| # BEPAD — Benchmark Earthquake Phase Association Dataset |
|
|
| [](https://pypi.org/project/bepad/) [](https://huggingface.co/datasets/ecastillot/BEPAD/tree/main/v0.2) [](https://bepad.readthedocs.io/en/latest/) [](https://github.com/ecastillot/BEPAD) |
|
|
| Thousands of phase-association problems built from **real earthquakes and real picks** of |
| [UTDQuake](https://huggingface.co/datasets/ecastillot/UTDQuake). Each **window** holds several |
| overlapping earthquakes on one seismic network, with real, generated and noise picks, and the |
| answer (earthquake) for every pick. |
|
|
|  |
|
|
| *One window (Texas network): (a) earthquakes and stations, (b) every pick at its distance from |
| its earthquake, (c) picks by type. The associator's job is to find which picks belong together.* |
|
|
| **v0.2** (current) is built from UTDQuake 1.0 (Hugging Face commit `8524c6f0`): every seismic network, named by |
| its UTDQuake code (`tx`, `CM`, `R08` ...). A station is `NET.STA` (FDSN network and station code). |
|
|
| ## Quick start |
|
|
| ```python |
| import bepad # pip install bepad |
| test = bepad.load("test", networks=["tx"], max_windows=20, labels=False) # 20 Texas test windows |
| for w in test: |
| w.picks, w.stations # the inputs of one association problem |
| report = bepad.evaluate(predictions, test) # score your associator |
| ``` |
|
|
| Without the package: |
|
|
| ```python |
| import pandas as pd |
| picks = pd.read_parquet("hf://datasets/ecastillot/BEPAD/v0.2/test/picks/network=tx.parquet") |
| ``` |
|
|
| ## Content |
|
|
| | Folder | What | |
| |---|---| |
| | `v0.2/<split>/windows` | one row per window: network, scenario (which earthquakes, how many, noise), counts, difficulty, seed | |
| | `v0.2/<split>/events` | the earthquakes of each window (origin, location, magnitude, sequence and role) | |
| | `v0.2/stations.parquet` | station coordinates; `station` = `NET.STA`, `network` = UTDQuake network | |
| | `v0.2/<split>/window_stations` | the stations available in each window (`window_id`, `station`); coordinates in `stations.parquet` | |
| | `v0.2/<split>/picks` | one row per pick: station, phase, time; labels `event_idx` (−1 noise), `pick_type` (real / generated / noise), `real`, `prob` (optional confidence for training, from detectability) | |
| | `v0.2/metadata/` | window statistics as CSV | |
| | `v0.2/label_model.json` | predicted arrivals, timing uncertainty and `prob` model | |
| | `v0.1/` | the previous release (23 scenarios, no sequences), same layout | |
| | `pool/` | the quality-controlled earthquakes and picks (for generating new training windows) | |
| | `associators/<name>/` | contributed associators (code + parameters), runnable with `bepad run` | |
| | `leaderboard/` | submitted results (scores + predictions) and the tables in `leaderboard/README.md` | |
|
|
| Per network and scenario: 600 train, 120 val and 60 test windows; 38 scenarios: which earthquakes |
| (at random, a **sequence** of aftershocks and foreshocks, or outside the network) × how many (1–20) |
| × how much noise ([Scenarios](https://bepad.readthedocs.io/en/latest/scenarios.html)). Every earthquake in a window has |
| ≥ 4 real P picks on ≥ 3 stations inside it. |
|
|
| | Split | Windows | Networks | |
| |---|---|---| |
| | train | 2,050,470 | 90 | |
| | val | 408,876 | 90 | |
| | test | 207,197 | 91 | |
|
|
| Networks with fewer than 200 earthquakes are test only (ESPOO, `R06`). |
|
|
| ## BEPAD-10 |
|
|
| The main ranking uses the **BEPAD-10 test**: the test windows of 10 networks chosen for different |
| scales, geometries and depths, from a 4 km fracking array to national networks: |
| `R05` ToC2ME, `R07` LASSO, `R01` COSEISMIQ, `nc` N. California, `tx` Texas, `JMA` Japan, |
| `CM` Colombia, `R09` N. Chile (IPOC), `ak` Alaska, `NOA` Greece. Every leaderboard entry must run them: |
|
|
| ```bash |
| bepad run associators/my-method --split test --networks core --out results/my-method |
| bepad submit results/my-method --code associators/my-method --dry-run # your row, nothing is sent |
| ``` |
|
|
| ## Leaderboard |
|
|
| See `leaderboard/README.md`: the BEPAD-10 table first (mean over its networks), then all networks, |
| then one table per network. To add a method: `bepad new`, `bepad run`, `bepad submit` — the last |
| command opens a pull request on this repository that adds only your two folders. |
|
|
| ## Benchmark rules |
|
|
| 1. Report on the `test` split. 2. Use only `picks` (without label columns) and stations as input. |
| 3. Treat each window separately. 4. Tune only on `train` / `val`; velocity models must be published or fitted on `train` / `val`. |
| 5. Run at least the BEPAD-10 networks. 6. Submit your code with your results (`bepad submit --code`): the test labels are public, so |
| entries are re-run before they are merged. |
