Multi-Modal DAG-4 Dataset

This dataset include seismic, infrasound, and electromagnetic sensor records collected over a two-week period, June 15 to June 30, 2019 within 255 km of a 10t buried chemical explosions called DAG-4. A catalog of 485 seismic, seismo-acoustic, and infrasound-only events was manually built by an analyst reviewing the seismic and infrasound waveforms included in this dataset. We deliver these waveforms in NNSA KbCore CSS .w format (i4) with corresponding metadata tables. We intend for this dataset to provide a valuable, benchmark resource to develop signal processing algorithms and explosion monitoring methods.
