mount Vesuvius, a volcano in modern-day Italy, erupted in 79 in one of the most catastrophic volcanic eruptions in European history. Historians have learned about the eruption from the eyewitness account of Pliny the Younger, a Roman administrator and poet.[1] The event is the namesake for the Vesuvian type of volcanic eruption.
Mount Rainier The most recent recorded volcanic eruption was between 1820 and 1854, but many eyewitnesses reported eruptive activity in 1858, 1870, 1879, 1882 and 1894 as well.[38]
