Key Points:
- We present earthquake recurrence estimates from geologic and geodetic
data for the Alaska-Aleutian subduction zone
- Recurrence estimates provide constraints for seismic hazard models
- The recurrence estimates indicate that the rates of Mw≥ 8 ruptures are higher than previously inferred west of Kodiak
Island
