pysimulator

Simulator package for earthquake catalogs with Epidemic-Type Aftershock Sequence (ETAS) - Salvatore Iacoletti

These codes were used to produce the results published in Iacoletti et al. (2022):

• pyetas was used to calibrate the ETAS models;
• pysimulator was used to simulate synthetic catalogs using the calibrated ETAS models.

Available functionalities

• Simulation starting from single event scenario or full-scale earthquake catalogs;
• Simulation of events taking into account the geometry of the fault ruptures. A few examples of fault geometry are shown in Iacoletti et al. (2022);
• Simulation of various types of ETAS models, especially the one described in Iacoletti et al. (2022), including short-term incompleteness, truncated time and magnitude distributions;
• Flexible: pysimulator is object-oriented for easy implementation of new functionalities in the future;
• Spatially varying background seismicity;
• Simulation of nodal planes and depths.

Future improvements

• Add more examples to showcase pysimulator capabilities;
• Complete Zhuang-type background seismicity;
• Full hazard/risk calculations (most likely, this will be in a different public repository);
• Graphic User Interface (GUI): in development.
