Japan's search for the disappearance of the North Island and the reduction of Japan's territorial sea
4hw.com.cn: sea level rise is no longer a new topic. Japan's land area is small, and there are affiliated small islands around it that often disappear. Recently, Japan began to search for the disappeared Bibei island. Let's see the details below.
According to Japanese media htbnews reported on the 20th, Japan's Maritime Security Agency recently began a field investigation on the suspected disappearance of 'esanbe nose North Island' in the north of Hokkaido.
It is reported that the island is located in the open sea about 500 meters away from Houfu village, Hokkaido. According to the survey in 1987, the island is about 1.4 meters above the sea level, but in the autumn of 2018, the island 'disappeared out of thin air'. Some villagers said that the last time they saw the island was five or six years ago.
Japan's maritime security agency attaches great importance to the height of the island above sea level. If it is submerged at high tide, the island cannot be recognized as an 'island'; If there is only a part that surfaced at low tide, the island can also be recognized as a 'low tide highland' as the base point of the territorial sea. However, if the island is still missing at low tide, Japan's territorial waters will 'shrink'. It is understood that ice erosion may be the main reason for the disappearance of the island& lsquo;& rsquo;
