Crescent City
The topography of the sea floor surrounding Crescent City has the effect of focusing tsunamis. According to researchers at Humboldt State University and the University of Southern California, the city experienced tsunami conditions 31 times between the years 1933 and 2008. Although many of these incidents were barely perceptible, eleven events included wave measurements exceeding one meter, four events caused damage, and one event in particular is commonly cited as "the largest and most destructive recorded tsunami to strike the United States Pacific Coast."
