Crater geometry data for Puʻuʻōʻō, on Kīlauea Volcano’s East Rift Zone, in May 2018 Crater geometry data for Puʻuʻōʻō, on Kīlauea Volcano’s East Rift Zone, in May 2018
The 2018 lower East Rift Zone eruption and accompanying summit collapse of Kīlauea Volcano, Hawaiʻi, comprised one of the most impactful events on the volcano in the past 200 years, with hundreds of homes destroyed and major changes in the topography of the summit caldera. The opening stages of this eruptive sequence started on 30 April, when a magmatic dike began moving east from...
Long-term gas and heat emissions measurements, Norris Geyser Basin, Yellowstone National Park Long-term gas and heat emissions measurements, Norris Geyser Basin, Yellowstone National Park
We installed an eddy covariance station on July 10, 2018 at Bison Flat, an acid-sulfate, vapor-dominated area (0.04-km2) in Norris Geyser Basin, Yellowstone National Park, WY to monitor variations in hydrothermal gas and heat emissions. Since then, this station has measured CO2, H2O and sensible and latent heat fluxes, air temperature and pressure, and wind speed and direction on a half...
Three-dimensional grid of properties used to analyze induced seismicity recorded from 1991 to 2012 at Paradox Valley, Colorado Three-dimensional grid of properties used to analyze induced seismicity recorded from 1991 to 2012 at Paradox Valley, Colorado
Large numerical grid used for finite element and finite volume analysis of induced seismicity in Paradox Basin. The grid construction used the boundaries of three sub-horizontal surfaces; the topography, and the top and bottom of the production formation is determined from drilling and seismic reflection profiling, yielding the surface topography and thickness variations in these data...
Swarm Swarm
Swarm is a Java application designed to display and analyze seismic waveforms in real-time. Swarm can connect to and read from a variety of different static and dynamics data sources, including Earthworm & Winston wave servers, SeedLink servers, FDSN Web Services, and wave files. Swarm has both time- and frequency-domain analysis tools, along with a mapping platform. A full-screen kiosk...
Observations and model simulations of umbrella-cloud growth during eruptions of Mount Pinatubo (Philippines, June 15, 1991), Kelud Volcano (Indonesia, February 14, 2014), and Calbuco Volcano (Chile, April 22-23, 2015) Observations and model simulations of umbrella-cloud growth during eruptions of Mount Pinatubo (Philippines, June 15, 1991), Kelud Volcano (Indonesia, February 14, 2014), and Calbuco Volcano (Chile, April 22-23, 2015)
Model output to accompany the paper "Comparing Simulations of Umbrella-Cloud Growth and Ash Transport with Observations from Pinatubo, Kelud, and Calbuco Volcanoes", by L.G. Mastin and Alexa Van Eaton, published by the journal Atmosphere. The data release includes model input and output used to generate figures in the paper.

Unoccupied Aircraft Systems (UAS) video of the 2018 lower East Rift Zone eruption of K'lauea Volcano, Hawaii Unoccupied Aircraft Systems (UAS) video of the 2018 lower East Rift Zone eruption of K'lauea Volcano, Hawaii
This dataset contains Unoccupied Aircraft Systems (UAS) footage from the 2018 eruption of K'lauea Volcano's lower East Rift Zone (LERZ), Island of Hawai'i. The four-month-long eruption, from May 3 to September 5, produced lava flows that destroyed 723 structures, inundated 35.5 km2 of land, and added 3.5 km2 of new land to the Island of Hawai'i. There are 1178 UAS videos in this...
Volcanic plume heights from the summit of Kilauea Volcano, Hawai'i Volcanic plume heights from the summit of Kilauea Volcano, Hawai'i
This data release provides volcanic plume heights from the summit of Kilauea Volcano for 2008-2015, and during the eruptive events of 2018. For 2018, a Secacam Wild Vision Full HD camera with a 7mm focal length was located at 1717 m elevation approximately 15 m south of the Mauna Loa Strip Road within Hawai'i Volcanoes National Park, 19.475843degreesN, 155.363560degreesW (WGS84). The...
Ar isotope data for volcanic rocks from the northern Harrat Rahat volcanic field and surrounding area, Kingdom of Saudi Arabia Ar isotope data for volcanic rocks from the northern Harrat Rahat volcanic field and surrounding area, Kingdom of Saudi Arabia
The data are the results of mass spectrometer experiments to measure 40Ar/39Ar ages of groundmass and mineral separates from volcanic rocks in northern Harrat Rahat, Kingdom of Saudi Arabia. The data were collected using a MAP216 noble gas mass spectrometer at the USGS facility in Menlo Park, Calif. These data were collected as part of a collaborative study conducted by the U.S...
Continuous gravity data from K?lauea Volcano, Hawai?i Continuous gravity data from K?lauea Volcano, Hawai?i
This Data Release contains continuous gravity records from two instruments on Kilauea Volcano, Hawaiʻ'i the HOVL gravimeter, located on the east rim of Halema'uma'u Crater directly above the 2008-2018 summit eruptive vent, and the PUOC gravimeter, located on northern rim of Puu Oo crater on Kīlauea's East Rift Zone. Both instruments were collocated with GNSS stations. The HOVL gravimeter...

This dataset includes raw and rinex data from 2019 campaign gps data from the Island of Hawai'i in 2019. There were a total of 69 sites occupied. All data is included along with metadata, log sheets and raw/rinex data.
Compositional data on gases collected at fumaroles, hot springs, and gas vents across the Long Valley Caldera, California, 1994 ? 2020 Compositional data on gases collected at fumaroles, hot springs, and gas vents across the Long Valley Caldera, California, 1994 ? 2020
The Long Valley Caldera in eastern California formed about 760,000 years ago following the eruption of ~600 km3 of high-silica rhyolite. The Long Valley volcanic-hydrothermal system contains sufficient heat to support the Casa Diablo binary geothermal power plant sited on the margin of the resurgent dome. Present day volcanic activity is evidenced by periods of seismicity and deformation...
CO2 flux and soil temperature measurements at the Shady Rest thermal area, Mammoth Lakes, California, 2010-2019 CO2 flux and soil temperature measurements at the Shady Rest thermal area, Mammoth Lakes, California, 2010-2019
The Shady Rest thermal area (SRST) is characterized by elevated soil temperatures and CO2 emissions and associated vegetation kill. The site is located about 3 km northwest of the Casa Diablo geothermal power plant at Mammoth Lakes, California. The elevated soil temperatures and CO2 emissions are related to changes in the shallow hydrothermal system caused by geothermal fluid production...
