The Effect of the Earth’s Rotation on Tsunami Waves Triggered by the 2013 Deep-Focus Okhotsk Sea Earthquake

Аннотация

The features of the dynamics of weak tsunami waves caused by the deep-focus Okhotsk Sea earthquake on May 24, 2013, are studied with numerical modeling. It is found that the vast area of coseismic deformations along with the shallow depth of the Sea of Okhotsk and high latitudes were favorable for effects of the Earth’s rotation in the dynamics of the 2013 Okhotsk Sea tsunami. The comparison of calculations with and without the Coriolis force showed that the Earth’s rotation significantly affects the wave field, changing the wave forms and the distribution of the maximum amplitudes.
