September 2022 Afghanistan Earthquake
On September 5, 2022, a reverse faulting earthquake with a moderate magnitude of 5.1 struck Kunar Province, Afghanistan, close to the city of Jalalabad. Tectonic setting Much of Afghanistan is situated in a broad zone of continental deformation within the Eurasian Plate. Seismic activity in Afghanistan is influenced by the subduction of the Arabian Plate to the west and the oblique subduction of the Indian Plate in the east. The subduction rate of the Indian Plate along the continental convergent boundary is estimated to be 39 mm/yr or higher. Transpression due to the plates interacting is associated with high seismicity within the shallow crust. Seismicity is detectable to a depth of beneath Afghanistan due to plate subduction. These earthquakes beneath the Hindu Kush are the result of movement on faults accommodating detachment of the subducted crust. Within the shallow crust, the Chaman Fault represents a major transform fault associated with large shallow eart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverse Fault
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...

Hindu Kush
The Hindu Kush is an mountain range in Central and South Asia to the west of the Himalayas. It stretches from central and western Afghanistan, Quote: "The Hindu Kush mountains run along the Afghan border with the North-West Frontier Province of Pakistan". into northwestern Pakistan and far southeastern Tajikistan. The range forms the western section of the ''Hindu Kush Himalayan Region'' (''HKH''); to the north, near its northeastern end, the Hindu Kush buttresses the Pamir Mountains near the point where the borders of China, Pakistan and Afghanistan meet, after which it runs southwest through Pakistan and into Afghanistan near their border. The eastern end of the Hindu Kush in the north merges with the Karakoram Range.Karakoram Range: MOUNTAINS, ASIA Encyclopædia Britannica Towards its s ...

Hans (magazine)
''Hans'' is the oldest and one of the most prestigious literary magazine, in Hindi language. History Established by Premchand in 1930, it had Mahatma Gandhi in its editorial board and continued till 1956, when it was shut down by Amrit Rai, due to financial woes. The magazine was revived in 1986 by Rajendra Yadav Rajendra Yadav (28 August 1929 – 28 October 2013) was a Hindi fiction writer, and a pioneer of the 'Nayi Kahani' movement of Hindi literature. He edited the literary magazine ''HANS'', which was founded by Munshi Premchand in 1930 but ceased ..., a noted short-story writer and novelist. His daughter Rachana, was bequeathed the ownership, after his death in 2013. Audience The magazine is currently priced at INR 50 per issue and claims a consistent readership of about twelve thousand readers every month — two and a half thousand annual subscribers plus around nine thousand copies sold through vendors.

Dormitory
A dormitory (originated from the Latin word ''dormitorium'', often abbreviated to dorm) is a building primarily providing sleeping and residential quarters for large numbers of people such as boarding school, high school, college or university students. In some countries, it can also refer to a room containing several beds accommodating people. Terminology Dorm and residence hall The terms "dorm" is often used in the US. However, within the residence life community, the official term "residence hall" is preferred. According to the University of Oregon, their facilities "provide not just a place to sleep, but also opportunities for personal and educational growth. Highly trained Residence Life staff and Hall Government officers support this objective by creating engaging activities and programs in each hall or complex." In the UK, the preferred term in the context of student housing is "halls," short for "halls of residence." In English-speaking Canada, the common term is "r ...

Radio Azadi
Radio Azadi (formerly Radio Free Afghanistan) is the Afghan branch of the U.S. government's Radio Free Europe / Radio Liberty's (RFE/RL) external broadcast services. It broadcasts 12 hours daily as part of a 24-hour stream of programming in conjunction with Voice of America (VOA). Radio Free Afghanistan first aired in Afghanistan from 1985 to 1993 and was re-launched in January 2002. Radio Azadi produces a variety of cultural, political, and informational programs that are transmitted to listeners via shortwave radio, satellite and AM and FM signals provided by the International Broadcasting Bureau. According to Radio Azadi, their mission is "to promote and sustain democratic values and institutions in Afghanistan by disseminating news, factual information and ideas". Present The U.S. Congress appropriated funding for broadcasting to Afghanistan in December 2001 as part of an effort to build a peaceful and democratic country, following the U.S.-led ouster of the Taliban reg ...

Geology Of The Himalayas
The geology of the Himalayas is a record of the most dramatic and visible creations of the immense mountain range formed by plate tectonic forces and sculpted by weathering and erosion. The Himalayas, which stretch over 2400 km between the Namcha Barwa syntaxis at the eastern end of the mountain range and the Nanga Parbat syntaxis at the western end, are the result of an ongoing orogeny — the collision of the continental crust of two tectonic plates, namely, the Indian Plate thrusting into the Eurasian Plate. The Himalaya-Tibet region supplies fresh water for more than one-fifth of the world population, and accounts for a quarter of the global sedimentary budget. Topographically, the belt has many superlatives: the highest rate of uplift (nearly 10 mm/year at Nanga Parbat), the highest relief (8848 m at Mt. Everest Chomolangma), among the highest erosion rates at 2–12 mm/yr, the source of some of the greatest rivers and the highest concentration of ...

Thrust Fault
A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks. Thrust geometry and nomenclature Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an ''overthrust'' or ''overthrust fault''. Erosion can remove part of the overlying block, creating a ''fenster'' (or ''window'') – when the underlying block is exposed only in a relatively small area. When erosion removes most of the overlying block, leaving island-like remnants resting on the lower block, the remnants are called ''klippen'' (singular ''klippe''). Blind thrust faults If the fault plane terminates before it reaches the Earth's surface, it is referred to as a ''blind thrust'' fault. Because of the lack of surface evidence, blind thr ...

Transpression
In geology, transpression is a type of strike-slip deformation that deviates from simple shear because of a simultaneous component of shortening perpendicular to the fault plane. This movement ends up resulting in oblique shear. It is generally very unlikely that a deforming body will experience "pure" shortening or "pure" strike-slip. The relative amounts of shortening and strike-slip can be expressed in the convergence angle alpha which ranges from zero (ideal strike-slip) to 90 degrees (ideal convergence). During shortening, unless material is lost, transpression produces vertical thickening in the crust. Transpression that occurs on a regional scale along plate boundaries is characterized by oblique convergence. More locally, transpression occurs within restraining bends in strike-slip fault zones. Transpressional structures Transpressional shear zones are characterized by an association of structures that suggest zone-normal shortening and zone-parallel shearing. Commonly ...
