Water chemistry data for selected hot springs and rivers in Southwest Yellowstone National Park, Wyoming

Water analyses are reported for 66 samples collected from numerous thermal and non-thermal (rivers and streams) features in the southwestern areas of Yellowstone National Park (YNP) during 2009, 2017, and 2018. Water samples were collected from sources near Boundary Creek, Bechler River, Falls River, Mountain Ash Creek, Upper Snake River, Spirea Creek, and Lewis Lake. Thes

Data repository to "Modeling ash dispersal from future eruptions of Taupo supervolcano", by S.J. Barker et al.

This data release contains supplementary material to the Geochemistry, Geophysics, Geosystems article: "Modeling ash dispersal from future eruptions of Taupo supervolcano", by S.J. Barker et al. This paper uses Ash3d model simulations to calculate the probability of a given tephra-fall thickness from eruptions of the following sizes: 0.1km3, 1 km3, 5 km3, 50 km3, and 5

Sensor data from debris-flow experiments conducted in May, 2017, at the USGS debris-flow flume, HJ Andrews Experimental Forest, Blue River, Oregon

The files consist of two types: tabulated data files and graphical map files. Data files consist of three .csv files, representing three experiment dates (2017_05_23, 2017_05_24, 2017_05_25). Each of these files contains multiple columns of data, with each column representing either a time measurement or the value of a physical quantity measured at that time (e.g., flow depth,

Digital elevation models of upper North Fork Toutle River near Mount St. Helens, based on 2006-2014 airborne lidar surveys

The lateral blast, debris avalanche, and lahars of the May 18th, 1980, eruption of Mount St. Helens, Washington, dramatically altered the surrounding landscape. Lava domes were extruded during the subsequent eruptive periods of 1980-1986 and 2004-2008. Nearly four decades after the emplacement of the 1980 debris avalanche, high sediment production persists in the North Fork Toutle R

Sensor data from natural-release experiments conducted in May, 2017, at the USGS debris-flow flume, HJ Andrews Experimental Forest, Blue River, Oregon

The files consist of six .csv files, with two files for each of three experiments (2017_05_16, 2017_05_17, 2017_05_18). One of the two files contain high-resolution data (1000 Hz) collected during the period of slope failure only, and the other files contain low-resolution data (10 Hz) for the entire duration of an experiment. Each of these files contains multiple columns of d

Hazard zone boundaries from the volcano hazards assessment for the Lassen region, Northern California

This report evaluates the volcano-related hazards, including regional mafic lava flows, silicic lava domes, pyroclastic flows, lahars, and volcanic ash, of the Lassen region, California, which is here defined as an area between the Pit River on the north and the southern limit of active Cascade volcanism, approximately 5 to 10 km south of the southern boundary of Lassen Volcanic

High-Resolution Aeromagnetic Survey of Mono Basin and Long Valley, California

A detailed aeromagnetic survey of Mono Basin and Long Valley, California was flown by EON Geosciences Inc. from October 25th to November 11th, 2012. The high-resolution helicopter survey was flown at a flightline spacing of 400 m, a flight-line azimuth of 65 degrees, a nominal flightline elevation above ground of 150 m, and consists of about 6,125 line-kilometers. Tie lines were space

Fumarole gas geochemistry and tree-ring radiocarbon data at Mammoth Mountain, California (1989-2016)

Mammoth Mountain is a dacitic dome complex located on the southwestern rim of Long Valley Caldera, California. Mammoth Mountain has exhibited unrest over the past ~30 years, characterized by seismicity over a broad range of depths, elevated 3He/4He ratios in fumarolic gas and large-scale diffuse CO2 emissions. Monitoring of this unrest has included collection of fumarole gas samples fo

Water level, temperature, and chemistry in a deep well on the summit of Kilauea Volcano, Hawaii

Kilauea, on the Island of Hawaii is one of the world’s most active volcanoes and it hosts one of the densest volcano monitoring networks. A deep well on the southwest rim of Kilauea’s caldera, often referred to informally as the “NSF Well” or the “Keller Well” was drilled in 1973 to a depth of 1,262 meters from an elevation of 1,103 meters.
