the volcano sits far below the ocean’s surface‚ even a major eruption may not be detected from above. Nonetheless‚ care must be taken when exploring areas surrounding a submarine volcano. Since 1650‚ when the Kolumbo submarine volcano erupted‚ killing at least 70 people on the nearby Greek island of Santorini‚ submerged volcanoes have been known to be deadly. Submarine volcanoes‚ as the name suggests‚ are volcanoes that sit under water on the ocean floor. The biggest underwater volcano is

some volcanoes more hazardous than others? There are several reasons that influence volcanic hazards‚ these include the viscosity of the magma‚ proximity to population centres‚ materials that are ejected from the volcano‚ the magnitude of the eruption and the plate margin that the volcano rests upon. The viscosity of the magma depends on 3 things‚ the temperature‚ dissolved gasses and the chemistry involved in the magma. These factors produce 2 main types of magma called acid and basic. The acid

or environment‚ a volcano can compromise all these things through the many hazards volcanoes presents. Such as lahars‚ flash flooding‚ landslides‚ pyroclastic flows‚ ash clouds and many others. There are factors which can influence the severity of the hazard and cause differences in them and can be classified into different categories‚ such as physical‚ economic‚ political and social. One physical factor which causes differences in a volcanic hazard is the steepness of the volcano. If the volcanoes

People can distinguish these calamities to excogitate different methods to prevent natural disaster like tsunami and volcano eruption. By using those methods‚ people can keep away from disaster safely. Here are two specific scientific and technological can be forecasted achievable are going to discuss hereinafter. What I’m

meters‚ it is Europe ’s highest active volcano. The height of its summit changes with each eruption‚ and over the centuries a few lava flows have reached the coast. Over 1200 square meters of Etna ’s surface is covered with solidified lava. Etna offers skiing in the Winter months and breathtaking hikes in the woods during the Summer. There are also a number of smaller peaks on the slopes of Etna‚ and some interesting caverns. Since Etna is a strato volcano‚ with relatively cool lava temperatures

composite volcano can be referred to as a cone volcano. These volcanoes have tall narrow cone and a wide base. Their magma chambers contain thick acidic lava‚ which means sometimes you can walk faster than the lava when it is moving! The layers of a cone volcano are usually alternated between lava and ash. A shield volcano usually has a wide cone and gentle slopes. The lava that is ejected during an eruption is thin due to it being basic (alkali). At first thought‚ you would think a volcano to be

volcano A volcano is an opening‚ or rupture‚ in the surface or crust of the Earth or a planetary mass object‚ which allows hot lava‚ volcanic ash and gases to escape from the magma chamberbelow the surface. On Earth‚ volcanoes are generally found where tectonic plates are diverging or converging. Amid-oceanic ridge‚ for example the Mid-Atlantic Ridge‚ has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent

The tallest volcano on Earth is Mauna Kea‚ one of the 5 volcanos that make up the Big Island of Hawaii. The summit of Mauna Kea is 4‚205 meters above sea level‚ but its true height is much larger. When measured from the sea floor‚ Mauna kea is more than 9‚000 meters tall‚ making it the tallest mountain on Earth.The tallest volcano on Earth is Mauna Kea‚ one of the 5 volcanos that make up the Big Island of Hawaii.

Three types of volcanoes are the shield volcano‚ Strato Volcano’s and cinder cones .The Shield volcanos are usually built entirely from lava flow they are name for their large size and low profile. The Starto’s volcano’s have steep sides with cones that stick out like huge bumps. They are built up when eruptions of viscous lava‚ tephra‚ and pyroclastic flows happen. The Cinder cones is a steep conical hill of tephra that accumulate
