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.

Volcanic plume heights from the summit of Kilauea Volcano, Hawai'i

This data release provides volcanic plume heights from the summit of Kīlauea 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 Hawaiʻi Volcanoes National Park, 19.475843°N, 155.363560°W (WGS84). The camera was pointed...

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.

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. Du...

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 direct

Continuous gravity data from Kīlauea Volcano, Hawaiʻi

This Data Release contains continuous gravity records from two instruments on Kīlauea Volcano, Hawaiʻi: the HOVL gravimeter, located on the east rim of Halemaʻumaʻu Crater directly above the 2008-2018 summit eruptive vent, and the PUOC gravimeter, located on northern rim of Puʻu ʻŌʻō crater on Kīlauea’s East Rift Zone. Both inst

Silicified wood from around Old Faithful Geyser, Yellowstone National Park

Old Faithful Geyser in the Upper Geyser Basin of Yellowstone National Park is one of the best studied geysers in the world. Under research permit YELL-SCI-8030, samples from 13 silicified tree remnants were collected adjacent to the Old Faithful Geyser cone in April and November 2019. The silicified wood samples were dated using the radiocarbon (14C) method and were analyzed by scanning ele...

Silicified wood from around Old Faithful Geyser, Yellowstone National Park: Scanning Electron Microscopy (SEM)

Silicified wood samples were vacuum impregnated with epoxy, sectioned, and sputter coated with 10 nm Au/Pd at the U.S. Geological Survey, Menlo Park, CA. Samples were imaged in a Tescan VEGA3 Scanning Electron Microscope (SEM) equipped with an Oxford 150 mm2 X-MaxN large area energy dispersive spectrometer at the U.S. Geological Survey, Menlo Park, CA. Backscatter (BSE) im

Silicified wood from around Old Faithful Geyser, Yellowstone National Park: Radiocarbon Dating

Radiocarbon dating of silicified wood was performed at the U.S. Geological Survey’s Radiocarbon Laboratory in Denver, Colorado. All samples were chemically treated using the standard acid-base-acid (ABA) procedure before being combusted online in the presence of excess high-purity oxygen. Water and other contaminant gases were removed using cryogenic separation techniques, and the

Sulfur dioxide emission rates from Kīlauea Volcano, Hawaii, 2008-2013

Kīlauea Volcano on the Island of Hawai‘i was in a state of nearly continuous eruption from 1983 – 2018. Large amounts of sulfur dioxide gas (SO2) were released from the volcano’s East Rift Zone (ERZ) during the entire eruptive period, and from the Overlook vent at the summit of the volcano from 2008-2018. This data release presents ground-based estimates of

Digital elevation model of Kilauea Volcano, Hawai'i, based on July 2019 airborne lidar surveys

The 2018 eruption of Kilauea Volcano on the Island of Hawai'i saw the collapse of a new, nested caldera at the volcano's summit, and the inundation of 35.5 square kilometers (13.7 square miles) of the lower Puna District with lava. Between May and August, while the summit caldera collapsed, a lava channel extended 11 kilometers (7 miles) from fissure 8 in Leilani Estates to Ka
