DESASTRES
Natural phenomena such as rain, earthquakes, hurricanes or wind, they become disasters when they exceed a limit of normal, usually measured by a parameter. [Citation needed] This variesdepending on the type of phenomenon, [citation needed] may be the seismic moment magnitude (Mw), the Richter scale for earthquakes, Saphir-Simpson scale for hurricanes, etc. [citation needed]
Somedisasters are caused by human activities that alter normal environment. Some of these are: environmental pollution, erroneous and irrational exploitation of renewable natural resources such as forestsand soil and non-renewable such as minerals, building homes and buildings in high-risk areas.
The effects of a disaster can be amplified due to poor planning of human settlements, lack of safetymeasures, emergency plans and warning systems manmade gets a little fuzzy.

TSUNAMI
A tsunami (plural: tsunamis or tsunami; from Japanese: 津波, lit. "harbour wave";[1] English pronunciation: /suːˈnɑːmi/soo-NAH-mee or /tsuːˈnɑːmi/ tsoo-NAH-mee[2]) is a series of water waves caused by the displacement of a large volume of a body of water, typically an ocean or a large lake. Earthquakes, volcaniceruptions and other underwater explosions (including detonations of underwater nuclear devices), landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have thepotential to generate a tsunami.[3]
Tsunami waves do not resemble normal sea waves, because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initiallyresemble a rapidly rising tide, and for this reason they are often referred to as tidal waves. Tsunamis generally consist of a series of waves with periods ranging from minutes to hours, arriving in aso-called "wave train".[4] Wave heights of tens of metres can be generated by large events. Although the impact of tsunamis is limited to coastal areas, their destructive power can be enormous and...
