Volcanos are mighty mountains that rise from the ground but these beautiful beast come with a catch. When they “wake up” they can tear a whole island or town to pieces and pieces. Most volcanoes cause tons of destruction including flames and lava when awakened this roaring beast isn’t so peaceful. When volcanos form they form just like a regular mountains actually they are they are just regular mountains.That is why when they erupt it shocks many people because they all thought the possibility

With reference to two volcanic events that you have studied from contrasting areas of the world‚ compare the nature of the volcanic hazard and its impact. Mount St Helens erupted on the 18th May 1980 at 9am and is an active strata volcano Washington State USA‚ a MEDC. Where as on 18th July 1995‚ during the daytime‚ Montserrat‚ a LEDC during the day‚ Montserrat’s Soufrière Hills composite volcano of a height 1050m‚ meaning sulphur hills‚ dormant for centuries‚ erupted and produced a phreatic eruption

A stratovolcano is also known as a composite volcano. It is built up by many layers called strato‚ lava‚ tephra‚ pumice and volcanic ash that has become hardened. Stratovolcanoes have a steep profile and they have many explosive eruptions that cause craters that have collapsed called calderas. The lava flow from a stratovolcano normally cools before it has the chance to spread. This is due to the viscosity of the lava being extremely high. One of the most famous stratovolcanoes is Mount Vesuvius

Energy Source of Natural Hazards Disasters occur where and when the earth’s natural processes concentrate energy and then release it‚ killing and causing destruction. Four energy sources make the earth an active body: 1) the Earth’s internal energy; 2) solar energy; 3)gravity; 4)the impact of extraterrestrial bodies The interior of the Earth holds a tremendous store of heat released primarily from the ongoing decay of radioactive elements. Earth’s internal energy flows unceasingly toward the

When people hear of Santorini‚ they think of the islands in Greece located in the beautiful waters of the Aegean sea. What many people do not know is that Santorini is in fact a scope of volcanoes‚ also known as shield volcanoes. Shield volcanoes are easily identifiable because they actually look like volcanoes (“Shield Volcanoes‚” 2016). I have actually had the pleasure of visiting Santorini a few years ago and I have included some pictures. Some of the things I have learned about this volcanic

At the base of Mount Fuji‚ Aokigahara is located‚ is it believed to be the most infamous forest in all Japan. This is also known as the Sea of Trees(Jukai)‚ Suicide Forest and Japan’s Demon Forest. This forest has over 500 confirmed suicides since the 1950s (TOFUGU). Aokigahara is a forest that spreads across the northwest base of Mount Fuji‚ it is less than 100 miles from the west of Tokyo. This forest is growing on top a lava that flowed during the eruption of Mt. Fuji in 864. The forest has been

Igneous rock is a Latin word meaning fire; these rocks are formed from volcanic activity. This rock is one of three types of rock including sedimentary and metamorphic rock. Igneous rock is formed from the cooling and solidification of lava or magma. Igneous rock can be formed with our without crystallization‚ below the surface as intrusive rocks or on the surface as extrusive rocks. Volcanic rocks also known as extrusive igneous rocks include all the products resulting from volcanic eruptions of
Premium Igneous rock Basalt Volcanology
Magma Chamber – A magma chamber is a large underground pool of molten rock sitting underneath the Earth’s crust. This magma is less dense than the surrounding mantle and so it seeps up to the surface through cracks and flaws in the crust. When it reaches the surface‚ it results in a volcanic eruption. Lava – Lava is the rock expelled from a volcano during an eruption. When it first comes out‚ the lava can have a temperature higher than 700 degrees C. It then flows downhill from the eruption point

The two volcanoes from these events are called stratovolcanos‚ meaning they are volcanoes built up of alternate layers of lava and ash(citation)‚ and cone shaped. Neither of these volcanoes are shield volcanoes‚ which are broad‚ domed volcanoes with gently sloping sides‚ characteristic of the eruption of fluid‚ basaltic lava(citation). Both of these volcano’s had a huge impacts on humans‚ human structures and property‚ and had very high damage costs. The major Mount St. Helens eruption was on

The Grand Canyon was once a part of a continental collision about 1.7 billion years ago when volcanic islands collided in the south west of America‚ where the North American plate is now. Mountain building occurred about 75 million years ago when the uplift of almost 2 miles in the region‚ (called a Laramide orogeny event) started and created the Colorado Plateau. The rocks in the Grand Canyon were igneous or sedimentary rocks before the collision of tectonic plates. The collision pushed the plates
