There are two types of disasters: Natural and Manmade or Human Induced Disasters. Disasters that occur due to abrupt changes in the earth systems and weather conditions are called as natural disasters. These disasters have further been classified into – Planetary and Extra-Planetary Disasters.
Disasters that occur on land and in atmosphere due to changes in earth systems or the geological conditions and atmosphere are called as Planetary Disasters. These disasters have further been classified into – Terrestrial and Atmospheric disasters.
Disasters that remain confined to land and bottoms of oceans are called as terrestrial disasters. Volcanic eruptions, earthquakes, tsunamis, landslides and mine disasters are some examples of terrestrial disasters. Atmospheric disasters are caused due to atmospheric events. Tropical cyclones, droughts, floods etc. are some examples of atmospheric disasters. Disasters occurring due to collisions between the earth and space bodies or due to physical forces between them are called as extra-planetary disasters. High tide waves, hurricanes, landslides, movements of rocks, changes in sea level, biological extinctions etc. are examples of extra- planetary disasters.
Disasters that are caused due to human intervention in the natural processes or due to his activities related to development and war are called as man- made disasters. Occurrence of epidemics, nuclear hazards, industrial accidents, biological war fares, bioterrorism etc. are man- made or human induced disasters. In modern age, so many of the natural disasters like earthquakes etc. have become man- made disasters due to human activities of building mega dams and large scale developmental projects.

Disaster Capitalism

...Disaster capitalism The two terrible natural disasters occurred recently in Haiti and Chile, together with the coup de eta in Honduras, plus the reaction of USA about this critical situations, have reawakened the fear that Latin America might be completely directed to the application of the doctrine of the “Disaster Capitalism”. According to Naomi Klein, capitalism has triumphed in the world not because the nations had willing accepted it, but because the ‘rules of the game’ of capitalism have been imposed in the form of liberal market politics. This is true especially in moments of disasters produced or used as an excuse for impose these politics. The fundamentalists of capitalism believe that the countries crashed by natural disasters become very ductile and easy to influence politically speaking. According to Naomi Klein, this is the way how big nations ideologically take over small crushed countries. No matter what our thoughts about her claims might be, we cannot ignore the fact that calamities like the attack to NYC in 2011, the Iraq and Afghanistan wars, the AH1N1 pandemic and let us not forget the devastation of New Orleans by hurricane Katrina, were used as mere business opportunities by American companies. These companies try to profit even if it means taking advantage of pitiful situations. The terrible events occurred during the September 11 attacks in NYC, no matter if they were product of an evil force or a self-attack, fitted like a glove to the plans......

Disaster Recovery

...Disaster recovery plans allows and gives the opportunity to a business to be able to recoup from any number of disasters, whether it may be a natural disaster or a fault of equipment to include power loss. These plans can be fairly basic with a goal and summary of what is to happen in the event of a disaster, to intensely involved and well spelled out plans that break down the summary, personal, intent, goal, and a timeline of events to follow. While disasters are unforeseen events that a business may never see or have to implement their plan, it allows them to be setup for success if it were to happen and not be doomed for failure in hopes of it not being a possibility. For this report, contact was made with Richmond County in Augusta Georgia to their IT department to discuss their disaster recovery plan. Some organizations are well equipped and have staffed members that specialize and have sole intent on being the disaster recovery planner and implementer.

The Bhopal Disaster

...human error and design error. The Bhopal disaster is one of the greatest scourge in history caused by a set of simultaneous failures. It happened in the night of 3rd of December at the Union Carbide plant in Bhopal, India in 1984. The disaster led to a truly massive loss of human life. At least 15000 people were killed and hundreds thousands were injured. Besides, the long-term economic, social, and psychological damages to the community and to the company’s employee were staggering. In some ways, the investigation of this hazard indicated that the design of this chemical plant did not follow the Engineering Design Process. The people of Bhopal were killed by a gas called MIC (methyl isocyanate). MIC is highly toxic and its vapor can cause many diseases, such as blindness, lung damage, physical traumas. That very night, more than 25 tons of an MIC vapor/liquid mixture were released to the atmosphere. Not only human, but also the animals perished in the disaster, poisoned by the huge gas leak. A large number of people are still suffering from the disaster after thirty years. Many of those who were exposed to the gas have given birth to physically and mentally disabled children. After the disaster, the Indian justice system spent twenty five years on criminal trial and reached a conclusion. The Union Carbide plant agreed to pay $470 million to the victims of the disaster and their families. Some activists and victims of the Bhopal disaster were not satisfied with the......

A leak of methyl isocyanate gas and other chemicals from the plant resulted in the exposure of hundreds of thousands of people. The toxic substance made its way in and around the shantytowns located near the plant.[2] Estimates vary on the death toll. The official immediate death toll was 2,259 and the government of Madhya Pradesh has confirmed a total of 3,787 deaths related to the gas release.[3] Others estimate 3,000 died within weeks and another 8,000 have since died from gas- related diseases.[4][5] A government affidavit in 2006 stated the leak caused 558,125 injuries including 38,478 temporary partial and approximately 3,900 severely and permanently disabling injuries.[6] UCIL was the Indian subsidiary of Union Carbide Corporation (UCC), with Indian Government controlled banks and the Indian public holding a 49.1 percent stake.

The Chernobyl Disaster

...The Chernobyl Disaster Yesterday, Today, and Tomorrow Written by: Heather Stover ENG135 October 2012 Professor Spencer Robinson Twenty-six years ago in April of 1986 the city of Chernobyl, located in north-central Ukraine on the Pripyat River, was virtually unknown. It was just an obscure city that you and I would never have known existed. Almost incidentally, the name of this city was attached to the V.I. Lenin Nuclear Power Plant located about twenty-five kilometers upstream from the city of Chernobyl. On April 26, the city's anonymity vanished forever when, during a test at 1:21 A.M., the No. 4 reactor exploded and released thirty to forty times the radioactivity of the atomic bombs dropped on Hiroshima and Nagasaki. This was due to the flawed reactor design in use at the plant. The world first learned of history's worst nuclear accident from Sweden, where abnormal radiation levels were registered at one of its nuclear facilities. (Adams, 1996) Ranking as one of the greatest industrial accidents of all time, the Chernobyl' disaster and its impact on the course of events for the Soviets can hardly be exaggerated. No one can predict what will finally be the exact number of human victims. Thirty- one lives were lost immediately, although it was initially reported as only two and the others were to have died from acute radiation poisoning. Hundreds of thousands of Ukrainians, Russians, and Belorussians had to abandon entire cities......

Natural Disasters

...natural disasters". To call a disaster ‘natural’, means that it has occurred completely independent of the influence of humans. The damage caused by Hurricane Katrina, cannot solely be held accountable by a force of nature, however destructive. Human factors have had an equally damaging effect on the affected areas. It is clear to anyone studying natural disasters that, the difference between who lives and who dies depends largely if not completely on which side of the social divide you were born into. Reasons for evacuation and disaster preparation must be reviewed as these subjects are what caused the most damage. Many believed that the storm wasn’t a serious threat, this could be due to naivety and lack of education on the storm itself. While others, especially those lacking financial backing believed that taking a calculated risk was their best option, the risk of course being calculated by; cost and scepticism. While the richer demographic owned cars to evacuate, credit cards for supplies and refuge, and their immediate families were far more likely to have the resources available to support their evacuation. Governmental, NGO’s and Private Organisations are also held responsible for city preparedness.

The Bhopal Disaster

...Principles of management assignment What happened and Why? During the night of 2-3 December 1984, a leak of some 40 tons of Methylisocyanate (MIC) gas mixed with unknown other gasses from a chemical factory caused one of the highest-casualty industrial accidents of the 20th century. The Bhopal disaster was a gas leak incident in India, considered as the world's worst industrial disaster ever known to mankind. At least 2000 people died immediately and another 200.000 to 300.000 people suffered respiratory or got other injuries. The incident started by the ventilation of the poisonous gas to the atmosphere, namely Methylisocyanate (MIC). As the density of the gas is more than the density of the air itself, it has caused the accumulation of the toxic gas in a cloud form but it is close to the ground. Eventually the cloud of poisonous MIC gas streamed through the entire city of Bhopal like a sand storm on desert, leaving no chances for the citizens of Bhopal to rescue themselves The initial Indian managing and supervisory staff for the Bhopal production unit were trained in Union Carbide’s West Virginia. They began leaving for more attractive jobs and were replaced by less-skilled employees. Low production volumes seemed to justify reductions in the workforce though the local labor unions insisted that they were going too far. In the MIC, the workforce was reduced from the Union Carbide recommended...

In 2012, the country was among the top three countries affected by natural disasters. The December 2012 storm alone displaced over 6.2 million people and caused nearly $1.7 million in damages. Through proactive legislation and policies, the Philippines has managed to sustain the lowest loss of the top ten countries in GDP at only .29%. The most influential policy regulating natural disaster response is the Republican Act 10121 (Disaster Risk Reduction and Management/DRRM Act). Preceding the DRRM Act, Presidential Decree 1566 established disaster coordinating councils that established links to government and civic organizations in order to mobilize resources to provide support during disasters. The National Disaster Coordinating Council or NDCC makes policies and coordinate efforts regarding disasters throughout the public and private sectors. Along with policies, laws and regulations have been implemented to curb death and property damage during natural disasters.
