The data about storm events between 1950 and Nov 2011 were obtained from the U.S. National Oceanic and Atmospheric Administration's (NOAA) storm database. The data contained information about injuries and fatal cases as well as property and crop damage caused by meteorological events. The type of each event was also specified in the original data. In this research, event types were grouped into 48 categories specified by [NOAA](http://www.ncdc.noaa.gov/stormevents/details.jsp?type=eventtype) and total health or economical damage was estimated for each category. Results show that Tornado, Thunderstorm Wind, Excessive Heat, Flood, Lightning, Heat and Flash Flood were most harmful with respect to population health, while Flood, Hurricane (Typhoon), Tornado, Storm Surge/Tide, Hail, Flash Flood and Drought caused most damage in the economical context.
