Intensity assignments from historical earthquake data: issues of certainty and quality

摘要: The use of macroseismic data in assessing parameters for historical earthquakes seismic hazard assessment has thrown more attention on the way which these are treated. processes involved selecting from a earthquake survive to present day can be modelled as a series filters, most outside control seismologist/historian, and cause distortion in resulting picture earthquake. ways become distorted should taken into account when interpreting as intensity values. One usefully discriminate between certainty an assignment (how well fits scale) quality one trust that value is true reflection what really happened). expression uncertainty usually the form ranged values; requires extra symbol or rating some sort. A system presented three types problems: reliability assessment, locational uncertainty, veracity original data. Each treated binary variable, giving final code ranging 0 (best) 7 (worst). This single integer preserves information then expanded required by computer programs designed handle
