Aerial photography surveys during and after the 2018 eruption of Veniaminof Volcano, Alaska were conducted to track the evolution of the lava flow field, active volcanic vent, and glacial ice loss from the eruption. Imagery from two surveys was processed with structure-from-motion (SfM) photogrammetric methods to derive the digital elevation models (DEMs) and orthophotos in this data release. The datasets cover the active volcanic cone and intracaldera ice cap, which both show significant topographic and groundcover change between surveys, and relative to previous topographic reference data, due to the 2018 eruption and variable snow and ice cover. A syn-eruption survey on September 26, 2018 was conducted by the...

This data release presents aerial imagery and digital topography to support a geohazards assessment for an area of Sequoia National Park affected by debris flows in January 2023. Multiple atmospheric-river storms brought heavy precipitation to Sequoia National Park and the surrounding region in December 2022 and January 2023, triggering slope failures. Storm rainfall on January 9, 2023, led to shallow landslides, overland-flow erosion, and debris flows from north-facing drainages above the South Fork Kaweah River. Three of the debris flows in that part of the park buried and damaged federal assets and infrastructure: the South Fork Campground, the road used to access the campground and adjacent trails, and drainage...
