Data and code for "Nonlinear Fragmentation and Ice Content Explain Weak Seismic Radiation from Rock–Ice Avalanches: Laboratory and Field Evidence"

This Zenodo record archives the data, analysis code, figure-source files, metadata, and representative high-speed videos supporting the manuscript “Nonlinear Fragmentation and Ice Content Explain Weak Seismic Radiation from Rock–Ice Avalanches: Laboratory and Field Evidence.” The archive includes laboratory free-fall impact experiments using pure rock, pure ice, and mixed ice–rock aggregates; processed impact-force and acceleration measurements; spectral and time–frequency analyses; fragmentation and seismic-efficiency metrics; and representative high-speed videos of impact, rebound, and fragmentation. It also contains field-event data for the 2025 Blatten rock–ice avalanche and the 2016 Hochvogel rock-slope failures, including source and station metadata, attenuation analyses, radiated seismic-energy and apparent seismic-efficiency estimates, and laboratory-to-field comparison data. Figure-source workbooks and Python scripts are provided for the main quantitative figures and supplementary field analyses. The archive is organized into three packages: data and code.zip, containing curated laboratory and field datasets, plotting workbooks, processing and figure-generation scripts, and documentation; Figure.zip, containing the manuscript and supplementary figures; and videos.zip, containing representative experimental videos. README documentation and source-trace information are included to facilitate reproducibility, interpretation, and reuse.
