Simple Models of Complex Slip Distribution? A Case Study of the 2011 Mw 7.1 Van (Eastern Turkey) Earthquake

We evaluate the presently proposed simple models for slip distribution, including the homogeneous slip model, the triangular slip model, the k-square model, the slip tip taper model, and the restricted stochastic source model, to investigate which is most consistent with ‘real-world’ slip distribution inverted. We take the 2011 Van (Eastern Turkey) Mw 7.1 earthquake as an example, considering six inversion results of slip distribution. The Akaike information criterion (AIC) is used to evaluate the models. The evaluation shows that for six inversion results, qualitatively, the k-square model, with three degrees of freedom, seems most consistent with the real-world slip distribution overall.
