Volcano Eruptions BY: Megan Ruff
Colleen Waldron What Damage Do
Volcanoes Cause More interesting facts!!! How Can We Survive It? Interesting facts on volcanoes!!! YOUTUBE!!!!!! Volcanoes are known to cause Tsunami formation which leads to crop failure, lost housing, pollution (mainly acid rain), disrupted traffic, destroyed buildings, earthquakes, and lava. Learn your community's morning system.
Be prepared for the impact. This includes earthquakes, flash floods, landslides, mud flows, and thunderstorms.
Plan an evactuation route to high land but have a back up plan ready just in case.
Purchase goggles and a disposable breathing mask. a volcano is a mountain that opens downward to a pool of molten rock (magma) below the surface of the earth. It is a hole in the Earth from which molten rock and gas erupt.
Magma is liquid rock inside a volcano
Lava is liquid rock (magma) that flows out of a volcano. Fresh lava ranges from 1,300° to 2,200° F (700° to 1,200° C) in temperature and glows red hot to white hot as it flows.
There are around 1510 'active' volcanoes in the world. We currently know of 80 or more which are under the oceans.
The biggest volcano on Earth is Hawaii’s Mauna Loa. One of the five volcanoes in Hawaii, it towers 13,000 feet above sea level. The Hawaiian Islands were actually created by a hot spot. The crust is the outer layer of Earth. It is about 18 miles thick. It is the part we live on.
The second layer is called the mantle. It is about 1,800 miles thick.
The inner layer is called the core. Stock up on supplies such as flashlights and batteries, a battery operated radio, first aid kit, and tons of canned food and water.
Avoid downwind areas and areas of a volcano, they are the most dangerous.
When going outside, wear long pants and a long shirt.
If you are in a car during the eruption, leave the engine off. How Do We Recover From It? Usually, after an eruption, the area would be destroyed. If you were to start over, it would be after quite a few years. However, if it was an eruption of ash and cinder, the best way would be to sweep away the volcanic remains. Also, help would most likely be sent to aid the area. What Is It? Volcano- a vent in the Earth's crust through which lava, steam, ashes, etc. are expelled either continuously or at irregular intervals. Lessen damage on the society
