Aleutian Islands Coastal Resources Inventory and Environmental Sensitivity Maps: FAULTS (Fault Lines)

Data provided by  National Oceanic and Atmospheric Administration

This data set is a compilation of faults mapped by the United States Geological Survey (USGS) and published in USGS bulletin series 1028 (1956-1971). These bulletins are the last published attempt at mapping structure and stratigraphy of the Aleutians on an island-by-island basis. Only faults that manifest themselves on land were included in the USGS reports. Faults were transcribed from these bulletins onto the ESI maps. On the ESI maps, the faults are portrayed as linear features, with no map indication of their type (normal vs. thrust).This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Aleutians East Borough and Aleutians West Coastal Resource Service Area (CRSA). These data identify the marine and coastal environments and wildlife. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.
