This is a MATLAB reproduction of the spatial-temporal ETAS model proposed by Teacher Zhuang in 2002, which is more concise and easier to understand

This is the code for the stress release model and its extended model; the generation of the simulation directory is based on the method of Barani (2025), and information can be obtained in the rele…

I previously wrote a version of the ETAS simulation; the two are very similar but have certain differences, and both can be used for seismicity modeling.

Spatial b-value calculation using penalized likelihood function
MATLAB
The idea behind Quasi-Newton methods is to approximate the Hessian matrix at each iteration by incorporating gradient information into the Newton method, thereby avoiding the need for direct comput…
