This Data Release provides the compilation of offset measurement datasets and associated fault data to accompany the manuscript “Climatic influence on the expression of strike-slip faulting” by Reitman et al. In addition to a ReadMe file, it includes two tabular datasets, one code, and one text file. The datasets are a compilation of offset measurement data (“data_multiple_eq_offsets.xlsx”) from 31 studies of strike-slip faults with multiple earthquakes, and the associated fault data (“fault_data" provided in csv and xlsx formats) with inputs necessary to do the analysis described in the accompanying manuscript. The code (“code_multiple_eq_offsets.ipynb”) reads the offset measurement data from each sheet of “data_multiple_eq_offsets.xlsx” and fault data from “fault_data.xlsx”, performs analysis of the offset measurements data as described in the manuscript to calculate the exponential decay rate in the occurrence of large cumulative offsets (b values), and plots each offset measurement dataset and graphs included in the manuscript and supplementary information. The “references.txt” file provides the full reference for each study included in the compilation of offset measurements and used to compile information in “fault_data”.
