Mount Bona and Mount Churchill is one of the greatest mountains in Alaska. Also it is the fifth highest independent peak in the United States. The eruption occurred around 800 AD in Wrangell-St. Elias National Park Alaska, U.S. This two volcanoes is more than 15,000 feet high, and permanently covered with ice and snow. Also 1250 years ago, Mount Churchill erupted which blew the lid off the mountain, and carried the ash into the southwest Yukon. It called White River Ash, and it covers almost 600,000 square kilometers in Alaska, the Yukon, and the Northwest Territories. If you was closer to the volcano you will be dead because the ash can be 60cm thick. This is very dangerous. Do you know that Mount Bona named by Prince Luigi Amedeo, Duke of the Abruzzi in 1897. …show more content…
Many people climbed on this two mountains but the first three people was Allen Carpe, Terris Moore, and Andrew Taylor. When this two volcanoes erupted it spreaded the ash from Canada to Germany. Moreover, Mount Churchill or Mount Bona is a composite volcano and composite volcanoes have a second volcano on the side. So there are two volcanoes on one mountain. This means that this two volcanoes consume the same magma. It does not tell how many lives were lost. The damage that this two volcanoes did is not so much because it happened so long ago that scientist cannot find. Mount Churchill’s eruption was the biggest or largest eruptions in North America in the past 2,000
Many of us know Mount Shasta to be a beautiful mountain and a popular tourist location in California. However, this mountain is much more than that, this mountain is actually a volcano. Volcanoes come with a number of hazards and a volcano of this size is of no exception. Previous eruptions on Mount Shasta have given us an idea of the power this volcano has and the damage it may do. With this information scientists are able to predict what may happen should another explosion occur.
When riding dirt bikes or any type of off-road vehicle it is some of the funnest time you will ever have. Sometimes it’s just a time to have fun and hang out with your friends but the others time its for racing and be competitive.But it all come down to what you enjoy,I like to do both.This is can be fun with your family,you can go to race and be competitive,and the most funniest part is when you are going fast and you have to keep from wrecking and get hurt.

Mauna Loa is Earth’s largest volcano and most massive mountain as it takes up nearly half of the flourishing landscape of the island of Hawai’i. This island is actually made up of five volcanoes, Kohala, Mauna Kea, Hualalai, Mauna Loa, and Kilauea, all in such close proximity that they fused together to form one whole island. Mauna Loa is located in the south central area of Hawai’i, in the Hawai’i Volcanoes National Park and its coordinates are 19°5' N, 155°6' W. It is 13,680 ft above sea level, but if one measures from its true base on the ocean floor, it is estimated to be 30,080 feet tall. Its name is quite fitting as it means “Tall Mountain”.
Helens tallied up to be the most deadly and destructive eruption the United States had ever seen. “Approximately fifty-seven people were killed directly from the blast and 200 houses, 47 bridges, 15 miles (24 km) of railways and 185 miles (298 km) of highway were destroyed; two people were killed indirectly in accidents that resulted from poor visibility, and two more suffered fatal heart attacks from shoveling ash (Wikipedia 3)”. Just when it seemed the nightmare was over a second eruption occurred the following day. A quarter of the lava was fresh, and included ash, pumice, and volcanic bombs, and the rest was older molten rock. “The removal of the north side of the mountain (13% of the cone 's volume) reduced Mount St. Helens ' height by about 1,280 feet (390 m) and left a crater 1 to 2 miles (2 to 3 km) wide and 2,100 feet (640 m) deep with its north end open in a huge breach (Wikipedia 3)”. The downwind of the eruption also destroyed many agricultural crops such as wheat, apples, potatoes, and alfalfa. Overall Mount St. Helens was a major blow that cost the US 1.1 billion dollars, and struck fear into the hearts of all of America on May 18th,
What is a super volcano, what is a volcano? A volcano itself is a hill or mountain with vents to the crusts of the earth that let magma sit under or in the mountain. “A super volcano is any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1,000 km3 (240 cu mi). This is thousands of times larger than normal volcanic eruptions. Super volcanos are on a much bigger scale than other volcanoes. Unlike composite volcanoes, with their steep sides, they are difficult to spot.” (Internet Geography, geography.learnontheinternet.co.uk) An average volcano in the world would just cause local damage, but this super volcano could end life on earth. Not just with the eruption but the ash would cause a volcanic winter blocking the sun to long and then even more the ash would choke everything out and collapse roofs. Yea Rainier would kill thousands of people, but Yellowstone would literally kill billions plus of people. In comparison, Rainier is a little fly and Yellowstone is a Griffin {The big eagle lion bird thing}. Yellowstone has the capability to erupt 1,000 times stronger than Rainier ever could.
Mount Tambora, located on the Island of Sumbawa, Indonesia is classified as a Stratovolcano. Also known as a composite volcano, Tambora is a tall conical volcano (cone like structure) where layers of the walls are built by hardened lava and volcanic ash. The term composite is used to describe the volcano due to the composite layered structure built from sequential outpourings of eruptive materials1. Among the most common types of volcanoes, Tambora also shares its destructive prowess with best-known volcanoes such as Krakota (1883) and Vesuvius (79 A.D). The Island of Sumbawa is located in the middle of the Lesser Sunda Islands chain (a group of islands in the southern Maritime Southeast Asia) and is in the province of West Nusa Tenggara3. A map of Mount Tambora is shown in Figure 1 to provide a better perspective of its location. Interestingly enough, Tambora forms its own peninsula on Sumbawa, known as the Sanggar Peninsula. In April of 1815, after years of dormancy, Mount Tambora erupted with great intensity, approximately 7 on the volcanic explosivity index, which is shown in Figure 2. It has been estimated that the eject volume of Tambora was 160 cubic kilometres, which represents the largest volcanic eruption in recorded history. The death toll has been projected to be at least 71,000 people, of who over 15% were killed directly from the eruption1. The remaining 75% have been thought to succumb to starvation and disease, as the eruptive fallout decimated the agricultural industry in the region. Following the eruption, a volcanic winter ensued. As sun become less abundant due to clouds of ash, crops and livestock perished. Please note that all definitions appearing in the footnotes are either taken from already referenced so...
The eruption on Mount Saint Helens has a specific cause and comes with many effects. A multifold of people would say that the “mountain looked like the site of an atomic blast” (Bredeson 30). That is a very accurate depiction as it took great power to inflict as much damage as it did. The reason for this impressive amount of force is that when magma is built up with pressure and an earthquake hits, the pressure gets magnified and the volcano explodes (Lewis). This is exactly what happened inside Mount Saint Helens. Furthermore, it has been revealed that “The earthquake that triggered the explosion was a 5.2 on the Richter scale” (Gunn 559). The earthquake to the magma can be compared as a match to gasoline. Even though the earthquake was not huge, the scale of the eruption was much greater than that of the earthquake (Gunn 560). The earthquake was only the trigger that allowed for more devastating things to occur. Thirteen hundred feet of the volcano were lost in the explosion followed by landslides, mudslides, and lava flows...
The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
1. 1. Mount Unzen, erupted in 1972. Its located in Japan near the Shimabara Peninsula. The earthquake accompanied by an eruption, triggered the collapse of the lava dome. Which then created lava deposits, that created a landslide. The landslide went through the nearby city of Shimabara. Then out to sea, creating a tsunami that tore through two cities and back to Shimabara. Approximately 15,000 people was killed, making it the deadliest volcano in Japan's history. Many of the deaths are due to the tsunami. The eruption caused Plants, animals and aquatic life to be threatened. However, Japans soil is rich, therefore the plants can grow back quickly. Other dangerous effect of this volcano are due to the ash that the wind carries to nearby countries and cities. When the ashes are inhaled it may cause illnesses.
The Mauna Loa volcano is located in Hawaii and means "Long Mountain" in Hawaiian. It is a giant, basaltic shield volcano. It is one of the largest volcanoes and mountains in the world and has been called the "monarch of mountains". It has an estimated volume of 9,600 cubic miles and takes up half the land of Hawaii. It extends about 120 km starting from the southern tip of the island to the northern region. It is 97 km (60 miles) long, 48 km (30 miles) wide, and is 8,742 km (28,680 miles) high from the base on the sea floor to the top. The slopes are steeper than 12 degrees and about 4 degrees at the top of the volcano. Mauna Loa formed about half a million years ago and in the middle stages of forming into a shield volcano where lava flows to form a sloped and broad flat domed volcanic cone. Along with Mauna Kea, the Mauna Loa volcano is responsible for the creation of the Hawaiian Islands. Mauna Loa has erupted thirty-three times since 1843 and is known as one of the most active volcanoes in the world today. The last eruption was 1984 and lava flowed within 4 miles of the city of Hilo. This shows that it is dangerous to live anywhere near Mauna Loa and that it poses as a threat to anyone living near it because it has a very high possibility of erupting within a very short span of time. Below is a picture of Mauna Loa taken from a bird's eye view.
As the plate subducts under the North American Plate it pushes up continental rocks forming a volcanic arc, a line of volcanic mountains occurring over a subduction zone, hence the Cascade Mountain Range. There are many National Parks and Monuments located in these volcanically active areas. There are four National Parks and many National Monuments located in the Cascade Mountain Range. Mount Rainier National Park hosts the tallest and still active volcano in the Cascades, Mount Rainier. In 1980 President Regan declared Mount St. Helens Volcanic National Monument in order to give scientists a chance to study the devastation and recovery from the event. These parks and monuments offer exciting scientific evidence of how the geological process works and I believe that if the public is knowledgeable about the safety precautions and possible ramifications after a seismic or volcanic event, it should be up to the public to make an informed decision whether they want to live in or near the danger
In 1952, the volcano stood 424 meters high and had damaged a significant amount of land surrounding the volcano. Two towns were destroyed
The general survival of the human race is always our main priority, whether it’s our own, a stranger’s or a loved one’s we have the protective urge built in. So when near dangerous areas we are always extra cautious of our surroundings. This protectiveness and cautiousness of our surroundings can lead us to be afraid to take risks and actually visit many places with dangers that are otherwise beautiful. One of these avoided dangers is an active volcano. Whether you live near one or are a tourist, being near an active volcano is scary especially if you don’t know how to keep safe if there is an eruption. Luckily there are some general tips to survive that everyone can follow. First, it must be understood that there are other dangers an eruption can cause than the main thing. Some of these are mudflows-dirt and ash mixed with water heading down the volcano at extreme speeds-, flash flooding-if there is rain or rivers near the volcano-, wildland fires- lava and magma can cause flammable objects to burst into flame. If these objects are in a forest, fires can wreak havoc in the wildland- and hot ash flows- also known
