Volcano Eruption Documentary Bbc
Mount Vesuvius has had eight dangerous eruptions in the past 17,000 years. The most famous on one Pompeii was in 79 AD, killing more than 16,000 people and perceiving their skeletons. The last eruption was March 18th to the 23rd of 1944, destroying many villages in its path. During the eruption there was a cloud of stones, ash, and volcanic gases; 21 miles high. It released 100,000 times the thermal energy than the Hiroshima bombing. It is still considered an active volcano, and very likely to explode again. With the population of 3 million living around this volcano, this is one of the most dangerous. There is an emergency plan in place for eruption detection, ideally giving the people about 20 days to escape by ferry, car, and bus; there would but about 600,000 people needing to evacuate. They expect this to take seven days, so without this notice the event would be very deadly.
This volcano is a somma-stratovolcano. The volcanos caldera started forming 17,000 years ago during an eruption, then expanded at a later date during another explosion. This volcano has a multi-phase eruption. The main explosion of ash and pumice that can range to about 49-91 thousand feet high. Then the gases expand and can no longer hold the mixture, and releases it. This is what buried the famous event at Pompeii.
It is located in the Metropolitan City of Naples, Italy. It is 1,000 feet deep and 2,000 feet long.
