environment. Therefore‚ in this case a volcanic hazard is the threat posed from natural volcanic processes towards the populations and the environment. The extent of volcanic hazards can vary due to two factors; physical factors such as the type of volcano and human factors such as the population density in the area. Volcanic hazards can also be placed into two phases: primary hazards such as lava flows and gas emissions; there are also secondary hazards such as lahars and landslides. The management

to draw conclusions on what could be done to mitigate loss of life and destruction. The eruption of Mount Vesuvius in 79 AD on Pompeii and surrounding areas proved to be catastrophic because of the location of the volcano and especially since citizens were not aware that an active volcano was in their midst. By examining the series of events that took place at Mount Vesuvius in 79 AD and comparing them to the impacts and forecasting of present day volcanism‚ one could draw better conclusions of the

Volcanoes are big erupting mounting that shoot out hot lava/magma. Volcano eruptions produce a lot of toxic gases which can damage the environment. When a volcano is about to erupt there is rain‚ thunder‚ and lightning. Volcanoes can also be bigger or smaller than a mountain. There are many different types of volcanoes that cause destruction throughout the entire world. Volcanoes occur all over the world anytime of the day. Volcanoes occur at the mid-ocean ridges because they are divergent plate

worry about hazards of eruptions of super volcanoes. “The term "super volcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI)‚ meaning the measured deposits for that eruption is greater than 1‚000 cubic kilometers (240 cubic miles)”. (Questions About Super volcanos‚ 2015). According to the definition of super volcano‚ we know that super volcano is actually a kind of volcano‚ which erupt more than one thousand cubic kilometers of deposits. Within

The Smithsonian Global Volcanism Program defines an active volcano as having erupted within the last 10‚000 years. A volcano finally goes extinct when there’s no lava supply in the magma chamber beneath the volcano. There are approximately 1‚500 active volcanoes in the world today and 75 percent of them are located in the Pacific Ring of Fire. On average‚ 50-70 volcanoes erupt every year. Nyamuragira – D.R. Congo -Africa’s most active volcano‚ Mount Nyiragongo is located in Virunga National Park in

As the bell of the bank rang‚ Volcano Man flew over to stop the robber. Volcano Man had bright flames as hair. He was a known force in the city because his superpowers were acknowledged by everyone. Volcano Man could fly and send balls of lava to an enemy. Of course‚ hw wouldn’t shoot at a normal mortal because it would fatally wound them. Instead‚ he shoots ball of lava from a distance‚ so that the lava can cool and not kill his target. At the bank‚ Volcano man scanned the premises for a trooper

The volcano that possibly killed a majority of the human species and the volcano that currently resides in Yellowstone are both a special kind of volcano called a super volcano‚ which you will

we must define a hazard. A hazard is a situation that poses a level of threat to life‚ health‚ property or environment in this case caused by a volcano. I will now analyse how the factors affect the hazards. One factor that must be considered is the viscosity of the magma. The viscosity can determine how violent the eruption is and what shape the volcano becomes. Viscosity can be affected by temperature‚ dissolved gases in the magma and its silica content. High temperatures can make the magma less

a super volcano. Super Volcanoes: Super volcano? that sounds a bit fictional. But there is such thing. A super volcano refers to a volcano that produces the largest and most voluminous eruptions on earth. The explosivity of these eruptions vary‚ yet the sheer volume of magma that will be emitted is great enough to radically alter the landscape and severely impact global climate for years‚ with a catastrophic effect on life. What makes a super volcano different to a normal volcano? A super

Katla‚ is a sub-glacial volcano. The caldera of the Katla volcano has a diameter of 10 km (6.2 mi) and is covered with 200–700 meters (660–2‚300 ft) of ice. The peak is about 1512 m / 4‚961 ft high. Twenty eruptions have occurred between 930 and 1918‚ at intervals of 13–95 years or by some estimates 40- 80 years.The last eruption was in1918. Katla has not erupted for ninety-nine years. However‚ since May 2012‚ the large volcano has become restless. Today‚ November 29‚ 2016 a
