Interferometric Synthetic Aperture Radar (InSAR) Data for the 2024–2025 Diking Episode, Fentale-Dofen Segment, Ethiopian Rift Interferometric Synthetic Aperture Radar (InSAR) Data for the 2024–2025 Diking Episode, Fentale-Dofen Segment, Ethiopian Rift
This dataset contains Interferometric Synthetic Aperture Radar (InSAR) observations acquired during the 2024–2025 diking episode along the Fentale-Dofen segment of the Ethiopian Rift. The data were collected to image ground deformation associated with magmatic intrusion and faulting processes in an active rift system. The dataset includes wrapped interferograms measuring line-of-sight...
Gas and heat emission measurements at the Mud Volcano area, Yellowstone National Park Gas and heat emission measurements at the Mud Volcano area, Yellowstone National Park
We measured soil CO2 fluxes on grids with the accumulation chamber method on July 15-17, 2021, September 10, 2022, and May 6-7, 2025, at Mud Volcano, an acid-sulfate, vapor-dominated area in Yellowstone National Park, WY. We also monitored variations in CO2, H2O and sensible and latent heat fluxes, air temperature and pressure, and wind speed and direction on a half-hourly basis from...
Argon geochronologic data from New Zealand's Ruapehu and Tongariro Volcanoes used to illustrate geochronology systematics Argon geochronologic data from New Zealand's Ruapehu and Tongariro Volcanoes used to illustrate geochronology systematics
Understanding the eruptive histories and petrogenetic models that underpin hazard assessments at active volcanoes typically requires high-precision ages for late Pleistocene to Holocene lava flows. These data vary in quality, typically related to textural and chemical variations in lava flow samples. These samples were part of an existing 40Ar/39Ar dataset for andesitic-dacitic rocks...
Campaign GNSS Measurements Collected at Newberry Volcano by the Cascades Volcano Observatory Campaign GNSS Measurements Collected at Newberry Volcano by the Cascades Volcano Observatory
This data release contains data collected during campaign Global Navigation Satellite Systems (GNSS; formerly only the Global Positioning System or GPS) surveys conducted at Newberry Volcano. A survey in any given year may contain data from a subset of established sites depending on access, personnel, and the condition of the GNSS monument. For each site, we include raw data in binary or...

Data release for the output of infrasound propagation modeling for the August 18th, 1992 eruption of Mount Spurr.
Reports of Hearing and Not Hearing the 1992 eruption of Mount Spurr Reports of Hearing and Not Hearing the 1992 eruption of Mount Spurr
Observations of locations where the August 18th, 1992 eruption of Mount Spurr was heard and not heard around Alaska.
Radiocarbon ages from sites in Peru generated during joint volcano hazards projects carried out by the U.S. Geological Survey Volcano Disaster Assistance Program, Instituto Geofisico del Peru, and Instituto Geologico, Minero y Metalurgico del Peru Radiocarbon ages from sites in Peru generated during joint volcano hazards projects carried out by the U.S. Geological Survey Volcano Disaster Assistance Program, Instituto Geofisico del Peru, and Instituto Geologico, Minero y Metalurgico del Peru
We present the results of 14C age analysis of samples collected during multiple projects that are part of an ongoing, joint initiative of the U.S. Geological Survey Volcano Disaster Assistance Program with the Instituto Geológico Minero y Metalúrgico and Instituto Geofísico del Perú. These projects are part of a wider effort to better understand Peru’s many volcanoes and provide baseline...
InSAR time-series data of Mauna Loa, Hawai'i from 2015 to 2024 (ver. 1.1, January 2026) InSAR time-series data of Mauna Loa, Hawai'i from 2015 to 2024 (ver. 1.1, January 2026)
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...
