The amount of Disasters in the world is raising at a very alarming rate. In 2000, there were an estimated 300 a year.
Major factors involved in this rise: Global warming, and climate change
Natural Disasters are fairly unpredictable. However, some disasters that involve weather are expected but most sneak up on us. Disasters come in many shapes and sizes. The damage of each disaster depends upon the severity of it.
A volcano is a mountain that has opened downward into an area of molten rock under the earth’s surface. If pressure builds and builds it will cause an explosion of different gases and rocks into the air. These can then turn into lava fragments causing a disastrous explosion filled with lava flows, hot ash, etc. Eruptions of these beast can be the leading cause in other disasters such as flashfloods, earthquakes, etc.
A tornado is one of nature’s most violent storms and must not be taken lightly. Tornadoes form from strong thunderstorms and involve small or large funnel shaped clouds. Tornadoes can produce deadly winds up to the excess of 300 miles per hour. They can cause massive amounts of damage, and residents usually have some type of short warning before they hit. Some states are at more risk than others due to layout of the mountains and plains.
Tsunami’s usually occur after a large disturbance occurs in earths atmosphere (ex. Earthquake, or volcano). They are filled with huge waves that are classified as “ripples” traveling from their beginning points. The waves travel at fast speeds through the sea and upon entering shallow waters they grow to enormous sizes and are very dangerous.
Flooding happens where there are raining in excess that occur over a period of time or a bunch of rain that falls at one time. To much rain can cause overflowing of waterways, levee breaks, or cause a dam to break. Flooding is the most common natural disaster there are and can happen anywhere. Floods are very dangerous!
Earthquakes involves violent shaking of earth’s surface. Earthquakes occur near “fault lines” of earth’s crust and are one of the most violent disasters there are; one main reason is because they can not be PREDICTED. If one happens you have no warning at all, and it makes it more of a surprise. They can be felt over large areas and usually don’t last very long.
