Transcript of Mt. Etna
Listen to the officials, and do what they instruct you to do. Also stay out of the blocked areas called risk zones. Even certified scientist can't go to the risk zones without giving a reason to the Sicilain government.
Mount Etna During Recent Eruption
Mt. Etna and the city of Catania in Sicily, Italy
Right underneath the Earth's crust is a layer called the mantle, which has plates that are always moving and shifting. Sometimes the plates separate. When that happens it creates heat and causes the mantle to melt into magma. Then magma comes up through the crack between the plates. The magma spreads, then cools into rock. Therfore, forming a volcano. Also, sometimes the plates collide. Then one plate can slide under the other. The magma pushes upward, and if the pressure is high enough or a crack opens in the crust, the magma spews out. Also, the gasses that are trapped inside the volcano have so much pressure that the volcano practically explodes.
The biggest eruption of Mount Etna, the more than 1/2 a million years old volcano, occurred on March 8, 1669. Mt. Etna is located in Sicily Italy. It is a composite volcano. Which means it could be explosive or non-explosive, in this case, Etna had a moderate eruption force. It was high in silica and low in H2O.
The death toll was approximately 20,000 people. So that obviously affected the life on Sicily, life before the disaster was about every day you were either farming on the slopes of the mountain or in the town of Catania. The effect on the environment was the crops were all gone by the time the eruption was over (the sides of the volcano had nice fertile dirt perfect for farming). The crops cost and took a long time to re-plant. The city of Catania was able to rebuild, however, 27,000 people became homeless.
The volcano covers more then 460 square miles. Around one quarter of the population on Sicily lives on its slopes.
Some of the lava on the side of Mount Etna is 300,000 years old. The geological and atmospheric conditions are very similar to those on Mars, that's why scientists test space robots here.

The warning signs of the big eruption were the volcano started rumbling and belching gas from its top. Also it started spewing noxious fumes.

This disaster could most definitely happen again because Mount Etna is a completely active volcano. The only way humans could prepare for it is by listening to officials and take extreme precautions while around this area.
An article from the Britannica encylopedia stated, "The name comes from the Greek Aitne, from aithō, “I burn.” Mount Etna is the highest active volcano in Europe, its topmost elevation being about 10,900 feet (3,320 metres)."
Mount Etna is one of the most intriguing volcanoes in history. I can predict that this continuously active volcano will keep producing lava and of course somewhat exploding for thousands of years to come.
