March 2011 Myanmar Earthquake
The 2011 Tarlay earthquake occurred on 24 March in Shan State, Myanmar. The earthquake measured 6.8 and had an epicenter northwest of the border between Myanmar, Thailand and Laos. It occurred in a region accommodating tectonic deformation brought by the collision between the Indo-Australian and Eurasian plates. Strike-slip faulting along the Nan Ma Fault was identified as the cause. There were between 75 and 151 fatalities; including one death in Thailand. An additional 212 people were injured. Hundreds of buildings and some transport infrastructure were damaged in Myanmar and Thailand. Tectonic setting Myanmar lies at the junction of the Alpide belt and Sunda Arc. In northern Myanmar, continental collision is ongoing between the between the northward moving Indo-Australian Plate and the Eurasian Plate. Collision also occurs along the Indo-Burman Ranges (Patkai, Naga and Chin Hills) and Arakan Mountains of western Myanmar. In this zone of highly oblique collision, most of th ...

Myanmar
Myanmar, ; UK pronunciations: US pronunciations incl. . Note: Wikipedia's IPA conventions require indicating /r/ even in British English although only some British English speakers pronounce r at the end of syllables. As John Wells explains, the English spellings of both Myanmar and Burma assume a non-rhotic variety of English, in which the letter r before a consonant or finally serves merely to indicate a long vowel: �mjænmɑː, ˈbɜːmə So the pronunciation of the last syllable of Myanmar as ɑːror of Burma as ɜːrməby some speakers in the UK and most speakers in North America is in fact a spelling pronunciation based on a misunderstanding of non-rhotic spelling conventions. The final ''r'' in ''Myanmar'' was not intended for pronunciation and is there to ensure that the final a is pronounced with the broad ''ah'' () in "father". If the Burmese name my, မြန်မာ, label=none were spelled "Myanma" in English, this would be pronounced at the end by al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shan Plateau
The Shan Hills ( my, ရှမ်းရိုးမ; ''Shan Yoma''), also known as Shan Highland, is a vast mountainous zone that extends through Yunnan to Myanmar and Thailand. The whole region is made up of numerous mountain ranges separated mostly by narrow valleys as well as a few broader intermontane basins. The ranges in the area are aligned in such a way that they link to the foothills of the Himalayas further to the northwest. The highest point is Loi Leng, at 2,673 m elevation. Other peaks are 2,565 m Mong Ling Shan, 2,565 m Doi Inthanon and 2,563 m Loi Pangnao. All are ultra prominent peaks of Southeast Asia. Etymology The name of the massif or system of ranges, is derived from the Shan State and its peoples, said in its turn to be derived from the word " Siam", that occupies most of the Shan Highland area. Since it was relatively unexplored until recent times, the Shan mountainous region was referred to as the "Shan Plateau" in geographic works of the B ...

Mekong River
The Mekong or Mekong River is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth longest river and the third longest in Asia. Its estimated length is , and it drains an area of , discharging of water annually. From the Tibetan Plateau the river runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia. Names The Mekong was originally called ''Mae Nam Khong'' from a contracted form of Tai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother of Water ) is used for large rivers and ''Khong'' is the proper name referred to as "River Khong". However, ''Khong'' is an archaic word meaning "river", loaned from Austroasiatic languages, such as Vietnamese ''sông'' (from *''krong'') and Mon ''kruŋ'' "river", which led to ...

Geomorphic
Geomorphology (from Ancient Greek: , ', "earth"; , ', "form"; and , ', "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field. Overview Earth's surface is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography. Surface processes com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1995 Myanmar–China Earthquake
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 () and 6.8 on the moment magnitude scale (). 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. Tectonic setting The Shan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1988 Lancang–Gengma Earthquakes
The 1988 Lancang–Gengma earthquakes ( simplified Chinese: 澜沧江－耿马地震; traditional Chinese: 瀾滄江－耿馬地震; pinyin: ''Láncāngjiāng-gěng mǎ dìzhèn''), also known as the 11.6 earthquakes by the Chinese media were a pair of devastating seismic events which struck Lancang and Gengma counties, Yunnan, near the border with Shan State, Burma in the Shan Plateau. The pair of earthquakes occurred thirteen minutes apart with the first registering 7.7 on the moment magnitude scale and second measuring 7.2 on the surface wave magnitude scale. The two earthquakes were assigned their maximum Mercalli intensities of X (''Extreme'') and IX (''Violent'') respectively. At least 939 people were killed and more than 7,700 were injured in 20 counties across five prefectures in Yunnan, making it the worst in the country since the 1976 Tangshan earthquake. Both earthquakes resulted in US $270 million (in 1988 dollars) in damages and economical losses. Moderately la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focal Mechanism
The focal mechanism of an earthquake describes the deformation in the source region that generates the seismic waves. In the case of a fault-related event it refers to the orientation of the fault plane that slipped and the slip vector and is also known as a fault-plane solution. Focal mechanisms are derived from a solution of the moment tensor for the earthquake, which itself is estimated by an analysis of observed seismic waveforms. The focal mechanism can be derived from observing the pattern of "first motions", that is, whether the first arriving P waves break up or down. This method was used before waveforms were recorded and analysed digitally and this method is still used for earthquakes too small for easy moment tensor solution. Focal mechanisms are now mainly derived using semi-automatic analysis of the recorded waveforms. Moment tensor solutions The moment tensor solution is typically displayed graphically using a so-called ''beachball'' diagram. The pattern o ...

International Seismological Centre
The International Seismological Centre (ISC) is a non-governmental, nonprofit organisation charged with the final collection, definitive analysis and publication of global seismicity. The ISC was formed in 1964 as an international organisation independent of national governments that would carry on the work of the International Seismological Summary in collecting and analyzing seismic data from around the world, and particularly to handle increased flow of data from the World-Wide Standard Seismograph Network (WWSSN), also established that year. The ISC considers its prime task to be the collection and re-analysis of all available earthquake seismic date in order to produce definitive data on earthquakes. The ISC's catalog is considered "the most complete and authoritative final depository of global earthquake parameter data." Purpose The main scientific goal of the Centre is the definitive compilation of earthquake information and the readings on which they are based. Collect ...

Golden Triangle (Southeast Asia)
The Golden Triangle is the area where the borders of Thailand, Laos, and Myanmar meet at the confluence of the Ruak and Mekong rivers. The name "Golden Triangle"—coined by the CIA—is commonly used more broadly to refer to an area of approximately that overlaps the mountains of the three adjacent countries. Along with Afghanistan in the Golden Crescent, it has been one of the largest opium-producing areas of the world since the 1950s. Most of the world's heroin came from the Golden Triangle until the early 21st century when Afghanistan became the world's largest producer."Afghanistan Again Tops List of Illegal Drug Producers" .

Focal Depth
In seismology, the depth of focus or focal depth refers to the depth at which an earthquake occurs. Earthquakes occurring at a depth of less than are classified as shallow-focus earthquakes, while those with a focal depth between and are commonly termed mid-focus or intermediate-depth earthquakes. In subduction zones, where older and colder oceanic crust sinks under another tectonic plate, deep-focus earthquakes may occur at much greater depths in the mantle, ranging from up to . The cause of deep-focus earthquakes is still not entirely understood since subducted lithosphere at that pressure and temperature regime should not exhibit brittle behavior. A possible mechanism for the generation of deep-focus earthquakes is faulting caused by olivine undergoing a phase transition into a spinel structure, with which they are believed to be associated. Earthquakes at this depth of focus typically occur at oceanic-continental convergent boundaries, along Wadati–Benioff zones. Discove ...
