magma to rise and come out together with gas‚ rocks and ashes. Violence of an eruption depends on how much pressure the volcano is under before it erupts. (How do volcano erupt) “In a volcanic eruption‚ hot lava spews out from beneath the Earth’s crust up to the Earth’s surface.” The hot lava spewed out is actually magma‚ hot melted rock. (Why do volcanoes erupt) “Sometimes the magma chamber breaks its sides and only reaches to the flank or summit of volcano and sometimes reaches to the surface causing

A hazard is a situation that poses a level of threat to life‚ health‚ property‚ or environment. There is a very big difference that helps prepare for a volcanic hazard and that is whether you are in a MEDC or a LEDC. In a MEDC monitoring volcanic zones and potential hazards is an option many LEDC’s don’t have. In Italy at Mt Etna they have Geochemical monitoring programs currently run by INGV which focus on the analysis of temporal changes‚ chemical changes and seismic activity. This option open

In the autobiography‚ Geryon is particularly interested in the story of Lava Man‚ who defies death by surviving a volcanic eruption. He is described by Herakles grandmother: “I am a drop of gold he would say I am molten matter returned from the core of earth to tell you interior things- Look! He would prick his thumb and press

CINDER CONE VOLCANO The cinder cone volcano‚ commonly found in volcanic areas‚ are constructed of rocks and ashes. Gas created from the lava is blown into the air which then “cools and solidifies as small rocks or cinders”. Cinder cone eruptions “take place in basaltic volcanic fields” that immensely effect the human population surrounded by it. Cinder cone eruptions majorly impact the environment by distributing volcanic gases‚ volcanic landslides and blasting tephra. One of the long-term impacts

So he then walked out of his cave in Mount Olympus. He then saw ash and lava surrounding one of Kina’s creatures‚ cricket. Balboa thought Hephaestus must have taken Kina. He walks in a slow pace back and forth wondering why Hephaestus would want Kina and then remembered that he and Zeus had banished his son Magum for destroying

Mount Kilauea is the youngest volcano in Hawaii. It has a lava level of 740 ft. under the rim. “Kilauea was formed under a hot spot under the crust. So were the other volcanoes on the Big Island such as Kohala‚ Mauna Kea‚ Mauna Loa‚ and Hualalai. There have been 34 eruptions since 1952 and 61 eruptions total”

ENDOGENETIC PROCESS: The Endogenetic processes are the processes that shape the land by forces coming from within the earth (Endogenetic forces). There are 3 main Endogenetic processes: folding‚ faulting and volcanism. They take place mainly along the plate boundaries‚ which are the zones that lay on the edges of plates. These zones are weak. Endogenetic processes cause many major landform features. MOVEMENTS: The forces coming from within the earth cause two types of movements in the earth.

properties of air allow for larger eruptions than those that occur underwater (Mitchell 444). Pressure on the ocean floor does not allow water or gasses to escape from lava. This causes the eruption to have less of an impact underwater than it would if it were on land. Water’s ability to hold heat aids in cooling the erupting lava quicker than it would when exposed to the air (Mitchell 444). This article is important in order to further research by geologists and oceanographers‚ making this an interdisciplinary

Socially the town of Zafferana Etnea was threatened by the largest volume of lava in hundreds of years‚ this can also be seen as an economic impact. In 2002 a huge column of ash was thrown up from the biggest eruption in recent years and was deposited as far away as Libya. Seismic activity associated with these eruptions caused the eastern flanks of the volcano to slip by 2m‚ causing structural damage to many houses. Lava flows completely destroyed the tourist station at piano Provenzana and part
