Grouping and migration of surface faulting and variations in slip rates on faults in the Great Basin province

Abstract

Abstract Nonuniformity of the occurrence of large slip events producing surface ruptures on seismogenic faults and variations in slip rate probably characterize seismogenic faulting in the Great Basin province, Western United States. Examples include: the grouping of faulting events along the Lost River fault, Idaho; changes in tilt rates of the East Range and Cortez Mountains, Nevada; extension of slip along a fault on the northwest flank of the Humboldt Range, Nevada; and migration or shifting of slip back and forth from one fault to another along subparallel range-front faults, in Dixie Valley, Nevada.
