Map showing aftershock zones of great Aleutian Islands earthquakes in the 20th century

Map showing aftershock zones of great Aleutian Islands, Alaska, earthquakes in the 20th century. Red solid line with pink fill indicates aftershock zone of the 1957 Aleutian Islands earthquake from Sykes et al. (1980), with the red dotted line indicating the relocated aftershock zone from Tape and Lomax (2022). Blue bars denote observed maximum runup from the resulting tsunami compiled by Nicolsky et al. (2016). Red dashed lines delineate relocated aftershock zones of the 1946 Aleutian Islands tsunami earthquake and the 1965 Rat Islands earthquake (Tape and Lomax, 2022). Arrows and labels indicate Pacific plate convergence direction and rate relative to a fixed North American/Bering Sea plate.
