The Three Pagodas Fault is a right-lateral displacement strike-slip fault between Burma and Thailand named after the Three Pagodas Pass. It developed as a consequence of the collision between the Indian and the Eurasian Plate. [1] The Three Pagodas Fault Zone (TPFZ) is a roughly 50 km wide zone separating the westernmost range of the Tenasserim Hills from the Tenasserim coast in Myanmar. The whole area is marked by a great number of fault traces and homoclinal ridges of Paleozoic limestone. [2]
The Three Pagodas Fault Zone accommodates the southeastward extrusion of Indochina, with stresses twisting clockwise. Together with the Wang Chao Fault and the Mae Ping Fault, [3] it runs parallel to the Red River Fault. There is a fear that a future earthquake caused by the TPFZ and the Sri Sawat Fault Zone (SSFZ) could damage the large dams in Kanchanaburi Province in the future and that it could cause widespread damage to Bangkok. There was already a severe earthquake in the area about 2,500 years ago. [4]
Kanchanaburi is the largest of the western provinces (changwat) of Thailand. The neighboring provinces are Tak, Uthai Thani, Suphan Buri, Nakhon Pathom, and Ratchaburi. In the west it borders Kayin State, Mon State, and the Tanintharyi Region of Myanmar.
Three Pagodas Pass is a pass in the Tenasserim Hills on the border between Thailand and Myanmar (Burma), at an elevation of 282 metres (925 ft). The pass links the town of Sangkhla Buri in the north of Kanchanaburi Province, Thailand, to the town of Payathonsu in the south of Kayin State, Myanmar.
Dawei is a city in south-eastern Myanmar and is the capital of the Tanintharyi Region, formerly known as the Tenasserim Division, on the northern bank of the Dawei River. The city is about 614.3 km (381.7 mi) southeast of Yangon. Its population is 146,964. Dawei is a port at the head of the Dawei River estuary, 30 km (18.6 mi). from the Andaman Sea. As a result, the city is prone to flooding during the monsoon season. "Dawei" is also the name of one of Myanmar's 135 ethnic minorities.
The Thung Yai Naresuan Wildlife Sanctuary is a protected area in Thailand in the northern part of Kanchanaburi Province and the southern part of Tak Province. It was declared a wildlife sanctuary in 1972, and a World Heritage Site by UNESCO in 1991 together with the adjoining Huai Kha Khaeng Wildlife Sanctuary.
Western Thailand is a region of Thailand bordering Myanmar on the west, Southern Thailand on the south, and central Thailand on the east.
The Burmese–Siamese War (1785–1786), known as the Nine Armies' Wars in Siamese history because the Burmese came in nine armies, was the first war between the Konbaung dynasty of Burma and the Siamese Rattanakosin Kingdom of the Chakri dynasty.
The Tha Din Daeng campaign was a short conflict, occurring in 1786 in Tha Din Daeng, now in Kanchanaburi Province in western Thailand. The belligerents were King Bodawpaya of the Burmese Konbaung Dynasty, against Phraphutthayotfa Chulalok and Maha Sura Singhanat of the Rattanakosin Kingdom.
The Tenasserim Hills or Tenasserim Range is the geographical name of a roughly 1,700 km long mountain chain, part of the Indo-Malayan mountain system in Southeast Asia.
Myanmar–Thailand relations refers to the current and historical relations between Myanmar and Thailand. Myanmar has an embassy in Bangkok. Thailand has an embassy in Yangon. Relations between Burma and Thailand focus mainly on economic issues and trade. There is sporadic conflict with Thailand over three disputed islands.
Mae Chan Fault is an active 118 km long west-southwest–east-northeast trending left lateral strike-slip fault in Northern Thailand that extends into western Laos. It was responsible for a 6.3 magnitude quake in Laos on May 16, 2007, that caused property damage as far as Chiang Rai in Thailand. A part of it stretches from Mae Chan to Mae Ai for 40 km along the highway, then goes through Fang, Chiang Dao, Mae Rim and San Kamphaeng districts of Chiang Mai, to Mae Tha district of Lamphun.
A Mw 6.8 earthquake occurred on 24 March 2011 in Shan State, Myanmar. It had an epicenter northwest of the border between Myanmar, Thailand and Laos. The earthquake killed between 75 and 151 people; including one fatality in Thailand. Hundreds of buildings were damaged in Myanmar and Thailand. An additional 212 people were injured.
The Burmese–Siamese War (1765–1767), also known as the fall of Ayoudhia (အယုဒ္ဓယပျက်ခန်း) was the second military conflict between the Konbaung dynasty of Burma (Myanmar) and the Ban Phlu Luang dynasty of the Ayutthaya Kingdom of Siam, and the war that ended the 417-year-old Ayutthaya Kingdom. Nonetheless, the Burmese were soon forced to give up their hard-won gains when the Chinese invasions of their homeland forced a complete withdrawal by the end of 1767. A new Siamese dynasty, to which the current Thai monarchy traces its origins, emerged to reunify Siam by 1771.
The 2012 Shwebo earthquake occurred at 07:42 local time on 11 November in Myanmar. It had a magnitude of 6.8 on the moment magnitude scale and a maximum perceived intensity of VIII (Severe) on the Mercalli intensity scale. The epicenter was near the town of Male, 52 km NNE of the city of Shwebo, 64 km west of Mogok and 120 km north of Mandalay. Significant damage and possible casualties have been reported from near the epicenter, with up to 26 people dead and many more injured. Part of a bridge under construction fell into the Irrawaddy River near Shwebo and a gold mine collapsed at Sintku. An aftershock with a magnitude of 5.8 followed at 17:24 local time.
Phu Nam Ron is a pass across the Tenasserim Hills on the border between Thailand and Myanmar, at an elevation of 350 metres (1,150 ft). The border checkpoint on the Thai side is in Ban Kao Subdistrict, Mueang Kanchanaburi District, Kanchanaburi Province.
The Burmese–Siamese War (1792–1794) or the Siamese Invasion of Tavoy was the conflict between the Kingdom of Burma under Konbaung dynasty and the Kingdom of Siam under the Chakri dynasty over the town of Tavoy and the Tenasserim Coast.
The 1912 Maymyo earthquake or Burma earthquake struck Burma on the morning of May 23, with an epicentre near Taunggyi and Pyin Oo Lwin in Shan State. The earthquake was initially calculated at 8.0 on the surface wave magnitude scale (Ms ) by Beno Gutenberg and Charles Francis Richter, and described by them as being one of the most remarkable seismic events in the early 1900s. Recent re-evaluation of the earthquake, however, have revised the magnitude to 7.6–7.9. It was preceded by two foreshocks on May 18 and 21 with respective intensities V and VII on the Rossi–Forel scale, while the mainshock was assigned IX. Shaking was felt throughout most of Burma, parts of Siam and Yunnan; an area covering approximately 375,000 square miles. It was one of the largest earthquakes in the country.
The 1930 Bago (Pegu) earthquake, also known as the Swa earthquake struck Myanmar on 5 May. The moment magnitude (Mw ) 7.4 earthquake had a focal depth of 35 km (22 mi) and maximum Rossi–Forel intensity of IX. The earthquake was the result of rupture along a 131 km (81 mi) segment of the Sagaing Fault—a major strike-slip fault that runs through the country. Extensive damage was reported in the southern part of the country, particularly in Bago and Yangon, where buildings collapsed and fires erupted. At least 550, and possibly up to 7,000 people were killed. A moderate tsunami was generated along the Burmese coast which caused minor damage to ships and a port. It was felt for over 570,000 km2 (220,000 sq mi) and as far as Shan State and Thailand. The mainshock was followed by many aftershocks; several were damaging; additional earthquakes occurred in July and December, killing dozens. The December earthquake was similarly-sized which also occurred along the Sagaing Fault.
The 1988 Lancang–Gengma earthquakes, also known as the 11.6 earthquakes by the Chinese media were a pair of devastating seismic events that struck Lancang and Gengma counties, Yunnan, near the border with Shan State, Burma. The earthquake measured moment magnitude (Mw ) 7.0 and was followed 13 minutes later by a 6.9 Mw shock. These earthquakes were assigned a maximum China seismic intensity of IX and X, respectively. Between 748 and 939 people were killed; more than 7,700 were injured. Both earthquakes resulted in US$270 million in damage and economic losses. Moderately large aftershocks continued to rock the region, causing additional casualties and damage.
The 1995 Menglian earthquake or 1995 Myanmar–China earthquake occurred on 12 July at 05:46:43 local time in the Myanmar–China border region. The earthquake had an epicenter on the Myanmar side of the border, located in the mountainous region of Shan State. It registered 7.3 on the Chinese surface wave magnitude scale (Ms ) and 6.8 on the moment magnitude scale (Mw ). With a maximum Mercalli intensity assigned at VIII, the quake killed eleven people and left another 136 injured. Over 100,000 homes in both countries were destroyed and 42,000 seriously damaged. Some damage to structures were also reported in Chiang Mai and Chiang Rai, Thailand. The low death toll from this earthquake was attributed to an early warning issued prior to it happening. Precursor events including foreshocks and some seismic anomalies led to an evacuation of the area before the mainshock struck. It is thought to be one of the few successfully predicted earthquakes in history.
The 1858 Prome earthquake occurred on August 24 at 15:38 local time in British Burma. The earthquake occurred with a magnitude of 7.6–8.3 on the moment magnitude scale. It had an epicenter in near the city of Pyay (Prome), Bago. The shock was felt with a maximum Modified Mercalli intensity of XI (Extreme) for about one minute. Severe damage was reported in Bago, and off the coast of Rakhine, an island sunk.
