Mt St Helens Research Paper

Second of all, according to History.com, the city was buried by all of the ash from the volcano, dust poured across the land like a flood. The population decreased by about 15,000 people, the gas is what killed the most. Last of all, the city was destroyed by rocks that built up to 8.2ft, it was so heavy it collapsed on roofs destroying peoples homes, trapping people inside. Gases and ash were about 570 degrees fahrenheit which killed many people because it was that hot. Effect on people, effect on city, and how the city was destroyed are all interesting facts about the magnitude of the eruption in

On May 18th, 1980, Mount Saint Helen, a volcano in Washington erupted majorly. The eruption is the most studied volcano eruption. Mt. St. Helen was known as one of the most prestige volcanoes in the Cascade Range before its eruption on May 18, 1980. The eruption made a big blast that destroyed the northern part of the volcano, crushing millions of the trees below the mountain.

On May the 18th 1980, Mt Saint Helens in Washington State, United States of America erupted covering surrounding areas in ash, mud, toxic gases and lava. Mt Saint Helens is one of many active volcanos in the Cascade Mountain Range that runs along the Pacific Coast of the United States of America, a part of the Pacific Ring of Fire, named due to the many active tectonic plates in the region. The blast devastated an area of 20 square km. Within 10km of the summit, were there had previously been dense forest, no trees remained, beyond this area all trees were blown down. A further 600km2 was covered in ash and debris.

The bomb almost exactly hit it’s mark. It was more than 9,000 pounds and uranium 325. The bomb exploded 2,000 feet above Hiroshima. The blast equaled to 15,000 tons of TNT. It destroyed 5 square miles of the city (“The Atomic Bombings of Hiroshima and Nagasaki”).

In San Francisco on April 18, 1906 at about 5:13 am a HUGE earthquake hit recorded as a 7.7-7.9 . Damaging buildings from left to right. Many poorly structured buildings collapsed causing 500 million dollars in total damage (1906 money) translated to about 8.2 billion dollars today. It was recorded that most buildings immediately caught fire which trapped the victims, about 25,000 buildings were burnt down from the fire, a total of about 490 blocks.At around 8:14 a Major aftershock hit making even more damaged building collapse. The earthquake and fires in San Francisco were recorded to be the worst natural disaster in U.S. history.

This flood is still the biggest and most destructive flood recorded. It had so much damage that there were 300 people who died from the disaster. The water covered 17 million acres causing 236 million dollars’ worth of damage. It was a strong flood, “it was like facing an angry dark ocean. The wind was fierce enough that that day it tore away roofs, smashed windows, and blew down the smokestack- 130 feet high and 54 inches in diameter- at the giant A.G Wineman & Sons lumber mill”

S. President Harry Truman informed the world that an atomic weapon had been detonated on the Japanese city of Hiroshima. Nicknamed Little Boy, the bomb with a power of over 20,000 tons of TNT destroyed most of Hiroshima, killing an estimated 130,000 people. Three days later in August 9, a second bomb nicknamed Fat Man was dropped on the Japanese city of Nagasaki destroying most of Nagasaki and killing roughly between 60,000-70,000 people. Obviously, the bombs have oppose meaning to Japan. The government of Japan spend over 25 days to clean the corpses which dead in this cruel bomb.

In 1980, Mt. St. Helens in Washington state erupted, leaving ash everywhere; demolishing and exterminating all plant life. These Geo processes can cause land to rise or sink. One epitome of these are the islands of Hawaii. Hawaii was molded from underwater volcanoes.

Valdivia, Chile, 22 May 1960 (9.5) This earthquake killed 1655 people, injured 3000 . It caused US$550 million damage in Chile, while the tsunami that it spawned caused deaths and damage as far away as Hawaii, Japan and the Philippines. The 'rupture zone ' of the quake was more than 1000 km long. Two days after the initial quake, the nearby volcano Puyehue erupted, sending ash and steam up to 6 km into the atmosphere over a period of several weeks.

In fact, a mushroom cloud reaching 13, 716 meters and a 3.2 kilometer long firestorm appeared. The effects of the blast were absolutely terrifying. Above 60, 000 of Hiroshima’s 90, 000 buildings were completely destroyed, all objects made from metal, clay and stone melted, and many faced severe health problems from exposure to high levels of radiation. In terms of deaths, approximately 70, 000 people were killed instantly from the explosion, and just as many died five years later. In summary, the city was left in little more than ashes, with two-thirds of it destroyed.

The fire and explosions lasted for two days and were felt as far away as Newark. More than 30 million pounds of explosives were set off, damaging many houses and killing as many as 87 people.Damage was estimated at $18 million. An article in the New York Tribune described the destruction: “Besides the heavier blasts, caused by entire buildings exploding, there was the additional horror of shellfire. Hundreds of loaded shells were set off by the flames and soared through the air like monster rockets, exploding in the streets and over the roofs.”Damage was estimated at $18 million. An article in the New York Tribune described the destruction: “Besides the heavier blasts, caused by entire buildings exploding, there was the additional horror of shellfire.

In the city for many years, the people of Pompeii did not know that that Mount Vesuvius (the volcano) would erupt. Even seeing smoke coming out of the volcano they still did not know what the future would hold. When Mount Vesuvius was erupting, every second 1.5 million tons of ashes and rocks shot out of the volcano. Rocks that would shoot out of the volcano would reach about twenty miles high. Researchers estimated that 1,600 people died during Vesuvius 's eruption.
