Data and program codes to reproduce the results of seismic tomography for Okmok

This file contains the files to reproduce the results presented in the article: Kasatkina, E., Koulakov I., Grapenthin, R., Izbekov, P., Larsen, J., Al Alifi, N., and Qaysi, S.I. (2022). Multiple shallow magma sources beneath the Okmok caldera as inferred from local earthquake tomography, Journal of Geophysical Research, Solid Earth.

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 the Okmok Caldera in Aleutian Islands.

3. README_OKMOK.PDF file with the description of the workflow on how to reproduce the tomography models based on experimental and synthetic data presented in the article.
