1853 Shiraz Earthquake
The Fars region of Iran was struck by a major earthquake on either 22 April or 5 May 1853. The city of Shiraz and the surrounding area were severely affected, with almost all buildings destroyed. At least 9,000 people were killed, with some estimates reaching 13,000. Tectonic setting Iran lies across the complex plate boundary where the Arabian Plate is colliding with the Eurasian Plate. The Fars region lies within the outermost part of the Zagros fold and thrust belt. This Fars Domain is affected by the presence of thick Neoproterozoic salt of the Hormuz Formation, forming part of the so-called ''simply folded zone''. Despite its name, the folding is accompanied by thrusting, with some strike-slip faulting, such as on the right-lateral Kazerun fault system. From the analysis of hypocentral depths and focal mechanisms, the earthquakes are caused by both faulting within the underlying basement and towards the base of the thick sedimentary cover sequence. Almost all earthquakes o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iran
Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Turkey to the west, by Azerbaijan and Armenia to the northwest, by the Caspian Sea and Turkmenistan to the north, by Afghanistan and Pakistan to the east, and by the Gulf of Oman and the Persian Gulf to the south. It covers an area of , making it the 17th-largest country. Iran has a population of 86 million, making it the 17th-most populous country in the world, and the second-largest in the Middle East. Its largest cities, in descending order, are the capital Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz. The country is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Medes, an ancient Iranian people, in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Great fo ...

Blind 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 ...

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.

Vakil Bazaar
Vakil Bazaar ( fa, بازار وکیل) is the main bazaar of Shiraz, Iran, located in the historical center of the city. It is thought that the market originally was established by the Buwayhids in the 11th century AD, and was completed mainly by the Atabaks of Fars, and was renamed after Karim Khan Zand only in the 18th century. The bazaar has beautiful courtyards, caravansarais, bath houses, and old shops which are deemed among the best places in Shiraz to buy Persian rugs, spices, copper handicrafts and antiques. Like other Middle Eastern bazaars, there are a few mosques and Imamzadehs constructed beside or behind the bazaar. See also * Iranian architecture Iranian architecture or Persian architecture ( Persian: معمارى ایرانی, ''Memāri e Irāni'') is the architecture of Iran and parts of the rest of West Asia, the Caucasus and Central Asia.

Vakil Mosque
The Vakil Mosque ( fa, مسجد وکیل - ''Masjed-e Vakil'') is a mosque in Shiraz, southern Iran, situated to the west of the Vakil Bazaar next to its entrance. This mosque was built between 1751 and 1773, during the Zand period; however, it was restored in the 19th century during the Qajar period. ''Vakil'' means ''regent'', which was the title used by Karim Khan, the founder of Zand Dynasty. Shiraz was the seat of Karim Khan's government and he endowed many buildings, including this mosque. Specifications Vakil Mosque covers an area of 8,660 square meters. It has only two iwans instead of the usual four, on the northern and southern sides of a large open court. The iwans and court are decorated with typical Shirazi ''haft rangi'' tiles, a characteristic feature of the art and industry of Shiraz during the latter half of the 18th century. Its night prayer hall (Shabestan), with an area of approximately 2,700 square meters, contains 48 monolithic pillars carved in spirals, eac ...

Shah Cheragh
Shāh Chérāgh ( fa, شاه چراغ) or Shahcheragh Shrine is the tomb of Ahmed bin Musa ( Imam Reza's brother) in the center of Shiraz. It is the third most important shrine in Shia Islam in Iran, after the Imam Reza shrine and Fatima Masumeh Shrine. Ahmed bin Musa traveled to Khorasan on the way to join his brother, but he was killed by Al-Ma'mun Abbasid Caliphate in Shiraz. ''Shāh-é-Chérāgh'' is a Persian term for "King of the Light". The site is the most important place of pilgrimage within the city of Shiraz. Overview The tombs became celebrated pilgrimage centres in the 14th century when Queen Tashi Khatun erected a mosque and theological school in the vicinity. The site was given this name due to the nature of the discovery of the site by Ayatullah Dastghā'ib (the great grandfather of the contemporary Ayatullah Dastghā'ib). He used to see light from a distance and decided to investigate the source. He found that the light was being emitted by a grave within a ...

Qanat
A qanat or kārīz is a system for transporting water from an aquifer or water well to the surface, through an underground aqueduct; the system originated approximately 3,000 BC in what is now Iran. The function is essentially the same across North Africa and the Middle East but the system operates under a variety of regional names: ''qanat'' or kārīz in Iran, ''foggara'' in Algeria, ''khettara'' in Morocco, ''falaj'' in Oman, ''karez'' in Afghanistan, ''auyoun'' in Saudi Arabia, et al. The largest extant and functional qanat systems are located in Iran, Afghanistan, Oman, the oases of Turfan region of China, Algeria, and Pakistan. This is a system of water supply that allows water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. The system has the advantage of being resistant to natural disasters such as earthquakes and floods, and to deliberate destruction in war. Furthermore, it is almost insensitive to the level ...

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] |
Foreshock
A foreshock is an earthquake that occurs before a larger seismic event (the mainshock) and is related to it in both time and space. The designation of an earthquake as ''foreshock'', ''mainshock'' or aftershock is only possible after the full sequence of events has happened. Occurrence Foreshock activity has been detected for about 40% of all moderate to large earthquakes, and about 70% for events of M>7.0. They occur from a matter of minutes to days or even longer before the main shock; for example, the 2002 Sumatra earthquake is regarded as a foreshock of the 2004 Indian Ocean earthquake with a delay of more than two years between the two events. Some great earthquakes (M>8.0) show no foreshock activity at all, such as the M8.6 1950 India–China earthquake. The increase in foreshock activity is difficult to quantify for individual earthquakes but becomes apparent when combining the results of many different events. From such combined observations, the increase before the mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Rupture
In seismology, surface rupture (or ground rupture, or ground displacement) is the visible offset of the ground surface when an earthquake rupture along a fault affects the Earth's surface. Surface rupture is opposed by buried rupture, where there is no displacement at ground level. This is a major risk to any structure that is built across a fault zone that may be active, in addition to any risk from ground shaking. Surface rupture entails vertical or horizontal movement, on either side of a ruptured fault. Surface rupture can affect large areas of land. __TOC__ Lack of surface rupture Not every earthquake results in surface rupture, particularly for smaller and deeper earthquakes. In some cases, however, the lack of surface effects is because the fault that moved does not reach the surface. For example, the 1994 Northridge earthquake had a moment magnitude of 6.7, caused major damage in the Los Angeles area, occurred at below the Earth's surface, but did not cause surface ...
