Natural disasters can often be predicted, which helps prevent damage. Hurricanes and tornadoes are two types of natural disasters. Many places in the United States are more prone to have tornadoes. Sometimes natural disasters happen without warning, such as the tsunami off the west coast of Sumatra, Indonesia. New systems are put into place when disasters like this occur.
