InSAR time-series data of Mauna Loa, Hawai'i from 2015 to 2024 InSAR time-series data of Mauna Loa, Hawai'i from 2015 to 2024
This dataset contains InSAR (Interferometric Synthetic Aperture Radar) time series data of the deformation state of Mauna Loa from 2015 to 2024. There are four total InSAR timeseries: A descending orbital perspective from 2015 to 2022 created using LiCSBAS (HI_filt_des.h5). A ascending orbital persepctive from 2015 to 2022 created using LiCSBAS (HI_filt_asc.h5). A descending orbital...
Measurements and photographs of permafrost cores drilled on the Arctic Coastal Plain, Alaska Measurements and photographs of permafrost cores drilled on the Arctic Coastal Plain, Alaska
As the Arctic physical environment undergoes rapid change, permafrost conditions also are shifting. Thawing of ice-rich permafrost can cause terrain instability and compromise infrastructure as the permafrost excess ice content (EIC) melts – EIC refers to the volume of ground ice that exceeds the soil’s pore space when thawed. This dataset provides EIC depth measurements from 38...
10-Minute GPS Monitoring Data for the Cleveland Corral landslide near U.S. Highway 50, El Dorado County, California 10-Minute GPS Monitoring Data for the Cleveland Corral landslide near U.S. Highway 50, El Dorado County, California
This data release documents movement of the toe of Cleveland Corral Landslide, El Dorado County, CA from October 1, 2016, to September 30, 2017, based on GPS data from near real-time monitoring. Raw GPS data from L1-only receivers were recorded in 15 second epochs using data acquisition systems and radio telemetry developed by the USGS Volcano Hazards Program. The overall system, named...
Location, length, and height of landslides triggered by tropical storm Chata'an in Chuuk, Federated States of Micronesia Location, length, and height of landslides triggered by tropical storm Chata'an in Chuuk, Federated States of Micronesia
In 2002, tropical storm Chata’an triggered more than 250 landslides in Chuuk, Federated States of Micronesia (Harp and others, 2004). This data release includes shapefiles of the original mapping from oblique aerial photographs of landslide-affected areas (source and runout) (Harp and others, 2004), extraction of height (H) and length (L) from the original mapped landslides, and revised...
Paleomagnetic Data from Newberry Volcano, Oregon, collected from 1977-2018 Paleomagnetic Data from Newberry Volcano, Oregon, collected from 1977-2018
This dataset consists of 424 paleomagnetic sites from Newberry Volcano. 15 sites were analyzed at the natural remanent magnetization level, 256 sites were analyzed with blanket demagnetization, and 153 sites were analyzed with modern stepwise demagnetization protocols. 412 sites yield acceptable paleomagnetic data.
Electron microprobe analyses of olivine and oxide grains from the Five Fingers lava flows in the northern Harrat Rahat volcanic field, Kingdom of Saudi Arabia Electron microprobe analyses of olivine and oxide grains from the Five Fingers lava flows in the northern Harrat Rahat volcanic field, Kingdom of Saudi Arabia
We present new electron microprobe analyses of olivine and oxide grains hosted in three young basaltic lava flows located in northern Harrat Rahat, a distributed volcanic field in central-western Saudi Arabia.These lavas, collectively referred to as the Five Fingers, erupted at ca. 24 ka from three elongate vent complexes that fall along a common lineament. Integrated with existing...
Overflight thermal imagery of the eruption of the north crater of Mount Young, Semisopochnoi Island, Alaska, 2021 Overflight thermal imagery of the eruption of the north crater of Mount Young, Semisopochnoi Island, Alaska, 2021
The Alaska Volcano Observatory conducted overflights of the active north crater of Mount Young on Semisopochonoi Island, Alaska, during its eruption in 2021 to capture the volcanic and hydrothermal activity within the vent during (May 30) and between (June 8) ash emissions. Thermal videos were acquired to see through the ash and steam and observe the features within the active crater...
Simulated floods, sediment entrainment, and debris-flow inundation in the Toutle and Cowlitz River valleys resulting from hypothetical dam breaches of Spirit Lake, Washington Simulated floods, sediment entrainment, and debris-flow inundation in the Toutle and Cowlitz River valleys resulting from hypothetical dam breaches of Spirit Lake, Washington
This data release contains postprocessed model output from a set of numerical simulations of hypothetical outburst floods of Spirit Lake, downstream sediment entrainment, and emergent debris flows, in the Toutle and Cowlitz River valleys in Washington State. The data release provides debris-flow inundation extent, travel times, maximum depths, and model input data (including hypothetical...

These data are geochemical analyses of rock and mineral samples from interval one at Clear Lake volcanic field, California.
Argon Geochronology Data from Pleistocene Volcanic Deposits Along the Pit River, California Argon Geochronology Data from Pleistocene Volcanic Deposits Along the Pit River, California
Argon geochronology results date eruptions of mapped volcanic deposits north and south of the PIt River in the California Cascades. This data release includes both raw data and summary data. Summary data are the results USGS geochronologist(s) recommend be cited in geologic history publications.
Sample details and compositional data collected during the 2024 Southwest Rift Zone and middle East Rift Zone eruptions of Kīlauea, Island of Hawaiʻi Sample details and compositional data collected during the 2024 Southwest Rift Zone and middle East Rift Zone eruptions of Kīlauea, Island of Hawaiʻi
Samples for the 2024 Kīlauea eruptions in the Southwest Rift Zone and middle East Rift Zone were collected by the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) field teams from within publicly closed areas of Hawai‘i Volcanoes National Park in cooperation with the National Park Service. This data release presents sample metadata, whole rock ED-XRF, whole rock WD-XRF, whole...
Physical volcanology data and measurements (grain size, grain shape, thickness, maximum clast size, ballistic block size, and componentry) from the May 11–27, 1924 tephra deposits of Halemaʻumaʻu crater, Kīlauea volcano, Island of Hawaiʻi Physical volcanology data and measurements (grain size, grain shape, thickness, maximum clast size, ballistic block size, and componentry) from the May 11–27, 1924 tephra deposits of Halemaʻumaʻu crater, Kīlauea volcano, Island of Hawaiʻi
Over 16 days from May 11–27, 1924, there were more than 50 explosions from Halemaʻumaʻu crater at Kīlauea volcano on the Island of Hawaiʻi. These explosions ejected blocks weighing >12,000 kg, as well as extremely fine ash to lapilli size tephra. The greatest thicknesses of tephra were at the summit region of Kīlauea, but some tephra fell on Wood Valley, Pāhala, and Waiʻōhinu to the...
