50to60 Volcanic Eruption

Volcanos are deadly, can form on islands or mainland, and can destroy mountains and cities. Volcanos commonly form from holes in the earth containing magma. When pressure builds up in these magma chambers, they explode resulting in magma and rock catapulting out into the air. As these volcanoes repeatedly explode, they leak magma, which runs down the side of the volcano. Eventually, the lava cools and transforms into solid rock, building up the volcano to mountain size. An example of giant volcanic eruptions is the Pompeii disaster in 79AD, when Mount Vesuvius erupted and destroyed all of Pompeii. Another example includes, the 1980 eruption of Mount St. Helens in Washington state, which destroyed the whole mountain. Volcanos

Stratovolcano and Shield volcanos are naturally occurring ruptures in the earth’s crust. They have been a part of our history for nearly 6,000 years and some say that they have been around longer than dinosaurs. While these events are rather cool to watch, they are known to be some of the most devastating natural disasters known to man. Volcanic hazards and eruptions continue to happen throughout the entire world and crisis aversion is something that is becoming more and more important.

A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also

Have you ever been near a volcano when it erupted? Most of us haven't, but if you're unlucky enough, you just might have. Many people think it would be cool, but it is indeed not. In fact, the people of Pompeii were very unlucky when Mount Vesuvius erupted in 79 AD. Nearly two-thousand people died. Although that eruption was very similar to the 1980 eruption of Saint Helens, it was also very different.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

11. The Kilauea Volcano eruption was one of the largest and the most destructive for its time, “As the lava field spread, cooled and spread again over the next three years it destroyed many homes and the Visitor Center…” (http://www.livescience.com/27622-kilauea.html) Familys and companys had no were to go, jusst like the the people in the Dust Bowl at the

● This was the first time this type of volcano eruption was actually witnessed and

Another well-known geological phenomenon in the United States is Yellowstone Park. Yellowstone is an extraordinary example of a caldera which is defined as “a volcanic crater that has a diameter many times that of the vent and is formed by collapse of the central part of a volcano or by explosions of extraordinary violence”(USGS). Since Yellowstone is a caldera, it means that there had been previous volcanic eruptions in this area and in this case two eruptions. The first explosion happened over 2,000,000 years ago because the composition of the magma contained vast traces of explosive matter that caused the eruption (USGS). The second incident happened around

The total estimated repair costs of the one eruption was ≈1.1 billion dollars. 1.1 billion dollars is a lot of money. In fact, the damages cost more than what Trump used for his campaign. Before MSH erupted, the volcano was an almost perfect cone, until it erupted and the whole North side exploded, lost 1,300 feet of elevation. 4 billion board feet of lumber was destroyed. The mudslides were no better, mud came flowing from the volcano at 50mph to 80mph and destroyed everything in its path.

- It is highly explosive due to the magma it produces, dacite. It needs large amounts of pressure to release it.

The Mexican volcano experienced its largest eruption in 1913, which lasted for 4 days, and formed a crater 300 meters in depth (http://volcano.oregonstate.edu/colima). Experts show concern that the volcano is exhibiting many of the

People are affected by lava and ash. Lava will burn you and you cannot stop it. Ash can get in your throat, which is harmful to breathe. People that live near a volcano u can be killed instantly. Also ash can block the sun plant cannot grow. Volcanoes helps soil and plants to grow.

Ash plumes and steam rose into the bright blue sky as the underground earthquake shook the land and rattled windows all across the eighteen mile town. As the jet circled the island, in view of lovely beaches and emerald water, looming over this lush paradise was the screaming volcano. Volcanos erupt when the pressure inside of them becomes so great that the magma surges up and forces its way out. An exploding volcano can rip apart a mountain in just seconds, when the eruption is over, a landscape is changed forever. The united states is home to more volcanos than any other country except Indonesia, and Japan. The majority of these volcanoes are in Alaska. Until recently, there was no way to predict when a volcano would blow, although volcanoes give off many warning signs before they erupt. Including smaller earthquakes beneath the volcano, slight inflation, or swelling. The rising magma eventually causes the solid rock to break, sending earthquake signals. Most volcanoes give warning signs beginning weeks or months before they blow (Lindop).

Volcanic eruptions are a constant issue. There are around 50 -70 eruptions every year with some volcanoes erupting more than once. Around 35 people die every year from volcanic eruptions along with an average cost of damage of 98,992,000. I believe that with a little math that these numbers can go down. Issues with volcano causing so much death is more of the debris that comes out of it if we could estimate the distant that this debris could travel then we would simply need to change the areas that we build cities and how far we would need to evacuate in a sudden emergency. This will include the ideas of projectile motion, angular projectile motion, Geometrical estimations. For this example, I will be using the volcano Mount Vesuvius. This volcano is known best for the destruction of Pompeii and villages that surrounded it. This eruption works the best due to the easily known eruption and the easily measurable distances from Pompeii to the center of Mount Vesuvius.
