Sumisu Island (須美寿島, Sumisu-tō) is a volcanic, deserted island located in the Philippine Sea approximately 110 kilometres (68 mi) off the coast of Aogashima, near the southern end of the Izu archipelago, Japan. Sumisu-tō is administratively part of Tokyo Metropolis.
The island is a basalt and olivinepillar with sheer sides, the only visible portion of an active submarine volcanic caldera extending south of the island with a circumference of approximately 10 kilometres (6.2 mi). The above sea-level portion has a height of 134 metres (440 ft). The island is estimated to have been created by a volcanic eruption around 20,000 years ago. In the immediate vicinity are numerous exposed and awash rocks. Due to its shape and heavy seas it is difficult to disembark on the island, although at times fishermen are known to have landed. The abundance of fish in the surrounding waters have made it attractive for both sport and commercial fishing.
Historyedit
The island has been known by Japanese fishermen and mariners from an early time. In 1870, a submarine eruption was recorded NNE of the island, resulting in the formation of a new islet, named Niijima (新島), with a height of 13 metres (43 ft). The islet has subsequently sunk beneath sea level due to erosion. From 1974 to 1977, a series of underwater eruptions have been recorded, discoloring water in the area. In November 1991, a fishing vessel reported that a large section of the island's northern face had collapsed, resulting in a significant change in its profile. Further changes to the island's profile were recorded after 1992 earthquakes.
