Шаблон:Nihongo is a group of volcanic rocks in the Philippine Sea about Шаблон:Convert south of Tokyo and Шаблон:Convert south-southeast of Aogashima, in the south portion of the Izu archipelago, Japan. The rocks were discovered by the French corvette Bayonnaise in 1850, while surveying the islands south of Tokyo Bay.[1]
Geography
The rocks are the exposed portion of the western ridge of a submarine volcanic caldera, approximately Шаблон:Convert in diameter at a depth of approximately Шаблон:Convert.[2] The above sea-level portion has a surface area of approximately 0.01 square kilometers, with a summit height of Шаблон:Convert. and consists of three large rocks and many smaller rocks.[1]
The caldera is known to have erupted in 1869–1871, 1896, 1906, 1915, 1934, 1946, 1952–1955, 1957–1960, 1970, and 1988. The last known submarine eruption of the caldera was in 2023, which discolored the local water.[3]
On the northeast rim of the same caldera Шаблон:Convert to the east of the Bayonnaise Rocks is a submerged reef named Шаблон:Nihongo, which is a post-caldera cone with a depth of approximately Шаблон:Convert. During a submarine volcanic eruption of 17 September 1952, an ephemeral island was formed, with a height of Шаблон:Convert, which was created and destroyed several times by volcanic activity until completely disappearing on 23 September 1953. The following day, an eruption killed 31 researchers and crewmen aboard the Maritime Safety Agency survey ship No.5 Kaiyo-Maru. The island reappeared on 11 October, sinking again on 11 March 1954 and reappeared one more time between 5 April and 3 September 1954.[1]
Vegetation is sparse among the Bayonnaise Rocks. The islands are a resting place for migratory birds. Located in the Kuroshio Current, the area has abundant sea life, and is popular with sports fishermen.
