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.

Sagaing Fault
The Sagaing Fault is a major fault in Burma, a mainly continental right-lateral transform fault between the Indian Plate and Sunda Plate. It links the divergent boundary in the Andaman Sea with the zone of active continental collision along the Himalayan front. It passes through populated cities of Mandalay, Yamethin, Pyinmana, the capital Naypyidaw, Toungoo and Pegu before dropping off into the Gulf of Martaban, running for a total length of over 1200 kilometers. Geomorphology The Sagaing Fault begins offshore in the Andaman Sea before passing through the central Myanmar basin. The fault has a relatively low topographical relief for most of its length compared to the Shan Scarp Fault to the west. Slip rate and displacement The total slip rate across the Indian–Sunda Plate boundary is about 35 mm/yr, of which 18 mm/yr is accommodated by the Sagaing Fault, according to GPS data. The measured maximum displacement along the fault is about 100 km, although several auth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Earthquakes In Myanmar
Myanmar (also known as Burma) is the northwesternmost country of mainland Southeast Asia located on the Indochinese peninsula. With an area of 261,228 sq mi (676,578 sq km), it is the second largest country in Southeast Asia and the largest on mainland Southeast Asia. The kite-shaped country stretches from 10'N to 20'N for 1,275 miles (2,050 km) with a long tail running along the western coast of the Malay Peninsula. Myanmar lies along the Indian and Eurasian Plates, to the southeast of the Tibetan Plateau. To its west is the Bay of Bengal and to its south is the Andaman Sea. The country is nestled between several mountain ranges with the Arakan Mountains on the west and the Shan Plateau dominating the east. The central valley follows the Irrawaddy River, the most economically important river to the country with 39.5 million people, including the largest city Yangon, living within its basin. The country is home to many diverse ethnic groups, with 135 officially recognize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Earthquakes In Myanmar
Myanmar is one of the most seismically active regions in the world. Oblique subduction, block rotation, and a transform margin has been responsible for the seismic activities of the country. The Sagaing Fault is one of the largest sources of earthquakes in the country, having produced deadly quakes in the past centuries. Along the western coast, offshore Rahkine State, the Sunda Megathrust, where the Indian Plate dives beneath the Burma Plate is capable of producing large events and tsunamis like the 2004 earthquake. Intermediate depth earthquakes east of the Chin Range also pose a risk to people. The Shan Plateau is another source of earthquakes, hosting many active strike-slip faults that accommodate block rotation of the Sunda Plate. Notable earthquakes in the history of Myanmar include the following: Earthquakes Tsunamis affecting Myanmar * 1881 Nicobar Islands earthquake * 1941 Andaman Islands earthquake * 2004 Indian Ocean earthquake See also *Geology of Myanmar ...

List Of Earthquakes In 1946
This is a list of earthquakes in 1946. Only magnitude 6.0 or greater earthquakes appear on the list. Lower magnitude events are included if they have caused death, injury or damage. Events which occurred in remote areas will be excluded from the list as they wouldn't have generated significant media interest. All dates are listed according to UTC time. Several great shocks affected the planet in 1946. The largest was one of the most significant in human terms. The quake itself was a magnitude 8.6 striking on April 1 in Alaska resulting in a tsunami mainly affecting Hawaii. The consequence of this apart from many deaths was the foundation of the Pacific Tsunami Warning Center. This organisation has helped to substantially reduce the death toll of tsunamis in the Pacific, although there have been a few exceptions, including the 2011 Japan event. Japan itself was heavily affected in 1946 by a large quake hitting in December, causing 1,362 deaths. The Dominican Republic was another n ...

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 ...

Coulomb Stress Transfer
Coulomb stress transfer is a seismic-related geological process of stress changes to surrounding material caused by local discrete deformation events. Using mapped displacements of the Earth's surface during earthquakes, the computed Coulomb stress changes suggest that the stress relieved during an earthquake not only dissipates but can also move up and down fault segments, concentrating and promoting subsequent tremors. Importantly, Coulomb stress changes have been applied to earthquake-forecasting models that have been used to assess potential hazards related to earthquake activity. Coulomb stress change The Coulomb failure criterion requires that the Coulomb stress exceeds a value σf defined by the shear stress τB, normal stress σB, pore pressure p, and coefficient of friction μ of a failure plane, such that It is also often assumed that changes in pore fluid pressure induced by changes in stress are proportional to the normal stress change across the fault plane. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Fault Outside Mandalay
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 area ...
