- Description:
- We deployed a Nanometrics Trillium Compact 20-s, three-component broadband seismometer on the summit of Devils Tower between October 12-13, 2024. The instrument was hauled and carried to the summit by a team of climbers under an approved permit from the National Park Service. The seismometer (labelled station D) was located on the northern portion of the tower summit. It was placed on bare bedrock, with a dab of adhesive putty under each foot to aid coupling, leveled and oriented north, and then covered to prevent wind buffeting. The seismometer was paired with a 24-bit Nanometrics Centaur datalogger recording continuous data at 100 Hz. Two additional identical seismometer setups were also deployed: station C on bedrock near the base of the tower’s south wall, and station A on a large flat boulder embedded in colluvium ~200 m south of the tower. The various instruments had different run times: station D on top of the tower ran the longest for 21 hours from afternoon to late morning, while the overlapping duration of the three sensors was 19 hours (10/12 20:00 to 10/13 15:00 UTC).

- Description:
- Each saguaro was temporarily instrumented with a Raspberry Shake 3D seismometer. The Raspberry Shake 3D is a low-cost and light-weight three-component seismometer that has been extensively benchmarked against other instruments (e.g., Arosio et al., 2023). It records three mutually-orthogonal components of motion (two horizontal and one vertical) using 4.5 Hz geophones with range electronically extended down to at least 0.5 Hz, at a sampling rate of 100 Hz, and internal data storage. I devised a custom mounting bracket for this study consisting of a 3D-printed platform that could be strapped to a saguaro stem and leveled about 1.5 m above ground level. The mounting height was arbitrary, being as high as feasible without requiring a ladder, and the method ensured that no damage was caused to the cactus. A small portable battery provided power.

- Description:
- This dataset accompanies the research article entitled, "Ground Motion Amplification at Natural Rock Arches in the Colorado Plateau ," where we analyzed 13 sandstone arches in Utah, computing site-to-reference spectral amplitude ratios from continuous ambient seismic data and comparing these to spectral ratios during earthquakes and teleseismic activity. Included in this dataset are the arch vibration data.
