Lvinaya Past and Other Volcanoes of Southern Iturup Island44.6N 146.9E
The topography of Iturup, the largest of the southern Kuril Islands, disputed by Russia and Japan, includes a chain of volcanic massifs running northeast to southwest. This image focuses on the volcanoes on the southern part of the island.
The most distinctive is the Lvinaya Past (literally “Lion’s Jaw”) volcano, located on the western shore. The volcano derives its name from a rock resembling a sleeping lion that breaches the surface at the center of the submerged caldera rim.
A shallow 5-km-wide passageway on the northwest side allows access of the Sea of Okhotsk into the caldera basin, whose floor is 550 m below sea level and lies almost 1 km below the caldera rim. From above, the caldera looks like a circular bay on the west coast.
Also visible in this orthorectified image are Berutarube and Atsonupuri, both stratovolcanoes. The former is seen here at the very tip of the island, while the latter is located on a peninsula on the west coast near the top of the image.
