SeismoBench v1

Synthetic seismogram film in the style of WWSSN film chips, with exact ground truth. It scores line tracers where an earthquake trace swings across its neighbours. SeismoBench is part of SeismoRescue, built during the Meta Global AI Developer Hackathon (October 26 – November 4, 2026).

This repository mirrors the GitHub release bench-v1. The files are the same, with the same sha256 (SHA256SUMS).

The truth is public, so scores rest on trust. There are no outside participants so far; every row on the leaderboard is one of our own baselines.

Files

File	Images	Contents
holdout7.tar	95	Main table: 19 records, 10 earthquakes (M7.5–8.8)
holdout6.tar	90	18 records, 10 other earthquakes
holdout4.tar	100	Development set: 20 records, 10 other earthquakes
baselines.tar		Our baseline submissions for the three splits (LEADERBOARD.md)

The same earthquake never appears in two splits. Each record has three kinds of file:

• film/heli_g<gain>.png: the film at five amplitudes (1×, 2×, 4×, 6×, 8×)
• film/gt_g<gain>.npz, with three arrays:
  • pen: the pen's row per line and column
  • sig: the signal without the pen's minute marks
  • mark: where the minute marks are
• film/meta.json: spacing, margin_x, margin_y, n_lines, gains, active_line (the line with the earthquake), event (the earthquake's time and magnitude, the distance and the station) and the renderer's settings

Use

The fetcher and the scorer are in the GitHub repository. They need NumPy and Python 3.12, 3.11.4+ or 3.10.12+ (see bench/README.md). SEISMOBENCH_URL points the fetcher at this mirror, and the hashes are checked either way.

git clone https://github.com/smpark00/seismorescue && cd seismorescue
SEISMOBENCH_URL=https://huggingface.co/datasets/seungminpark/seismobench/resolve/main python -I bench/fetch_bench.py holdout7 baselines
python -I bench/score.py bench_data/holdout7 bench_data/baselines/holdout7/sam3_both_directions --name sam3_both_directions

The submission format and the score definitions are in bench/README.md and at the top of bench/score.py.

Source records and licence

The films are rendered from public broadband records of the Global Seismograph Network, networks IU (doi:10.7914/SN/IU) and II (doi:10.7914/SN/II), downloaded through the EarthScope (formerly IRIS) FDSN web services. We found no licence declared by either network: DataCite and the FDSN network pages list none (checked 2026-11-03). EarthScope states that its facility distributes data without a declared licence under CC BY 4.0 (registry entry).

• The film images and truth files are our renderings of those records, released under the MIT licence.
• The CC BY 4.0 attribution still applies. If you use or share the films, cite the two networks above and say that the films were rendered from their records. The same EarthScope statement asks users to cite the facility as well (how to cite).
• The SAM 3 baseline paths in baselines.tar are outputs of a model under Meta's SAM License.
