Code	Value	Description
CW	Cold Wave	Cold Wave is defined as a period of abnormally cold weather. Typically a cold wave lasts two or more days and may be aggravated by high winds. The exact temperature criteria for what constitutes a cold wave vary by location.
DR	Drought	Drought is defined as an extended period of unusually low precipitation that produces a shortage of water for people, animals and plants. Drought is different from most other hazards in that it develops slowly, sometimes even over years, and its onset is generally difficult to detect. Drought is not solely a physical phenomenon because its impacts can be exacerbated by human activities and water supply demands. Drought is therefore often defined both conceptually and operationally. Operational definitions of drought, meaning the degree of precipitation reduction that constitutes a drought, vary by locality, climate and environmental sector.
EW	Earthquake	Earthquake is defined as sudden movement of a block of the Earth’s crust along a geological fault and associated ground shaking.
EP	Epidemic	Epidemic is defined as either an unusual increase in the number of cases of an infectious disease, which already exists in the region or population concerned; or the appearance of an infection previously absent from a region.
ET	Extratopical Cyclone	Extratropical Cyclone is defined as a type of low-pressure cyclonic system in the middle and high latitudes (also called mid-latitude cyclone) that primarily gets its energy from the horizontal temperature contrasts (fronts) in the atmosphere. When associated with cold fronts, extratropical cyclones may be particularly damaging (e.g. European winter/windstorm, Nor’easter). (CRED EM-DAT)
FR	Fire	Fire is defined as urban, industrial or rural fires, linked to natural phenomena, such as electrical storms, earthquakes, droughts, etc.but not including wild fires, which refer to uncontrolled fire in rural areas, forests, plains, etc. Directly human-induced fires are classified as Technological Disaster.
FF	Flash Flood	Flash Flood is defined as rapid inland floods due to intense rainfall A flash flood describes sudden flooding with short duration. In sloped terrain the water flows rapidly with a high destruction potential.
FL	Flood	Flood is a general term for the overflow of water from a stream channel onto normally dry land in the floodplain (riverine flooding), higher-than- normal levels along the coast and in lakes or reservoirs (coastal flooding) as well as ponding of water at or near the point where the rain fell (flash floods).
HW	Heat Wave	Heat Wave is defined as a prolonged period of excessively hot and sometimes also humid weather relative to normal climat patterns of a certain region. Heat waves like in Central Europe 2003.
IN	Insect Infestation	Insect infestation is defined as the pervasive influx and development of insects or parasites affecting humans, animals, crops and materials.
LS	Land Slide	Land Slide is defined as the usually rapid downward movement of a mass of rock, earth, or artificial fill on a slope. Covers all mass movements other than Mudslide (MS) and Avalanche (AV).
MS	Mud Slide	Mud slide is defined as a type of landslide, which occurs when the slope is saturated with water. This more destructive flow can pick up rocks, trees, houses and cars. As the debris moves into river and stream beds, bridges can become blocked or even collapse, making a temporary dam that can flood neighbouring areas.
OT	Other	Other is defined as all natural disasters that do not fall into any of the other disaster types. Special situations such as energy crisis, etc.
ST	Sever Local Storm	A severe storm or thunderstorm is the result of convection and condensation in the lower atmosphere and the accompanying formation of a cumulonimbus cloud. A severe storm usually comes along with high winds, heavy precipitation (rain, sleet, hail), thunder and lightning.
AV	Snow Avalanche	Snow Avalanche is defined as mass of snow and ice falling suddenly down a mountain slope and often taking with it earth, rocks and rubble of every description.
SS	Storm Surge	Storm Surge is defined as the rise of the water level in the sea, an estuary or lake as result of strong wind driving the seawater towards the coast. This so-called wind setup is superimposed on the normal astronomical tide. The mean high water level can be exceeded by five and more metres. The areas threatened by storm surges are coastal lowlands.
AC	Technological Disaster	Technological disasters are only covered on a very exceptional basis, such as oil/toxic spills and gas explosions, when they have a major humanitarian impact in highly vulnerable countries.
TC	Tropical Cyclone	"Hurricane", "cyclone" and "typhoon" are different terms for the same weather phenomenon which is accompanied by torrential rain and maximum sustained wind speeds (near centre) exceeding 119 kilometers per hour: In the western North Atlantic, central and eastern North Pacific, Caribbean Sea and Gulf of Mexico, such a weather phenomenon is called "hurricanes"; In the western North Pacific, it is called "typhoons"; In the Bay of Bengal and Arabian Sea, it is called "cyclones"; In western South Pacific and southeast India Ocean, it is called “severe tropical cyclones”; In the southwest India Ocean, it is called “tropical cyclones.”
TS	Tsunami	Tsunami is defined as a series of waves (with long wavelengths when traveling across the deep ocean) that are generated by a displacement of massive amounts of water through underwater earthquakes, volcanic eruptions or landslides. Tsunami waves travel at very high speed across the ocean but as they begin to reach shallow water they slow down and the wave grows steeper.
VO	Volcano	Volcanic eruption with disastrous effects: eruption and emission of gas and ashes, stone falls (pyroclast), flows of lava, etc.
WF	Wild Fire	Wild Fire is defined as ny uncontrolled and non-prescribed combustion or burning of plants in a natural setting such as a forest, grassland, brush land or tundra, which consumes the natural fuels and spreads based on environmental conditions (e.g., wind, topography). Wildfires can be triggered by lightning or human actions.
