volcanoes occur there are different plate margins (Destructive and constructive) that will create different types of hazards. These hazards will include; lava flows, mudflows, pyroclastic flows, ash clouds etc. The majority of the hazards that occur are posed by physical reasons. The underlying reason that the hazards occur is due to the plate margins. The first type of plate margin is Constructive. Constructive plate margins will create a volcano due to the plates moving apart form each other. Due

high. It was first ascended in 1853. It is in the Cascade Range. Its first ascender was Thomas J. Dryer. Mount St Helens was caused by the subduction of the Juan de Fuca plate under the North American plate. The collision of these two plates is called a collision instead of a destructive because they are both continental plates. In 1980, a major eruption happened at Mount St. Helens. The eruption was the only significant one to occur in the 51 U.S. states since the 1915 eruption of Lassen Peak in

dictate by plate boundaries; they never appear at a transform boundary. They always appear on a divergent boundary where the two plates are pulling apart from each other, forming new crust. This creates a gentler volcano, as there is pure mantle forming the magma. They sometimes appear on a convergent boundary. When the two pieces of land are oceanic and oceanic, and oceanic and continental, volcanoes will appear. This is because you will get a subduction zone, where the denser plate will be forced

the country average is 240 people per km squared, and the megacities (Manila) population can go up to 2000 people per km squared. The Philippines is located in South East Asia and is North of Indonesia. It lies on a destructive plate boundary (Eurasian and Philippine plates) so as a result, there is regular volcanic eruptions which cause pyroclastic flows and lahars. As they’re vulnerable due to their lack of advanced infrastructure, this causes a disaster for them. An example of a volcanic eruption

Jackson Flattery Period 1 2nd Quarter Research Report January 10, 2017 1964 Alaskan Earthquake 139 people are believed to have died: 15 died as a result of the earthquake itself, 106 died from the subsequent tsunami in Alaska, 5 died from the tsunami in Oregon, and 13 died from the tsunami in California. An earthquake is, a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action. The 1964 Alaskan earthquake

It all began when Mount Saint Helen's erupted in May 18,1980 . The volcano has had Four big eruptions over the last 500 years .Mount Saint Helen's was named by a commander named George Vancouver and officers in 1792. In 1835 scientist recognized Mount Saint Helen's as a volcanoe.In 1857 through the 1980 Mount Saint Helen's was inactive .In May 18,1980 ,8:35am Mount Saint Helen's erupted.Causing deaths of 57 people .All the damages caused by Mount Saint Helen's was worth 1.1 billion dollars.The

Despite the extreme conditions that dominate hydrothermal vents on the East Pacific Rise and Mid Atlantic Ridge Bythograea thermydron, a eurythermal extremophile first described in 1980, lives in such high abundance that they are used as an indicator for active vent sites. Their approximate 4 year life span is spent at 2.7km below sea level at high pressure, a range of temperatures, low pH, low light intensity and sulphide levels toxic to most organisms. This essay covers the adaptations of B.thermydron

Mauna Loa is located in the island of Hawaii and is 4170 meters above the ground. Ever since 1832, Mauna Loa has shot out explosions of sultry lava 39 times and its last sudden eruption was in 1984. The USGS cerebrates the volcano has erupted about of once every 6 years over the past 3000 years. The Hawaiian Volcano Observatory celebrated the 30th anniversary of Mauna Loa's last eruption (in 1984) on March 25, 2014. Mauna Loa is the worlds most sizably voluminous mountain and volcano, it is a basaltic

Volcanoes and The Mauna Kea Volcanic Eruption By; Jonas Johnson 3rd Hour Imagine yourself sitting at home, and then a massive molten boulder suddenly smashes through your house, crushing everything, including you. This is what some victims of natural disasters have to go through. A natural disaster is any natural occurrences that usually cause great amounts of damage. The most common of which are volcanoes, hurricanes, tornadoes, earthquakes, and tsunamis. The Mauna Kea Volcano is an ancient dormant

The Nevado del Ruiz is a volcano in Colombia. The volcano is located in the Andes volcanic chain on the andean volcanic belt. Nevado del Ruiz was formed by subduction on the nazca oceanic plate boundaries. Subduction is “a geologic process in which one edge of one crustal plate is forced below the edge of another.” The Nevado del Ruiz is known as an active stratovolcano. ”A stratovolcano is a tall, conical volcano composed of one layer of hardened lava, tephra, and volcanic ash.” Stratovolcanoes
