Basin effects from 3D simulated ground motions in the Greater Los Angeles region for use in seismic-hazard analyses Basin effects from 3D simulated ground motions in the Greater Los Angeles region for use in seismic-hazard analyses
We develop basin-depth-scaling models (i.e. “basin terms”) from the long-period (T≥2s) simulated ground motions of the Southern California Earthquake Center (SCEC) CyberShake project for use in seismic hazard analyses at sites within the sedimentary basins of southern California. Basin terms use the Next Generation Attenuation (NGA)-West-2 ground-motion models (GMMs) as reference...

Living with wildfire in Stemilt Basin, Chelan County, Washington: 2022 Data report Living with wildfire in Stemilt Basin, Chelan County, Washington: 2022 Data report
Homeowner wildfire risk mitigation and preparedness are important components of community wildfire readiness. This report presents data collected via rapid wildfire risk assessments to describe the parcel-level wildfire risk of properties within the Stemilt basin, Chelan County, Washington study area. The report also describes household survey data collected from homeowners in the study...

A video monitoring and computational system for estimating migratory juvenile fish abundance in river systems A video monitoring and computational system for estimating migratory juvenile fish abundance in river systems
Diadromous fishes migrate between marine and fresh waters for reproduction. For anadromous species, which spawn in freshwater, improved access to freshwater spawning and nursery habitats and ability of juveniles to emigrate to the ocean may support population recovery. Despite the potentially enormous influence of early life stage survival on adult population size, managers and...

Effects of insecticide spray drift on arthropod prey resources of birds in grasslands in Minnesota Effects of insecticide spray drift on arthropod prey resources of birds in grasslands in Minnesota
Soybean aphid (Aphis glycines) insecticides are used throughout the Upper Midwest and Great Plains regions of North America, including the farmland region of Minnesota, USA, to combat insect pests. These broad-spectrum, foliar spray insecticides have the potential to drift beyond target fields into nearby grassland cover where birds and other insectivores forage. Arthropods serve...

Land use and dog park associations with Escherichia coli in the Chattahoochee River National Recreation Area watershed Land use and dog park associations with Escherichia coli in the Chattahoochee River National Recreation Area watershed
A recent study in the Chattahoochee River National Recreation Area (CHAT) indicated that dogs were a primary source of fecal contamination in the Chattahoochee River and that at least some of the contamination in the river was coming from locations outside of CHAT. The study herein sought to determine if dog parks in the CHAT watershed were sources of dog fecal contamination in streams...

Abundance of Long-billed Curlews on military lands in the Columbia Basin Abundance of Long-billed Curlews on military lands in the Columbia Basin
Long-billed Curlews (Numenius americanus) are declining throughout North America, and the loss of grassland breeding habitat is one of the primary threats to the species. Intermountain West, in particular, has been identified as the most important region in North America for breeding curlews. Nevertheless, the density and abundance of Long-billed Curlews in this region is not well...

Revisiting geophysical interpretations of the Midcontinent Rift below Lake Superior— Insights from GLIMPCE seismic-reflection line C Revisiting geophysical interpretations of the Midcontinent Rift below Lake Superior— Insights from GLIMPCE seismic-reflection line C
The 1.1 Ga Midcontinent Rift System (MRS) has been investigated in the Lake Superior region for more than a century. The most influential geophysical data for modern paradigms has come from seismic-reflection profiles collected by the Great Lakes International Multidisciplinary Program on Crustal Evolution (GLIMPCE) in the late 1980s. We are revisiting seismic-reflection GLIMPCE line C...

Why do seismic hazard models worldwide appear to overpredict historical intensity observations? Why do seismic hazard models worldwide appear to overpredict historical intensity observations?
Probabilistic seismic hazard assessments (PSHAs) provide the scientific basis for building codes to reduce damage from earthquakes. Despite their substantial impact, little is known about how well PSHA predicts actual shaking. Recent PSHA for California, Japan, Italy, Nepal, and France appear to consistently overpredict historically observed earthquake shaking intensities. Numerical...
