Volcanology

Mount St. Helens is a volcanic stratovolcano still actively located in the Cascade Range in Western North America in the state of Washington. It was formed by a subduction plate boundary also located on the Juan de Fuca plate. The Cascade range is one of the most famous mountain ranges, and has one of the most active volcanos located in Western North America. Other areas or famous landmarks surrounding Mount St. Helens are the South Fork Toutle River, North Fork Toutle River, Castel lake,…

The moai statues lie on an island in Chile, commonly known as Easter island or Rapu Nui to its earlier people. The island is 64 square miles, and located 2,500 miles from Tahiti and 2.300 miles from Chile. Each statue ranges from 12 to 14 feet tall, and weighs approximately a ton. Although no written history lies on the land, historians believe the statues represented important people such as ancestors, chiefs or worshipped deity’s. The people of the island were sea farers who most likely…

Volcanoes There are many volcanoes in the world, in all shapes and sizes. Some volcanoes are created by other volcanic eruptions such as the Cinder Cone volcano. I am going to inform you about the Cinder Cone volcano, Shield volcano and the Composite volcano. Cinder Cone volcanoes are the smallest volcano in the world and are named after their shape. Cinder cone Volcanoes, also known as the Scoria Cone, is the most simplest volcano. They are less than 300 meters high, making them the…

Teesdale is revered as one of the most beautiful and spectacular areas in England. Its peaceful, unspoilt landscape is richly endowed with natural beauty and provides an incredible feeling of solitude and tranquillity. In 1988 the whole of Upper Teesdale was included in the designation for the North Pennines Area of Outstanding Natural Beauty (AONB). It stretches across 772 square miles (2000km²) and takes in parts of County Durham, Cumbria and Northumbria. The area is well-known for its…

The Mount Vesuvius Volcano has erupted many times. Since AD 79, the volcano has also erupted repeatedly, in 172, 203, 222, 303, 379, 472, 512, 536, 685, 787, around 860, around 900, 968, 991, 999, 1006, 1037, 1049, around 1073, 1139, 1150, and there may have been eruptions in 1270, 1347, and 1500. The volcano erupted again in 1631, six times in the 18th century (especially in 1779 and 1794), eight times in the 19th century (notably in 1872), and in 1906, 1929 and 1944. In this assignment I am…

In this set of materials, the reading passage tells us about the three types of rock, and the listening passage explains the additional usage of sedimentary rock, which is describing as a third rock in the reading passage. The reading passage informs us about the characteristics of the three rocks. The most common rock is Igneous rock which means fire. The example of it is granite. By cooling and solidification of lava, igneous rock will be formed, and this makes up approximately 64.7% of the…

Mt. St. Helens is a stratovolcano part of a group of volcanoes called The Ring of Fire. These are created from the convergence/subduction between the Juan De Fuca plate and the North American plates. Its most common type of eruption is intermediate eruptions, which is what the composition was in its most recent eruption. Mt. St. Helens most recently erupted on May 18, 1980. An earthquake right under the mountain caused an enormous landslide/avalanche going close to 150 mph. A huge hazard from…

Believe it or not volcanos from the past are good for today. So back in the day when volcanos erupted they would deposit rock and minerals into the ground where farmers would have their crops. So today after so many years the soil where the farmers planted their crops is so rich from the deposit of rocks and minerals into the soil. For example when you have rich soil that means two thing that your crops are going to be good. Then the last thing that is that your pastures are going to be good…

This week I learned about the three different types of volcanoes and the types of volcanic hazards associated with each type of volcano. This information is important to me because now I understand the hazards associated with living in certain parts of the country that have volcanoes. I understand that the volcanoes found in Hawaii (Shield volcanoes) erupt differently and pose different dangers than the volcanoes in the Cascade Mountain Range (Composite volcanoes). Since I live in Portland,…

Erta- Ale, is today the longest continually erupting volcano on the planet. It is pretty much a lake of lava that has been molten for over 100 years. These same volcanic forces are what created Ethiopia’s highlands. Seventy million years ago, Ethiopia’s land was just flat and deep terrestrial land. It wasn’t until molten lava rose from the Earth’s core and crated a huge dome of rock 500 miles wide: the roof of Africa. The summit is about three miles high and are home to some very…
