1839 Ava Earthquake
The 1839 Ava earthquake, also known as the Amarapura earthquake or Inwa earthquake was a disastrous seismic event that struck central Burma on the morning of March 23. This earthquake with a moment magnitude as high as 8.3, was one of the biggest in the country since 1762. Shaking reached XI (''Extreme'') on the Modified Mercalli intensity scale, and was felt in Rangoon and Bhamo. Tectonic setting Burma is wedged between four tectonic plates; the Indian, Eurasian, Sunda and Burma plates that interact due to active geological processes. Along the west coast of the Coco Islands, off the Rahkine coast, and into Bangladesh, is a highly oblique convergent boundary known as the Sunda megathrust. This large fault marks the boundary between the Indian and Burma plates. The megathrust emerges from the seafloor in Bangladesh, where it runs parallel and east of the Chin Hills. This boundary continues to north of Burma where it ends at the eastern Himalayas. The Sagaing Fault is a mostly co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Konbaung Dynasty
The Konbaung dynasty ( my, ကုန်းဘောင်ခေတ်, ), also known as Third Burmese Empire (တတိယမြန်မာနိုင်ငံတော်) and formerly known as the Alompra dynasty (အလောင်းဘုရားမင်းဆက်, Alaungphra dynasty) and the Hunter dynasty (မုဆိုးမင်းဆက် Mokso dynasty / မုဆိုးဘိုမင်းဆက် Moksobo dynasty), was the last dynasty that ruled Myanmar, Burma/Myanmar from 1752 to 1885. It created the second-largest empire in history of Myanmar, Burmese history and continued the administrative reforms begun by the Toungoo dynasty, laying the foundations of the modern state of Burma. The reforms, however, proved insufficient to stem the advance of the British Empire, British, who defeated the Burmese in all three Anglo-Burmese Wars over a six-decade span (1824–1885) and ended the millennium-old Burmese monarchy in 1885. An expansionist dynasty, the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Himalayas
The Himalayas, or Himalaya (; ; ), is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the planet's highest peaks, including the very highest, Mount Everest. Over 100 peaks exceeding in elevation lie in the Himalayas. By contrast, the highest peak outside Asia (Aconcagua, in the Andes) is tall. The Himalayas abut or cross five countries: Bhutan, India, Nepal, China, and Pakistan. The sovereignty of the range in the Kashmir region is disputed among India, Pakistan, and China. The Himalayan range is bordered on the northwest by the Karakoram and Hindu Kush ranges, on the north by the Tibetan Plateau, and on the south by the Indo-Gangetic Plain. Some of the world's major rivers, the Indus, the Ganges, and the Tsangpo–Brahmaputra, rise in the vicinity of the Himalayas, and their combined drainage basin is home to some 600 million people; 53 million people live in the Himalayas. The Himalayas have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seismic Gap
A seismic gap is a segment of an active fault known to produce significant earthquakes that has not slipped in an unusually long time, compared with other segments along the same structure. There is a hypothesis or theory that states that over long periods of time, the displacement on any segment must be equal to that experienced by all the other parts of the fault. Any large and longstanding gap is, therefore, considered to be the fault segment most likely to suffer future earthquakes. The applicability of this approach has been criticised by some seismologists although earthquakes sometimes have occurred in previously-identified seismic gaps. Examples Loma Prieta Seismic Gap, California Prior to the 1989 Loma Prieta earthquake( = 6.9), that segment of the San Andreas fault system recorded much less seismic activity than other parts of the fault. The main shock and aftershocks of the 1989 event occurred within the previous seismic gap. Central Kuril gap, Russia Immediately foll ...

1956 Sagaing Earthquake
The 1956 Sagaing earthquake occurred on July 16, 1956, at 15:07 UTC. The earthquake was located near Sagaing, Burma. This earthquake had a magnitude of 7.1. Thirty-eight people died because of the earthquake. Several pagodas, including the Mingun Pagoda, were severely damaged. The earthquake was close to the Shan-Sagaing Fault. However, the focal mechanism remains undetermined. The intensity reached MM VIII to MM IX near the epicenter.

1946 Sagaing Earthquakes
The 1946 Sagaing earthquakes (also known as the Wuntho earthquakes) struck central Burma at 15:17 local time on 12 September. The first earthquake measured a magnitude of 7.3 and was followed by a 7.7 earthquake. Both events remain some of the largest in the country since the 1762 Arakan earthquake. Tectonic setting Both the mainshock and aftershock occurred along the Sagaing Fault; a continental transform fault boundary that links the Andaman Spreading Center to the south and the Main Himalayan Thrust to the north. It defines the boundary between the Burma Plate and Sunda Plate. The Sagaing Fault is the most active geological structure in the country and poses significant risks to major cities such as Yangon, Mandalay, and Naypyidaw. Another major tectonic feature in Myanmar is the Sunda Megathrust that runs off the coast of Western Myanmar and the Kabaw Fault that traces the foothills of the Arakan Mountains and Indo-Burman Range.

Earthquake Rupture
In seismology, an earthquake rupture is the extent of slip that occurs during an earthquake in the Earth's crust. Earthquakes occur for many reasons that include: landslides, movement of magma in a volcano, the formation of a new fault, or, most commonly of all, a slip on an existing fault. Nucleation A tectonic earthquake begins by an initial rupture at a point on the fault surface, a process known as nucleation. The scale of the nucleation zone is uncertain, with some evidence, such as the rupture dimensions of the smallest earthquakes, suggesting that it is smaller than 100 m while other evidence, such as a slow component revealed by low-frequency spectra of some earthquakes, suggest that it is larger. The possibility that the nucleation involves some sort of preparation process is supported by the observation that about 40% of earthquakes are preceded by foreshocks. However, some large earthquakes, such as the M8.6 1950 India - China earthquake., have no foreshocks and it re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sagaing
Sagaing (, ) is the former capital of the Sagaing Region of Myanmar. It is located in the Irrawaddy River, to the south-west of Mandalay on the opposite bank of the river. Sagaing with numerous Buddhist monasteries is an important religious and monastic centre. The pagodas and monasteries crowd the numerous hills along the ridge running parallel to the river. The central pagoda, Soon U Ponya Shin Pagoda, is connected by a set of covered staircases that run up the hill. Today, with about 70,000 inhabitants, the city is part of Mandalay built-up area with more than 1,022,000 inhabitants estimated in 2011. The city is a frequent tourist destination of day trippers. Within the city are the Sagaing Institute of Education, the Sagaing Education College, Sagaing University, Technological University (Sagaing), and co-operative university (Sagaing). Sagaing University was established on 11 February 2012. It is in Pakatoe Quarter, Sagaing Township, Sagaing Region, Myanmar. It has an ar ...

Meiktila
Meiktila (; ) is a city in central Burma on the banks of Meiktila Lake in the Mandalay Region at the junctions of the Bagan-Taunggyi, Yangon-Mandalay and Meiktila-Myingyan highways. Because of its strategic position, Meiktila is home to Myanmar Air Force's central command and Meiktila Air Force Base. The country's main aerospace engineering university, Myanmar Aerospace Engineering University is also located in Meiktila. As of 2021, the city had a population of 177,442. History The name Meiktila comes from Mithila, the name of an ancient Indian kingdom. The history of Meiktila is closely tied to that of central Myanmar's dry zone, home of the Bamar people. The region had been part of various Bamar kingdoms at least from 11th century CE to 19th century CE before the British Empire took over all of Upper Myanmar in 1885. Meiktila was part of the 1945 Battle of Meiktila and Mandalay, during which the Allied forces under William Slim defeated the Japanese forces. Soon after Burma ...

Mandalay
Mandalay ( or ; ) is the second-largest city in Myanmar, after Yangon. Located on the east bank of the Irrawaddy River, 631km (392 miles) (Road Distance) north of Yangon, the city has a population of 1,225,553 (2014 census). Mandalay was founded in 1857 by King Mindon, replacing Amarapura as the new royal capital of the Konbaung dynasty. It was Burma's final royal capital before the kingdom's annexation by the British Empire in 1885. Under British rule, Mandalay remained commercially and culturally important despite the rise of Yangon, the new capital of British Burma. The city suffered extensive destruction during the Japanese conquest of Burma in the Second World War. In 1948, Mandalay became part of the newly independent Union of Burma. Today, Mandalay is the economic centre of Upper Myanmar and considered the centre of Burmese culture. A continuing influx of illegal Chinese immigrants, mostly from Yunnan, since the late 20th century, has reshaped the city's ethnic mak ...

Nay Pyi Daw
Naypyidaw, officially spelled Nay Pyi Taw (; ), is the capital and third-largest city of Myanmar. The city is located at the centre of the Naypyidaw Union Territory. It is unusual among Myanmar's cities, as it is an entirely planned city outside of any state or region. The city, then known only as Pyinmana District, officially replaced Yangon as the administrative capital of Myanmar on 6 November 2005; its official name was revealed to the public on Armed Forces Day, 27 March 2006. As the seat of the government of Myanmar, Naypyidaw is the site of the Union Parliament, the Supreme Court, the Presidential Palace, the official residences of the Cabinet of Myanmar and the headquarters of government ministries and military. Naypyidaw is notable for its unusual combination of large size and very low population density. The city hosted the 24th and 25th ASEAN Summit, the 3rd BIMSTEC Summit, the Ninth East Asia Summit, the 2013 Southeast Asian Games and the 2014 AFC U-19 Championsh ...

Main Frontal Thrust
The Main Frontal Thrust (MFT), also known as the Himalayan Frontal Thrust (HFT) is a geological fault in the Himalayas that defines the boundary between the Himalayan foothills and Indo-Gangetic Plain. The fault is well expressed on the surface thus could be seen via satellite imagery. It is the youngest and southernmost thrust structure in the Himalaya deformation front. It is a splay branch of the Main Himalayan Thrust (MHT) as the root décollement. It runs parallel to other major splays of the MHT; Main Boundary Thrust (MBT) and Main Central Thrust (MCT). The Sunda Megathrust, which extends from the Banda Islands to Myanmar is joined with the MFT. The fault strikes in a NW-SE direction and dips at an angle of 20° to 30° in the north. Main Boundary Thrust The Main Boundary Thrust (MBT) is another major thrust fault in the Himalaya orogenic wedge that was active in the Cenozoic The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million ...

Divergent Boundary
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Current research indicates that complex convection within the Earth's mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary. This supplies the area with huge amounts of heat and a reduction in pressure that melts rock from the asthenosphere (or upper mantle) beneath the rift area, forming large flood basalt or lava flows. Each eruption occurs in only a part of the plate boundary at any one time, but when it does occur, it fills in the opening gap as the two opposing plates move away from each other. ...
