Debris or débris (UK: /ˈdɛbriː/ or /ˈdeɪbriː/; US: /dᵻˈbriː/) is rubble, wreckage, ruins, litter and discarded garbage/refuse/trash, scattered remains of something destroyed, discarded, or as in geology, large rock fragments left by a melting glacier etc. Depending on context, debris can refer to a number of different things. The first apparent use of the French word in English is in a 1701 description of the army of Prince Rupert upon its retreat from a battle with the army of Oliver Cromwell, in England.
In disaster scenarios, Tornado leave behind large pieces of houses and mass destruction overall. This debris also flies around the tornado itself when it's in progress. The tornado's winds capture debris it kicks up in it's wind orbit, and spins it inside it's vortex. The tornado's wind radius is larger than the funnel itself. In fact some studies suggest that in EF-5 tornadoes, the radius of the tornado could be classified as a new EF-6 tornado. Tsunamis and hurricanes also bring large amounts of debris. Such as Hurricane Katrina in 2005 and Hurricane Sandy in 2012. Earthquakes rock cities to rubble debris. Overall natural disasters can be very difficult to recover from. But in the end, we can always pull through what Mother Nature throws at us.
