摘要

描述
English: Natural-colour image of Shikotan. The island is surrounded by sea ice—swirling shapes of ghostly blue-gray. The ice in this image may have formed in a matter of several days, and it is prone to moving with currents. North of the western end of Shikotan, eddies have shaped the ice into rough circles. The eddies may result from opposing winds—winds from the north pushing the ice southward, and winds from the south-west pushing the ice toward the north-east. Uneven snow cover exaggerates the island’s rugged appearance. Multiple forces have shaped Shikotan over millions of years. Geologic studies indicate that it has been battered by multiple tsunamis, although wind, rain, and tectonic forces likely play a greater role in shaping the surface. Part of the Pacific Ring of Fire, the island is seismically active.
