2011 Burma March 25 earthquake location

The Daen Lao Range (Thai: ทิวเขาแดนลาว, pronounced [tʰīw kʰǎw dɛ̄ːn lāːw]; Burmese: Loi La) is a mountain range of the Shan Hills in eastern Burma and northern Thailand. Most of the range is located in Shan State, with its northern limit close to the border with China, and runs southwards across the Thai border, at the northern end of Thailand.

Geologically in the Daen Lao Range, as in the other southern subranges of the Shan Hills, layers of alluvium are superimposed on hard rock.

Geography

The range extends east of the Salween until almost reaching the Golden Triangle area, separating the Salween watershed from the Mekong watershed. At its southern end the Thanon Thong Chai Range (เทือกเขาถนนธงชัย) subrange stretches further southwards into Thailand between the Sai River in the east and the Pai River in the west; the latter separating the Daen Lao from the Thanon Thong Chai Range. Some geographers include the Thanon Thong Chai Range subrange as part of the Daen Lao Range. The Khun Tan Range also extends southwards from the Daen Lao Range, parallel to the Thanon Thong Chai mountains, but it differs geologically and structurally from the latter.

The name "Lao" in the range name is a Thai Yuan word possibly not related to the Lao country. The western end of the range is not clearly defined. Altitudes range between 400–2,500 m. The highest point is 2,563 m Loi Pangnao in Burma, with a prominence of 1,596 m, one of the ultra prominent peaks of Southeast Asia. On the Thai side the highest point is 2,285 m Doi Pha Hom Pok. Doi Chiang Dao (2,175 m), Doi Puk Phakka (1,794 m), Doi Nang Non, a karstic formation in Chiang Rai Province, Doi Tung, Doi Ang Khang and Doi Wao, where Wat Doi Wao is located, as well as the mountains surrounding the village of Santikhiri (Doi Mae Salong) are also part of this range.

History

Historically the area has been sparsely populated. Only some hill tribes such as the Wa, Akha, Yao, Lahu and the Lisu people lived in scattered small villages across the range.

In 1605 King Naresuan of Ayutthaya marched his armies across the Daen Lao Range to rescue the Shan King of Hsenwi, but he died during his journey across the mountains. Many Shan people believe King Naresuan was cremated in the Daen Lao Range, in the southern part of the Shan State, and his ashes interred in a stupa in Mongton.

Until the 1990s one of the main crops at altitudes above 1,000 m was opium. On the side of the range controlled by the Thai government, construction of roads reaching remote areas and increasingly efficient policing ensured a measure of success of the opium replacement programs in recent years.

Owing to the unrest in Burma, the National Democratic Alliance Army (NDAA) and other groups seek a refuge and a base for their insurgency in these lonely mountains. Fighting and the ensuing persecution by the Tatmadaw have caused part of the original population to flee. Some refugee camps have been established for cross-border refugees in the Thai side of the range. Some Kayah and Karen communities, like the "long-necked Karen", are regularly visited by organized tourist groups.

The Ang Khang Royal Agricultural Station is located amidst the mountains of the range. It was founded in 1969 by the King of Thailand and is noted by its temperate climate that allows the cultivation of flowers and fruits characteristic of colder climates.

In March 2011 there was a magnitude 5 earthquake in the Burmese side of the range with the epicenter north of Chiang Rai town. There were over 70 deaths and more than hundred wounded.
