Introduction Various disasters like earthquake‚ landslides‚ volcanic eruptions‚ fires‚ flood and cyclones are natural hazards that kill thousands of people and destroy billions of dollars of habitat and property each year. The rapid growth of the world’s population and its increased concentration often in hazardous environment has escalated both the frequency and severity of natural disasters. With the tropical climate and unstable land forms‚ coupled with deforestation‚ unplanned growth proliferation

Nuclear Energy 1. What is nuclear energy? Text Book Pg 80 2. Nuclear Fission :- In nuclear physics and nuclear chemistry‚ nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei)‚ often producing free neutrons and photons (in the form of gamma rays)‚ and releasing a tremendous amount of energy. The two nuclei produced are most often of comparable size‚ typically with a mass ratio around 3:2 for common fissile isotopes.[1][2].The smallest

Nuclear energy – Uses and abuses Nuclear energy is the energy created from the nucleus of atoms. The nuclear power is released in nuclear reactions which can be nuclear fusion and nuclear fission. In nuclear fusion‚ atoms combine together to form a larger atom. This is accompanied by the release or absorption of energy. Large scale fusion processes involve very high temperatures and densities‚ such as the production of energy from the sun and the shine from stars we see in the night sky. On the

At this time in our world we live in I do believe nuclear terrorism is a huge threat and the U.S. should be very concerned about it. It was noted by Jeffrey T. Richelson that “declassified documents have confirmed that the U.S. (and other) governments have anticipated the possibility of a terrorist nuclear incident at such high-profile events as the 2009 inauguration of President Barack Obama and the 2010 Vancouver Olympics” (Richelson 2012). United States government officials have been concerned

Nuclear power is one of the most controversial energy sources in Canada and also throughout the world and is being talked about very frequently lately as to whether or not it is a safe alternative to other forms of energy such as coal or oil. In my opinion‚ energy from uranium (nuclear power) is a reasonable alternative to other forms of energy that come from non-renewable resources that are rapidly depleting. In the following essay I will enforce my opinion in the subject and attempt to convince

The Disasters of War (Spanish: Los Desastres de la Guerra) are a series of 82[a 1] prints created between 1810 and 1820 by the Spanish painter and printmaker Francisco Goya (1746–1828). Although Goya did not make known his intention when creating the plates‚ art historians view them as a visual protest against the violence of the 1808 Dos de Mayo Uprising‚ the subsequent Peninsular War of 1808–14 and the setbacks to the liberal cause following the restoration of the Bourbon monarchy in 1814.

calamity‚ the debate on whether the industrialisation of the hill state had contributed to the disaster turned into a face-off between environmentalists and the chief minister Vijay Bahuguna‚ who claimed the tragedy was a natural calamity. "This is a very childish argument that cloudbursts‚ earthquakes and tsunamis are because of human factors. In the history of hundreds of years of Kedarnath‚ no such incident has taken place. In a Himalayan state‚ this catastrophe has come about in 37‚000 square miles

Introduction After the Fukushima nuclear reactor disaster‚ radioactivity and radioactive contamination have become a topic of our conversation. In the initial stage‚ people were terrified by it and spread bad gossip about it although they did not know what it is exactly. I think we should learn what radioactivity is and try to stop spreading incorrect information about it. I heard the words “The correct decision is made by the correct information and the correct analysis.” I agree with it‚ so I

extremely disastrous and cause a lot of damage in the place where they happen. The earthquake can happen once or happen as a series. This depends on the magnitude of the earthquake. There are other tremors that can cause an earthquake‚ for instance‚ nuclear bombs. These cannot be considered as earthquakes‚ as they are not naturally triggered (Coffey‚ 2010). The earthquake can be grouped into three stages. There is the foreshock‚ which come first. These can be termed as tremors that are slight and may

Even with all the different hazards in the world one of the keys to surviving them is effective emergency management preparedness. Through the years‚ disaster preparedness has seen many changes and many meanings; to be able to enhance future disaster preparedness we need to look at the past and the present
