This file contains the files to reproduce the results presented in the article: Connections between arc volcanoes in Central Kamchatka and the subducting slab inferred from local earthquake seismic tomography by Bushenkova N., Koulakov I., Bergal-Kuvikas O., Shapiro N., Gordeev E.I., Chebrov D.V. , Abkadyrov I., Jakovlev A., Stupina T., Novgorodova A., Droznina S., Huang H.-H., Journal of Volcanology and Geothermal Research. This file includes: 1. The full folder with the LOTOS code for the passive-source seismic tomography (Koulakov, 2009, BSSA). 2. Folder with the dataset including arrival times of the P and S waves from local seismicity in the area of Central Kamchatka. 3. README_CEN_KAM.DOC file with the description of the workflow on how to reproduce the tomography models based on experimental and synthetic data presented in the article.
