The goal was to study seismic tremor associated with floods originating in the eastern and western Skaftár cauldrons. A third temporary array was installed during the Bárðarbunga 2014-2015 volcanic eruption near the eruption site. The aim of the array installations was to discriminate between different seismic tremor sources, namely volcanic eruptions, lava flows, hydrothermal explosions and subglacial floods (jökulhlaups). The main aim of the two arrays installed on the western margin of Vatnajökull was to study their early-warning potential through the analysis of four subglacial floods observed during the study period. The seismic vibrations associated with these floods have an emergent start, are of long duration and are referred to as tremor or high-frequency noise. Due to the lack of clear discrete onsets they cannot be located using traditional earthquake location methods. Instead clusters of seismometers (called arrays) are employed to both locate the tremor source and determine the wave type in the tremor (surface vs. body waves). The array data recorded during the Bárðarbunga eruption were used to investigate the nature of shallow, pre-eruptive, long-duration seismic tremor activity related to shallow dyke formation. The sources of the tremor were found to locate at the eruption site and under ice cauldrons which formed on the ice surface during the first weeks of the unrest. Waveform data are available from the GEOFON data centre, under network code 5L. funderName: European Union’s Seventh Programme for research, technological development and demonstration awardNumber:308377 Complete geofon@gfz.de ContactPerson missing@unknown.org pointOfContact .mseed Monitoring system GEMET - INSPIRE themes, version 1.0 publication Seismological stations Library of Congress Subject Headings publication In Situ/Laboratory Instruments > Magnetic/Motion Sensors > Seismometers GCMD Instruments publication In Situ Land-based Platforms > GEOPHYSICAL STATIONS/NETWORKS GCMD Platforms publication Geophysics SeisData publication FOS: Earth and related environmental sciences Fields of Science and Technology (FOS) publication Passive seismic SeisData publication Seismometers SeisData publication Velocity SeisData publication MiniSEED SeisData publication Ice SeisData publication Volcano SeisData publication Temporary SeisData publication Creative Commons Attribution 4.0 International Creative Commons Attribution 4.0 International 10.1038/s41467-020-15744-5 DOI Cites 10.1038/ngeo2906 DOI Cites https://geofon.gfz.de/waveform/archive/response/5L/2013_2017 URL HasMetadata eng -19 -17 64 65 Iceland 2013-01-01 574000000000 http://dx.doi.org/10.14470/0Y7568667884 WWW:LINK-1.0-http--link Landing Page Link to DOI landing page or data facility landing page if no DOI is assigned. information This metadata record was generated by an xslt transformation from a DataCite metadata record; The originator of the dataCite record should be cited in the metadataContact field of this record.
