50to60 Volcanic Eruption

Assess the extent to which primary rather than secondary impacts are the more serious effects arising from volcanic eruptions. (30 marks)

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

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

In these eruptions, instead of the mixture of gas and ash flowing upwards, it flows outwards and hugs the ground. These eruptions are extremely dangerous.

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

Volcanoes have existed on planet Earth since the beginning of time. It is likely that over

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.

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

Numerous major and minor earthquakes can warn of a volcanic eruption (USGS, 2015). A volcanoe can wipe out miles of homes and wilderness in the surrounding area. To summarize a volcanoe is a dangerous natural disaster caused for an accumulation of pressure and the movement of tectonic plates.

The active volcano that I chose to research is Popocatepetl volcano. Popocatepetl volcano is an active volcano located in Mexico. The volcano is oftentimes referred to as “El Popo” by many Mexicans. El Popo is a composite cone volcano. Being a composite cone volcano, El Popo is characterized by a steep cone shape, which was created by many composite layers of material pouring out over numerous eruptions. The lava that comes out of El Popo is extremely viscous. The highly viscous lava does not travel very far, and typically cools down rapidly. Scientists believe that El Popo is about 730,000 years old. It has erupted more than 15 times since 1519. In 1994 El Popo produced gas and ash, which caused nearby towns to evacuate. The toxic

Some of them will threaten not only natural environment but also human’s life. Firstly, it produced the pyroclastic flows which include volcanic ash, lava flows, hot rocks (USGS). In the class lecture, it states that this type of volcano can move a hundred miles away and the high temperature of lava can kill people near the eruption area. Secondly, when the small summit explosion happened, it created the “lahar” since it melted the snow and became the mudflow (Geology). Thirdly, the abundant volcanic ash will also disturb the normal aviation work. The tiny particle of the ash could get in the engine and damage the

Volcano eruptions happen more often that you know it. They even happen in Alaska. Earlier this year a volcano in Alaska had erupted. This was Pavlof Volcano. This massive eruption had a large cloud of ash and debris more than 7 miles into the air. Pavlof Volcano is 625 miles southwest of Anchorage. Lava shooting out of the volcano was seen by many people near the area. Strong winds had also carried a lot of ash and debris throughout the interior of the state.
