Demiliterized Zone (DMZ), Korea.

I went to Demiliterized Zone (DMZ) during I visited to Seoul at February 2010.This demarcation exist after Korean War.
DMZ is a symbol of ideological dispute between North and South Korea, winds 155 miles across the Korean Peninsula. Stretching from the Han River to the East Coast, it ranges 2 km north and south of the Military Demarcation Line, covering a vast region of 64 million sq. ft. Devoid of people, rare plants and animals exist in an unnatural nature preserve.



In DMZ, found four tunnels. North Korea began digging tunnels under the DMZ at the same time that the South and the North first launched peace talks in 1974.

1st Infiltration Tunnel
The first tunnel was discovered in November 1974, in the Western Sector of the DMZ near Gorang-po. With an estimated total length of 3.5 kilometers, it extends one kilometer south of the Military Demarcation Line that divides the DMZ. The walls and ceiling of the tunnel, 1.2 meters high and 0.9 meters wide, are reinforced with concrete slabs. It has the capacity to move an entire regiment per hour through it.



2nd Infiltration Tunnel
Twice as wide as the first tunnel, the second tunnel was discovered in March 1975 in the Central Sector of the DMZ, about 13 kilometers north of Cheorwon. Measuring two meters high and 2.1-2.2 meters wide, the arch-shaped tunnel is large enough to move heavy weapons as tanks, field artillery, and armored personnel carriers. More than 30,000 troops could move, three to four abreast (a division in strength), per hour.

The 3rd Infiltration Tunnel
Only 44 kilometers from Seoul (less than an hour's drive), the third tunnel was discovered in October 1978. Almost identical in structure to Tunnel 2, the 1.635 kilometer-long tunnel is 1.95 meters high and 2.1 meters wide. It penetrates 435 meters south of the Military Demarcation Line at a point 4 kilometers south of Panmunjeom, running through bedrock at a depth of about 73 meters below ground. Capable of moving a full division (plus their weapons) per hour, it was evidently designed for a surprise attack on Seoul.

The 4th Infiltration Tunnel
The fourth tunnel, which is located along one of the most strategic routes in the Eastern Sector, was discovered in March 1990 only 26 kilometers northeast of Yanggu.




at this moment after independent team proving North Korea Torpedo's (Cheonan corvette in March) sinking the South Korean ship killing 46 sailors -- the deadliest military incident since the Korean War.
North Korea and south Korea have hard tension.



but from North Korea side: North Korea has repeatedly denied responsibility for the Cheonan incident. The official Korean Central News Agency said on Saturday the United States was blaming the North for the ship sinking in order to keep a U.S. Marine base in Japan and make China feel "awkward."



I hope there are peaces forever in DMZ.
