What are the basic disasters of a tornado?

Answer 1

The tornado is itself a disaster. When a tornado strikes and area, buildings and vegetation in the path are damaged or destroyed. In a strong enough tornado debris from destroyed structures is carried by the wind at high speeds, adding to the destructive potential. In the aftermath there may be destroyed homes and businesses, roads blocked by debris, downed power lines, power outages, and sometimes fires from ruptured gas lines.
