Cross-correlation functions for "Imaging magma pathway beneath Kirishima volcanoes by ambient noise tomography"

The cross-correlation functions used in Nagaoka et al. 2025. We used three-component seismograms recorded between April 1st, 2011 and December 31th, 2013 at 37 stations (21 broadband sensors and 16 short-period sensors with a natural frequency of 1 Hz). These seismic stations were deployed by Earthquake Research Institute, the University of Tokyo, Aso Volcanological Laboratory, Kyoto University, National Research Institute for Earth Science and Disaster Resilience, and Japan Meteorological Agency. The data can be found in the zip file.
