Abstract On January 23, 2018, a 7.9-magnitude earthquake occurred in the gulf of Alaska. The Okada model is used to calculate the initial tsunami field information, and the COMCOT model is used to simulate the tsunami propagation. The simulated amplitude and arrival time of the tsunami wave are compared with the measurements at the DARTs station. The amplitude difference is within 4 cm, and the time difference is within 4 minutes; furthermore, the simulation results agree with the measurements, which reveals that the intensity of the tsunami caused by the Alaska earthquake is weak and reflects that the selection of the parameters of the initial tsunami field is reasonable and effective. Also, the results of tsunami simulation are reliable.
