Mount Etna Research Paper

With no prolonged periods of inactivity the volcano has continuously built up on itself. The last major eruption took place in 1790 and killed many people and animals, but numbers are unknown4. Starting in 1983 there was a chain of several eruptions that started and have yet to stop pushing lava through a lava tube till it reaches the Pacific Ocean. Over a span of twenty year the flow has

The aim is to identify and associate landforms, rock types and soils to the natural environment and its plants and animals and also to investigate the history of the local environment, comprising human impacts over the last 50 years. The impact of human alterations to the environment includes increased soil erosion and changes in river flows.

Of the handful of historic sites in Vermont that are connected to the War for American Independence,

The first recorded person in history to ascend Mt Druitt, an area in the relegated public squalor of Western Sydney, has also successfully reached the summit.

Voted the second most beautiful vista in America, Mount Washington is a well-known overlook of downtown Pittsburgh. Mount Washington, now a beautiful mountain with a tree covered Cliffside, was not always known for its sights. Many are unaware of the dirty environment that it used to be. Once known as Coal Hill, Mount Washington was the location of many coal mines. Back in the late 1800’s, this mountain was the source that fueled and built Pittsburgh. From the ravaging coal minds to the breathtaking Inclines, there is a lot of history that is hidden under the beautiful area which we now know as Mount Washington.

After more then 40,000 years of activity, one would expect that people would no longer live in the surrounding shadow of Mt. St. Helens. But regardless, many towns and cities sit inside of a zone that would face destruction if a large eruption took place. In 1980 Mt. St. Helens erupted and caused the loss of many lives and the destruction of thousands of miles of land and property. Following the eruption, the volcano has stayed extremely active. In 2004 it erupted again, building a new lava dome and sending ash and steam into the atmosphere. Since then, seismologists and volcanologists have recently discovered pockets of magma rising and that another eruption may occur soon. Even though the people of Washington know that an eruption could cause widespread devastation they continue with their lives, doing little to prepare for the potential disaster.

Mount Rainer is the 5th National park. This National park was established by an act of congress in 1899. This mountain was set aside to “protect areas of outstanding scenic and scientific value for the enjoyment of present and future generations”. In 1988, 97% of Mount Rainer was designated as wilderness.

In far Northern California, about forty miles south of the Oregon-California border, resides the second highest mountain in the Cascade Range and the fifth highest mountain in California. The Cascades are part of the “Ring of Fire,” which is a ring of volcanoes and earthquake sites, around the borders of the Pacific Ocean. Mount Shasta can be seen for several hundred miles and has struck viewers with its remarkable beauty since it was first seen. Mount Shasta towers at 14,162 feet, remains snow-capped throughout the year and is often shrouded in oddly shaped lenticular clouds, or fierce storms that hide it from view. It is awe-inspiring in its geography and geology,

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.

St. Helens. Mt. St. Helens has been the most frequent Volcano for the past 4000 years. Native Americans were also once living near the Volcano. Due to a much bigger eruption, 3600 years ago, the Indians abandoned their hunting grounds in fear of their lives. After the eruption ash rose 80,000 feet into the sky after just 15 minutes! In September of 2004 this Volcano started to erupt frequently once again until january of 2008! Thousands of birds, mammals, and reptiles died after the eruption. Within 3 minutes of the eruption lateral blast traveled at 300+ miles per hour and burned down 230 square miles of the forest that had surrounded the Volcano. Out of all the facts that I have researched these were the most interesting facts I had researched to conclude my

#5 The first eruption that took place that scientists believe was in 475 BCE but it was very vague since it occurred so long ago. The most commonly known eruption was in 1669 in which it killed over 20,000 citizens. The ash spread 100 miles away. Before the eruption an earthquake took place in 1169 killing an additional 15,000 people. It wiped out 14 towns and villages, leaving about 27,000 people homeless. It lasted for about two months. The last actual eruption happened on December 3rd 2015; however, no deaths were lost and it did not last very long (small). Etna's longest time it was fully active began in 1979 and went on for thirteen years. It is still active today but not as much as before. It contains many different types of volcanic igneous rocks including,

Mount Etna is almost twice the size of Mount Vesuvius, the volcano that destroyed Pompeii. Etna has four very prominent craters. There is the Bocca Nova and the Voragine, the central craters, and there is also the Northeast crater and the Southeast crater. Mount Etna once erupted in Roman times in the city of Catania. After the eruption taxes were cancelled for about ten years just so the town people could rebuild. Another

There are negative and positive social impacts. The negative social impacts are 200,000 people became homeless, 320,000 displaced and 278,000 people had to flee their homes. Also the evacuation areas were so overcrowded it lead to poor sanitation, serious diseases and no privacy. Some of the positive impacts is that the volcano brings jobs of the tourism industry and it also accompanied the medical use of hot spa water. In addition, the mud that resulted from the eruption was beneficial and promoted

The third possible strategy is to build a barrier. Back in 1983 when Mount Etna threatened the three regions in the province of Catania in Italy, they made three barriers in attempt to change the direction of the flow of the lava. The first barrier with a height of 18 meters and a wide of 10 meters was overwhelmed by the lava. However, the second and the third barrier blocked the lava from reaching the settlement
