On February 14th, 2019, a strong atmospheric river storm (AR4 on the Atmospheric River scale of Ralph et al., 2019) struck California. The heavy rainfall caused landslides in both northern and southern California (Hatchett et al., 2020). This data release includes two subsets of mapped shallow landslide source locations in the vicinity of western Riverside County, California, where sufficient post-event imagery was available within Google Earth (image date: August 15, 2019). The data release includes: 1) .csv files containing the point locations of shallow hillslope landslides, 2) .zip files containing shapfiles (.shp) of the mapped study areas. Ralph, F., Rutz, J. J., Cordeira, J. M., Dettinger, M., Anderson,...

We have constrained the age of the Nussbaum Gravel at Baculite Mesa, CO using cosmogenic Al-26/Be-10 isochron burial dating. Two samples, a coarse sand and a fine gravel, were prepared for burial dating at the Reston Cosmogenic Nuclide (RECON) Lab and measured via accelerator mass spectrometry at the Purdue Rare Isotope Measurement (PRIME) Lab. The results of this work are summarized in the file “BaculiteMesa_SiteLocation_Odom.csv”, which contains site data and burial age calculations; measurements of aluminum-26 and beryllium-10, as well as related data, are located in respective .csv files. We calculated respective minimum and maximum burial ages for the sand (1.25 ± 0.08 Ma and 1.66 ± 0.12 Ma) and gravel (1.44...

The 2018 eruption from the lower East Rift Zone of Kīlauea volcano, on the Island of Hawaiʻi, was one of the most significant and destructive events on the volcano in the past 200 years (Neal and others, 2019; Patrick and others, 2020; Anderson and others, 2023; Mulliken and others, 2024). Between May and September of that year, 24 fissures opened on the lower flank of the volcano, producing lava fountains and expansive lava flows that covered an area of 36 km2 (Neal and others, 2019; Zoeller and others, 2020). Effusion rates at the dominant vent, fissure 8, were often >100 m3 s-1, and the total eruptive volume is estimated at 0.9–1.4 km3 (Dietterich and others, 2021) making it one of the most voluminous effusive...

The area surrounding La Conchita, California (CA), USA experienced significant landslides and debris flows following a storm on January 10th, 2005, including a deadly deep-seated landslide that destroyed 13 houses and caused 10 fatalities (Jibson, 2006). This data release documents the locations of shallow landslide source locations in the vicinity of the deadly 2005 La Conchita landslide. Landslide locations were mapped as points using post-event imagery available in Google Earth. The data release includes: 1) .csv file containing the point locations of shallow hillslope landslides, 2) .zip file containing shapefile (.shp) of the mapped study area. References: Jibson, R. W. (2006). The 2005 La Conchita, California,...

This data release includes multiple datasets obtained during the study of north-facing fault scarps along the Seattle fault zone. It includes geochronological data and field measurements from the Vasa Park trench (47.576618°, -122.119524°) near Bellevue, WA, and the Rose Hip trench (47.597°, -122.535°), Lyle Beach terrace site (47.597,-122.542), and Mill Pond site (47.597,-122.525) on south Bainbridge Island, WA. This data release also contains ground-based geomagnetic data of multiple transects across the Seattle fault zone on south Bainbridge Island and Point Glover.

We have dated a boulder field in Zepp, VA using cosmogenic Be-10 exposure dating. Three samples taken from boulders at three elevations in the boulder field (804 m asl, 818 m asl, and 831 m asl) were processed at the Reston Cosmogenic Nuclide (RECON) Lab and measured via accelerator mass spectrometry at the Purdue Rare Isotope Measurement (PRIME) Lab. The results of this work are summarized in the file “Zepp_Exposure_Beryllium10_Odom.csv”. This file contains all relevant sample location data, as well as input variables for exposure age calculations. We employed the CRONUS v.3 exposure age calculator (Balco et al., 2008) to estimate exposure ages for these samples and report exposure ages derived using the LSDn time-dependent...
