Monitoring Magmatism and Intrusion from the Bardabunga Volcano, Iceland (NERC grant NE/M017427/1)
The dataset contains 3-component seismic data from seismometers deployed for one year Sept 204-August 2015 following the dyke intrusion from Bardarbunga which led to a 6 month long eruption at Holuhraun. The data is in miniseed format, archived at SEIS-UK and IRIS. The locations of all the microearthquakes we have identified from this data are published in Supplementary Information of Ágústsdóttir et al. (2016) [approx. 31,000 events from the Bardarbunga dyke], in Greenfield et al. [approx. 70,000 events from the Askja-Herðubreið area], and in Hudson et al. (2017), where they are publicly available for download. Ágústsdóttir, T., Woods, J., Greenfield, T., Green, R. G., White, R. S., Winder, T., Brandsdóttir, B., Steinthórsson, S. & Soosalu, H. (2016).

The seismic data was recorded continuously at 100 sps with continuous GPS. Almost permanent daylight in summer (this is near the Arctic circle), together with the use of large truck batteries (typically 3 x 115 Amp-hrs) and multiple solar panels on each site (typically 80 watts), provided sufficient power supply through both the summer and winter months to keep the seismometers operating continuously. The prevalence of basaltic rocks means that compasses are unreliable indicators of true north, so we used GPS to orient the seismometers. Data has been converted from Guralp GCF format to miniseed.
