Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Moekeshiwan [Lvinaya Past]
The Moekeshiwan caldera is seen here from the west with its NW rim at the right and the E rim on the left horizon. The 7 x 9 km caldera on southern Iturup Island formed about 9,400 years ago during one of the largest Holocene eruptions of the Kuril Islands.

The rim of the 7 x 9 km Moekeshiwan [Lvinaya Past] caldera on southern Iturup Island drops to 50 m below sea level on the NW side. Lvinaya Past, meaning Lion's Jaw, derives 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 NW side allows 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. The caldera formed about 9,400 years ago, depositing thick dacitic pumice deposits that form the 50-60 m high Yuzhny (Southern) isthmus, which joins the southernmost volcanoes on Iturup Island.
