On September 27, 2014 Japan’s Mount Ontake erupted catching everyone by surprise, including over 250 hikers at the resorts and shrines on the peak. In contrast recently everyone around the globe was able to track the eruption by Iceland’s Bardarbunga due to a web of advanced technology, allowing them to even track where the magma was underground. Japan has a very similar array but was unable to predict Ontake’s eruption. This is due to the fact that it was what is called a phreatic eruption, or…

They both relate because they both occur when tectonic plates move. When a volcano is in their active stage of life it will experience seismic anomalies being caused by the movement of magma within the chamber, then when the rocks are really hot and earthquake will arise. Earthquakes and Volcanoes occur when tectonic plates are moving. Tectonic plates are pieces of the earths crust and upper mantle. Earthquakes are cause when the rock underneath us suddenly breaks along a fault. The release of…

Mount Fuji is a volcanic mountain situated in Japan, south-west of Tokyo on the largest island, Honshu. It’s longitude is 35.3606° and its latitude is 138.7278°. It is over 3.7 kilometers tall, making it the highest volcano in Japan. The last confirmed eruption of Mount Fuji, was on the 15th of December 1707. It is still an active volcano. In 2014 there was speculation that it would erupt because of the pressure from the 2011 earthquake which reached 9.0 on the Richter scale. Mount Fuji was not…

Mount Saint Helens On the day of May 18, 1980 at 8:32 a.m., one of the most deadly and economically destructive volcanic eruption took place. This eruption was from Mount Saint Helens located almost one hundred miles south of Seattle, Washington. The famous eruption killed fifty-seven people, destroyed two hundred fifty homes, forty-seven bridges, fifteen miles of railways and one hundred eighty-five miles of highway. Mount Saint Helens had been dormant for the past one hundred twenty-three…

gases explode and may burst out the sides of the cone in addition to the summit crater. Mt Vesuvius is a Stratovolcano also known as a composite volcano. Stratovolcanoes are also called composite as they are made of built up of alternating layers of lava flow, ash and blocks of unmelted stone. Stratovolcanoes form above the subduction zone at plate boundaries. They are known for erupting with great violence. They are larger than cinder cones nd result from a conduit system; vents lead from…

Mazama's first eruption was somewhere around 420,000 years ago,” says UMASS (the University of Massachusetts). As hundreds of thousands of years passed, Mazama’s eruptions became more violent and destructive. These eruptions usually included thick lava and slow flows. USGS informs us. “These eruptions, however, were nothing compared to Mount Mazama’s major eruption years after.”…

A giant is born from the depths of the ocean, a catastrophe waiting to happen. As hot magma bubbles up from the depths of the earth, it pushes through the surface and Krakatoa is born. The 1883 eruption of Krakatoa was devastating. The resulting toxic gases, deadly pyroclastic flows, and giant tsunamis are astonishing. The eruption of Krakatoa was the loudest eruption ever heard in history. Krakatoa is located in the Sunda Strait between Java and Sumatra in Indonesia. The island of Krakatoa is…

Volcanoes exist all around the world. A volcano is a break in the Earth’s crust that produces lava, gases, ash. Some volcanoes are active and some volcanoes extinct and dormant. Magma usually forms 30 to 120 miles beneath Earth’s surface. Most volcanoes are tourist attractions and most people like to climb them and to live near them to produce some heat to there house when the people don't have any heat. Villarrica is located in the country of chile. Villarrica has a 4 star warning and…

Kilimanjaro rises approximately 4,877 metres (16,001 ft) from its southern base in the plains near the municipality of Moshi to its summit height of 5,895 metres (19,341 ft).[2] Kilimanjaro is the highest volcano outside South America.[7] Kilimanjaro is a large stratovolcano and is composed of three distinct volcanic cones: Kibo, the highest; Mawenzi at 5,149 metres (16,893 ft);[8] and Shira, the shortest at 4,005 metres (13,140 ft).[9] Mawenzi and Shira are extinct, while Kibo is dormant and…

volcanoes formed in what known as the Ring of Fire. The first volcano being investigated is Augustine which is better known as a stratovolcano; they are unique because they are shaped the type found all around the Ring of Fire. Over the years solidified lava flows gradually built up around the…
