The Eyjafjallajökull Volcano

A hazard is a situation that poses a level of threat tolife, health, property or environment. The level of hazard posed by different volcanoes can very greatly, from a weak eruption with minimal impact that causes little damage, to a voilent and life threatening explosion. Most of the sixty-plus volcanoes that erupt each year are low risk, however a combination of factors can cause a volcano to be a serious hazard. The factors causing these variations will be explained in this essay.

Volcanoes can be found throughout the entire world and are formed when there is a rupture in the mantle of the Earth's crust. This effect allows the output of volcanic lava, ash, and various types of gases. These tectonic plate breaks are normal, the planet Earth is divided into 17 tectonic plates and consistently move against each other forming shifts from low to high intensity. It can cause displacement of earth or water.

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.

Volcanos are beautiful yet discursive. They may have different effects on towns but some are similar, and some are different. Some may have an effect on both people and cities and the people's mindsets may change on their beloved homes.

In the early 1900s St.Pierre on the French Caribbean island of Martinique was famous tourist destination.”It was known as the Paris of the west Indies”, and home to more than 20,000 people,Mount Pelee sits about 4 miles from St Pierre.On May 8, 1902 the volcano erupted. Sending a volcanic surge directly at St.pierre's at a rate of 420 miles per hour.Killing 30,000 people in its wake.National National Geographic News”Deadliest volcano of the 20th century, 100 years later””molly pell and channo wOodage for National Geographic News, 5-8-2”

Another physical factor is snow; if a volcano is snow capped, like Eyjafjallajokull, then the lahars and flash floods become a greater hazard. The flooding in Iceland in 2010 caused 700 people to be evacuated. Without the snow then lahars and floods may not be a problem at all.

Volcanoes are in fact important because without volcanoes the atmosphere wouldn’t have its oxygen rich properties. Many of years ago, Earth’s atmosphere was swarm with rock-forming minerals of the earth 's crust. During earlier volcanic eruptions many gasses enters into the earth atmosphere. Carbon dioxide, water vapor and many other gases

The Capulin Volcano interestingly enough, is apart of what's known as the Raton-Clayton volcanic field (RCVF), a collected scattering of other volcano's that stretch well over 7,000 square miles. Located in Northeastern New Mexico, the Capulin lies dormante, although some believe extinct, since it's last volcanic activity more than 60,000 years ago. Capulin underwent a rather large eruption that formed its current 1000ft cinder cone shape, which gave way to "a number of small lava flows and cinder eruptions [that] paved over the mound, steepening it's slopes"(NASA, 2016). The base was inital made from the hot ash, cinder, and rock debris of the eruption, and the lava flows themselves were "basalt, deriving from the melting of the mantle" (Sayre and Ort, 2011). Due to

Mauna Loa volcano. Mauna Loa is an active, large, and dangerous volcano in the world.this volcano can cause more than one damage. Mauna Loa affects people’s lives, and damages lands. Mauna Loa is a magnificent force of nature.For centuries Mauna Loa has captivated many discoverers and scientists all around the world.But some, however got injured by Mauna Loa and didn’t study its parts.One discoverer however actually discovered it somehow.This volcano is very dangerous and it can damage 1 small village.

The Raton-Clayton volcanic field is about 20 000 km2 in size, and has been active periodically for the past 9 million years. The area is filled with peaks, cones, and lava-capped mesas. The mesas developed as lava flowed into valleys and depressions, cooled off and formed a resistant top layer over sedimentary rocks. As the surrounding rock eroded, the lava protected the underlying stratigraphy from erosion. This caused todays topography, where that which was once the lowest point, is now the highest. There is some disagreement over why the volcanic field is here, one possible cause is that it is near the end of the Jemez Lineament, which has numerous volcanic centers along its reach, possibly

This Hawaii Volcano has erupted 33 times since 1843. Its most recent eruption was in 1984. The 1984 eruption lasted from March 25 to April 15. Before the eruption, increasing seismic activity could be felt on the island. During the eruption, many lava flows were produced, but fortunately, no lava reached the city of Hilo (“1984 Eruption”). There is a high likelihood that Mauna Loa will erupt again someday, so the volcano is closely monitored.

Because of all the uncontrolled eruptions that had happened in the past, a daily satellite and real time data from instruments around the volcano give scientists loads of information about the volcano.

This photo is of the Mount Pavlof, which is a volcano. This Mountain is located in the alaska peninsula wildlife refuge & the last time activity was recorded was on the date August 4, 2016. This Mountain is located about 625 miles southwest of Anchorage, Alaska.Mount Pavlof is a largely snow covered, cone shaped mountain with a high ridge extending to the southwest towards Little Pavlof. The mountain is about 7 km in diameter and has active vents on the north and east sides close to the summit. It is situated high on the northeastern flank of Emmons Lake caldera along a northeast-trending alignment of vents that includes Little Pavlof, Pavlof Sister, and several intra caldera cones.It’s one of the most active in the United States with eruptions

Seagulls flying in the sky on top of the golden sandy beach. Palm trees stand tall and strong. This is Hawaii, home to the great Mauna Loa. Mauna Loa is the largest volcano on earth. It is also one of the five volcanoes that created the beautiful island known as Hawaii. This shield volcano is one of the most active volcanoes in the world! The name Mauna Loa means “Long Mountain” in Hawaiian. Whenever this giant volcano erupts, it's usually extremely hazardous, threatening its surroundings. Mauna Loa may be very large and dangerous, but it is quite fascinating!

The active volcano that I chose to research is Popocatepetl volcano. Popocatepetl volcano is an active volcano located in Mexico. The volcano is oftentimes referred to as “El Popo” by many Mexicans. El Popo is a composite cone volcano. Being a composite cone volcano, El Popo is characterized by a steep cone shape, which was created by many composite layers of material pouring out over numerous eruptions. The lava that comes out of El Popo is extremely viscous. The highly viscous lava does not travel very far, and typically cools down rapidly. Scientists believe that El Popo is about 730,000 years old. It has erupted more than 15 times since 1519. In 1994 El Popo produced gas and ash, which caused nearby towns to evacuate. The toxic
