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, code, figures, metadata, and representative high-speed videos supporting the manuscript “Why Ice-Rich Avalanches Can Be Seismically Quiet: Insights from Ice-Rock Impact Experiments” submitted to Geophysical Research Letters. The archive includes laboratory free-fall impact experiments using rock, ice, and ice–rock aggregates; processed acceleration records; Fourier and time–frequency analysis results; high-speed video documentation of representative impact and fragmentation processes; field-event comparison data for the Hochvogel 2016 and Blatten 2025 events; source–station metadata; attenuation, seismic-energy, and apparent seismic-efficiency calculations; figure source data; and processing and plotting scripts. The files are organized into separate ZIP archives for data, figures, code, documentation/metadata, and videos. A README file, file manifest, SHA256 checksums, citation file, license file, and data availability statement are included to support reuse and verification.
