2013 Saravan Earthquake
The 2013 Saravan earthquake occurred with a moment magnitude of 7.7 at 15:14 pm Daylight saving time in Iran, IRDT (UTC+4:30) on 16 April. The shock struck a mountainous area between the cities of Saravan, Iran, Saravan and Khash, Iran, Khash in Sistan and Baluchestan Province, Iran, close to the border with Pakistan, with a duration of about 25 seconds. The earthquake occurred at an intermediate depth in the Arabian plate lithosphere, near the boundary between the subducting Arabian Plate and the overriding Eurasian Plate at a depth of about 80 km. It was the largest earthquake in Iran within the last 300 years, equal in magnitude to the one that 1721 Tabriz earthquake, shook East Azerbaijan in 1721, killing up to 250,000 people, and possibly the largest in the last half-century. The earthquake followed a 2013 Bushehr earthquake, magnitude 6.3 event near Bushehr. The town of Mashkel was close to the quake's epicentre, and around 85 percent of the city's buildings were demo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daylight Saving Time In Iran
Daylight saving time in Iran was the practice of setting the clock forward by one hour between the first day of Farvardin (21–22 March) in the Iranian calendar and the last day of Shahrivar (21–22 September), which has been observed during years 1978–1980, 1989–2005, and 2008–2022. Abolishment In 2006, Iran abolished daylight saving time (DST); however, in September 2007, the Iranian parliament passed a law restoring DST starting from March 21, 2008, in spite of opposition by the contemporary government. A number of deputies of The Eleventh Term of the Islamic Consultative Assembly of Iran drafted a plan to abolish daylight saving time in the country. This plan was approved by the Islamic Consultative Assembly of Iran on March 15, 2022. However, it was rejected by the Guardian Council due to it not clearly determining when this rule must be applied, and not clarifying if the Iranian government had authority to change it or not. After solving these ambiguities, it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delhi
Delhi, officially the National Capital Territory (NCT) of Delhi, is a city and a union territory of India containing New Delhi, the capital of India. Straddling the Yamuna river, primarily its western or right bank, Delhi shares borders with the state of Uttar Pradesh in the east and with the state of Haryana in the remaining directions. The NCT covers an area of . According to the 2011 census, Delhi's city proper population was over 11 million, while the NCT's population was about 16.8 million. Delhi's urban agglomeration, which includes the satellite cities of Ghaziabad, Faridabad, Gurgaon and Noida in an area known as the National Capital Region (NCR), has an estimated population of over 28 million, making it the largest metropolitan area in India and the second-largest in the world (after Tokyo). The topography of the medieval fort Purana Qila on the banks of the river Yamuna matches the literary description of the citadel Indraprastha in the Sanskrit ...

List Of Earthquakes In Pakistan
Pakistan is one of the most seismically active countries in the world, being crossed by several major faults. As a result, earthquakes in Pakistan occur often and are destructive. Geology Pakistan geologically overlaps both the Eurasian and Indian tectonic plates. Balochistan, the Federally Administered Tribal Areas, Khyber Pakhtunkhwa and Gilgit-Baltistan provinces lie on the southern edge of the Eurasian Plate on the Iranian Plateau. Sindh, Punjab and Azad Jammu & Kashmir provinces lie on the north-western edge of the Indian plate in South Asia. Hence this region is prone to violent earthquakes, as the two tectonic plates collide.

List Of Earthquakes In Iran
Iran is one of the most seismically active countries in the world, being crossed by several major faults that cover at least 90% of the country. As a result, earthquakes in Iran occur often and are destructive. Geology and history The Iranian plateau is subject to most types of tectonic activity, including active folding, faulting and volcanic eruptions. It is well known for its long history of disastrous earthquake activity. Not only have these earthquakes killed thousands, but they have also led to waste of valuable natural resources. Since 1900, at least 126,000 fatalities have resulted from earthquakes in Iran. In addition, the Iranian Plate is bordered by the Indian Plate (to the southeast), the Eurasian Plate (to the north), and the Arabian Plate (to the south and west), which is where the Zagros fold and thrust belt (an ancient subduction zone) lies.

Eurasia 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] |
Subduction
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Makran Trench
The Makran Trench is the physiographic expression of a subduction zone along the northeastern margin of the Gulf of Oman adjacent to the southwestern coast of Balochistan of Pakistan and the southeastern coast of Iran. In this region the oceanic crust of the Arabian Plate is being subducted beneath the continental crust of the Eurasian Plate. Tectonics In the Makran region, the Arabian Plate subducts beneath the Eurasian Plate at ~2-4cm/yr. This subduction is associated with an accretionary wedge of sediments which has developed since the Cenozoic. To the west, the Makran Trench is connected by the Minab Fault system to the Zagros fold and thrust belt. To the east, the Makran Trench is bounded by the transpressional strike-slip Ornach-Nal and Chaman Faults, which connect to the Himalayan orogeny. The Makran Subduction Zone is often split into two segments: the east and west. The Sonne fault divides the two. Though largely much quieter than many other subduction zones, s ...

Continental Collision
In geology, continental collision is a phenomenon of plate tectonics that occurs at convergent boundaries. Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together. Continental collision is only known to occur on Earth. Continental collision is not an instantaneous event, but may take several tens of millions of years before the faulting and folding caused by collisions stops. The collision between India and Asia has been going on for about 50 million years already and shows no signs of abating. Collision between East and West Gondwana to form the East African Orogen took about 100 million years from beginning (610 Ma) to end (510 Ma). The collision between Gondwana and Laurasia to form Pangea occurred in a relatively brief interval, about 50 million years long.

Strait Of Hormuz
The Strait of Hormuz ( fa, تنگه هرمز ''Tangeh-ye Hormoz'' ar, مَضيق هُرمُز ''Maḍīq Hurmuz'') is a strait between the Persian Gulf and the Gulf of Oman. It provides the only sea passage from the Persian Gulf to the open ocean and is one of the world's most strategically important choke points. On the north coast lies Iran, and on the south coast lies the Musandam peninsula, shared by the United Arab Emirates and Musandam Governorate, an exclave of Oman. The strait is about long, with a width varying from about to . A third of the world's liquefied natural gas and almost 25% of total global oil consumption passes through the strait, making it a highly important strategic location for international trade. Etymology The opening to the Persian Gulf was described, but not given a name, in the ''Periplus of the Erythraean Sea'', a 1st-century mariner's guide: In the 10th17th centuries AD, the Kingdom of Ormus, which seems to have given the strait ...

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 ...

Arabian Tectonic Plate Overview Map
The Arabian Peninsula, (; ar, شِبْهُ الْجَزِيرَةِ الْعَرَبِيَّة, , "Arabian Peninsula" or , , "Island of the Arabs") or Arabia, is a peninsula of Western Asia, situated northeast of Africa on the Arabian Plate. At , the Arabian Peninsula is the largest peninsula in the world. Geographically, the Arabian Peninsula includes Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE), and Yemen, as well as the southern portions of Iraq and Jordan. The largest of these is Saudi Arabia. In the classical era, the southern portions of modern-day Syria, Jordan, and the Sinai Peninsula were also considered parts of Arabia (see Arabia Petraea). The Arabian Peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and southwest, the Persian Gulf and the Gulf of Oman to the northeast, the Levant and Mesopotamia to the north and the Arabian Sea and the Indian Oce ...
