Volcanoes

By: Temujin Tesvich

Introduction

Hollywood movies. Hollywood movies are said to be one of the best genres of movies around the world. It is best known for many of its particular sub genres and one of them happen to be disaster movies. It can be for all types of natural disasters. But I will be focusing Volcanoes in particular. I will be talking about it throughout the article.

Location of Volcanoes

Earthquakes and volcanoes are usually found in a ring called the ‘Ring of Fire’. The Ring of Fire is an area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. The Ring of Fire also includes many Earthquakes. The motion of the faults generates numerous small earthquakes, at any time of the day, most of which are too small to even feel. Below this paragraph, there are 3 photos indicating where the ring of fire and some other photos too.

The bad thing about the movie "Volcano" is that their are barely or even no volcanoes that are located in Los Angeles and to prove a point is that there is a Volcano in the middle of the streets in LA. Most of the Volcanoes are in California.

How do volcanoes erupt?

How?

Volcanoes erupt because of density and pressure. The lower density of the magma relative to the surrounding rocks causes it to rise . It will rise to the surface or to a depth that is determined by the density of the magma and the weight of the rocks above it.When it’s underneath the surface, the molten rock is called magma. When it reaches the surface, it erupts as lava, ash and volcanic rocks.

How do Volcanoes affect us humans and others


Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields.

Lava can kill plants and animals too. The Mount St Helens volcano in 1980 killed an estimated 24,000 animals including 11,000 hares, 6,000 deer, 300 bobcats, 200 black bears and 15 mountain lions.

Volcanoes can change the weather. They can cause rain, thunder and lightning. Volcanoes can also have long-term effects on the climate, making the world cooler.


For sure, one of the most dangerous effects of an earthquake is a Tsunami. Tsunamis are giant waves that can cause floods and in some cases may reach up to 100 feet in height. These deadly waves strike a great distance from the epicentre. Tsunamis often result from sub-sea faulting of ocean floor sending seismic shocks through the water and creating large waves of low amplitude but of long period, moving at 500-700 mph.

Case study

Mount St. Helens erupted on May 18, 1980. The volcano, located in southwestern Washington, used to be a symmetrical cone about 9,600 feet (3,000 meters) above sea level.Pyroclastic flows exited the northern breach and covered avalanche debris, lahars and other pyroclastic flows deposited by the May 18 eruption. At 7:05 p.m. on June 12, a plume of ash billowed 2.5 miles (4.0 km) above the volcano. At 9:09 p.m. a much stronger explosion sent an ash column about 10 miles (16 km) skyward. The Volcano when erupted, estimately killed around 57 people. In the movie, it killed many more when the volcano struck the cities

How does the movie "Volcano" differ from reality

What was wrong?


Premise: What if a volcano appeared and started erupting under a populated area like Los Angeles?

A greater problem is that they should have all died of massive bleeding in the lungs before they even had a chance to try to block the flow of lava. Ash is basically fine shards of glass. No one was wearing masks, so they were basically inhaling glass. For hours. Not one cough. No sneezing. No gasping.


They got the effects and how the volcano erupts right because its obvious how volcanoes erupt because of the magma flying out

Conclusion

In the article, I have explained a good amount of information about Volcanoes and the relationship between the movie "Volcanoes" and reality. The movies was pretty well done (Volcanoes) 1997. The movies did show the effects on how volcanoes can affect people around in the cities. But.. It is very unreliable how a volcano can be in the middle of L.A and that nobody could smell the fumes of the smoke because of the things that have been broken down (glass. wood, metal). In the beginning, 3 people have died, workers. So I think its half half 1/2. Overall it was an accurate movie.
