Seismic Data from the 2014-2015 Bardarbunga Volcano Intrusion and Eruption

Over 100,000 microearthquake events were recorded by 3-component seismometers deployed for one year following the 2014 Bardarbunga dyke intrusion and subsequent Holuhraun eruption. The dataset contains raw seismic waveforms in miniseed format, archived at SEIS-UK and IRIS, with event locations published in multiple peer-reviewed studies. Data collection was funded by NERC grant NE/M017427/1 and managed by the British Geological Survey.

Use Cases

• Analyzing strike-slip faulting patterns during dyke intrusion based on the published event catalog.
• Studying deep crustal melt plumbing systems using the high-resolution seismic waveforms.
• Modeling volcanic eruption precursors and processes based on the year-long seismic monitoring.
• Comparing seismic activity between the Bardarbunga and Askja volcanic systems as referenced in the related studies.

Strengths

• Contains over 100,000 located seismic events (approx. 31,000 from Bardarbunga, approx. 70,000 from Askja-Herðubreið).
• Data is archived at two recognized repositories: SEIS-UK and IRIS.
• Event locations are published and publicly available in the supplementary information of peer-reviewed papers.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the raw waveform data is unknown, which may limit suitability assessment.
