Answer:
A disaster is a destructive event that occurs suddenly and involves loss of life and property. Disasters can be of two types, natural and man-made. It is a sudden accident or a natural catastrophe that causes great damage or loss of life.
*TYPES OF DISASTERS
MAN MADE DISASTERS
The man-made disasters are triggered by human beings. Some of the man-made disasters are: bomb explosions, terrorism, or civil war, leakage of poisonous chemicals, breach in ams, air or water pollution, industrial accidents and epidemics. They are known as man made disasters because they occur due to human actions and not natural forces.
NATURAL DISASTERS
Earthquakes, volcanic activity, tsunamis, floods, cyclones, landslides, avalanches and droughts are natural disasters and man has no control over them. They are a result of natural activities and hence known as natural disasters.
FLOODS
A flood is an overflow of a large amount of water beyond its normal limits, especially over what is normally dry land. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks leeves, resulting in some of that water escaping its usual boundaries.
EARTHQUAKES
An earthquake is a sudden tremor or movement of the earth's crust, which usually originates at below the surface. The outer layer of the earth is solid and is divided into many sections known X as plates. The point of origin of the earthquake within the crust or mantle is called the seismic focus. Since the focus is often deep below the surface, the location of the earthquake is often referred to as the point on the surface of the earth, vertically above the seismic focus. This point is called the epicentre.
