This dataset includes 1295 records of topographic profiles organized in 23 fields reporting topography, rupture zone width, and cumulative vertical separation of 1983 coseismic ruptures (CoRs) and Quaternary fault scarps (Qfs) from the Lost River Fault, Idaho, USA.

Fault segment name: Text indicating the acronym of the fault segment along which the measurement was acquired; (Challis Segment = CS; Warm Springs Segment = WSS; Thousand Springs Segment = TSS; Mackay Segment = MS; Pass Creek Segment = PCS; Arco Segment = AS; Lone Pine Fault = LPF).Synthetic/Antithetic: The Lost River Fault is a SW-dipping fault; This field summarizes the information obtainable from the dip direction of each trace, as it categorizes all the traces with the same dip direction of the LRF (synthetic) and all the traces with dip direction opposite to the LRF (antithetic).
