Mount Saint Helens and Mount Vesuvius are volcanoes that have erupted they are both different and also the same here are some facts, similarities and differences of both the volcanoes. There are a lot of similarities of these volcanoes here are a few, they are both volcanoes, made a huge eruption, very destructive, damage, a huge black cloud, an earthquake before the eruption. Some of the ruins are still there today. The eruptions were very different too. Here are a few differences of Mt. St. Helens, it was 9,600 feet tall in a symmetrical cone shape, it erupted on May 11 1980 at 8:32am, the eruption blew the whole side of the mountain off and the eruption removed the upper 1,300 feet off forming a horseshoe shaped crater, it
In March 18, 1880 Mount St. Helens there was a catastrophic eruption that caused a huge volume of ash; the ash plume would be over central Colorado within 16 hours. After years of dedicated monitoring (knowing where to volcano is, unlike an earthquake not knowing exactly where this geological even is exactly) there was been increasing accuracy in forecasting eruptions.
To start, these names are the names of two big volcanos, both in Washington State, both deadly, but on different scales. Mt. Rainier’s last eruption was 150 years ago. Yellowstone’s last eruption was 640,000 years ago. Yellowstone’s reputation of being the ultimate super volcano versus Mt. Rainier, the most dangerous volcano in the country. The difference between these volcanos is looks, damage, stability and tourism.
Lassen Peak and Mount St. Helens are the only two volcanoes in the contiguous United States to erupt during the 20th century.
Spain and the Ming Dynasty were places on Earth in two very different locations. Yet, somehow they had been similar. The rulers had killed or expelled people that disagreed or they both just had their ways of organizing. But there seemed to be more differences. Spain had conquered the Americas and did not separate the state from the church and the Ming didn’t expand that much, and didn’t involve religion into politics. Thus, Spain had more larger goals towards imperialism, Christianity, and keeping the country in a “pure” state with only hereditary Christians, while the Ming Dynasty focused more on unity, acceptance of all religions, and keeping the court as balanced as possible.
Helens is located in Skamania County, Washington at a latitude and longitude 46°11′28″N 122°11′40″W. Mt. St. Helens is a stratovolcano volcano that has an elevation of 2,549m (8363 ft.). The last eruption was 36 years ago and has erupted numerous times within the last 100 years. The eruptions are explosive with ash and pyroclastic flows. Mt. Helens erupted on May 15, 1980 with a VEI 5 rating. It was the only large eruption to happen in the contiguous 48 states since 1915. Fifty-seven people were kill, along with several farm animals. Two hundred miles of land and trees were obliterated. This area is now called the Mount St. Helens National Volcanic
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...
57 people were killed, and 200 homes, 47 bridges, 15 miles (24 km) of railways and 185 miles (300 km) of highway were destroyed. The eruption blew the top of the mountain off, reducing its summit from 9,677 feet to 8,364 feet in elevation and replacing it with a mile-wide horeshoe-shaped crater. Like most of the other volcanoes in the Cascade Range, St. Helens is a great cone of rubble, consisting of lava rock interlayered with ash, pumice and other deposits. Volcanic cones of this internal structure are called composite cones or stratovolcanoes. Mount St. Helens includes layers of basalt and andesite through which several domes of dacite lava have erupted.
On May 18th, 1980, one of the most prominent volcanic eruptions in US History took place in the state of Washington. Mount St. Helens had been dormant for almost 100 years before March 15th. On this day, two months before the eruption several small earthquakes shook the earth. This indicated a magma buildup below the surface, and the first minor event that would lead to one of the greatest eruptions the US has ever known. Following the first set of earthquakes, “Steam explosions blasted a 60- to 75-m (200- to 250-ft) wide crater through the volcano 's summit ice cap and covered the snow-clad southeast sector with dark ash. Within a week the crater had grown to about 400 m (1,300 ft) in diameter and two giant crack systems crossed the entire summit area. Eruptions occurred on average from
These differences are in the makeup of the volcano, the impact on society, and the eruption itself. Mount Saint Helens, used to be a wonder of the world, but now a damage site of what happened on May 18, 1980. Mauna Loa is a tourist destination and one of the most active dispensers of lava and magma in the world. As shown, these volcanoes can’t be more different. Yet, each volcano has been a culprit to destruction, and have similarities within themselves. This report has expressed many similarities and differences and brought facts and knowledge to the historical eruptions by these impressive and ancient structures of
As both the Roman Empire and the Inca Empire thrived during their different eras of time, they shared both similarities and differences in their forms of trade and technology. Both empires had a large network of roads, the difference between them was who was allowed to use them. In Rome anyone from nobles and famers could use them. But in the Inca Empire, only conquered people were given right to specific areas and barred from the network of roads. Rome hardly had any inventions theirs were mostly based on Greek inventions, while the Inca invented the Quipu to keep track of taxes and population. All in all they are very much different than alike. both Romans and Incas had roads to travel to far parts of their empires. Rome used the roads to
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Two people can be very similar, but different at the same time; take Marilyn Monroe and Helen of Troy for example. Marilyn and Helen both remain a mystery to the public eye. Marilyn’s mystery remains with the question of not only her lifestyle, but her sanity as well. Helen’s mystery is the question of her birth and the number of men she had wed. The women are both seen as a symbolic term of beauty.
1980 eruption of Mt. St. Helens and the 1991 eruption Mt. Pinatubo. (Ball, J. n.d.).
Firstly, I believe the eruption of Santorini was more powerful than first estimated, due to the presence of a shallow sea inside the Theran crater, with the volcano situated in the centre of that sea. (This is the theory of Professor Steve Sparks of Bristol University)
Mount Vesuvius is a strato-volcano consisting of a volcanic cone (Gran Cono) that was built within a summit caldera (Mount Somma). The Somma-Vesuvius complex has formed over the last 25,000 years by means of a sequence of eruptions of variable explosiveness, ranging from the quiet lava outpourings that characterized much of the latest activity (for example from 1881 to 1899 and from 1926 to 1930) to the explosive Plinian eruptions, including the one that destroyed Pompeii and killed thousands of people in 79 A.D. At least seven Plinian eruptions have been identified in
