The Republic of Korea shares the Korean Peninsula with North Korea (the People's Republic of Korea) to the North. South Korea occupies 99,237 square kilometers, about 45 percent of the whole of Korea and is slightly larger than Hungary, but a little smaller than Iceland in comparison. Its neighbors are China to the West, Japan to the East and Russia to the North.

The peninsula extends southward from eastern Manchuria and Siberia and well into Kyushu, Japan's major southern island. The northern border of the peninsula extends along the boundary of China (Manchuria) and touches Russia to the east, just 75 miles away from Vladivostok, Russia's major eastern port city. The northern border is mainly formed by two large rivers - the Amnokkang that flows westward into the Yellow Sea; the Tumangang that flows into the East Sea.

About 70% of Korea is mountainous, mainly to the north and east, causing a great variation in rainfall and temperature between winter and summer. Only 22% of the land can be farmed because of its mountainous being. Korea has four obvious distinct seasons: a wet monsoon/summer in the middle of the year; a very cold winter towards the end of the year (November to March). The warmest and wettest place in the country is Cheju-do, off the south coast.

Korea was exploitatively logged and mined during the Japanese reign. However, Korea has now reforested a large area of its country. The northern Korea is now covered with alpine, where you can find beech, fir and pine trees in abundance and it is the only part of the country where you are able to see black bears and deer. Trailing down the south coast, everything gets more tropical and vegetation is of prime activity. This is where ginseng supplies (for Korea and outside world) come from. Korea is also surrounded with 20 national parks, namely Soraksan (the most popular one to date), Hallasan and Chirisan parks.

The peninsula is located mid-latitude in the nothern hemisphere and lies in the transitional zone between continental and subtropical maritime climates. It has four distinct seasons.

The north to south geography of the peninsula produces climatic differences aling its length. In the south, spring and summer are normally longer, while the north, autumn and winter are longer.

Background: At the end of World War II, the US and the Soviet Union agreed that US troops would accept the surrender of Japanese forces south of the 38th parallel and the Soviet Union would do so in the north. In 1948, the UN proposed nationwide elections; after P'yongyang's refusal to allow UN inspectors in the north, elections were held in the south and the Republic of Korea was established.

The Democratic People's Republic of Korea was established the following month in the north. Communist North Korean forces invaded South Korea in 1950. US and other UN forces intervened to defend the South and Chinese forces intervened on behalf of the North.

After a bitter three-year war, an armistice was signed in 1953, establishing a military demarcation line near the 38th parallel.

Thereafter, South Korea achieved amazing economic growth, with per capita output rising to 13 times the level in the North. Since late 1997, however, the nation has suffered widespread financial and organizational difficulties. Continuing tensions between North and South have raised concerns of provocative military actions by the North.

Following World War II, a republic was set up in the southern half of the Korean Peninsula while a communist government was installed in the north.

Between 1950 and 1953, US and other UN forces intervened to defend South Korea from North Korean attacks supported by the Chinese; an armistice was signed in 1953.

Thereafter, South Korea achieved amazing economic growth, with per capita income rising to 13 times the level of North Korea. In 1997, the nation suffered a severe financial crisis from which it continues to make a solid recovery.

South Korea has also maintained its commitment to democratize its political processes.

Land Area and Borders

The Korean Peninsula extends for about 1,000 kilometers southward from the northeast part of the Asian continental landmass. The Japanese islands of Honshu and Kyushu are located some 200 kilometers to the southeast across the Korea Strait; the Shandong Peninsula of China lies 190 kilometers to the west. The west coast of the peninsula is bordered by the Korea Bay to the north and the Yellow Sea to the south; the east coast is bordered by the Sea of Japan (known in Korea as the East Sea). The 8,640- kilometer coastline is highly indented. Some 3,579 islands lie adjacent to the peninsula. Most of them are found along the south and west coasts.

The northern land border of the Korean Peninsula is formed by the Yalu and Tumen rivers, which separate Korea from the provinces of Jilin and Liaoning in China. The original border between the two Korean states was the thirty-eighth parallel of atitude. After the Korean War, the Demilitarized Zone (DMZ-- ) formed the boundary between the two. The DMZ is a heavily guarded, 4,000-meter-wide strip of land that runs along the line of cease-fire, the Demarcation Line , from the east to the west coasts for a distance of 241 kilometers (238 kilometers of that line form the land boundary with North Korea).

The total land area of the peninsula, including the islands, is 220,847 square kilometers. Some 44.6 percent (98,477 square kilometers) of this total, excluding the area within the DMZ, constitutes the territory of the Republic of Korea. The combined territories of North Korea and South Korea are about the same size as the state of Minnesota. South Korea alone is about the size of Portugal or Hungary, and is slightly larger than the state of Indiana.

The largest island, Cheju, lies off the southwest corner of the peninsula and has a land area of 1,825 square kilometers. Other important islands include Ullung in the Sea of Japan and Kanghwa Island at the mouth of the Han River. Although the eastern coastline of South Korea is generally unindented, the southern and western coasts are jagged and irregular. The difference is caused by the fact that the eastern coast is gradually rising, while the southern and western coasts are subsiding.

Lacking formidable land or sea barriers along its borders and occupying a central position among East Asian nations, the Korean Peninsula has served as a cultural bridge between the mainland and the Japanese archipelago. Korea contributed greatly to the development of Japan by transmitting both Indian Buddhist and Chinese Confucian culture, art, and religion. At the same time, Korea's exposed geographical position left it vulnerable to invasion by its stronger neighbors. When, in the late nineteenth century, British statesman Lord George Curzon described Korea as a "sort of political Tom Tiddler's ground between China, Russia, and Japan," he was describing a situation that had prevailed for several millennia, as would be tragically apparent during the twentieth century.

Topography and Drainage

Early European visitors to Korea remarked that the land resembled "a sea in a heavy gale" because of the large number of successive mountain ranges that crisscross the peninsula. The tallest mountains are in North Korea. The tallest mountain in South Korea is Mount Halla (1,950 meters), which is the cone of a volcanic formation constituting Cheju Island. There are three major mountain ranges within South Korea: the T'aebaek, and Sobaek ranges, and the Chiri Massif .

Unlike Japan or the northern provinces of China, the Korean Peninsula is geologically stable. There are no active volcanoes and there have been no strong earthquakes. Historical records, however, describe volcanic activity on Mount Halla during the Koryo Dynasty (918-1392 A.D.).

Over the centuries, Korea's inhabitants have cut down most of the ancient Korean forests, with the exception of a few remote, mountainous areas. The disappearance of the forests has been a major cause of soil erosion and flooding. Because of successful reforestation programs and the declining use of firewood as a source of energy since the 1960s, most of South Korea's hills in the 1980s were amply covered with foliage. South Korea has no extensive plains; its lowlands are the product of mountain erosion. Approximately 30 percent of the area of South Korea consists of lowlands, with the rest consisting of uplands and mountains. The great majority of the lowland area lies along the coasts, particularly the west coast, and along the major rivers. The most important lowlands are the Han River plain around Seoul, the Pyongt'aek coastal plain southwest of Seoul, the Kum River basin, the Naktong River basin, and the Yongsan and the Honam plains in the southwest. A narrow littoral plain extends along the east coast.

The Naktong is South Korea's longest river (521 kilometers). The Han River, which flows through Seoul, is 514 kilometers long, and the Kum River is 401 kilometers long. Other major rivers include the Imjin, which flows through both North Korea and South Korea and forms an estuary with the Han River; the Pukhan, a tributary of the Han that also flows out of North Korea; and the Somjin. The major rivers flow north to south or east to west and empty into the Yellow Sea or the Korea Strait. They tend to be broad and shallow and to have wide seasonal variations in water flow.

News that North Korea was constructing a huge multipurpose dam at the base of Mount Kumgang (1,638 meters) north of the DMZ caused considerable consternation in South Korea during the mid1980s . South Korean authorities feared that once completed, a sudden release of the dam's waters into the Pukhan River during north-south hostilities could flood Seoul and paralyze the capital region. During 1987 the Kumgang-san Dam was a major issue that Seoul sought to raise in talks with P'yongyang. Though Seoul completed a "Peace Dam" on the Pukhan River to counteract the potential threat of P'yongyang's dam project before the 1988 Olympics, the North Korean project apparently still was in its initial stages of construction in 1990.

South Korea


Part of the East Asian monsoonal region, South Korea has a temperate climate with four distinct seasons. The movement of air masses from the Asian continent exerts greater influence on South Korea's weather than does air movement from the Pacific Ocean. Winters are usually long, cold, and dry, whereas summers are short, hot, and humid. Spring and autumn are pleasant but short in duration. Seoul's mean temperature in January is -5° C to - 2.5° C; in July the mean temperature is about 22.5° C to 25° C. Because of its southern and seagirt location, Cheju Island has warmer and milder weather than other parts of South Korea. Mean temperatures on Cheju range from 2.5° C in January to 25° C in July.

The country generally has sufficient rainfall to sustain its agriculture. Rarely does less than 75 centimeters of rain fall in any given year; for the most part, rainfall is over 100 centimeters. Amounts of precipitation, however, can vary from year to year. Serious droughts occur about once every eight years, especially in the rice-producing southwestern part of the country. About two-thirds of the annual precipitation occurs between June and September.

South Korea is less vulnerable to typhoons than Japan, Taiwan, the east coast of China, or the Philippines. From one to three typhoons can be expected per year. Typhoons usually pass over South Korea in late summer, especially in August, and bring torrential rains . Flooding occasionally causes considerable damage. In September 1984, record floods caused the deaths of 190 people and left 200,000 homeless. This disaster prompted the North Korean government to make an unprecedented offer of humanitarian aid in the form of rice, medicine, clothes, and building materials. South Korea accepted these items and distributed them to flood victims.
