Question
8:42 PM anoes) Discussion 2 (Volcanoes) Chose a historically significant volcanic eruption and describe it. Your textbook includes some events of note, but there have been many more throughout the course of history. What happened before during and after the eruption? Was the eruption a surprise? Why or why not? What was the VEI? How did the geologic setting affect the VEI? What type of volcano was responsible? What causes the most damage or deaths (lahars, ash, landslides, pyroclastic flows) during and after the eruption? Why? What was the e you have done as a policy maker to save lives and or property before the eruption? ruption history of that area? What wouldExplanation / Answer
•For example, eruption of Vesuvius in 79 AD destroyed the city of Pompeii
On August 24, 79AD Mount Vesuvius literally blew its top, erupting tonnes of molten ash, pumice (volcanic rock that contains many vesicles/bubbles) and sulfuric gas miles into the atmosphere.
Pyroclastic flows reached the city of Pompeii and surrounding areas, devastating everything in it’s path…
Pyroclastic flows of poisonous gas and hot volcanic debris engulfed the cities of Pompeii, Herculaneum and Stabiae suffocating the inhabitants and burying the buildings.The cities remained buried and undiscovered for almost 1700 years until excavation began in 1748. These excavations continue today and provide insight into life during the Roman Empire.
The people and animals of Pompeii died in their sleep or trying to evacuate the town. If you visit Pompeii today you can see their remains…
Mt Vesuvius is still classed as an Active Volcano.the major Italian city of Naples lies approximately 30 km from the volcano vent. 1.5 million people live in Naples and as pyroclastic flows can travel as far as 100km from source, the city is built well within the danger zone!
•Vesuvius remains a hazardous volcano with heavily populated flanks:
–around 1.5 million people live in the city of Naples alone
–Naples is situated approx. 30 km from Vesuvius
–Pyroclastic flows can flow up to 100 km from the source!
yes, the eruption was a surprise event. this event has was of 5.
pyroclastic flow and ash causes a larger damage as their aerial extent is large .
today we can evacuate the city before such event has happened their are many early warning systems that can be used,
