description The study of faults is a key aspect of earth science research. 3D models of fault systems have often been constructed in various geoscience studies to understand the underlying earth better. Plotting faults in seismotectonic maps helps to uncover the geological structure and dynamics of a region. Traditionally, these 3D fault models and maps are made through tedious processes or in expensive software inaccessible to many researchers. Tectoplot, a GMT-based, open-source seismotectonic plotting tool developed by Bradley (2021), has made it much easier to create seismotectonic maps, cross-sections and oblique block diagrams.
