Trenches excavated across fault scarps on a 13 ka delta surface at Brigham City, Utah, document 4 types of soil-catena phenomena. 2 soil catenas were used to evaluate the applicability of a continuity approach to paleoearthquake dating, by which
percentages of total development time represented by each soil at a fault scarp footslope could be estimated.

On the alluvial fan of Nahal Shehoret in the extremely arid region of the Negev desert, Reg soils developed on stable alluvial surfaces in colluvium along terrace risers and in colluvial units on a complex fault scarp were compared. IRSL dates
and layers of height have also been used. The colour map belonging to this article depicts exhumed denudation surfaces of different age, polycyclic relief, important scarps interpreted as erosional or fault scarps, and the valley pattern. A basic chronology
