2013 Balochistan Earthquakes
The 2013 Balochistan earthquakes took place in late September in southwestern Pakistan. The mainshock had a moment magnitude of 7.7 and a maximum Mercalli intensity of IX (''Violent''). At least 825 people were killed and hundreds more were injured. On 28 September, a M6.8 aftershock occurred to the north at a depth of , killing at least 22 people. Tectonic setting On a broad scale, the tectonics of southern and central Pakistan reflect a complex plate boundary where the India plate slides northward relative to the Eurasia plate in the east, and the Arabia plate subducts northward beneath the Eurasia plate in the Makran (western Pakistan). These motions typically result in north–south to northeast–southwest strike-slip motion at the latitude of the 24 September earthquake that is primarily accommodated on the Chaman Fault, with the earthquake potentially occurring on one of the southernmost strands of this fault system. Further, more in-depth studies will be required to i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pakistan Standard Time
Pakistan Standard Time ( ur, , abbreviated as PKT) is UTC+05:00 hours ahead of Coordinated Universal Time. The time zone is in use during standard time in Asia. History Pakistan had been following UTC+05:30 since 1907 (during the British Raj) and continued using it after independence in 1947. On 15 September 1951, following the findings of mathematician Mahmood Anwar, two time zones were introduced. ''Karachi Time (KART)'' was introduced in West Pakistan by adjusting 30 minutes off UTC+05:30 to UTC+05:00, while ''Dacca Time'' (DACT) was introduced in East Pakistan by subtracting 30 minutes off UTC+06:30 to UTC+06:00. The changes were made effective on 30, September 1951. PKT is measured in Gilgit, near the village of Naltar. In 1971, Karachi Time was renamed to Pakistan Standard Time. Daylight saving time Daylight saving time is no longer observed in Pakistan. [...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] |
Islamabad
Islamabad (; ur, , ) is the capital city of Pakistan. It is the country's ninth-most populous city, with a population of over 1.2 million people, and is federally administered by the Pakistani government as part of the Islamabad Capital Territory. Built as a planned city in the 1960s, it replaced Rawalpindi as Pakistan's national capital. The city is notable for its high standards of living, safety, cleanliness, and abundant greenery. Greek architect Constantinos Apostolou Doxiadis developed Islamabad's master plan, in which he divided it into eight zones; administrative, diplomatic enclave, residential areas, educational and industrial sectors, commercial areas, as well as rural and green areas administered by the Islamabad Metropolitan Corporation with support from the Capital Development Authority. Islamabad is known for the presence of several parks and forests, including the Margalla Hills National Park and the Shakarparian. It is home to several landmarks, includin ...

Rawalpindi
Rawalpindi ( or ; Urdu, ) is a city in the Punjab province of Pakistan. It is the fourth largest city in Pakistan after Karachi, Lahore and Faisalabad, and third largest in Punjab after Lahore and Faisalabad. Rawalpindi is next to Pakistan's capital Islamabad, and the two are jointly known as the "twin cities" because of the social and economic links between them. Rawalpindi is on the Pothohar Plateau, known for its ancient Hindu and Buddhist heritage, especially in the neighbouring town of Taxila, a UNESCO World Heritage Site. In 1765, the ruling Gakhars were defeated and the city came under Sikh rule, becoming an important city within the Sikh Empire based at Lahore. The city's ''Babu Mohallah'' neighbourhood was once home to a community of Jewish traders that had fled Mashhad, Persia, in the 1830s. The city was conquered by the British Raj in 1849, and in the late 19th century became the largest garrison town of the British Indian Army's Northern command as its climate ...

PAGER
A pager (also known as a beeper or bleeper) is a wireless telecommunications device that receives and displays alphanumeric or voice messages. One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to and originate messages using an internal transmitter. Pagers operate as part of a paging system which includes one or more fixed transmitters (or in the case of response pagers and two-way pagers, one or more base stations), as well as a number of pagers carried by mobile users. These systems can range from a restaurant system with a single low power transmitter, to a nationwide system with thousands of high-power base stations. Pagers were developed in the 1950s and 1960s, and became widely used by the 1980s. In the 21st century, the widespread availability of cellphones and smartphones has greatly diminished the pager industry. Nevertheless, pagers continue to be used by some emergency services and public safety personne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aftershock
In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to a consistent pattern. In some earthquakes the main rupture happens in two or more steps, resulting in multiple main shocks. These are known as doublet earthquakes, and in general can be distinguished from aftershocks in having similar magnitudes and nearly identical seismic waveforms. Distribution of aftershocks Most aftershocks are located over the full area of fault rupture and either occur along the fault plane itself or along other faults within the volume affected by the strain associated with the main shock. Typically, aftershocks are found up to a distance equal to the rupture length away from the fault plane. The pattern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Plate
The Indian Plate (or India Plate) is a minor tectonic plate straddling the equator in the Eastern Hemisphere. Originally a part of the ancient continent of Gondwana, the Indian Plate broke away from the other fragments of Gondwana , began moving north and carried Insular India with it. It was once fused with the adjacent Australian Plate to form a single Indo-Australian Plate, and recent studies suggest that India and Australia have been separate plates for at least 3 million years and likely longer. The Indian Plate includes most of modern South Asia (the Indian subcontinent) and a portion of the basin under the Indian Ocean, including parts of South China and western Indonesia, and extending up to but not including Ladakh, Kohistan and Balochistan. Plate movements Until roughly , the Indian Plate formed part of the supercontinent Gondwana together with modern Africa, Australia, Antarctica, and South America. Gondwana broke up as these continents drifted apart at different ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Plate
The Eurasian Plate is a tectonic plate that includes most of the continent of Eurasia (a landmass consisting of the traditional continents of Europe and Asia), with the notable exceptions of the Indian subcontinent, the Arabian subcontinent and the area east of the Chersky Range in eastern Siberia. It also includes oceanic crust extending westward to the Mid-Atlantic Ridge and northward to the Gakkel Ridge. The eastern edge is a boundary with the North American Plate to the north and a boundary with the Philippine Sea Plate to the south and possibly with the Okhotsk Plate and the Amurian Plate. The southern edge is a boundary with the African Plate to the west, the Arabian Plate in the middle and the Indo-Australian Plate to the east. The western edge is a divergent boundary with the North American Plate forming the northernmost part of the Mid-Atlantic Ridge, which is straddled by Iceland. All volcanic eruptions in Iceland, such as the 1973 eruption of Eldfell, the 1783 eruptio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabian Plate
The Arabian Plate is a minor tectonic plate in the Northern and Eastern Hemispheres. It is one of the three continental plates (along with the African and the Indian Plates) that have been moving northward in geological history and colliding with the Eurasian Plate. That is resulting in a mingling of plate pieces and mountain ranges extending in the west from the Pyrenees, crossing Southern Europe to Iran, forming the Alborz and the Zagros Mountains, to the Himalayas and ranges of Southeast Asia. Lexicology The ''Arabian Plate'' is a designation of the region, and it is also sometimes referred to as the ''Arab Plate''. Borders The Arabian Plate consists mostly of the Arabian Peninsula; it extends westward to the Sinai Peninsula and the Red Sea and northward to the Levant. The plate borders are: *East, with the Indian Plate, at the Owen Fracture Zone *South, with the African Plate to the west and the Somali Plate and the Indian Plate to the east *West, a left lateral fa ...
