| Cat | category variable indicating the method used in distance calculation of a particular event. A: All fault attributes are extracted from a preferred finite fault model (see discussions below); randomization of fault attributes is not necessary . B: The strike/dip/rake of preferred fault plane is selected from the available fault plane solutions; random sampling of fault area, fault length, and hypo position on fault are made according to the distributions described in CY2008. C: Fault plane solution is available, but preferred plane is unresolved; in addition to the random sampling of category B, random selection over the two possible planes (0.5/0.5 weight) is made. D: Fault plane solution is unavailable; fault plane geometry and faulting mechanism are inferred from historical average; in addition to the randomization of category B, random sampling of strike (from a uniform distribution between +- 30 degrees of inferred value) and dip (from a uniform distribution between +- 10 degrees of inferred dip) E: Neither fault plane solution nor historical average are available; random samples of mechanism (which is then used to set the dip angle), strike, fault length, fault area, and hypocenter position on fault are made. |
