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

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 publication, recor

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 camera was po

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. Geological Survey

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 was insta

Campaign GPS measurements on the Island of Hawai'i collected by the Hawaiian Volcano Observatory in 2019

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

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 and the p

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. During la

Digital database of the geologic map of Alamagan Volcano, northern Mariana Islands

Alamagan Volcano is a Quaternary stratovolcano along the Mariana Arc, an active subduction zone in the western Pacific Ocean. Although primarily submerged, its peak reaches above sea level, with subaerially-exposed volcanic deposits dating back through the Holocene to the late Pleistocene. These feature data represent such deposits and other geologic features of Alamagan Volcano, describing its in

Lava level and crater geometry data during the 2018 lava lake draining at Kilauea Volcano, Hawaii

In May 2018, the onset of new eruptive activity on the lower flank of Kīlauea Volcano, Hawaiʻi, accompanied the draining of the lava lake at the summit, 40 km upslope. The lava lake draining lasted over seven days, and transitioned into the largest collapse event at the summit of Kīlauea in over 200 years, with the paired flank and summit activity marking a historic episode in the modern record of

Cyclic lava effusion during the 2018 eruption of Kilauea Volcano: data release

This USGS data release includes data related to the Science magazine manuscript "Cyclic lava effusion during the 2018 eruption of Kilauea Volcano" by Patrick et al. The data release includes 1) original video as well as thermal, and timelapse images of lava in the proximal Fissure 8 channel, 2) derived estimates of lava level in the channel and bulk effusion rates (not corrected for vesicles), 3)

Differential Optical Absorption Spectroscopy data acquired during the 2018 rift eruption of Kilauea Volcano

A fissure eruption occurred in K?lauea Volcano?s Lower East Rift Zone (LERZ) from April to September 2018. During this event, volcanic gases were emitted from three active areas on the volcano. The most intense degassing occurred at the active fissures in the LERZ, thus causing parts of Hawai?i Island?s Puna district to be exposed to life-threatening sulfur dioxide (SO2) concentrations.
