Essay on Mount Etna in Italy

A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also

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.

The remote location and weather with very limited visibility, just a few inhabitants, may and probably have allowed some of the older eruptions to go unconfirmed. (Before their were not many people living in this area)

Usually, many earthquakes in succession can warn of a volcanic eruption. Warning systems for volcanoes are based on the possibility of a hazard. The volcanoes are classified based upon the likeliness of an eruption. An active volcanoe is currently erupting or expected to erupt in the near future. Dormant volcanoes are inactive, but they are likely to erupt sometime in the future. An extinct volcanoe is unlikely to erupt again. Even though a volcanoe is not expected to erupt, it could suddenly become active. Volcanoes are unpredictable because almost any of these mountains could erupt again. There is no current way to ensure that a volcanoe will not erupt. To prepare for a volcanoe families should have an emergency supply kit that includes food, first aid kits, and other supplies. Also every family should have a plan to stay safe during any natural disaster. The best way to stay safe from a volcano that is likely to erupt is to evacuate (Anderson, 2012). 260,000 have died within 300 years from different volcanoes and their aftermath (National Geographic, 2016). Volcanic eruptions can be accompanied by other natural disasters including mudflows, flash floods, rock falls, acid rain, and tsunamis. Devastation from a volcanoe can stretch for hundreds of miles (Anderson, 2012). Hence, volcanoes are unpredictable disasters that everyone near a volcanoe should be prepared for, even if it is not expected to erupt

Some scientists estimate that the last eruption of Mt. Scenery probably took place just before the European settlement of Saba island, dating back to about 1640. Presence of hot springs or heated groundwater indicates

Volcanoes are one of the most intimidating natural processes that occur on this planet. Usually they are associated with danger and chaos. Volcanoes are characterized by both their composition and eruption types. In this paper we will be exploring the similarities and differences between three infamous volcanoes, Mt. St. Helens, Mt. Kileaue, and the currently relevant Mt. Agung.

Helens was a huge eruption that happened May 18th, 1980. 57 people died from the smoke. By April it was growing 5ft per day. The mushroom clouds of ash and gases more than 12 miles into the air.” states livescince. “The shock wave went 19 miles” state's fs.usda.gov. Such pulse indicated magma was on the move. On May 18, there were hundreds of earthquakes that day. The eruption lasted 9 hours. The Mount St. Helens erupted at 8:32 A.M. It went as high as 1,300 feet (396 meters). Biggest eruption over 100 years. “The first eruption of steam from the summit sent a column of ash, snow and, steam 6,000 sent into the air”, livescince.gov There were a lot of things going on that day and

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.

The advent of the eruption of Mount Tambora in April , 1851 was probably the most destructive eruption ever recorded in the history. Tambora’s catastrophic eruption has effected the surrounding area, the local people and their life styles enormously. It emptied about 50-150 cubic km of magma and measured 7 on the VEI Scale, it also ejected large amount of ash and aerosols into the stratosphere.

Chapter 3, as well as the article “A Fresh Look at Mount St. Helens” is very interesting. Chapter 3, section 1 covers the Earth as a system, the structure of the Earth, and Earth affects like earthquakes, or volcanic eruptions like the one on May 18th, 1980 in Washington State. Mount St. Helens was once covered with vegetation and small ponds. It has been nearly thirty years since one of the largest eruptions ever observed. The explosion blew the side of Mount St. Helens and lasted nine hours. This article relates to chapter three a lot. This volcanic eruption transformed the landscape and environment extremely. Mount St. Helen was once 9,677 feet tall and after the violent eruption it trimmed 400 meters off the top.This eruption damaged enough

On the 5th of April, 1815, after laying quiet for over 5000 years, the first eruption began, lofting a volcanic column 25 km (15.5 miles) into the sky. This initial eruption was heard over 1000 km away.

#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,

Tilling (1997) reported that earthquakes began on March 16th, including one that was 4.2 (Richter Scale) on March 20th. Earthquake activity increased after this and following an explosion around 12:36 p.m. PST on March 27th, Mount St. Helens began to eject ash and steam. The crown of the ash column ascended to about 1800 metres above the volcano. Mount St. Helens spewed ash and steam in bursts ranging from a few seconds to several minutes until April 21st. Intense earthquake activity persisted

One of the volcanoes that are looked to for answers on modern day volcanic eruptions is Mount Vesuvius which is located in Pompeii. This particular volcano erupted in 79 AD. Scientists and archaeologists believe that approximately 13 to 20 feet of ash and lava were sent into the atmosphere and buried the cities of Pompeii, Herculancum and many other cities in the vicinity. Over 1500 years would pass before the stories of this volcano and the people that lived there would start surfacing.

Mount Vesuvius is one of history’s most recognizable Volcanoes, as each of its eruptions have gone down as a significant event in geologic history. The events that transpired during and after these eruptions have shaped the way scientists and people view the sheer power that these volcanoes possessed. This report will take a look at Vesuvius’ most prolific eruption in 79 AD. The geologic setting of the mountain, precursor activity, and the impact the eruption had on the surrounding populations and towns will all be detailed. Along with these details, this report will also look at the further history of Vesuvius’s explosive past by detailing its eruption cycle. Finally, the current state of Vesuvius and the possible danger
