Landslide, soil, and vegetation measurements following an atmospheric river storm on January 9, 2023, in the Santa Ynez Mountains, California, USA
An atmospheric river storm on January 9, 2023, produced widespread landsliding in the Santa Ynez Mountains in Santa Barbara County and Ventura County, California (USA). Landslides occurred in the footprint of the 2008 Tea Fire, 2009 Jesusita Fire, 2017 Thomas Fire, and 2019 Cave Fire, as well as in areas that had not burned in more than 15 years. Most of these landslides were shallow (less than 3-meter deep) debris slides, which mobilized into debris flows and entered drainage networks. This U.S. Geological Survey data release contains (1) an inventory of landslides that were identified with aerial photographs, (2) a tabulation of landslide source area characteristics that were measured in the field, (3) local rain gage records that span October 1, 2022, through September 30, 2023, (4) laboratory-based measurements of local soil characteristics, and (5) field-based measurements of local vegetation characteristics. The “ProcessSteps.txt” file outlines how the data were collected. The “README.txt” file describes the fields for all of the datasets. Fields with a value of “-9999” indicate that the data are not available or do not exist.
