Slab dehydration linked to great earthquake rupture barriers along the Alaska Peninsula

This repository contains tomography models, input and output files, the full LOTOS program (March 2018, release 2) (Koulakov, 2009, BSSA), and additional scripts written by the authors of this work. We are happy to provide the models as text files, please reach out Liam Moser. MAIN_MOD_EXTENDED_WHOLE_CAT_NO_OR_AFTERSHOCKS_CORR_TOPO – Preferred model MAIN_MOD_EXTENDED_WHOLE_CAT_CORR_TOPO – Model used in Fig. S2a with 2018 Mw7.9 Gulf of Alaska intraplate earthquake aftershocks SYN_VER1_EXTENDED_WHOLE_CAT_NO_OR_AFTERSHOCKS_B2_WEDGE_20per_CT – Synthetic model in Fig. S16 VERBRD_1_EXTENDED_WHOLE_CAT_NO_OR_AFTERSHOCKS_0p1s_NOISE_CT – Vertical resolution checkerboard tests shown in Figs. S6, S7 LOTOS_04_2018_release_2 – Full LOTOS program matlab_fuctions – functions needed to prepare above models for visualization in MATLAB. The fuction prep_lotos_mod.m is the main routine that calls the other provided functions.
