Paleoflood Investigations to Improve Flood-Frequency Estimates for Eastern Colorado
The peak-streamflow regional-regression equations (PSRREs) in the Plains hydrologic region in eastern Colorado have the largest uncertainty of any hydrologic region in Colorado. Reliable peak-streamflow information is critical for the proper design of stream-related infrastructure, such as bridges and dams, and flood-plain inundation maps. In an effort to provide more reliable peak-streamflow...
Peak-streamflow , Mean-streamflow , and Low-streamflow Equations for Western Colorado
Reliable peak-streamflow data are critical to design transportation infrastructure, such as bridges, culverts, dams, and floodplain inundation maps. At gaged sites, where sufficient long-term streamflow data have been collected, statistics can be obtained from available publications, by an analysis of available data in the U.S. Geological Survey (USGS) National Water Information System (NWIS)...

Conditions and timing of high-grade metamorphism and ductile deformation of the southern segment of the Central Anatolian Ophiolite
Ophiolitic fragments scattered over a wide area of Central Anatolia exhibit varying degrees of metamorphism, from unmetamorphosed to upper amphibolite facies, although geochemical similarities suggest they are all part of the Central Anatolian Ophiolite (CAO). Magmatic crystallization of oceanic crust in the CAO at ~ 91 Ma coincided with high...
Radwany, Molly S.; Morgan, Leah E.; Whitney, Donna L.A 36-year record of rock avalanches in the Saint Elias Mountains of Alaska, with implications for future hazards
Glacial retreat and mountain-permafrost degradation resulting from rising global temperatures have the potential to impact the frequency and magnitude of landslides in glaciated environments. Several recent events, including the 2015 Taan Fiord rock avalanche, which triggered a tsunami with one of the highest wave runups ever recorded, have called...

Perennial streamflow is limited and only exists in higher-altitude reaches of small mountain streams in both...
Gardner, Philip M.; Marston, Thomas M.; Buto, Susan G.; Brooks, Lynette E.Towards understanding relationships between atmospheric pressure variations and long-period horizontal seismic data: A case study
Variations in atmospheric pressure have long been known to introduce noise in long-period (>10 s) seismic records. This noise can overwhelm signals of interest such as normal modes and surface waves. Generally, this noise is most pronounced on the horizontal components where it arises due to tilting of the seismometer in response to...

The grass is not always greener on the other side: Seasonal reversal of vegetation greenness in aspect-driven semiarid ecosystems
Our current understanding of semiarid ecosystems is that they tend to display higher vegetation greenness on polar-facing slopes (PFS) than on equatorial-facing slopes (EFS). However, recent studies have argued that higher vegetation greenness can occur on EFS during part of the year. To assess whether this seasonal reversal of aspect-driven...
Kumari, Nikul; Saco, Patricia M.; Rodriguez, Jose F.; Johnstone, Samuel A.; Srivastava, Ankur; Chun, Kwok P.; Yetemen, OmerDeep Learning as a tool to forecast hydrologic response for landslide-prone hillslopes
Empirical thresholds for landslide warning systems have benefitted from the incorporation of soil‐hydrologic monitoring data, but the mechanistic basis for their predictive capabilities is limited. Although physically based hydrologic models can accurately simulate changes in soil moisture and pore pressure that promote landslides, their utility...
Orland, Elijah; Roering, Joshua J.; Thomas, Matthew A.; Mirus, Benjamin B.Human behavioral response in the Ridgecrest earthquakes: Assessing immediate actions based on data from “Did You Feel It?”
Human behavioral response to earthquake ground motion has long been a subject of multidisciplinary interest and research. In most versions of seismic intensity scales, human perceptions and behavior are one component of the assignment of intensity. Public health research has shown that actions taken during earthquakes have a significant impact on...
Goltz, James D.; Park, Hyejeong; Quitoriano, Vince; Wald, David J.Structure contour and overburden maps of the Niobrara interval of the Upper Cretaceous Cody Shale in the Bighorn Basin, Wyoming and Montana
The Bighorn Basin is a large intermontane sedimentary and structural basin that formed during the Laramide orogeny. The first commercial hydrocarbon production in the Bighorn Basin was established in 1906 from Cretaceous reservoirs at Garland field followed by the discovery of Greybull field in 1907. Since then, many important conventional...

Globally there were 14,588 earthquakes of magnitude 4.0 or greater in 2015. This worldwide number is on par with prior year averages of about 40 earthquakes per day of magnitude 4.0, or about 14,500 annually. The 2015 number may change slightly as the final results are completed by seismic analysts at the NEIC in Golden, Colorado.
