Tornado

tornadoestornadicCyclone
In disaster scenarios, tornadoes leave behind large pieces of houses and mass destruction overall.
Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than 110 mph, are about 250 ft across, and travel a few miles (several kilometers) before dissipating.

Landslide

landslideslandslipdebris avalanche
In geology, debris usually applies to the remains of geological activity including landslides, volcanic explosions, avalanches, mudflows or Glacial lake outburst floods (Jökulhlaups) and moraine, lahars, and lava eruptions.
As the impoundments fail, a "domino effect" may be created, with a remarkable growth in the volume of the flowing mass, which takes up the debris in the stream channel.

Scree

When it accumulates at the base of hillsides, it can be called "talus" or "scree".
Talus deposits typically have a concave upwards form, while the maximum inclination corresponds to the angle of repose of the mean debris size.

Mudflow

In geology, debris usually applies to the remains of geological activity including landslides, volcanic explosions, avalanches, mudflows or Glacial lake outburst floods (Jökulhlaups) and moraine, lahars, and lava eruptions.
Fine grainy material or soil has a smaller friction angle than a coarse sediment or a debris flow, but falling rock pieces can trigger a material flow, too.

Pollution

Marine debris applies to floating garbage such as bottles, cans, styrofoam, cruise ship waste, offshore oil and gas exploration and production facilities pollution, and fishing paraphernalia from professional and recreational boaters.
A much more recently discovered problem is the Great Pacific Garbage Patch, a huge concentration of plastics, chemical sludge and other debris which has been collected into a large area of the Pacific Ocean by the North Pacific Gyre.

The largest concentration of marine debris is the Great Pacific Garbage Patch.
The patch is characterized by exceptionally high relative pelagic concentrations of plastic, chemical sludge, and other debris that have been trapped by the currents of the North Pacific Gyre.
