Description This repository contains codes and supporting datasets (earthquake catalogs, cable geometry, P and S-picks, and cross-correlation tables) for Bocchini et al. (in review in Earth System Science Data (ESSD)) The same files shared in this repository are also available in https://gitlab.ruhr-uni-bochum.de/bocchgxw/das-kefalonia The paper presents a new earthquake catalog constructed using DAS (Distributed Acoustic Sensing) and seismic station data, and provides two-week open-access DAS waveforms used to build the earthquake catalog. Note: Continuous DAS waveforms are uploaded separately. Link to DAS waveform data repository: > Bocchini, G. M., Roth, M., Harrington, R.M. (2025). Earthquake Catalog and Continuous Waveforms From a Two-week Distributed Acoustic Sensing Experiment On Kefalonia Island, Greece. https://doi.org/10.60517/cv43p1601 The catalog and the data analysis spans from 23:00 h on 1st August 2024 to 23:00 h on 15th August 2024.
