Geograph
Jeju Island is a volcanic island, dominated by Halla-san (Halla Mountain): a volcano 1,950 metres (6,400 ft) high and the highest mountain in South Korea. The island measures approximately 73 kilometres (45 mi) across, east to west, and 41 kilometres (25 mi) from north to south.
The island was created entirely from volcanic eruptions approximately 2 million years ago, during the time period extending from the Tertiary to the beginning of the Quaternary period, and consists chiefly of basalt and lava. The eruptions took place in the Cenozoic era. It has a humid subtropical climate, warmer than that of the rest of Korea, with four distinct weather seasons. Winters are cool and dry while summers are hot, humid, and sometimes rainy.


There is a crater lake which is the only crater lake in South Korea.
An area covering about 12% (224 square kilometres or 86 square miles) of Jeju is known as Gotjawal Forest. This area remained uncultivated until the 21st century, as its base of ʻAʻā lava made it difficult to develop for agriculture. Because this forest remained pristine for so long, it has a unique ecology. The forest is the main source of groundwater and thus the main water source for the half millon people of the island, because rainwater penetrates directly into the aquifer through the cracks of the ʻAʻā lava under the forest. Gotjawal forest is considered an internationally important wetland under the Ramsar Convention by some researchers because it is the habitat of unique species of plants and is the main source of water for the residents, although to date it has not been declared a Ramsar site.

Administrative divisions

Modern

Japan took Korea over forcefully in 1910. In 1915 the gun or county system which had been adopted in 1906 was abolished and Jeju island was designated as part of the 'island' system and called Jeju myeon under South Jeolla province. In 1931, Jeju-myeon was raised to the status of Jeju-eup or 'township' which gave the island one township (today's Jeju-si area) and 12 'myeon'.
On September 1, 1955, Jeju Township was elevated to city status with 40 administrative wards which on January 1, 1962, were reduced to 14 wards. On July 8, 1956, Seogwi, Daejeong and Hallim-myeons were raised to the status of townships while the southwestern portion of Hallim Township was separated and newly designated as the Hankyeong district(myeon) which gave the province one city, two counties, three townships and 10 myeon or districts with 14 wards in Jeju City. May 23, 1979 saw the restructuring of the Jeju-si wards and the addition of three more, giving 17 wards.

Current

Until 2005, Jeju Province was divided into two cities (si), Jeju and Seogwipo, and two counties (gun), Bukjeju (North Jeju) and Namjeju (South Jeju) respectively. The two cities were further divided into thirty-one neighbourhoods (dong), while the two counties were divided into seven towns (eup) and five districts (myeon). The seven towns and five districts were in turn divided into 551 villages (ri).
In 2005, Jeju residents approved, by referendum, a proposal to merge Bukjeju County into Jeju City, and Namjeju County into Seogwipo City. Effective 1 July 2006, the province was also renamed Jeju Special Autonomous Province with two nominal subdivisions, Jeju City and Seogwipo City. In addition to the changes in name, the province was given extensive administrative powers that had previously been reserved for the central government. This is part of plans to turn Jeju into a "Free International City".
Jeju, on 1 July 2006, was made into the first and only special autonomous province of South Korea
