The Eruption Of Vesuvius - Absolute History
As the descending landmass sinks deep into the Earth, temperatures and pressures climb, releasing water from the rocks. The water slightly reduces the melting point of the overlying rock, forming magma that can work its way to the surface—the spark of life to reawaken a slumbering volcano. Not all volcanoes are related to subduction, however. Another way volcanoes can form is what's known as hotspot volcanism. In this situation, a zone of magmatic activity —or a hotspot—in the middle of a tectonic plate can push up through the crust to form a volcano. Although the hotspot itself is thought to be largely stationary, the tectonic plates continue their slow march, building a line of volcanoes or islands on the surface.
This mechanism is thought to be behind the Hawaii volcanic chain. Some 75 percent of the world's active volcanoes are positioned around the ring of fire , a 25,mile long, horseshoe-shaped zone that stretches from the southern tip of South America across the West Coast of North America, through the Bering Sea to Japan, and on to New Zealand. This region is where the edges of the Pacific and Nazca plates butt up against an array of other tectonic plates.
Importantly, however, the volcanoes of the ring aren't geologically connected. In other words, a volcanic eruption in Indonesia is not related to one in Alaska, and it could not stir the infamous Yellowstone supervolcano. Volcanic eruptions pose many dangers aside from lava flows. It's important to heed local authorities' advice during active eruptions and evacuate regions when necessary. One particular danger is pyroclastic flows, avalanches of hot rocks, ash, and toxic gas that race down slopes at speeds as high as miles an hour. Such an event was responsible for wiping out the people of Pompeii and Herculaneum after Mount Vesuvius erupted in A. Similarly, volcanic mudflows called lahars can be very destructive.
These fast-flowing waves of mud and debris can race down a volcano's flanks, burying entire towns. Ash is another volcanic danger. Unlike the soft, fluffy bits of charred wood left after a campfire, volcanic ash is made of sharp fragments of rocks and volcanic glass each less than two millimeters across. The ash forms as the gasses within rising magma expand, shattering the cooling rocks as they burst from the volcano's mouth. It's not only dangerous to inhale , it's heavy and builds up quickly. Volcanic ash can collapse weak structures, cause power outages, and is a challenge to shovel away post-eruption. Volcanoes give some warning of pending eruption, making it vital for scientists to closely monitor any volcanoes near large population centers.
Warning signs include small earthquakes, swelling or bulging of the volcano's sides, and increased emission of gasses from its vents. None of those signs necessarily mean an eruption is imminent, but they can help scientists evaluate the state of the volcano when magma is building. However, it's impossible to say exactly when, or even if, any given volcano will erupt. Volcanoes don't run on a timetable like a train. The deadliest eruption in recorded history was the explosion of Mount Tabora in Indonesia. The blast was one of the most powerful ever documented and created a caldera —essentially a crater—4 miles across and more than 3, feet deep.
A superheated plume of hot ash and gas shot 28 miles into the sky, producing numerous pyroclastic flows when it collapsed. People ran for their lives with torches, screaming and some wept as rain of ash and pumice fell for several hours. While the eruption lasted for around 24 hours, the first pyroclastic surges began at midnight, causing the volcano's column to collapse. An avalanche of hot ash, rock and poisonous gas rushed down the side of the volcano at more than mph, burying victims and remnants of everyday life. Hundreds of refugees sheltering in the vaulted arcades at Herculaneum, clutching their jewelry and money, were killed instantly.
As people fled or hid in their homes, their bodies were covered by blankets of the surge. It's estimated some 2, people died in Pompeii and Herculaneum alone. This event ended life in the cities but preserved them until their rediscovery by archaeologists nearly years later. The excavation of Pompeii, the industrial hub of the region and Herculaneum, a small beach resort, has given unparalleled insight into Roman life. Archaeologists are continually uncovering more from the ash-covered city. In recent years, they uncovered an alleyway of grand houses, with balconies left mostly intact and still in their original hues. Some of the balconies even had amphorae - the conical-shaped terra cotta vases that were used to hold wine and oil in ancient Roman times.

Mount Etna continued its spectacular eruptions on Monday into Tuesday with jets of lava reaching a thousand meters ft into the air. The eruptions have awed even seasoned volcanologists in recent days with spurts of lava lighting up the Sicilian sky each night. Some said Monday's eruption - that continued into the early hours of Tuesday - was the most powerful during its recent burst of activity, with one expert saying an eruption of its kind had not been seen for decades at Etna. Pictured: A handout satellite photo dated 18 February and made available by the European Space Agency showing lava flowing down the side of Mount Etna, which has been erupting over the last week.
The latest eruption overnight by Europe's most active volcano petered out on Tuesday morning, according to Italy's National Institute for Geophysics and Volcanology. It comes as a satellite image was released showing what its deadly rivers of lava look like from space. For more than a week, Etna has been belching lava, ash and volcanic rocks on a regular basis. Nearby Catania Airport closed temporarily, and residents of the town of Pedara said it appeared one day last week as if it were raining rocks as a thick blanket of ash covered the town.
Slideshow continues on the next slide. Volcanologist Boris Behncke, of the national institute's Etna observation center, has followed the latest eruptions with awe. Writing on the institute's website, he said that after 'gifting us moments of suspense' over the previous nights, Etna finally erupted in a way 'those of us who have worked in this for decades have rarely seen'. The warning signs were there but the Romans in this region had become accustomed to such seismic activity. According to Pliny the Younger, the only eyewitness to leave behind a surviving written document of the events, such minor earth tremors were frequent in Campania. On this occasion, however, they represented something far more sinister; the sleeping giant was rousing.
The pressure exerted by the molten rock underneath the volcano was increasing to such a point it would soon have nowhere to go but up. At 1 pm on 24 August, Mount Vesuvius announced its awakening with a violent eruption. An enormous dark cloud shrouded the blue sky above the volcano. The column of volcanic pumice, hot gasses and ash, pushed upwards of 9 miles into the atmosphere and spread across the skyline like black ink on blotting paper. Every second one and half million tons of volcanic debris spewed into the atmosphere, regurgitated from the fiery depths of the raging giant.
It didn't take long for the dark cloud to travel the five-mile distance to Pompeii. The city soon found itself enveloped in darkness as molten rock, pumice stone and hot ash began to fall from the sky. Some people fled towards the sea, others into the nearby countryside. Many decided to huddle inside their homes in the vain hope of riding out the storm. The first deaths in Pompeii were recorded at this stage as the flat roofs of buildings and houses began to collapse under the weight of the ash and volcanic debris, crushing those unfortunate souls who dwelled within their walls. Rocks falling from the sky claimed the lives of others. Gradually the city became buried under ash and debris to a depth of almost 10m. Although located some 3 miles closer to Mount Vesuvius than Pompeii, the small wealthy seaside town of Herculaneum managed to dodge the majority of the ash and pumice fall from the first eruption, thanks to prevailing winds blowing the volcanic cloud southeast towards Pompeii and the surrounding area.
The apocalyptic scene unfolding in front of their eyes, however, was enough to convince the majority of the citizens of Herculaneum to flee from their city. They were the wise ones, as Mount Vesuvius was far from done yet. Around 1 am, twelve hours after the volcano had roared into life, the eruption moved into its second and most lethal phase. The column of debris and gas now reached some 20 miles high and began to weaken under its own weight.
In the early hours of August 25th, the column collapsed as the gasses densified and could no longer support their solid contents. The destructive cloud began to race down the sides of the volcano. This was the first of six pyroclastic surges that would fall from Mount Vesuvius that day. It raced towards the town of Herculaneum at speeds over mph. For years historians believed that Herculaneum was mostly abandoned by the time the surges came, due to the low number of skeletal remains discovered in the town.In recent years, they uncovered an alleyway of grand the destruction of pompeii and herculaneum, with balconies the destruction of pompeii and herculaneum Lincolns First Inaugural Address Summary intact and still in their original hues.
