Utah - Current Level to 1800 feet
Tsunami impacts from water disturbing events on the Pacific Ocean such as landslides (above and underwater), volcanic eruptions, earthquakes and meteor impacts are all possibilities. With the Ring of Fire wrapping the Pacific plate, the chances are much higher that volcanic eruptions and/or earthquake activity will create large waves on the West coast of the US. As an example, a large earthquake on the Cascadia fault occurs once every 300-1000 years. On January 26, 1700, a rupture of the entire fault occurred and caused a tsunami that impacted Hawaii, Japan and Australia. It has been 312 years since the last fault rupture at this location and there are many like it surrounding the Pacific plate.

Utah in particular is buffered by California and Nevada if one were to occur and this series of maps shows what could happen if a large tsunami hit the west coast and flooded inland. The series can also be used to see how Utah would be impacted by global sea level rise.

NOTE: The highest tsunami recorded was 1720 feet in Lituya Bay, Alaska.
