The Rohn Emergency Scale〔Rohn, Eli and Blackmore, Denis (2009) (A Unified Localizable Emergency Events Scale ), ''International Journal of Information Systems for Crisis Response Management'' (IJISCRAM), Volume 1, Issue 4, October 2009〕 is a scale on which the magnitude (intensity)〔(【引用サイトリンク】 FEMA Intensity Scales )〕 of an emergency is measured. It was first proposed in 2006, and explained in more detail in a peer-reviewed paper presented at a 2007 system sciences conference.〔Gomez, Elizabeth, Plotnick, Linda , Rohn, Eli, Morgan, John, and Turoff, Murray (2007). (Towards a Unified Public Safety Scale ), Hawaii International Conference on System Sciences (HICSS), Waikoloa, Hawaii.〕 The idea was further refined later that year. The need for such a scale was ratified in two later independent publications.〔Turoff Murray and Hiltz Roxanne (2008). (Assessing the health information needs of the emergency preparedness and management community ). ''Inf. Serv. Use'' 28, 3-4 (Aug. 2008), 269-280.〕〔Turoff, M., White, C., Plotnick, L., and Hiltz, S. R., (Dynamic Emergency Response Management for Large Scale Decision Making in Extreme Events ), ''Proceedings of ISCRAM 2008'', Washington D.C. May.〕 It is the first scale that quantifies any emergency based on a mathematical model. The scale can be tailored for use at any geographic level – city, county, state or continent. It can be used to monitor the development of an ongoing emergency event, as well as forecast the probability and nature of a potential developing emergency and in the planning and execution of a National Response Plan. == Existing emergency-related scales == Scales relating to natural phenomena that may result in an emergency are numerous. This section provides a review of several notable emergency related scales. They concentrate mainly on weather and environmental scales that provide a common understanding and lexicon with which to understand the level of intensity and impact of a crisis. Some scales are used before and/or during a crisis to predict the potential intensity and impact of an event and provide an understanding that is useful for preventative and recovery measures. Other scales are used for post-event classification. Most of these scales are descriptive rather than quantitative, which makes them subjective and ambiguous. : 1805 Beaufort scale〔(【引用サイトリンク】 publisher = National Oceanic and Atmospheric Administration, Storm Prediction Center )〕 : 1931 Modified Mercalli intensity scale〔(【引用サイトリンク】 publisher = U.S. Geological Survey, Earthquake Hazards Program )〕 : 1935 Richter magnitude scale〔(【引用サイトリンク】 publisher = U.S. Geological Survey, Earthquake Hazards Program )〕 : 1969 Saffir–Simpson hurricane wind scale〔(【引用サイトリンク】 publisher = National U.S. Oceanic and Atmospheric Administration - National Hurricane Center )〕 : 1971 Fujita scale〔(【引用サイトリンク】 publisher = National Oceanic and Atmospheric Administration )〕 (superseded by Enhanced Fujita scale in 2007〔(【引用サイトリンク】 The Enhanced Fujita Scale (EF Scale) )〕) : 1982 Volcanic explosivity index : 1990 International Nuclear Event Scale〔(IAEA fact sheet )〕 : 1999 Air quality index〔(【引用サイトリンク】 publisher = The U.S. EPA, NOAA and NPS AIRnow Project )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rohn Emergency Scale」の詳細全文を読む スポンサード リンク
