According to infoplease, tornadoes can cause very minimal damage, such as ripping siding off of homes, to catastrophic damage, which can literally lift homes off their foundations. The type and severity of tornadoes are classified using the Fujita scale. On this scale, tornadoes are rated from F0 to F5, with F5 being the most dangerous and deadly.Continue Reading
Depending on the type of tornado involved, the types of damage incurred can vary dramatically. For example, F2 and F3 tornadoes can have wind speeds of up to 112 mph, which is strong enough to overturn cars and mobile homes, as well as tear the roofs off of houses and twist and uproot trees. Tornadoes designated as F0 and F1 do very little damage, but may result in broken tree limbs and damaged signs. They may even blow off a few shingles.
The most deadly tornadoes, on the other hand, only account for 1 percent of funnel clouds. These storms are rated F4 and higher. These storms have funnels that measure in excess of a mile wide and carry winds in excess of 261 mph. These storms completely level communities and hurl objects considerable distances. They also account for more than 70 percent of tornado fatalities.Learn more about Storms
Avalanches can cause catastrophic damage to homes, habitat and property, as well as cause human deaths. Avalanches can cause flash floods if the debris reaches rivers or lakes and causes the water level to rise. Additionally, avalanches cause economic problems, as communities must spend considerable resources to rectify the damage caused by the falling snow and ice.Full Answer >
According to a 2006 Census Bureau study, the damage left by Hurricane Katrina caused over 400,000 people throughout the Gulf Coast region to lose their homes. Many former residents remain displaced as of 2014, as the affected areas are still in the process of redevelopment.Full Answer >
Hurricanes cause severe damage to man-made structures and the natural environment, and they can uproot trees, destroy walls, upturn vehicles, erode beaches and cause inland flooding. Very strong hurricanes can devastate houses, reduce water supply and lead to power outages that last weeks.Full Answer >
Tornadoes form out of thunderstorms, where moist air rises, cools and condenses into clouds that release heat and force cooler air back down. If the updrafts are strong enough, the feedback loop forms an air vortex that continues to shunt more moist air upwards and eventually forms a tornado.Full Answer >
