These data are a series of telecommunications voice and data restoration percentages for 17 counties affected by the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data for telecommunications demand served are derived from residual network capacity based on potential hazard information (for example, ground shaking and liquefaction), assumptions about dependence on electric power restoration, and assumptions about network congestion caused by demand surge. Various resilience cases pertain to assumptions about the presence of backup power (for example, batteries or generators), ability to truck in fuel and...

This data release contains results of model simulations of a plume at Kilauea volcano that occurred on 20 December 2020. The ash-poor plume was produced when lava flowed into a water lake at the summit of Kilauea volcano. Simulations were conducted to constrain the conditions under which the plume rose to its observed height. The analysis and results are described in the accompanying paper: Cahalan RC, Mastin L, Van Eaton A, Hurwitz S, Smith AB, Dufek J, Solovitz SA, Patrick M, Schmith J, Parcheta C, Thelen W, Downs DT (2023 (in press)) Dynamics of the December 2020 ash-poor plume formed by lava-water interaction at the summit of Kīlauea Volcano, Hawaiʻi.

In support of U.S. Geological Survey invasive carp research examining aggregations of invasive carp in the tail water of dams, water velocity measurements were made at cross sections in the Illinois River below Starved Rock Lock and Dam on June 16, 2021. A total of 16 cross sections were surveyed, with two transects per cross section. Water depth and crew safety limited the extent of the survey. The discharge in the Illinois River at Starved Rock Lock and Dam at the time of data collection was approximately 185.7 cubic meters per second. The data were processed in the Velocity Mapping Toolbox (VMT) v.4.09 (Parsons and others, 2013) to obtain a depth-averaged velocity field for each cross section from paired transects...

Abstract The isotopic composition of Pb in fugitive dust suspended by a vehicle from 13 unsurfaced roads in Missouri was measured to identify the source of Pb within an established long-term mining area. A three end member model using 207Pb/206Pb and concentration as tracers resulted in fugitive dust samples plotting in the mixing field of well characterized heterogeneous end members. End members selected for this investigation include the 207Pb/206Pb for 1) a Pb-mixture representing mine tailings, 2) aerosol Pb impacted soils within close proximity to the Buick secondary recycling smelter, and 3) an average of soils, rock cores and drill cuttings representing the background characteristics. Aqua regia total concentrations...

The Bonnet Carré Spillway (BCS), located about 28 miles northwest of New Orleans, was constructed by the US Army Corp of Engineers in the early 1930s as part of an integrated flood-control system for the lower Mississippi River (MR). The BCS control structure consists of 350 individual bays that can be opened to divert water from the river to Lake Pontchartrain to relieve pressure on downstream levees. Lake Pontchartrain (LP) is hydrologically connected to the Mississippi Sound (MS Sound) and the Gulf of Mexico and is more accurately characterized as an estuarine embayment. BCS openings have occurred twelve times prior to 2019 because of high Mississippi River stages, typically in late spring. In 2019, the spillway...
