Transcript of Volcanoes

On September 14th, 2012 an active volcano in Antigua erupted, drawing fascinated tourists. Villagers call this volcano Volcan del Fuego, The volcano of fire. Volcan del Fuego is located at 14.47°N / -90.88°W in the Sierra Madre mountain range and is 12,346 ft. tall. It has erupted 57 times since 1581. The volcano spewed 3000 ft streams of lava and Guatemalan authorities have put it on the highest alert level. The following slides will depict how volcanoes erupt and the damage they can cause. Volcano in Guatemala! Volcanoes form when pressure and stress in the Earth's crust cause an upward motion of magma. This causes the eruption. The more pressure that is built up inside the volcano, the greater the eruption. The pressure can be caused by a large mass of rock in one area. The Volcan del Fuego was formed by the collapse of the Meseta volcano, about 8,500 years ago. Below, is a video of Mexico's rumbling volcano, Popocatepetl, which spews smoke due to its large amount of pressure. The Mexican military has been watching the volcano for signs on an eruption. The magma travels upward vertically through the magma chamber, a large underground pool of molten rock, beneath the Earth's surface, that leads to the opening of the volcano Occasionally, the magma chamber will break, causing magma to spill from the sides of the volcano. This happens when the volcano is not active enough to push the magma to the surface or the volcano. If these unactive volcanoes do erupt, then they release smoke, ash, and gas bubbles that mix with minerals to form volcanic rock. The Volcan del Fuego emitted clouds of ash that were 800m high. VOLCANO!!! If the magma chamber remains unbroken, and the magma reaches the surface of the volcano, the volcano erupts. Stratovolcanoes, like the Volcan del Fuego, are larger and can contain more magma.The magma explodes from the volcano, shooting lava, rocks, ash, smoke, and flame into the air. The volcano's contents the spill down the summit and to it's base. Volcanoes can cause damage to buildings, destroy landscapes, and kill whole cities of people. The ash and smoke can get into the air and suffocate wildlife. Disaster relief organizations have been formed to give aid to those whose lives have been affected by volcanoes We learned that an average of 869 people are killed by volcanoes a year What Did We Learn? We found it interesting that volcanoes can also form underwater What did we find Interesting? How long was the Guatemalan volcano at the highest level?
How many volcanoes are located in Guatemala?
How many people were injured or killed in the Volcan del Fuego eruption? Questions? By: Peter Caroline & Kaine Mardilan Vocabulary magma- molten rock inside the Earth
lava- molten rock on Earth's surface
summit- the face of a mountain or volcano
magma chamber- an underground pool of magma leading to the opening of the volcano
Stratovolcano- a volcano that is unusually large and powerful
