Sandy ocean beaches in the United States are popular tourist and recreational destinations and constitute some of the most valuable real estate in the country. The boundary between land and water along the coastline is often the location of concentrated residential and commercial development and is frequently exposed to a range of natural hazards, which include flooding, storm effects, and coastal erosion. In response, the U.S. Geological Survey (USGS) is conducting a national assessment of coastal change hazards. One component of this research effort, the National Assessment of Shoreline Change Project, documents changes in shoreline position as a proxy for coastal change. Shoreline position is an easily understood...

The 2018 lower East Rift Zone eruption of Kilauea Volcano began in the late afternoon of 3 May, with fissure 1 opening and erupting lava onto Mohala Street in the Leilani Estates subdivision, part of the lower Puna District of the Island of Hawai'i. For the first week of the eruption, relatively viscous lava flowed only within a kilometer (0.6 miles) of the fissures within Leilani Estates, before activity shifted downrift (east-northeast) and out of the subdivision during mid-May. Around 18 May, activity along the lower East Rift Zone intensified, and fluid lava erupting at higher effusion rates from the downrift fissures reached the ocean within two days. Near the end of May, this more vigorous activity shifted...

The natural resiliency of the New Jersey barrier island system, and the efficacy of management efforts to reduce vulnerability, depends on the ability of the system to recover and maintain equilibrium in response to storms and persistent coastal change. This resiliency is largely dependent on the availability of sand in the beach system. In an effort to better understand the system's sand budget and processes in which this system evolves, high-resolution geophysical mapping of the sea floor in Little Egg Inlet and along the southern end of Long Beach Island near Beach Haven, New Jersey was conducted from May 31 to June 10, 2018, followed by a sea floor sampling survey conducted from October 22 to 23, 2018, as part...

The Okinawa cluster is named for the island of Okinawa in the Ryukyu Islands. Although there are deeper events in the area, only events with depths less than about 35 km were retained in the cluster. The cluster contains one large event, an Ms 6.5 event on March 2, 1980 to the west of the island that is likely associated with back-arc spreading. All events have depth constraint from arrivals at near- or local-distances, or from teleseismic depth phases in a few cases. Although the setting is broadly oceanic, the Ryukyu Islands are thought to be part of a remannt continental sliver, so it is not so surprising that a crustal model very close to ak135 fits the observed arrival time data well. ...
To support research on remote sensing of rivers, specifically estimation of water depth from passive optical image data, hyperspectral image data and supporting depth measurements were collected on the Kootenai River in northern Idaho, September 27, 2017. This data release provides access to hyperspectral image acquired through this project and the supporting field-based measurements of depth and water column optical properties are available through related data releases. The hyperspectral image data were acquired by Quantum Spatial Inc. (QSI) using the ITRES CASI 1500H imaging system deployed from a Cessna Caravan manned aircraft from a flying height of 1000 m above ground level. Initial geometric and radiometric...

The Siah Kuh cluster is named after the village of Siah Kuh (Black Mountain) in Gilan Province, Iran. It consists of only 16 events, the largest being the M4.3 event on September 5, 2005. There's a fairly large azimuthal gap to the east, but the cluster is well calibrated at a level of 1.4 km by using data up to 1.6 degrees. Focal depths of almost all events are constrained with local-distance readings, except for the oldest event in the cluster (January 6, 2005) which is set to a default of 11 km. Number of events: 16 Calibration type: direct calibration using data to 1.6 degrees; hypocentroid...
The Hakodate cluster is named for the city of Hakodate at the south end the island of Hokkaido, Japan. The cluster extends southward to the northern tip of Honshu. Over half the events in the cluster are associated with an earthquake swarm in late March 2000 on the southern flank of Mt. Usu, an active volcano in southern Hokkaido. The distribution of stations is quite good and location calibration is straight-forward. Number of events: 39 Calibration type: direct calibration using data to 1.0 degrees; hypocentroid calibration level = 1.1 km Epicentral calibration range: 1 - 2 km Date range:...
The “Biophysical assessment for indemnity selection of federal lands in Colorado: Indemnity Unit locations” dataset delineates the spatial locations of 89 Indemnity Units, comprising 339 parcels of federal lands. These lands, currently managed by the Bureau of Land Management (BLM), are under consideration for transfer of ownership to the State of Colorado in compensation for federal lands not available for transfer at the time of statehood. The Indemnity Units total 23,130 acres of surface and mineral estate and 6,150 acres of mineral estate only. The specific land parcels to be transferred to the State will be finalized after an environmental analysis is completed, as required by the National Environmental Policy...

The Ahel cluster is named for the village of Ahel in Fars Province, Iran. This cluster consists of 184 events including the October 31, 1956 Gowdeh earthquake (Magnitude 6.6) and fourteen more older events prior to 1980. Calibration is greatly aided by data from a temporary network deployed by Farzam Yamini-Fard (IIEES). A.R. Ghods (IASBS) repicked many of the arrival times from Iranian networks, including S-P data from the INSM network of accelerometers (BHRC). Focal depths of 23 events are constrained with near-source data, 15 are set by local-distance data, and reminder are fixed to a cluster default of 12 km. Further information about this cluster is contained in: Karasözen et al. (in preparation), Seismotectonics...
The Turt cluster is named for a small settlement on the northeastern shore of Lake Khovsgol in northern Mongolia. The cluster crosses the border with Russia, into Buryatia. The cluster was formed around a 6.7 Mw earthquake on January 11, 2021. This event was followed by a large number of aftershocks which could have been included in the cluster but the coverage from local stations for these events was unbalanced and the location calibration tended to become unstable when a large number of them were included. Most of them were only recorded at regional distances. Several of the largest aftershocks are included. It was difficult to obtain adequate azimuthal coverage for this cluster but the final selection of events...
wy_lvl2_finescale: Wyoming hierarchical cluster level 2 (fine-scale) for Greater sage-grouse We developed a hierarchical clustering approach that identifies biologically relevant landscape units that can 1) be used as a long-term population monitoring framework, 2) be repeated across the Greater sage-grouse range, 3) be used to track the outcomes of local and regional populations by comparing population changes across scales, and 4) be used to inform where to best spatially target studies that identify the processes and mechanisms causing population trends to change among spatial scales. The spatial variability in the amount and quality of habitat resources can affect local population success and result in different...

The Potenza cluster is named for the city of Potenza in the region of Basilicata in southern Italy. It includes the Irpinia earthquake (Ms 6.8) on November 23, 1980, and includes a number of moderate-sized events in recent years. The number of seismic stations in the source region increased markedly in 1999 and again in 2010, making direct calibration very easy. The velocity structure was refined with a subset of recent events for which free-depth relocations could be done. All events have depth constraint from near-source or local distance readings, or for a couple events, teleseismic depth phases. ...
Landscape conservation cooperatives (LCCs) are conservation-science partnerships between the U.S. Fish and Wildlife Service, U.S. Geological Survey (USGS), and other federal agencies, states, tribes, NGOs, universities and stakeholders within a geographically defined area. They inform resource management decisions to address national-scale stressors-including habitat fragmentation, genetic isolation, spread of invasive species, and water scarcity-all of which are accelerated by climate change.
This map shows the channel boundary (2011) of the Colorado River mainstem between the Utah Colorado border and the upper pool of Lake Powell, Utah (146 miles). The channel boundary was mapped from public available NAIP imagery flown on June 28, 2011, when the river flow was 886 m3/s at the Cisco gage. The channel is subdivided into channel types: fast water (main channel, secondary channel), and still water types (backwater, isolated pool and tributary channel).
