Initial Observations of Landslides triggered by the 2018 Anchorage, Alaska earthquake

This data release provides the locations of 43 landslides that occurred during the 2018 Anchorage, Alaska earthquake mapped from high-resolution lidar (1-m). Lidar data can be accessed via the Alaska Division of Geological and Geophysical Surveys elevation portal (https://elevation.alaska.gov). Each landslide is represented as a point corresponding to the approximate location of the mid-point of the landslide head scarp. Wherever possible, the outline of (39) landslides are also provided as polygons. Areal coverage of this data release is constrained to the availability of the 1-m resolution lidar. Within this area, this data builds upon Grant et al. (2020) by more accurately locating those observed landslide features and mapping their extent where possible.
