Seismic Data from the 2014-2015 Bardarbunga Volcano Intrusion, Iceland

Icelandic seismic data from a one-year deployment following the 2014 Bardarbunga dyke intrusion and Holuhraun eruption. The dataset contains 3-component seismometer recordings from September 2014 to August 2015, archived at SEIS-UK and IRIS. The data is associated with published research identifying approximately 31,000 microearthquakes from the dyke and 70,000 from the Askja-Herðubreið area.

Use Cases

• Analyzing seismic waveforms for earthquake detection and location based on the 3-component data.
• Studying temporal patterns of microearthquake swarms associated with dyke propagation.
• Modeling volcanic processes and crustal stress changes based on the identified event catalog.
• Validating and comparing seismic event locations with published supplementary catalogs.

Strengths

• Data covers a significant volcanic event with a defined one-year temporal range (Sept 2014-Aug 2015).
• Linked to published research with large, identified event catalogs (approx. 31,000 and 70,000 events).
• Data is archived at two recognized repositories (SEIS-UK and IRIS).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
