Survey of the fluxsite in Muntetschinig, South Tyrol (IT), September 2015

"The study is situated at an elevation of around 1550 m a.s.l. on a southwest facing slope of the Venosta Valley in northern Italy. Average (19802010) annual temperature amounts to 6.5 °C, annual precipitation to 550 mm. The study site is lightly grazed by cattle and sheep in spring and fall. During summer, plant growth is limited by low soil water contents. Vegetation is hence dominated by drought and grazing adapted grasses (Festuca valesiaca agg.), herbs (Hieracium pilosella agg.) and shrubs (Juniperus communis agg.). Soils are shallow leptosols and characterised by high sand and silt contents." (Wohlfahrt et al. 2016).

Survey of Warnimont Bluff, Wisconsin, December 2019

High lake levels are reducing beach area along the Lake Michigan coastline and allowing wave action to erode the bases of coastal bluffs at the highest rate of the past 30 years. Sediment budget calculations have shown that bluff erosion is the dominant source of sand and gravel-sized particles that are mobilized into beaches and the nearshore system. Researchers have found that the leading cause of bluff erosion is shallow to intermediate depth translational landslides. Therefore, estimating lake sediment budgets depends on an understanding of the mechanisms that lead to landslide failure. This study will provide a comprehensive analysis of bluff stability for bluffs affected by landslide failure coupled with an analysis of bluff composition to determine the composition of sediment contributions of coastal bluffs to the southeast Lake Michigan sediment budget.

This dataset is part of a series of repeat surveys documenting temporal changes to a ~100 m long extent of unconsolidated coastal bluffs on Lake Michigan.

High Resolution Topography along the Lost River Valley, Idaho 2019

The goal of this project was to systematically measure fault vertical separation to produce the most comprehensive throw dataset along the Lost River Fault (which was activated during the 1983 Borah Peak earthquake), as well as in prehistoric earthquakes.   A database was created to better understand coseismic faulting processes, refine scaling laws, and further develop global probabilistic hazard calculations. (Bello et al., in prep.)   Over 10,000 photographs were acquired using a DJI Phantom 4 Pro and a Phantom 4 Unmanned Aerial Vehicles (UAVs) that flew at ~50-110 meters above ground. In total, ~20 km along the strike of the Lost River Fault was measured at 13 different areas with an average width (fault trace normal) of ~417 m.

Lost River Fault Zone Near Borah Peak, Idaho

The contribution comprises high-resolution topography and orthomosaics of part of the Lost River fault zone (LFRZ), Idaho, USA. The data set covers the northern ~16 km of the surface-rupture that occurred on the LRFZ in the Mw 6.9 1983 Borah Peak Earthquake. Point clouds and digital surface models (DSMs), were generated from low-altitude aerial photographs using Structure-from-Motion and multi-view stereo processing (SfM).  The LRFZ is a major, range-bounding, west-dipping normal fault in the northern Basin and Range province. The Mw 6.9 1983 Borah Peak earthquake occurred on it and created surface rupture along the southern portion of the Warm Spring section and the entire Thousand Springs section of the fault (Crone et al., 1987; DuRoss et al., in press).  The Warm Spring and Thousand Springs sections are separated by the Willow Creek Hills, which form a structural boundary. We used unoccupied aerial systems (UAS) and a tethered "helikite" balloon to acquire aerial photographs, which were combined with ground control georeferencing to create two point clouds that model the topography at high resolution ( DSMs were generated from the point clouds, and orthomosaics of each area were made from the aerial photographs. The primary motivation for acquisition of the data set was study of the surface offset across the Willow Creek Hills structural boundary from the 1983 earthquake and prehistoric surface-rupturing events (DuRoss et al., in press).

Photogrammetric model of the Tecolote Volcano, Sonora, Mexico

Topographic model of the Tecolote Volcano edifice and portions of adjacent lava flows (Pinacate Volcanic Field, Sonora, Mexico) was produced from 2,024 sUAS derived aerial photographs using the structure from motion method. Model shows numerous volcanic features including the main breached edifice, rafted edifice material on lava flow, several well preserved conical vents, and many bombs in the proximal setting. In addition, numerous fractures are evident cutting the main edifice without much tephra cover, indicating their late stage development. Work in progress by Zawacki, et al. is reconstructing the last eruption from Tecolote and suggests an eruption age of 20-40ka. Data were collected by a team from ASU and Oklahoma State University composed of: Scott, C.P., Scott, T., Lao-Davila, D.A., Clarke, A.B., Arrowsmith, J.R., and Lynch, D.

High Resolution Topography of House Range Fault, Utah

The House Range fault data set comprises high-resolution topography and an orthomosaic of part of the House Range fault (HRF) and shorelines of Late Pleistocene Lake Bonneville that it cuts in the Sevier Desert, Eastern Basin and Range Province, Utah, USA. The data set covers ~4.5 km of the HRF scarp, in the central portion of the HRF. The site was chosen for the well-developed and preserved scarp, shorelines, and cross-cutting relationships in the area. UAS  derived low-altitude aerial photographs and dGNSS  measured ground control points were processed with Structure-from-Motion and multi-view stereo software (SfM) to generate a point cloud, digital surface model (DSM), and orthomosaic, of the area.  The House Range fault (HRF) is a range-bounding, west-dipping normal fault in the western Sevier Desert, within the eastern Basin and Range province, Utah, USA. There is up to 1600 m of vertical relief across the fault, and it displays characteristics typical of tectonically  driven extensional faulting, in contrast to extension that is associated with volcanism in the eastern Sevier Desert (Stahl and Niemi, 2017; Stahl et al., in review).
