This dataset contains a raster representing current (2017-2020) core sagebrush, growth opportunity areas, and other rangelands on tribal and federal lands that are estimated to be climate resilient into the future (2030-2060). We determined climate-resiliency by comparing current (2017-2020) core sagebrush, growth opportunity areas, and other rangelands to estimated future (2030-2060) conditions of core and growth opportunity areas under mid-century climate change (Representative Concentration Pathway 8.5) conditions (Doherty et al. 2022). The Department of the Interior (DOI) Sagebrush Keystone Initiative (KI) team worked with partners to identify areas within the sagebrush biome for strategic investments in conservation...

The Smiths cluster is named for Smith's Ferry, a location on the Payette River in western Idaho, U.S.A. The cluster is based on a 4.9 Mw earthquake nearby on February 26, 2024. The region is fairly active seismically at lower magnitudes but the cluster contains only two other events of magnitude 4.0 or larger. These three are the only events recorded teleseismically. There are few arrivals reported for this cluster beyond about 7° epicentral distance. In order to obtain good azimuthal coverage and robust statistics, many smaller events are retained. About 3/4 of the events (61 out of 80) have depth control from near-source and local-distance readings. The other 19 events are set at a default depth of 10 km with...

The Jackson cluster is named for the city of Jackson in northwest Wyoming. The seismicity in the area is diffuse and of generally low magnitude. The cluster contains over a dozen events with magnitude 4.0 or larger, but none over M5. All events are observed to at least 4° epicentral distance but there are not many teleseismic observations. The station coverage is quite dense and the location calibration is excellent. All events have depth control from near-source and local-distance readings. Number of events: 92 Calibration type: direct calibration using data to 1.0 degrees; hypocentroid calibration level = 0.4 km Epicentral calibration range: 1 - 2 km Date range: 19920404 - 20231022 Latitude range: 43.023...

This web page describes the SLU regional moment tensors for the continental US and Canada. The techniques used are described in Herrmann, R. B., H. Benz, and C. J. Ammon (2011). Monitoring the earthquake process in North America, Bull. Seism. Soc. Am. 01, 2609-2625, doi:10.1785/0120110095 .

Topography provides information about the structural controls of the Great Basin and therefore information that may be used to identify favorable structural settings for geothermal systems. Specifically, local relative topography gives information about locations of faults and fault intersections relative to mountains, valleys, or at the transitions between. As part of U.S. Geological Survey efforts to engineer features that are useful for predicting geothermal resources, we construct a detrended elevation map that emphasizes local relative topography and highlights features that geologists use for identifying geothermal systems (i.e., providing machine learning algorithms with features that may improve predictive...

Provided here is a globally distributed catalog of earthquakes and nuclear explosions with calibrated hypocenters, referred to as the Global Catalog of Calibrated Earthquake Locations or GCCEL. This dataset contains more than 22,965 earthquakes in 338 well distributed clusters. Currently there are more than 4M arrival times with the bulk being the Pg, Pn, P, Sg, Sn and S phases. The term “calibrated” refers to the property that the hypocenters are minimally biased by unknown Earth structure and that the uncertainties are meaningful. Uncertainties are calculated using empirically determined variability of the arrival time data itself, specific to each calibrated cluster of hypocenters. The data are carefully processed...

The Falls cluster is named for Falls City, Texas, a small city on the Gulf Coast plain about 60 km southeast of San Antonio. It is similar to several calibrated clusters in Oklahoma and elsewhere that are composed of induced earthquakes from oil and gas extraction activities, in this case in the Eagle Ford Shale Play. The cluster is based on a series of magnitude 4.0-4.7 events that began in the fall of 2023. A magnitude 4.8 event occurred in October 2011 but none of the earthquakes prior to 2019 (when a dense local network was installed) was well-enough connected to the recent events to be included. The four M4 events are the only ones observed at teleseismic distances. The other events in the cluster are all observed...

The Dillon cluster is named for the town of Dillon in southwest Montana, U.S.A., near the border with eastern Idaho and it includes a few events in Idaho. Most events are small but the cluster includes a 5.1 mb event on August 20, 1999 and a 5.8 mb event on July 26, 2005, a short distance north of Dillon. All events are recorded to at least 4° epicentral distance. All events have depth control from near-source and local-distance readings. Station coverage is excellent and the location calibration is very strong. Number of events: 76 Calibration type: direct calibration using data to 1.0 degrees;...

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot and Evangeline aquifers (undifferentiated), and Jasper aquifer in the greater Houston area, Texas. This dataset shows current‐year (2023) groundwater‐level altitudes for each aquifer as well as 1–year (2022–23), and 5‐year (2018–23) groundwater‐level changes for each aquifer, long‐term (1990–2023 and 1977–2023) groundwater‐level changes for the Chicot and Evangeline aquifers...
