On April 26, the Ministry of Natural Resources released the "Survey Report on the Topography and Geomorphology of the Diaoyu Island and its Affiliated Islands" on its official website and the Diaoyu Island special website.
The survey results show that the Diaoyu Island belongs to the erosion and denudation of low hills with steep terrain. The ridge line of the central mountain ranges from east to west, connecting the main peak Gaohua Peak (362 meters above sea level) and Shennong Peak (320 meters above sea level). It is located in the central and southern part of the island, forming a slightly northern slope. The topographic pattern of gentle, steep south slope.
There is a relatively wide shallow sea area near the Diaoyu Island, especially near Dongdiaojiao, where a wide underwater shoal develops and is connected with the shoals around Feiyu Island.
The survey results show that Beixiaodao is an eroded and denuded hilly landform with large topography. The coast type is a bedrock coast with strong sea erosion. There are sea erosion landforms such as sea erosion cliffs, sea erosion platforms, and sea erosion pillars.
The Lion Peak (118 meters) in the southeast of Beixiao Island and its northwestern Yingfeng (125 meters), Lianhua Rock (62 meters) and Kong Mingshi (62 meters) are three independent sharp rocks, which are connected by a sea erosion platform.
The olive gate between the North Island and the South Island is about 10 meters deep and 200 meters wide.
The coastal shallow waters of the two islands are connected together, narrow on the southwest side, and wide on the northeast side for nearly 2 kilometers, in which a series of tidal trenches are distributed.
According to the report, the South Island is an eroded and denuded hilly landform with an overall elliptical shape. It is formed by connecting the island’s main body Jiantou Ridge and a sharp rock in the southeast-Thumb Peak, via a sea erosion platform.
The terrain is high in the northwest and southeast, and low in the middle.
The report pointed out that by systematically sorting out historical long-term survey data, combined with the latest high-resolution satellite remote sensing survey results, continuously tracking and mastering the submarine topography and geomorphology of the Diaoyu Island and its affiliated islands, further supplementing and improving the basic geographic data system of the Diaoyu Island and its affiliated islands. It plays an important supporting role in resource management and ecological protection of the Diaoyu Islands.
