Landslide Headscarps in Marine Terraces along the Pacific Coast of Washington and Oregon
Description
We present a set of 617 landslide headscarps along marine terraces in Oregon and Washington State. Headscarps (as polyline features) were mapped from <1 m resolution lidar in the first major terrace along the Pacific coastline of Washington and Oregon states. Only slides originating in mapped sedimentary rock units, or sedimentary rock capped by a veneer of glacial till, were included. Mapping was also limited to only include landslides that could be categorized as rotational (that is, movement of the landslide shows evidence for sliding along a circular or curved path. Other landslide failure styles present along the study region, like translational slides, ravels, and rockfall, are omitted from this dataset. Data are provided in shapefile (.shp) and .csv.
