The simulation seems to have essentially an infinite number of earthquakes, with the simulation amassing hundreds of earthquakes in a tenth of a year interval.\r\n\r\nThis project first requires VALIDATION of the aftershock code, then a simple implementation of a simulation with and without aftershocks and quantifying the statistics.\r\n\r\nAftershock code is very short and simple, and is located in src/simulation/RunEvent.cpp in the `processAftershock()` function. There is also some code in src/simulation/BASSAftershocks.h and src/simulation/BASSAftershocks.cpp "}}
