by a volcanic eruption. The mudflows and the flow of debris from these are often one of the deadliest volcano hazards. This is the flow of mud‚ rock and water that rush down valley and stream channels reaching speeds of up to 40 mph and can travel more than 50 miles. These mudflows look like fast-moving rivers of wet concrete. These can occur during a volcano’s eruption or when the volcano is quiet. The water creating the flow occurs from melting snow and ice or intense rainfall. Glacier-clad

Living near Hawaii’s volcano‚ Kilauea‚ is not worth the risk because of the uncertainty of the volcano erupting once again. In the article‚ “A force of nature‚” there are many dangers that can occur. The gasses emitted from the volcano is toxic‚ these toxic gasses could affect people’s health in major ways. One way that people’s health can get affected by the volcano is‚ when the gases are released into the air‚ the gases in the air can be inhaled. These gases can harm a human body in major ways

Cause and Effect A volcano erupts when magma escapes from inside the earth. As the magma is escaping from a confined space‚ a lot of energy is released with it‚ as happens with any other explosion. This is why many eruptions also produce huge quantities of gases and dust. Magma sometimes rises under enormous pressure‚ so it not only finds cracks in the earth’s crust‚ it can also create them. When magma reaches the earth’s surface it is called lava. An eruption is caused by lava escaping

structure of the shield volcano is large and consists of a lava chamber and a plug‚ which will cause a great explosion if blown. The sides are made of layered tephra (rock fragments and particles) and dried lava. Strato Volcano’s have a thicker lava similar to putting a cap on a soda bottle and shaking it up. When the pressure becomes too immense‚ the plug releases and causes a heavy eruption which includes a pyroclastic flow. When the emitted Lava collects on the sides of the volcano it backs up and forms

Krakatau Krakatau (Krakatoa)‚ is said to have created the worst volcanic eruptions in history‚ in 1883. Ancient Krakatoa formed in 416 A.D. and still exists today in Indonesia. That same explosion‚ in 1883‚ created 130 feet tsunamis‚ which destroyed 130 coastal homes‚ two docks (India and Australia)‚ and killed about 36‚000 people. It created very loud sounds and was heard as far away as Madasagascar‚ about 3‚000 miles away from Java‚ where Krakatau was. Some people even believe that it may

Olympus Mons‚ one of the many volcanos found on Mars‚ is a giant shield volcano ("Mars | Volcano World | Oregon State University"‚ 2016). To give the phrase "giant sheild volcano" scale‚ Olympus Mons is 374 miles in diameter‚ meaning the extraterrestrial volcano is roughly the size of the state of Arizona ("United States

First‚ we will discuss Mount St. Helens Volcano. Mount St. Helens is a stratovolcano located in the Pacific Northwest of the United States within Washington State. A stratovolcano is also known as a composite cone‚ which is “a large symmetrical structure that consists of alternating layers of explosively erupted cinders and ash interspersed with lava flows (Lutgens‚ 2012.)” Due to the cone shape of the volcano‚ stratovolcanoes are known for creating large explosive eruptions that can eject vast amounts

Do you know what the biggest active volcano in the world is? Mauna Loa is so big in volume and so heavy that it causes the Pacific Plate that it sits on to sag under its weight! Although Mauna Loa has not erupted as many times as its sister‚ Kilauea‚ it has caused more damage with every earthquake and explosion it has had. The elevation of Mauna Loa is 13‚678 ft and its height from the ocean floor is 30‚080 ft. Mauna Loa is a shield volcano‚ but it can develop into a cinder cone. It has had
