Lava level and crater geometry data during the 2018 lava lake draining at Kīlauea 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 ep

Tiltmeter data from Kīlauea Volcano, Hawaii, spanning the 2018 eruption and earthquake sequence

Data collected by 11 borehole tiltmeters operated by the U.S. Geological Survey on Kīlauea Volcano, on the Island of Hawai'i. Data was collected between 30 April, 2018 and 5 August, 2018. Among the features captured by this data set are: the collapse of Puʻuʻōʻō on 30 April, 2018, the migration of magma down the East Rift Zone from 30 April to 3 May%2

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 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

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,

Gas and heat emission measurements at Solfatara Plateau Thermal Area, Yellowstone National Park (May-September 2017)

From May to September 2017 measurements of gas and heat emissions were made at Solfatara Plateau Thermal Area, an acid-sulfate, vapor-dominated area in Yellowstone National Park, Wyoming. An eddy covariance system measured half-hourly CO2, H2O and sensible and latent heat fluxes, air temperature and pressure, wind speed and direction and soil moisture. A Multi-GAS instrument measured
