Slip Rate Category
Slip Rate Category : Defines one of four slip-rate categories, as determined by the compiler, or based on reported slip rates. The categories include (1) less than 0.01 mm/yr, (2) 0.01 to less than 0.1 mm/yr, (3) 0.1 to 0.2 mm/yr, and (4) greater than 0.2 mm/yr. "Comments" include a brief description of the basis for the compiler's selection, or reference to relevant published slip rates and associated documentation. Generally, two types of slip rates are reported. The first type is herein termed a "geologic slip rate" and is typically derived from the age and amount of offset of geologic features. These rates are averages of slip over several to many earthquake cycles. The second type defines an interval or "paleoseismic slip rate" that is calculated on the basis of known times and amounts of slip for two or more prehistoric earthquakes.
