The white swirls in this image are Kármán vortices, or fluid perturbations, that formed over the southern Kuril Islands of Broutona, Chirpoy, and Brat Chirpoyev in the Sea of Okhotsk. In this Landsat 7 image from 2000, the spiral chains and vortices are formed by the airflow being perturbed by the islands. Located in the northwest Pacific Ocean between the southern tip of Russia’s Kamchatka Peninsula and the Japanese island of Hokkaido, the Kuril Islands are a part of the geological formation known as the Greater Kuril Ridge, which developed over the last 90 million years.
