A volcano is a large hill, with a crater or vent for lava to flow through. Volcanoes can have a lifespan of a couple months to a couple million years. They are one of the most dangerous natural disasters. An erupting volcano can cause other natural disasters. Such as tsunamis, flash floods, and earthquakes.
One of the most famous volcanoes is Mt. Saint Helens. This volcano is still active to this day. On may 18th, 1980 a huge volcanic eruption happened at Mt Saint Helens. The eruption was the most significant eruption in the contiguous 48 U.S. states. It has often been declared the most disastrous volcanic eruption in U.S. history. The eruption was followed by a 2 month series of earthquakes.
The eruption caused the north face of
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
Lassen Peak and Mount St. Helens are the only two volcanoes in the contiguous United States to erupt during the 20th century.
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.
Mount St. Helens is an active stratovalcano in Skamania County, Washington, in the Pacific Northwest region of the United States. It is located 96 miles south of Seattle and 53 miles northeast of Portland, Oregon. The mountain is part of the Cascade Range. It is most famous for a catastrophic eruption on May 18, 1980. That eruption was the most deadly and economically destructive volcanic eruption in the history of the United States. 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 horeshoeshaped crater.
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.
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...
Volcanoes have always been a mysterious wonder of the world. Volcanoes have shaped the landscape and the very ground that we all live on. People have written stories of their disastrous eruptions, and painted their marvelous shapes on canvas. The essay will outline some of the more famous volcanoes and how they have impacted are history. Mount Vesuvius that destroy the great city of Pompeii, Krakatoa they spewed deadly ash on small village town, and Mount St. Helen, the only volcano in my own country to every erupt during my own time period.
Deep within the Washington wilderness in the shadows of Mount St. Helen lies the infamous Ape Canyon. Upon these steep shallow cliffs, strange encounters have emerged over the past century. In 1924 a group of seasoned miners set out on a routine expedition searching for gold. However, what they encountered changed their lives forever. It was here that allegedly famous attack by a group of sasquatches occurred. In the short autobiography, I Fought the Apemen of Mt. St. Helens by Fred Beck, one of the miners, recollects his parties encounter with the beast.
Volcanoes. The naturally forming landforms that can look remarkably beautiful. Gentle slopes, or high rising heights with snow caps and greenery that seems to attract many tourists and sightseers around the world. These magnificent landforms can also cause major destruction and can produce forces that can explode, burn, and create a great deal of damage. Two of these extravagant wonders of the world is the Mount Saint Helens composite volcano in Washington, US, and the Mauna Loa shield volcano in Hawaii, US. These landforms have a eruption history of many colors. One has a great power in eruption, but another has a eruption that is quiet and gentle. In comparing these two volcanoes there are many likes, and dislikes, to consider. So the following
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Volcanoes can cause damage by spewing lava, but earthquakes before the eruption can also cause damage. These earthquakes open fissures and let magma out to the surface. When the magma exits these fissures, streams of lava up to hundreds of feet can shoot into the air. The picture below shows the lava erupting from the fissures created by the earthquakes in...
When the reservoir has formed, a substance is collected that will trap the volcanic gases. They form depressions in the ground and it is very hard to imagine the eruptions, explosions, car atrophic proportions that they cause. Super volcanoes produce vast amounts of ash and destruction. There are thousands of normal volcanoes around the world and at least 50 erupt every year. Vast clouds of ash are deafening sounds; it affects the climate on earth for many years and affects the agriculture colour.
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
On May 18th 1980 mt.st.helens erupted. My mom was looking out the window watching A huge cloud of ash coming towards her house. She remembers thinking it was like snow but dark. Her parents were watching the news. The news said that mt.st.helens has erupted and to bring inside anything outside that you want to keep. So my mom helped her dad bring in supplies from outside.
