United States Geological Survey ice jam monitoring network on the Mohawk River in Schenectady, NY United States Geological Survey ice jam monitoring network on the Mohawk River in Schenectady, NY
The United States Geological Survey (USGS) has continuously monitored the Mohawk River between Lock 7 and Lock 9 of the New York State Barge Canal since 2011. There was a brief period, from 1914 to 1919, when a streamgage was operated at Vischer Ferry Dam (Lock 7), however, frequent damage to the gage from ice-jam related flooding in 1914 (figure 1) and 1916 resulted in establishing the...

Flood of October 31 to November 3, 2019, East Canada Creek, West Canada Creek, and Sacandaga River Basins Flood of October 31 to November 3, 2019, East Canada Creek, West Canada Creek, and Sacandaga River Basins
Between October 31 and November 3, 2019, historic flooding in parts of the Mohawk Valley and southern Adirondack region resulted in one fatality, an estimated $33 million in damages, and the declaration of a state of emergency for 13 New York counties. Flooding resulted from high-intensity rainfall within a 24-hour period between October 31 and November 1, 2019, at the end of an October...

Summary of annual repeat magnetotelluric surveys of the Geysers geothermal field Summary of annual repeat magnetotelluric surveys of the Geysers geothermal field
As part of a multi-year project, funded by the California Energy Commission, annual magnetotelluric (MT) surveys have been collected at The Geysers geothermal field in northern California with the goal of measuring temporal changes within the steam field. The repeat surveys started in 2021 and repeated a 2017 survey (Peacock et al., 2020) with further extension to the southern part of...

Updated three-dimensional temperature maps for the Great Basin, USA Updated three-dimensional temperature maps for the Great Basin, USA
As part of the periodic update of the geothermal energy assessments for the USA (e.g., last update by Williams and others, 2008), a new three-dimensional temperature map has been constructed for the Great Basin, USA. Williams and DeAngelo (2011) identified uncertainty in estimates of conductive heat flow near land surface as the largest contributor to uncertainty in previously published

Monthly variation in home range of a steppe-dwelling raptor Monthly variation in home range of a steppe-dwelling raptor
Birds in steppe landscapes change their behaviour over the annual cycle. We used GPS telemetry to track 12 steppe-dwelling adult Ferruginous Hawks (Buteo regalis) to understand how their home ranges varied across the year. Home range sizes of territorial adult hawks showed strong intra-annual variation, being smallest from April to June, and largest from July to October. Patterns in home...

Dynamics of the nesting group of the steppe eagle in Aktobe region in 2018-2023 Dynamics of the nesting group of the steppe eagle in Aktobe region in 2018-2023
Kazakhstan is a key area for the conservation of the steppe eagle, which is classified as an endangered species by the IUCN. Systematic work on monitoring changes in its number and reproductive success is carried out in protected areas. The remaining steppe spaces are explored sporadically. Our work partially fills this gap. Over 5 years of monitoring the nesting group in the north of...

Liquefaction timing and post-triggering seismic energy: A comparison of crustal and subduction zone earthquakes Liquefaction timing and post-triggering seismic energy: A comparison of crustal and subduction zone earthquakes
The objective of the study is to assess when liquefaction is triggered in a suite of ground motions following simplified approaches and measure the remaining post-triggering energy content of those ground motions. For liquefaction-induced deformations, current simplified analysis procedures do not directly incorporate temporal effects and rely on peak transient intensity measurements...

Using geologic mapping to understand temporal and spatial relations of closely clustered to concurrent latest Holocene surface ruptures on two intersecting faults, south-central Mojave Desert, California Using geologic mapping to understand temporal and spatial relations of closely clustered to concurrent latest Holocene surface ruptures on two intersecting faults, south-central Mojave Desert, California
The Pinto Mountain Fault Zone (PMFZ) marks a major structural boundary between east-oriented sinistral faults of the eastern Transverse Ranges (to the south) and northwest-oriented dextral faults of the south-central Mojave Desert (to the north). These structural fault systems comprise sinistral and dextral deformational domains of the Eastern California Shear Zone (ECSZ) that intersect...

Recent applications of the USGS National Crustal Model for Seismic Hazard Studies Recent applications of the USGS National Crustal Model for Seismic Hazard Studies
The U.S. Geological Survey is developing the National Crustal Model (NCM) for seismic hazard studies to facilitate modeling site, path, and source components of seismic hazard across the conterminous United States. The NCM is composed of a 1km grid of geophysical profiles, extending from the Earth’s surface into the upper mantle. It is constructed from a threedimensional (3D) geologic...
