Types of Volcano Erruption

Vol scum bagic eruptions have caused round of the worst disasters in the world. They rouse wipe out entire cities and vote flock thousands of people. The name of volcano comes from Roman term. It derives from Vulcan which is the name of Roman fire god. Romans believed that Vulcan lived on a volcanic Italian coast. Romans called the island Vulcano. According to scientists, volcanic eruptions be sh ard in to four basic groups. They are commonly known as Hawaiian, Strombolian, Vulcanian, and Peleean. The term of Hawaiian eruptions are named after the volcanoes in Hawaii. These volcanic eruptions are the least violent type.They produce highly fluid lava which flows quietly. This gradually builds up a shield volcano. Strombolian eruptions are named after Stromboli. These result from the constant run down of gas from the magma. As the gas escapes, it produces tephra that piles up, turning into a clinker brick cone. Strombolian eruptions happen when sticky magma plugs the central ve nt. This makes the magmatic gas build up insistence until it blasts. The magma is turned into volcanic dust and bombs. Vulcanian eruption which comes from the ancient Roman belief, are more violent than the strombolian eruption.Vulcanian eruption happens and brings magma which is more viscous. Vulcanian explosions are usually bigger and noisier than the Strombolian eruptions. Paleean eruptions are famous as the nigh violent kind of volcanic eruptions. The name of Paleean comes from the eruption of Mount Pelee, Martinique in 1902. It killed almost 38 thousands people. A Peleean eruption occurs when the magmatic gas build up tremendous pressure. This causes violent explosions with earnest clouds of hot ash and dust. Tornadoes are known as one of the most damaging disasters.A tornado is a very powerful column of winds which spirals nearly a center of low atmospheric pressure. A tornado lead look like a large black funnel which hangs down from a storm cloud. The name tornado derive s from the Latin tonare. It means to thunder. epoch the Spanish developed the word into tornear which means to turn or pulling. T his is why a tornado is sometimes called twister or cyclone. The winds inside a twister can spin around at speeds up to 500 miles an hour, but it usually get goings at roughly three hundred miles an hour.This speed twisting makes a tornado the most dangerous storm. The number tornado has a diameter of about 200 to 300 yards. The small tornadoes are known as satellite tornadoes. These small offspring, about 50 yards acro ss, can be very fierce and do lots of damage. The phase angleing of a tornado can be very quick. Sometimes it can form in a minute or less. A tornado can travel across the ground at high speeds, then it can sudden ly vanish. Most tornadoes last less than twenty minutes and travel less than 15 miles. However, the super storms sometimes travel over nose candy miles before they are exhausted.
