Disaster

A disaster is a serious disruption occurring over a short or long period of time that causes widespread human, material, economic or environmental loss which exceeds the ability of the affected community or society to cope using its own resources. Developing countries suffer the greatest costs when a disaster hits – more than 95 percent of all deaths caused by hazards occur in developing countries, and losses due to natural hazards are 20 times greater in developing countries than in industrialized countries.

Catastrophism

Catastrophism is the theory that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope. This is in contrast to uniformitarianism, in which slow incremental changes, such as erosion, created all the Earths geological features. The proponents of uniformitarianism held that the present was the key to the past, and that all geological processes throughout the past were like those that can be observed now. Since the early disputes, a more inclusive and integrated view of geologic events has developed, in which the scientific consensus accepts that ...

Crash cover

A crash cover is a philatelic term for a type of cover, meaning an envelope or package that has been recovered from a fixed-wing aircraft, airship or aeroplane crash, train wreck, shipwreck or other accident. Crash covers are a type of interrupted mail. Crashes of flights carrying airmail were a regular occurrence from the earliest days of mail transport by air. In many cases of aircraft crashes, train wreck and shipwrecks, it was possible to recover some or even all of the mail being carried, with perhaps some charring around the edges of some pieces if there had been a fire, or water dam ...

Disaster area

A disaster area is a region or a locale, heavily damaged by either natural, technological or social hazards. Disaster areas affect the population living in the community by dramatic increase in expense, loss of energy, food and services; and finally increase the risk of disease for citizens. An area that has been struck with a natural, technological or sociological hazard that opens the affected area for national or international aid.

Engineering disasters

Shortcuts in engineering design can lead to engineering disasters. Engineering is the science and technology used to meet the needs and demands of society. These demands include buildings, aircraft, vessels, and computer software. In order to meet society’s demands, the creation of newer technology and infrastructure must be met efficiently and cost-effectively. To accomplish this, managers and engineers have to have a mutual approach to the specified demand at hand. This can lead to shortcuts in engineering design to reduce costs of construction and fabrication. Occasionally, these shortc ...
