Data

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...

This data release contains data collected during campaign Global Navigation Satellite Systems (GNSS; formerly only the Global Positioning System or GPS) surveys conducted at Mount Hood. 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.

Observations of locations where the August 18th, 1992 eruption of Mount Spurr was heard and not heard around Alaska.

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...

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...

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...

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...

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...

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.

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...

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...
