Mt. Vesuvius??????

Question

What is the eruption style of Mt. Vesuvius? What is its magma composition? Is it dormant, extinct, or active?

U ONLY HAVE TO ANSWER ONE OF THEM IF U WANT...ALL OF THEM WOULD BE GREAT!!!!=)

Answer 1

The eruption style is Plinian, named after Pliny the younger, who watched the AD 79 eruption and wrote a description.  It is also sometimes called a Vesuvian type eruption.

Vesuvius is active.

Magma composition called tephra

The rocks at Vesuvius are called tephrite. A tephrite is basaltic in character and contains the following minerals: calcic plagioclase, augite, and nepheline or leucite.

Vesuvius is a dangerous and deadly volcano. Mudflows and lava flows from the eruption in 1631 killed 3,500 people. About 3,360 people died in the 79 A.D. eruption from ash flows and falls. Studies of past eruptions and their deposits continue. These studies help volcanologists understand the hazards associated with future eruptions. The population density in some areas of high risk is 20,000 to 30,000 per square km. About 3 million people could be seriously affected by future eruptions. In the first 15 minutes of a medium- to large-scale eruption an area with a 4 mile (7 km) radius of the volcano could be destroyed (Dobran and others, 1994). About 1 million people live and work in this area.

There are no signs of volcanic unrest at Vesuvius at the present time (February 1996).

Vesuvius is above a subduction zone. The African plate is moving northward at about one inch (2-3 cm) per year and is slowly closing the Mediterranean basin. As it moves to the north, the African plate is pushed beneath the Eurasian plate.

Answer 2

Mt. Vesuvius didn't blow much magma, mostly toxic gas and ashes, which is what killed everyone. I think it's extinct, but I wouldn't bet on it. Well, I would, but not much.
