Iturup Island, belonging to the southern Kuril Islands, but disputed by Russia and Japan, runs diagonally across this  orthorectified image between the Sea of Okhotsk (left) and the North Atlantic Ocean (right). A chain of volcanic massifs stretches northeast to southwest along the length of the island.

Here, from bottom to top,  are the Berutarube stratovocano (at the tip of the island), the submerged caldera rim of the Lvinaya Past volcano, the Atsonupuri stratovolcano (west coast), the Bogatyr Ridge stratovolcano (center), the Grozny Group complex volcano (just northeast of the bay on the east coast), and the Baransky stratovolcano (near the east coast, just northeast of the previous).

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.

Iturup is the largest and northernmost island of the South Kuril Islands. It is presently controlled by Russia, although it is also claimed by Japan.

Iturup is located near the southern end of the Kuril chain, between Kunashir (19 km to the southwest) and Urup (37 km to the northeast). It has an area of 3,139 km², a length of 200 km and a width that ranges from 7 to 27 km. This image focuses on the central and northern parts of the island.

Iturup consists of volcanic massifs and mountain ridges, whose contours are clearly visible in this orthorectified image. A series of a dozen volcanoes running northeast to southwest form the backbone of the island, the highest being Stokap (1,634 m) in the central part of Iturup. The shores of the island are high and abrupt.
