Ulleungdo's Neighboring Island of Jukdo (죽도 - 竹島)

Jukdo (竹島 - 죽도) is a small 51-acre island about two kilometers off the east shore of Ulleungdo (鬱陵島 - 울릉도). During Korea's Joseon period, it was referred to as Usando (于山島 - 우산도). Many people, including Koreans, are confused by the fact that the Chinese characters used for "Jukdo" (竹島) are the same as those used for the Japanese island of "Takeshima" (竹島), which Koreans call "Dokdo" (獨島 - 독도) and people in the West call "Liancourt Rocks." The names are different because the characters are pronounced differently in the two languages. Koreans claim that Usando (우산도 - 于山島) was the old Korean name for "Dokdo" (Liancourt Rocks / Takeshima), but Korea's old maps show that Usando was simply Ulleungdo's neighboring island of Jukdo, not Liancourt Rocks, which are about ninety-two kilometers southeast of Ulleungdo.

Compare the shape and location of Jukdo (竹島 - 죽도) from Google's satellite photo with the shape and location of the neighboring island labeled as "Usan" (于山 - 우산) on some of Korea's old maps of Ulleungdo (鬱陵島 - 울릉도):
"Haedong Yeojido" (海東輿地圖) - Ulleungdo (울릉도 - 鬱陵島) ca. 1776 - 1795

"Dong Yeodo" (東輿圖) - Ulleungdo (울릉도 - 鬱陵島), 1795 - 1800
"Joseon-do" (朝鮮圖) - Ulleungdo (울릉도 - 鬱陵島), 1800 - 1822
Cheonggu-do (靑邱圖) - Ulleungdo (鬱陵島 - 울릉도) 1834
On the above Cheonggu-do (靑邱圖) map of Ulleungdo, the hash marks along the edge of the map represented distances of 10 ri, which was four kilometers and sometimes seem to have represented two kilometers. Ulleungdo's neighboring island of Jukdo is about two kilometers off its east shore. Liancourt Rocks (Dokdo / Takeshima), on the other hand, is about 92 kilometers southeast of Ulleungdo, which means the neighboring island labeled as "Usan" (于山 - 우산) on the above maps could not have been Dokdo (獨島 - 독도).
The following is the satellite photo of Ulleungdo's neighboring island of Jukdo overlayed with an image of the island labeled as "Usan" (于山) on the 1834 Cheonggu-do (靑邱圖) map.

    See this video and you can understand Jukdo's geography which have small mountain on north.
