Landslide Inventory for Kosrae, Federated States of Micronesia (FSM) 2005 - 2023
November 4, 2024
Landslides hazards pose a serious threat to people and infrastructure in the Federated States of Micronesia (FSM). To develop a comprehensive understanding of the landslides hazards in FSM, the USGS-USAID Landslide Disaster Assistance Team (LDAT) has put together landslide inventories for each state using satellite imagery.
Mapping was done using RGB satellite imagery from Maxar, Planet Labs, and Google Earth. This inventory is for Kosrae state and covers all available imagery between January 2005 and October 2023. Landslides are dated by a window of occurrence based on the last images before and first image after the occurrence of the landslide. Each event was mapped using a point at the center of the headscarp (points_Kos), and, when possible, affected area polygons (area_Kos), runout lines (runout_Kos), and headscarp lines (headscarp_Kos). Due to the dense vegetation, frequent cloud cover, and poor spatial and temporal resolution of available imagery, it was difficult to map headscarps and runouts for every event. However, headscarp width and runout distance are mapped where possible. The attribute table for points_Kos, contains a visual-based classification of the land use and vegetation, as well as if the event affected streams, buildings, or utilities (for example, roads). Each event is also labeled with a level of confidence for occurrence and location.
