The nature of a volcanic eruption differs depending on the type of volcano, lava and eruption; this will also affect the hazards posed by volcanic eruption. Many substances can be erupted when volcanoes erupt including co2 gases, ash, pyroclastic flows and lava. Different substances that are spewed from the volcano create different hazards. In the Chaiten eruption in Chile, a plume of ash rose into the air and spread across to Chile and neighbouring country, Argentina. The ash created both environmental

Analysis and Impact of the Geologic Features In Iceland By: Tan Kai De Introduction Iceland is an island located in the middle of the North Atlantic and Arctic Ocean, and with a population of just over 300,000, it is the most sparsely populated country in Europe, with its people inhabiting a total land area of 103,000 square kilometers. To put that into perspective, the Netherlands is about two and a half times the area (nationsonline.org, 2015), but has nearly 60 times the population at nearly

One of the most powerful volcano was Mount Tambora. It is one of the largest eruptions that went down in history. This eruption happen on April 10, 1815, this eruption was so powerful that it killed around 100,000 people. Mount Tambora eruption was a 100 times more powerful than Vesuvius. “Mount Tambora is a stratovolcano, also known as a composite volcano.” (Smarter, 2016). In addition to a stratovolcano conical form, other familiar characteristic include the volcano’s vertical profile, thick

But upon closer examination, it turned out to be an actual human. The liquid was sizzling, but there was the outline of a man. I saw three more in the hallway, and more in the streets. I was fear stricken. The giant ash that had come out of the volcano in the first weeks or so how transformed them into mummies. The ground was rumbling. I then got out of my day dream, and ran through the city outskirts. Going over a mountain pass as the other roads had been destroyed. I hope

Introduction Volcanic eruptions are historic geographical events with a wide scope of study. A volcano is created when magma, rock fragments, gases and ashes erupts from the earth’s interior onto the surface. There are different forms of volcanoes depending on the chemical composition and condition of magma erupted. Magma is referred to as lava once it is erupted onto the earth surface. A volcano is termed as “active” when it is in the process of eruption and “dormant” when there are no signs

so there was more land being submerged under water. The eruption of volcanoes in Hawaii is what influences an Earthquake. According to scientist Earthquakes are common after a volcano has erupted. The Hawaii was formed by a convergent margin of oceanic lithosphere plates. These plates join and on occasion can create a volcano. They can also be made in the middle of the plate where there is magma. If the magma erupts and hit the sea floor that is called a hot spot. A hot spot in the center of the Pacific

ashes What can supply chain executives learn from the Iceland volcano? In late March, reports of minor volcanic eruptions in Iceland were buried in the news. Talk was limited to thrill-seekers getting too close and the impact of flooding on farmland in the immediate vicinity. After all, how could a volcano in Iceland impact countries thousands of miles away? That all changed when a major eruption of the Eyjafjallajokull volcano sent a stream of ash into the sky, shutting down British airspace

that have swept over hundreds of square miles, emitted noxious gases that have caused lung ailments and produced ash clouds that have brought down passenger jets and blanketed thousands of square miles. Mount St. Helens and Mount Rainier are active volcanos, their domes has been visibly growing for a number of years. Both St. Helens and Rainier have been produced spurts of increased seismic activity in the last couple of months. Japan is a series of volcanic islands with 10% of the world’s active

Field Trip Project G148C Lava Beds National Monument For my class field trip I visited Lava Beds National Monument. This beautiful monument is home to the Medicine Lake Shield Volcano. Medicine Lake is the largest volcano by volume in the Cascade Range. Over the last half-million years, volcanic eruptions from this volcano have created a rugged landscape of volcanic features. It is home to over 700 caves, native american rock art sites and battlefields. It is an oasis in the high desert wilderness
