Impact of source characterization, structure, and building type on the shape of macroseismic region of 1990 7.3 Mw Rudbar, Iran Earthquake

This dataset supports the analysis of the mechanisms responsible for the asymmetrical macroseismic distribution of the 1990 Mw 7.3 Rudbar earthquake. The event ruptured an ~80 km long, near-vertical left-lateral strike-slip fault, yet produced a damage zone exhibiting significant asymmetry both along and across the fault strike. This study investigates the physical processes—namely source effects, seismic wave propagation, and building typology—that controlled the observed damage patterns. The data consists of two primary components. The rudbar_cluster_data.tar.gz file contains seismic phase arrival times (each event stored in a corresponding .mnf file) and all ancillary files for the mloc program, including station coordinates (stn.dat), the velocity model (rudbar.cr), and the program's output files. The relocation of the aftershock sequence using this data revealed a southeast-trending rupture directivity and greater moment release in the eastern fault segment, explaining the along-strike asymmetry. The Villages_City_Killed_Destructed_Corrected.csv file is a comprehensive macroseismic inventory detailing building damage and fatalities per settlement; this data was used to produce Figures 2, 3, 4, Table 1, and Tables S2/S3. The spreadsheet headers explain each column. Collectively, this data enables the interpretation of how source rupture properties, seismic wave propagation, and local site conditions controlled the observed damage patterns.
