Disadvantages: Sea - during a volcanic eruption earthquakes happen‚ and tsunamis may be created. Also‚ if it is a volcanic island‚ the island may be destroyed‚ and there is no escape. Lava flow - these are very slow moving‚ but destructive as they cannot be stopped and they set fire to everything in their path. Pyroclastic flow - these are impossible to outrun‚ travelling at about 300 km/h‚ and are extremely destructive Mudflow/lahar - these are mud rivers that have the consistency of cement

A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods‚ volcanic eruptions‚ earthquakes‚ tsunamis‚ and other geologic processes. A natural disaster can cause loss of life or property damage‚ and typically leaves some economic damage in its wake‚ the severity of which depends on the affected population’s resilience‚ or ability to recover.[1] An adverse event will not rise to the level of a disaster if it occurs in an area without vulnerable

The Components Of Earth’s Atmosphere And How Our Climate Is Affected By Volcanic Eruptions Introduction The atmosphere is all that lies between us‚ and the vast and unforgiving conditions of space. It absorbs energy from the sun‚ protects us from radiation‚ supports the cycle of water and other chemicals‚ and interacts with Earth’s magnetic fields to give us a climate capable of supporting life. Without it there would be no water‚ no air‚ no life. So we must protect it. But to protect

A volcano is an opening‚ or rupture‚ in the surface or crust of the Earth or a planetary mass object‚ which allows hot lava‚ volcanic ash and gases to escape from the magma chamber below the surface. On Earth‚ volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge‚ for example the Mid-Atlantic Ridge‚ has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic

Volcanic Eruptions: 79 AD Versus the Present ATOC 250: Natural Disasters Term Paper Abstract: Volcanic eruptions can be disastrous and deadly. It is‚ therefore‚ important to look back at prior eruptions and compare them to present eruptions in order 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

(crust) is divided into tectonic plates which are constantly in motion due to the convection currents caused by heat cycles in the mantle‚ driven by radioactive decay in the Earth’s core. Natural hazards caused by plate tectonics are earthquakes‚ volcanic eruptions (and tsunamis – secondary effect of the first two). It is important to understand that there is a clear division between a natural hazard and a natural disaster. A good example would be the 1906 San Francisco earthquake which killed about

Illustration by Mark Garlick‚ Science Source Ker Than for National Geographic News Published February 12‚ 2013 New insights about the asteroid thought to have killed off the dinosaurs suggest it may have just been the final blow‚ and that the reptiles were already suffering from a finicky climate prompted by volcanic eruptions long before

Creation of Oahu by Volcanism Karen Ta: 430 BOT 450 TR 10:30-11:20 Volcanoes are magnificent formations from an opening in a planet’s crust. They form when magma‚ volcanic ash‚ and gases escape from a magma chamber below the surface of the planet. Tectonic plates cover the surface of the planet and are constantly moving. Volcanoes are generally found where these plates converge or diverge. Not only are volcanoes found in these areas but also where the Earth’s crust is stretching or thinning
