Data for "Ambient vibration modal analysis of natural rock towers and fins". The Hive: University of Utah Research Data Repository. --------------------- DATA & FILE OVERVIEW --------------------- Each folder contains data for a single site: time-series vibration data of each tower, a 3D model of the site, and pole-zero file(s) for removing instrument response when processing vibration data. The folders are named with the full name of each tower, and the STATIONNAME is a 3-4 letter abbreviation for the site. 1. File List A. Filename: [STATIONNAME]_[YYYYMMDD].mseed Short description: Vibration time-series data of the tower. B. Filename: [STATIONNAME].stl Short description: Photogrammetry 3D model of the landform or site used for finite element analysis. C. Filename: [instrument].vel.pz Short description: Pole-zero file corresponding to 20-s Trillium Compact broadband seismometer or 5-Hz Fairfield nodal geophone for instrument response removal. 2. Relationship between files: Files within each folder are all related to the site given by the folder name. 3. Additional related data collected that was not included in the current data package: N/A 4. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: We collected ambient vibration data of 14 towers using seismometers and nodal geophones and deployed them following methods outlined in Moore et al. (2016) and Geimer et al. (2020). We placed the instrument directly onto the landforms, usually on the top of the tower except when access was not available, and aligned them to magnetic north (save for Red Narrows). We used ground- and aerial-based photos to create 3D photogrammetry models of each tower. Moore et al. (2016): "Anthropogenic sources stimulate resonance of a natural rock bridge" doi.org/10.1002/2016GL070088 Geimer et al. (2020): "Sparse Ambient Resonance Measurements Reveal Dynamic Properties of Freestanding Rock Arches" doi.org/10.1029/2020GL087239 2. Methods for processing the data: The vibration data are submitted in the raw form, with amplitudes given in counts representing velocity. We used the pole-zero files to remove the instrument response to convert the vibration data to m/s. We created 3D models in a .stl format from photosets taken at each study site which we then used for finite element analysis. 3. Instrument- or software-specific information needed to interpret the data: We used the Python package ObsPy to process all time series data, and used IRIS's Polarization Attributes bundle to extract polarization information from the data. We generated the 3D models using Bentley Context Capture and Meshmixer, and performed finite element analysis in COMSOL Multiphysics. 4. Standards and calibration information, if appropriate: N/A 5. Environmental/experimental conditions: N/A 6. Describe any quality-assurance procedures performed on the data: N/A 7. People involved with sample collection, processing, analysis and/or submission: Riley Finnegan, Jeffrey R. Moore, Paul R. Geimer, Alex Dzubay, Erin K.
