Each study site had three broadbands from September 2023 to June 2025. In addition, were installed and recording: September – November 2023: six geophones on each site; April – August 2024: four geophones at Njárgavárri and ten at Indre Nordneset. The geophones were installed locally around the rockslides while the broadbands were installed one to a few kilometers from the rockslides (except for one of them directly at Indre Nordneset). The geophones in Njárgavárri were first installed as two triangular antennas of four stations each (three in triangle and one in the middle) and were then replaced by a small aperture array around the most active part of the unstable slope. The goal was to record all activities: rock falls, cracking and creeping movements. In Indre Nordneset, the geophone stations were placed in a small aperture array all around the main scarp and surface of failure to record the cracking activity. The geophones are of type 3-D Geophone PE-6/B with DATA-CUBE3 (built-in GPS). The broadbands are of type STS-2.5 with EDR-10 digitizers. Sampling frequency was 400 Hz for geophone stations, 200 Hz broadbands. Gain was at 16 (15.258789 nV/count) for the geophone stations, set on high (100 nV/bit) for the broadband stations. Waveform data is available from the GEOFON data centre, under network code 8I. funderName:GFZ Helmholtz Centre for Geosciences funderIdentifier:https://ror.org/04z8jg394; IDType:ROR awardNumber:GIPP202305 funderName:Community Research and Development Information Service funderIdentifier:https://ror.org/02nc61e46; IDType:ROR awardNumber:EnvSeis 101073148 Complete geofon@gfz.de ContactPerson missing@unknown.org pointOfContact .mseed rockslides rock fall creeping landslides EARTH SCIENCE > SOLID EARTH > TECTONICS > EARTHQUAKES NASA/GCMD Earth Science Keywords publication EARTH SCIENCE > SOLID EARTH > TECTONICS > VOLCANIC ACTIVITY NASA/GCMD Earth Science Keywords publication In Situ/Laboratory Instruments > Magnetic/Motion Sensors > Seismometers GCMD Instruments publication In Situ Land-based Platforms > GEOPHYSICAL STATIONS/NETWORKS GCMD Platforms publication In Situ Land-based Platforms > GEOPHYSICAL STATIONS/NETWORKS > SEISMOLOGICAL STATIONS 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 GIPP SeisData publication MESI SeisData publication Temporary SeisData publication Polar/ice SeisData publication embargoed access embargoed access https://geofon.gfz.de/waveform/archive/response/8I/2023_2025 URL HasMetadata https://www.ngu.no/publikasjon/faren-fjellskred-fra-nordnesfjellet-i-lyngenfjorden-troms URL IsDescribedBy eng 20.3 21 69.4 69.6 Norway 2023-04-25 495000000000 http://dx.doi.org/10.14470/3V875927 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.
