Landslide Inventory for Chuuk, Federated States of Micronesia (FSM) 2003 - 2022

Metadata Updated: September 17, 2025

Landslides hazards pose a serious threat to people and infrastructure in 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 Chuuk state and covers all available imagery between July 2003 and September 2022. 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_Chu), and, when possible, affected area polygons (area_Chu), runout lines (runout_Chu), and headscarp lines (headscarp_Chu). 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_Chu, 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. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
