Photo Gallery

Ulreung volcano, also known as Ullung, forms a small 10-km-wide island in the Sea of Japan about 100 km east of the coast of the central Korean Peninsula. The island, seen in this NASA Landsat image (with north to the top) is a tourist destination from the Korean mainland. The 984-m-high stratovolcano is truncated by a caldera. Ulreung was the site of a major explosive eruption at the beginning of the Holocene that produced pyroclastic flows and deposited ash across the Sea of Japan in central Honshu.
