The Importance Of Mount Fuji

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.

Mount St. Helens Location: Washington, United States Latitude: 46.20 N Longitude: 122.18 W height: 2,549 meters or 8,364 feet - 9,677 feet before May 18, 1980 Type: Stratovolcano Number of eruptions in past 200 years: 2-3 Latest Eruptions: Between 1660-1700, around 1800-1802, 1831, 1835, 1842-1844, 1847-1854, 1857, 1980-? Present thermal activity: strong steaming Nickname: Mount Fuji of the West Remarks: continuous intermittent activity since 1980 with occasional eruptions of steam and ash; occasional pyroclastic flows; intermittent dome forming. MSH is considered a young volcano that developed over the last 40,000 years and is one of the most active volcanoes in the Cascade Range. Geologists predicted that the

Mount Vesuvius, like most volcanoes was created through the interactions between continental plates. Mount Vesuvius was formed 17,000 years ago through the convergence of two tectonic plates, the African plate and the Eurasian plate. Vesuvius is located above a subduction zone in which the African plate is being subducted by the Eurasian plate (Ball). The African plate has been subducted at a rate of about one inch every year. This type of interaction between converging plates is responsible for creating volcanoes (Figure 1). This created a submerged deep ocean volcano in the Bay of Naples. Later, Mount Vesuvius emerged from the ocean as an island. However, over time it was connected to the mainland due to buildup of deposits from its eruptions.

What is a volcano: A volcano is a mountain created by the earth. It also creates a hole where molten rock (lava) erupts. A volcano is filled of magma but when the magma erupts and is out of the volcano it is now called lava. When a volcano erupts it fills the air with lava fragments. A volcano can cause a lot of destruction like tsunamis, flash floods, mudflows, rockfalls, and earthquakes. Most volcanoes are located where the tectonic plates meet. Most

Ask anyone in the Pacific Northwest to name a volcano in the area and you will most likely get the response of “Mount St. Helens”. There is good reason for this particular volcano to have gained such a great reputation for itself, and that is the eruption which occurred in 1980. Beginning in March, new systems of seismographs were being implemented to track the size of earthquakes that were happening in the St. Helens area. Earthquakes were recorded up to three times a day almost daily and on March 27th, an official warning was sent out as one of the quakes caused a stream of ash over 6,000 feet into the air. On the morning of May 18th, 8:32am, an earthquake measuring in at a magnitude of 5.1 on the seismograph signaled the beginning of the eruption.

The volcano is actually a volcano inside of a volcano. When scientists studied the structure they pointed out its two different cone shaped tops spread about three miles long of a valley in between. They then stated that it was two volcanoes one inside the other in some geographic way. The eruption in 79AD was the first recorded eruption for history. Mount Vesuvius is in the Campanian volcanic arc along with Vulcan and some others

Volcanos are an amazing destructive force. There are four different types of volcanoes. There is Cinder cone, Stratovolcanoes, Shield volcanoes, and Lava domes. They are vents in the earth that have

When Mount St. Helens erupted it took lives and destroyed at least fifty miles of the surrounding area. A volcano is a mountain or hill where a vent forms in the earth’s crust, letting ash, lava, and steam escape. Mount St. Helens included many details common to volcanic eruptions, caused damage and destruction, and how the area has recovered.

A volcano is a mountain built when magma rises from Earth's interior to the surface of the Earth.Volcanoes erupt when the pressure of the melted rock inside becomes so high that it blows through the solid surface of volcano. This explosion leads to many economic difficulties just like it did when Mount St. Helen exploded. It is a devastating event and clouds of ash, dust, and gases flowed into the environment. These fumes can be difficult to breath in and the damage it can cause wildlife is also

There are basically two types of volcanos: the active and the inactive ones. And just like in the movies, once the volcano erupts, its lava melts everything

Dr. Richard Waitt inform us that the eruption on May 18, 1980 surprise scientists because they had a lot of data that they collected and that data didn’t indicated that an eruption was going to come on that day. When it blast in May 18, 1980, it destroyed everything in their path. For example, a total of 57 people were killed, thousands of deer, elk, bears, and other wildlife were killed, and the eruption had cut open a 2,000-foot-wide crater in the top. The landscape was unrecognizable by geologist who had spent about two months before the explosion on May 18 working up the volcano every day. It is interesting to know that discolored rock in the valley and in the crater wall were evidence that the mountain was decaying before the eruption.

Before May 1980, Mount St. Helen in Washington State ha been quiet for over a hundred years. It had been calling "the Fuji of America " because it's symmetrical cone resembled the famous volcano in Japan. It's massive eruption on Sunday, May 20, 980, changed that shape. Mount St. Helens lost 3.7 billion cubic yards of rock. Volcanic ash was send fifteen miles into the air, and very hot winds blew in all directions. Two hundred thirty square miles of forest were flatten. Seventy percent of the snow and ice on the mountain melted, causing an enormous landslide of mud, volcanic ash, rocks, and trees to speeding down the mountain at 500 miles per hour. In the eruption, fifty-seven people lost their lives, some as far away as thirteen miles from the mountain. Most of them were scientists, loggers, and journalists.

The Hawaiian volcano is a shield volcano; they are the oldest continental regions of earth. They may even be the remains of ancient shield volcanoes. A shield volcano is tall and broad with flat, rounded shape. The Hawaiian volcanoes are built by countless outpourings of lava that advance great distances from a central summit vent or a group of vents. Extensive study of the Hawaiian Islands revealed that they are constructed of a myriad of thin basaltic lava flows averaging a few meters thick intermixed with relatively minor amounts of pyroclastic ejected material. During eruptions these outpourings help keep these volcanoes safe. When these volcanoes erupt lava fountains out form the volcano and is hot liquid lava is thrown into the air but usually not very high. The lava normally flows easily, and does not explode. These volcanoes also only explode if water some how gets into the vent. Mount St. Helens is composite volcano, which are also known as strato- volcanoes. They are tall, symmetrically shaped, with steep sides, sometimes rising 10,000 feet high. They are built of alternating layers of lava flows, volcanic ash, and cinders. The large and generally cone-shaped volcanoes form along plate boundaries called subduction zones where one of the earths plates melts as it falls back into the earth`s mantle. The eruptions are called explosive, and effusive, because vast amounts of gasses are thrown into the atmosphere, and the lava explodes and is vicious.

First and foremost, this whole mess began around March 20 of that year when an atypical earthquake shook up the mountain range for the first time in hundreds of years. As the days went on, the earthquakes came more often and more rampant. A bulge sprouted on the side of the volcano, growing
