Sumisu-jima ( Japanese 須 美 寿 島 , also: Sumisu-tō ), also known as Smith Island or Smith Rock , is a small, uninhabited rock island of volcanic origin in the Pacific Ocean . It is the third southernmost island of the Japanese Izu Islands .
administration
Like the entire chain of Izu Islands, Sumisu-jima belongs administratively to Tokyo Prefecture . They are part of the Hachijō sub-prefecture, which is administered from Hachijō-jima . However, like the three Izu Islands Bayonnaise Rocks , Torishima and Sōfugan, they do not belong to any municipality and are therefore de facto a municipality-free area . They are claimed by the communities of Aogashima and Hachijō .
geography
Sumisu-jima is located about 520 km south of Tokyo and 110 km north of the neighboring island of Torishima . The elongated rock protruding almost vertically from the ocean has an area of 0.02 km² and reaches a height of 136 m above sea level.
The island represents the southern edge of a submarine caldera with a diameter of eight to nine kilometers, which lies above the sea surface . The last eruption occurred in 1916. Since the 1970s, discoloration of the water near Sumisu-jima has been observed frequently.
