News media and government spokes people often tell us about the catastrophes that happen, but not always the why's or how's. Here all types of disasters will be defined and explained. As well as the outcomes of being prepared or unprepared are coming soon, so check back often. A good idea in any case, is to have a weather or emergency radio to stay up to the minute on environmental changes or concerns.
Often caused by heavy seasonal rains, floods are commonly seen during the time between March and August. Floods are powerful, large volumes of flowing water following the natural flows of local rivers or streams when they break over their banks. For more information on floods and tsunamis click here.
Defined as an epidemic of infectious disease that spreads through populations across a large region in a short period of time often within weeks. For more information on Pandemics and dealing with contaminants after a disaster click here.
A hurricane is a type of tropical cyclone, the generic term for a low pressure system that generally forms in the tropics. A typical cyclone is accompanied by thunderstorms, and in the Northern Hemisphere, a counterclockwise circulation of winds near the earth’s surface. For more information on hurricanes click here.
A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees. Damage paths can be in excess of one mile wide to 50 miles long. In an average year, 1000 tornadoes are reported nationwide. For even more information on tornados and heavy storms click here
Usually the causes for a tsunami when they occur under water; earthquakes are the violent release of energy from the friction of the earth’s crust at stress points. These points are called faults. But earthquakes are also the result of volcanoes, tectonic plate movement and seismic activity in the mantle.
Simply put, volcanoes are the release of magma, debris, gases and earth from a given point on the surface of the planet; sometimes on land mainly underwater. Lava flows are different from volcanic activity because flows are often predictable and slow moving while volcanoes are almost always violent and destructive.
A tsunami is a wave train, or series of waves, generated in a body of water by an impulsive disturbance that vertically displaces the water column. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis. Tsunamis can savagely attack coastlines, causing devastating property damage and loss of life. For information on floods associated with tsunamis and more click here.
A slide of large masses of snow and ice and mud down a mountain, sometimes a mud slide is considered an avalanche as well. Avalanches often gather into a huge mass and roll down a mountain after a large snow fall, heavy rains (mud slide) or warming of snow as it breaks from rocks.
A drought is defined as a period of abnormally dry weather sufficiently prolonged for the lack of water to cause serious hydrologic imbalance in the atmosphere. The dust bowl of the early 1930’s was a drought as well as the Australian brush fire of earlier this year was caused by drought.
There are really two different meanings for the word "blizzard". "Blizzard conditions" occur when strong winds (at least 35 mph) combine with either falling snow or snow on the ground to reduce visibilities to 1/4 mile or less for at least three hours. According to this definition, blizzard conditions can occur without falling snow, it's severe blowing snow.
The other meaning of "blizzard" is a strong winter cyclone event combined with high winds that cause a lot of blowing and drifting of snow. Ice storms a similar but are large cells of rain or moisture that condenses and freezes when it contacts a surface.
Often seen as a spreading wall of fire, firestorms and wild fires are the burning of combustible material across large areas of land. Fire walls are most commonly a natural phenomenon, created during some of the largest bushfires, forest fires, and wildfires. For more in depth information on protecting against fires click here.
As has been evidenced in recent months, economic disasters have wide spread and multifaceted aspects. Often, we associate disasters with nature or astrological events, but nothing hits harder at home than the loss of a job, unanticipated expenses, death of a primary financial care giver, or exponential debt.

H1N1 & Mothers
"Pregnant mothers are slated to be included in the first round of H1N1 flu vaccines, but do not forget that these shots are tests, we've never had this strain of flu. We haven't had a serious pandemic in a years, we [humanity] is overdue."
