Results of the ambient noise tomography based on the seismic data recorded in Central and South Kamchatka in 2012-2024

This file contains the results of the ambient noise tomography of Central and South Kamchatka presented in: Belovezhets N., Berezhnev Y., Abramenkov S., Abkadyrov I., Yakovlev A., Chebrov D., Chemarev A., Ponasenko S., Koulakov I. (2026). Ambient noise tomography of 12 years of seismic data reveals magmatic systems and fault structures beneath Central and South Kamchatka. Submitted to Journal of Volcanology and Geothermal Research. The dataset includes the following files: Ambient noise cross-correlation functions computed for continious seismic data from temporary and permanent seismic stations operating in 2012-2024 in Central and South Kamchatka: stack_cc_CC_st1_st2.dat files which are linearly stacked component-component (vetrical, radial or transverse) cross-correlation functions between seismic station 1 and seismic station 2 with corresponding names st1 and st2. The correlation time is from -400 s to 400 s with a sampling frequency of 1 Hz. Rayleigh and Love waves phase and group velocity dispersion curves: Disp_Central_Kamchatka_CC_type_final.dat files, with are type (phase or group) velocity dispersion curves extructed from component-component (vetrical, radial or transverse) cross-correlation functions for all available periods. Resulting velocity model with README-file: average_3D_model.nc and average_3D_model_readme.txt. Sensitivity distribution: 3dsenstivity.npy.
