Pacific Northwest Curated Seismic Dataset

A curated dataset for a wide range of sources from the Pacific Northwest

Overview

Each dataset is made by two files: waveform (in HDF5 format) and metadata (in CSV format). All follow the structure of seisbench format. See here to learn more about the file structure.

Datasets

We are hosting two copies of the dataset: one on Google Drive, another on UW-ESS server. All datasets are also available through SeisBench.

• EN (accelerometer)

  • waveform (2.1 GB): [GDrive] | [UW-ESS]
  • metadata (1.7 MB): [GDrive] | [UW-ESS]

2. Noise Waveform (EH, BH, and HH)

• waveform (~18 GB): [GDrive] | [UW-ESS]

• metadata (126 KB): [GDrive] | [UW-ESS]

5. ML-enhanced catalog

• CSV (~93 MB): [GDrive]

Access

Quick tour to the dataset

Here are several ways to use the PNW dataset.

1. Jupyter Notebook

A jupyter notebook is available to load and plot PNW dataset at here. Download and run it on a local machine to enable the interactive plotting (e.g., zoom in/out for checking the picks).

1. A notebook is available here on accessing the dataset with SeisBench APIs.

2. Google Colab

If you are more familiar with Google Colab, go to the link above. Note that interactive plotting is not available on Colab.

Demo sets

1. A micro version of the dataset, which contains 10 earthquake streams, 10 explosion streams, 10 sonic boom streams, 10 thunder streams, and 10 surface event streams. See data/microPNW.

2. A mini version of the dataset, which contains 500 earthquake streams, 500 explosion streams, 500 surface event streams, 126 sonic boom streams, and 94 thunder quake streams.

   • waveform (640 MB): [Google Drive] | [UW-ESS]
   • metadata (424 KB): [Google Drive] | [UW-ESS]

3. A meso version with 10% of the full ComCat dataset (only earthquake + explosion).

   • waveform (6.3 GB): [Google Drive] | [UW-ESS]
   • metadata (4.7 MB): [Google Drive] | [UW-ESS]

Known issues

• [August 2023] Very few events (~15) in the ComCat dataset may have inconsistent event_type_pnsn_label and event_type. This issue comes from the outdated ComCat event metadata. Please prioritize PNSN label when such inconsistent occurs.
• [June 2025] The trace_start_time field in the exotic metadata was delayed by 50 seconds. The metadata has now been corrected for all affected files.
