What is a natural disaster?|
A natural disaster is the consequence or effect of a
hazardous event, occurring when human activities and
natural phenomenon, that does not affect humans,
takes place. The resulting factors, or property
damages, depend on the capacity of the population to
support or resist the disaster.
What is a tsunami?
A tsunami is a vast sea wave caused by the sudden
dropping or rising of a section of the sea floor
following an earthquake. These waves may reach
enormous dimensions and have sufficient energy to
travel across entire oceans. Tsunami may be as much
as 30 meters high and 200 kilometers long, may move
as fast as 250 kilometers per hour, and may continue
to occur for as long as a few days. The word is
Japanese and means harbor wave, because of the
devastating effects these waves have had on low-
lying Japanese coastal communities.
