Title:	Oregon Tsunami Data Compilation 2022
Originator:	Oregon Department of Geology and Mineral Industries
Publication Date:	20220304
Abstract:	The Oregon Department of Geology and Mineral Industries (DOGAMI) maintains the most up-to-date tsunami inundation information for the state of Oregon. Between 2010 and 2013, the DOGAMI completed modeling and mapping the next generation of tsunami evacuation maps for the coast of Oregon. Much of this source data was made available in a format that was difficult to work with and required significant processing steps to convert into a format that was easier to use. This project converted the original data into a more easily usable format and created useful derivative products. This raster mosaic dataset represents a specific parameter and event size. The individual rasters that form this mosaic vary by cell size. The purpose of the raster mosaic is to offer a coastwide raster composed of various cell sizes that reflects the variation in point spacing of the source tsunami modeling points. These data reflect a compilation of locations where roads and trails leave the tsunami inundation zone and is based on both original (2013) tsunami modeling as well as more recent modeling updates. Beginning in 2013, DOGAMI began publishing the next generation of tsunami evacuation maps for the coast of Oregon. Since then, specific areas of the Oregon coast have been updated with newer studies. The two tsunami event sizes included in this layer are 1) Event reflects a maximum-considered distant tsunami event originating from the Eastern Aleutian Islands (AKmax), and 2) the Extra-extra-large1 (XXL1) tsunami scenario, which is a Local Cascadia Subduction Zone (CSZ) tsunami scenario generated by a magnitude 9.1 earthquake. The XXL1 event has an estimated recurrence rate of at least 10,000 years.
Purpose:	These data are used to guide tsunami wayfinding signage along major highways (e.g. Highway 101) and in coastal communities to facilitate evacuation, the establishment of new critical facilities, for evacuation modeling, and for maritime preparation and guidance.
