Abstract

We publish a MATLAB code used to analyze concentration profile of cosmogenic ³⁶Cl accumulated in-situ through a rupture history of the fault scarps in western Turkey (Mozafari et al., 2019). The code is a version of the forward modeling Matlab code -Fault Scarp Dating Tool- (Tikhomirov, 2014). The code models a ³⁶Cl profile accumulated in the fault scarp surface through a guessed rupture history, and compares the modeled and measured ³⁶Cl profiles with statistical tests. Rupture histories are randomly generated in bounded solution space using Monte-Carlo method or optimized using Random Walk algorithm to achieve the best fit of the modeled and measured ³⁶Cl profiles. The code has a user-friendly interface, a build-in help and an example of input data.
