    Seismological Characterization of the Geothermal Field Laboratory Rhineland (2022)
    GFZ Data Services
    Details
    Publication Date: 2023-02-08
    Description: Abstract
    Description: – A temporary seismic network consisting of 48 long-term and 15 short-term stations was deployed from June 2021 to June 2022. The network comprises 27 broadband stations and 20 short period geophones from the Ruhr-University Bochum, the Geophysical Instrument Pool Potsdam (GIPP) and the RWTH Aachen. The inter-station spacing of the longer-term network is about 2 km and the total extent of the network is about 20 km. The densely populated area and vicinity of active pit mining demanded a balance between dense station placement and avoidance of anthropogenic noise sources. The network serves as a pre-study for the installment of a field laboratory in Eschweiler-Weisweiler, Germany. Details can be found in the accompanying data publication (Finger et al., in preparation). This project has been subsidized through the Cofund GEOTHERMICA, which is supported by the European Union’s HORIZON 2020 programme for research, technological development and demonstration under grant agreement No 731117. Furthermore, this study was supported by the Interreg North-West Europe (Interreg NWE) Programme through the Roll-out of Deep Geothermal Energy in North-West Europe (DGE-ROLLOUT) Project (http://www.nweurope.eu/DGE-Rollout), NWE 892. The Interreg NWE Programme is part of the European Cohesion Policy and is financed by the European Regional Development Fund (ERDF). Waveform data are available from the GEOFON data centre, under network code ZB. Data from some stations are embargoed until Januar 2026 but might be available on request.

    FoMapS: Seismic investigation of the Fogo magmatic plumbing system, Cape Verde, using multi-array techniques (2020)
    GFZ Data Services
    Details
    Publication Date: 2023-02-08
    Description: Abstract
    Description: Volcanic eruptions are regularly observed on the island of Fogo, Cape Verde, with an average re-occurrence interval of ca. 20 years. However, the structure and extent of the related volcanic plumbing system are not well understood. Previous studies have investigated earthquakes related to magmatic processes connected with the Fogo volcano using conventional network configurations. Seismicity has been reported to occur mainly southwest of the island of Brava while a more recent study reports on activity focussed between Brava and Fogo. Multi-array seismology has the potential to significantly reduce the localization errors of seismic events in particular for those outside a station network and to lower the detection threshold. The subject of this study is the investigation of the local volcano-related seismicity applying multi-array methods which is a unique task amongst the research activities at German universities. The scientific aims are (a) to precisely map local events to constrain the structure of and the dynamic processes within the volcanic plumbing system, (b) to image the magma source region below the Fogo volcano using reflected and backscattered waves, and (c) to localize low-frequency volcanic tremor events. Waveform data are available from the GEOFON data centre, under network code 9J, and are embargoed until February 2022.

    META-WT (2023)
    GFZ Data Services
    Details
    Publication Date: 2023-04-25
    Description: Abstract
    Description: The META-WT project was designed to perform a 4-weeks seismic experiment in Germany with a dense seismic array of ~400 three-component geophones that covered (1) a 2.5km x 2.5km wind farm area in Brandenburg, Germany, with almost 200 wind turbines (WTs) and a well-studied subsurface structure and (2) a 20-km long radial line from the center of the wind farm with one geophone every half-kilometer. The objective was to capture the spatio-temporal seismic wave-field signature of the wind farm from continuous recordings of ambient noise. Due to the dense interstation distance and proposed geometry the experiment allowed for analyzing both small-scale wave field characteristics at an unprecedented spatial resolution and the longer distance radiation pattern of the wind farm. Waveform data is available from the GEOFON data centre, under network code XF, and is embargoed until Jan 2025.

    Publication Date: 2023-05-11
    Description: Abstract
    Description: The Illgraben is a 10 km² steep side valley located in Switzerland. This active debris flow catchment supplies 5-15% of the total sediment load of the Rhône River upstream of Lake Geneva. The 30-80° steep catchment slopes host frequent rock falls and slides. From 2012 to 2014, a network of up to ten Nanometrics Trillium Compact 120s broadband seismometers, sampled by Digos DataCube³ext loggers at 200 Hz (and later by centaur), was deployed in and around the catchment to monitor distributed geomorphic activity. Waveform data is available from the GEOFON data centre, under network code 9J, and is fully open.

    SEAMSTRESS: DEPAS ocean-bottom seismometer operations on Vestnesa Ridge in 2020-2021 (2023)
    GFZ Data Services
    Details
    Publication Date: 2023-05-22
    Description: Abstract
    Description: “This ocean-bottom seismometer deployment is part of the SEAMSTRESS project examining tectonic stress effects on Arctic methane seepage. The project is led by PI Andreia Plaza-Faverola at the Centre for Arctic Gas Hydrates, University of Tromsö, Norway. A total of 10 ocean bottom seismometers (OBS) were deployed on Vestnesa Ridge, a sediment drift body just north Knipovich Ridge at its intersection with the Molloy Transform fault (cruise CAGE-20-5). The aim of the experiment was to look for stress release along faults that control seepage sites on Vestnesa Ridge. The network consisted of 8 Lobster type broadband OBS from the German Instrument Pool for Amphibian Seismology (DEPAS) and 2 3C geophones provided by the University of Tromsö. Instruments were free-fall deployed and spaced by about 10 km. They recorded continuously at 100 Hz for 11 months between August 2020 and July 2021.Short, intersecting refraction profiles were shot across all OBS stations, such that OBS positions at the seafloor could be determined within 10 m (cruise CAGE-21-3). Clock drift in this experiment was nonlinear and skew values were only obtained for 6 of the stations. Skew-corrected station VSN01 served as reference station to obtain the clock drift of all other stations using noise cross-correlation and subsequently correct also for the thus determined nonlinearity of time drift. Waveform data are available from the GEOFON data centre, under network code Y9 and are embargoed until July 2025.

    Project LOKI: DEPAS ocean-bottom seismometer operations at Loki's Castle vent field in 2019-2020 (2023)
    GFZ Data Services
    Details
    Publication Date: 2023-05-22
    Description: Abstract
    Description: This ocean-bottom seismometer deployment is part of the LoCHnESs (Loki Castle Hydrothermal iN-situ Experiements and Surveys) project examining hydrothermal fluid circulation at Loki's Castle vent field. The project is led by PI Thibaut Barreyre at the Centre for Deep Sea Research, Department of Earth Science, University of Bergen, Norway. A total of 8 ocean bottom seismometers (OBS) were deployed near Loki's Castle vent field at the Mohns-Knipovich Ridge bend, Norwegian-Greenland Sea. The aim of the experiment was to monitor seismicity related to changes in the hydrothermal circulation system and to reveal interaction between an active detachment fault and the axial volcanic ridge hosting the vent site. The network consisted of 8 DEPAS Lobster type broadband OBS from the German Instrument Pool for Amphibian Seismology (DEPAS). Instruments were free-fall deployed and spaced by about 5-8 km. They recorded continuously at 100 Hz for 12 months between July 2019 and July 2020. Two instruments (LOK01 and LOK06) could only be deployed one month later and recorded at 250 Hz. OBS positions at the seafloor were determined by interpolation at 2/3 of the distance between the deployment and recovery position at the seafloor. Position accuracy is estimated to be about 100 m. Skew values were obtained for all stations and reached values of up to 24 s. Clock drift in this experiment was nonlinear. Skew-corrected station LOK02 served as reference station to obtain the clock drift of all other stations using noise cross-correlation and subsequently correct also for the thus determined nonlinearity of time drift. Waveform data are available from the GEOFON data centre, under network code 8M and are embargoed until July 2025.

    Catalog of start and end times of lava fountaining episodes from 2 May to 14 June 2021 during the Fagradalsfjall eruption (2022)
    GFZ Data Services
    Details
    Publication Date: 2023-06-12
    Description: Abstract
    Description: The Fagradalsfjall eruption from 19 March to 18 September 2021 featured lava fountaining episodes from 2 May to 14 June. These episodes were recorded as tremor pulses on our broadband seismic station NUPH (Nanometrics Trillium Compact 120s) at 5.5 km southeast of the active vent. We used the seismic data bandpass filtered between 1 and 4 Hz to mark the start and end of 7058 tremor pulses. The catalog hence comprises 14116 markers, that are statistically further evaluated in Eibl et al. (in review). From 2 May to 14 June, several changes in pulse duration and repose time were found and used to subdivide this time interval into 6 periods with characteristic pulse pattern. We find exponentially decreasing pulse durations, coexisting short and long pulses and stable pulse durations superimposed by gradually increasing or suddenly decreasing repose times. We discuss the findings in the context of an evolving shallow-conduit container, the crater geometries, partial collapses from the crater rim and the amount of accumulating outgassed magma in Eibl et al. (in review). This data publications releases the catalog of 14116 tremor pulses /lava fountaining episodes.
    Description: Methods
    Description: We installed a Trillium Compact 120 s seismometer (Nanometrics) as station NUPH (9F seismic network) at the southeast corner of Núpshlídarháls 5.5 km southeast of the eruptive site in Geldingadalir, Iceland. The instrument stood on a concrete base slab shielded from wind and rain using a bucket partly covered by rocks. The instrument was powered using batteries from 16 March, solar panels from 24 March and a wind generator at 10 m distance from 6 April 2021. Data were sampled at 200 Hz, they were stored on a Datacube and regularly downloaded. We used a compass to align the instrument to geographic north.

    Temporary DAS Deployment associated with the DEEPEN project in the Hengill region, Iceland (DEEPEN) (2023)
    GFZ Data Services
    Details
    Publication Date: 2023-07-12
    Description: Abstract
    Description: From June to August 2021 the DEEPEN project deployed a dense seismic nodal network across the Hengill geothermal area in southwest Iceland to image and characterize faults and high-temperature zones at high resolution. The nodal network comprised 498 geophone nodes spread across the northern Nesjavellir and southern Hverahlíð geothermal fields and was complemented by an existing permanent and temporary backbone seismic network of a total of 44 short-period and broadband stations. In addition, two fiber optic telecommunication cables near the Nesjavellir geothermal power plant were interrogated with commercial DAS-interrogators. During the time of deployment, a vibroseis survey took place around the Nesjavellir power plant. The here published dataset contains a subset of the downsampled DAS-recordings from the eastern fiber optic array. To save storage space, only every fourth trace was made available. The original data were downsampled from 1000Hz to 250 Hz using the das-convert tool (https://doi.org/10.5880/GFZ.2.1.2021.005). Further traces or the original data can be obtained upon request. Waveform data are available from the GEOFON data centre, under network code ZH.

    Seismicity catalogue for the Eastern Alps (Swath-D) (2023)
    GFZ Data Services
    Details
    Publication Date: 2023-09-01
    Description: Abstract
    Description: We present a new, consistently processed seismicity catalogue for the Eastern and Southern Alps, based on the temporary dense Swath-D monitoring network. The final catalogue includes 6,053 earthquakes for the time period 2017-2019 and has a magnitude of completeness of −1.0ML. The smallest detected and located events have a magnitude of −1.7ML. Aimed at the low to moderate seismicity in the study region, we generated a multi-level, mostly automatic workflow which combines a priori information from local catalogues and waveform-based event detection, subsequent efficient GPU-based event search by template matching, P & S arrival time pick refinement and location in a regional 3-D velocity model. The resulting seismicity distribution generally confirms the previously identified main seismically active domains, but provides increased resolution of the fault activity at depth. In particular, the high number of small events additionally detected by the template search contributes to a more dense catalogue, providing an important basis for future geological and tectonic studies in this complex part of the Alpine orogen.
