The understanding of subsurface events that cannot be directly observed is dependent on the ability to relate surface-based observations processes. This particularly important for nuclear explosion monitoring, as any future clandestine tests will likely underground. We collected ground-based lidar and optical imagery using remote, very-low-altitude unmanned aerial system platforms, before after several underground high explosive experiments. For collections, we used a terrestrial scanner...
We present an analysis and interpretation of potential cliff stability at a low-level waste disposal facility Los Alamos National Laboratory, New Mexico, using morphologic fracture characteristics coupled with carbon-14 surface exposure dating. Our study is important as it directly bears on the licensing criteria for radioactive sites. find that future characteristic failures will likely not breach pits shafts over 1000-year minimum regulatory period. Further, we find, multivariate...
The detection, location, and identification of suspected underground nuclear explosions (UNEs) are global security priorities that rely on integrated analysis multiple data modalities for uncertainty reduction in event analysis. Vegetation disturbances may provide complementary signatures can confirm or build the observables produced by prompt sensing techniques such as seismic radionuclide monitoring networks. For instance, emergence non-native species an area be indicative anthropogenic...
Optical remote sensing has become a valuable tool in many application spaces because it can be unobtrusive, search large areas efficiently, and is increasingly accessible through commercially available products systems. In the space of chemical, biological, radiological, nuclear, explosives (CBRNE) sensing, optical an especially enables data to collected from safe standoff distance. Data results collections combined with other methods offer integrated understanding nature activities area...
Abstract Vegetation has the potential to respond underground nuclear explosions, yet these links have not been fully explored. Given lack of previously described signatures, changes in vegetation are possibly subtle. The integration multiple different data streams is potentially a useful approach improve signal detection. Here, we investigate whether semi‐arid growth patterns responded eight legacy tests at Nevada National Security Site southern Nevada, USA. We tested for spatial and...
