Question

of disaster types and it's definition please answer in detail​

Answer 1

By definition, a natural disaster is an event that is caused by the natural forces of the earth and results in great damage and possibly loss of life. Each year, the earth experiences natural disasters. When natural disasters occur in heavily populated areas, a lot of people may lose their lives. A recent example is the Italian earthquake of 2016, where over 200 people died. The deadliest of all earthquakes happened in 1556 in China, where approximately 830,000 people lost their lives.

Let's now take a look at the different types of natural disasters that can happen.

Earthquakes

We'll begin with earthquakes. An earthquake occurs when the earth releases pent-up energy and causes the ground to shake. Earth's ground is made up of several very large pieces of land called tectonic plates. Most earthquakes occur when these plates rub against each other in some way. These same plates also create mountains when they push against each other. As the mountains are formed, earthquakes may be felt. Sometimes, people cause earthquakes when they do mine blasts or nuclear tests.

Answer:

Types of Disaster

Natural Disasters

According to the International Federation of Red Cross & Red Crescent Societies Natural Disasters are naturally occurring physical phenomena caused either by rapid or slow onset events that have immediate impacts on human health and secondary impacts causing further death and suffering. These disasters can be

Geophysical (e.g. Earthquakes, Landslides, Tsunamis and Volcanic Activity)

Hydrological (e.g. Avalanches and Floods)

Climatological (e.g. Extreme Temperatures, Drought and Wildfires)

Meteorological (e.g. Cyclones and Storms/Wave Surges)

Biological (e.g. Disease Epidemics and Insect/Animal Plagues)

The United Nations Office for Disaster Risk Reduction characterise Natural Disasters in relation to their magnitude or intensity, speed of onset, duration, and area of extent e.g. Earthquakes have short durations and usually affect a relatively small region, whereas Droughts are slow to develop and fade away and often affect large regions

Man-Made Disasters

Man-Made Disasters as viewed by the International Federation of Red Cross & Red Crescent Societies are events that are caused by humans which occur in or close to human settlements often caused as a results of Environmental or Technological Emergencies. This can include

Environmental Degradation

Pollution

Accidents (e.g. Industrial, Technological and Transport usually involving the production, use or transport of hazardous materials)
