Some after-effects of tornadoes are fatalities and injuries to people and animals, damaged or destroyed buildings, water supply contamination and loss of services. Ongoing effects include displacement, illness and disruption of everyday life.
According to meteorologists, a tornado is the most severe type of storm. Depending on its severity, a tornado can cause a host of extenuating issues and leave behind a path of destruction up to 1 mile wide and 50 miles in length. High winds cause objects to become airborne, which can result in injuries and loss of life. Flying objects also cause property damage, as does the wind itself.
Tornadoes often damage or destroy power and phone lines. They can also cause gas lines to rupture, posing an immediate risk of fire and explosion. Intense wind can even cause a region's water supply to become compromised, creating a serious health issue. Emergency services and rescue efforts are often hindered because of damage to buildings, equipment, vehicles and roadways. Responders may be injured in a tornado and unable to aid others.
If a tornado warning is issued for an area, residents are advised to seek shelter in a basement if possible. For homes with no basement, a small centralized room or hallway on the ground floor is best.
