Ottoman Empire
–
After 1354, the Ottomans crossed into Europe, and with the conquest of the Balkans the Ottoman Beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror, at the beginning of the 17th century the empire contained 32 provinces and numerous vassal states. Some of these were later absorbed into the Ottoman Empire, while others were granted various types of autonomy during the course of centuries. With Constantinople as its capital and control of lands around the Mediterranean basin, while the empire was once thought to have entered a period of decline following the death of Suleiman the Magnificent, this view is no longer supported by the majority of academic historians. The empire continued to maintain a flexible and strong economy, society, however, during a long period of peace from 1740 to 1768, the Ottoman military system fell behind that of their European rivals, the Habsburg and Russian Empires. While the Empire was able to hold its own during the conflict, it was struggling with internal dissent. Starting before World War I, but growing increasingly common and violent during it, major atrocities were committed by the Ottoman government against the Armenians, Assyrians and Pontic Greeks. The word Ottoman is an anglicisation of the name of Osman I. Osmans name in turn was the Turkish form of the Arabic name ʿUthmān, in Ottoman Turkish, the empire was referred to as Devlet-i ʿAlīye-yi ʿOsmānīye, or alternatively ʿOsmānlı Devleti. In Modern Turkish, it is known as Osmanlı İmparatorluğu or Osmanlı Devleti, the Turkish word for Ottoman originally referred to the tribal followers of Osman in the fourteenth century, and subsequently came to be used to refer to the empires military-administrative elite. In contrast, the term Turk was used to refer to the Anatolian peasant and tribal population, the term Rūmī was also used to refer to Turkish-speakers by the other Muslim peoples of the empire and beyond. In Western Europe, the two names Ottoman Empire and Turkey were often used interchangeably, with Turkey being increasingly favored both in formal and informal situations and this dichotomy was officially ended in 1920–23, when the newly established Ankara-based Turkish government chose Turkey as the sole official name. Most scholarly historians avoid the terms Turkey, Turks, and Turkish when referring to the Ottomans, as the power of the Seljuk Sultanate of Rum declined in the 13th century, Anatolia was divided into a patchwork of independent Turkish principalities known as the Anatolian Beyliks. One of these beyliks, in the region of Bithynia on the frontier of the Byzantine Empire, was led by the Turkish tribal leader Osman, osmans early followers consisted both of Turkish tribal groups and Byzantine renegades, many but not all converts to Islam. Osman extended the control of his principality by conquering Byzantine towns along the Sakarya River and it is not well understood how the early Ottomans came to dominate their neighbours, due to the scarcity of the sources which survive from this period. One school of thought which was popular during the twentieth century argued that the Ottomans achieved success by rallying religious warriors to fight for them in the name of Islam, in the century after the death of Osman I, Ottoman rule began to extend over Anatolia and the Balkans. Osmans son, Orhan, captured the northwestern Anatolian city of Bursa in 1326 and this conquest meant the loss of Byzantine control over northwestern Anatolia. The important city of Thessaloniki was captured from the Venetians in 1387, the Ottoman victory at Kosovo in 1389 effectively marked the end of Serbian power in the region, paving the way for Ottoman expansion into Europe

Tsunami
–
A tsunami or tidal wave, also known as a seismic sea wave, is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Unlike normal ocean waves which are generated by wind, or tides which are generated by the pull of the Moon and Sun. Tsunami waves do not resemble normal undersea currents or sea waves, Tsunamis generally consist of a series of waves with periods ranging from minutes to hours, arriving in a so-called internal wave train. Wave heights of tens of metres can be generated by large events, numerous terms are used in the English language to describe waves created in a body of water by the displacement of water, however, none of the terms in frequent use are entirely accurate. The term tsunami, meaning harbour wave in literal translation, comes from the Japanese 津波, while not entirely accurate, as tsunami are not restricted to harbours, tsunami is currently the term most widely accepted by geologists and oceanographers. Tsunami are sometimes referred to as tidal waves and this once-popular term derives from the most common appearance of tsunami, which is that of an extraordinarily high tidal bore. Although the meanings of tidal include resembling or having the form or character of the tides, use of the tidal wave is discouraged by geologists. The term seismic sea wave also is used to refer to the phenomenon, prior to the rise of the use of the term tsunami in English-speaking countries, scientists generally encouraged the use of the term seismic sea wave rather than tidal wave. The Sumatran region is not unused to tsunamis either, with earthquakes of varying magnitudes regularly occurring off the coast of the island, Tsunamis are an often underestimated hazard in the Mediterranean Sea and parts of Europe. The tsunami claimed more than 123,000 lives in Sicily, the Storegga Slide in the Norwegian sea and some examples of tsunamis affecting the British Isles refer to landslide and meteotsunamis predominantly and less to earthquake-induced waves. The cause, in my opinion, of this phenomenon must be sought in the earthquake, at the point where its shock has been the most violent the sea is driven back, and suddenly recoiling with redoubled force, causes the inundation. Without an earthquake I do not see how such an accident could happen, the principal generation mechanism of a tsunami is the displacement of a substantial volume of water or perturbation of the sea. This displacement of water is attributed to either earthquakes, landslides, volcanic eruptions, glacier calvings or more rarely by meteorites. The waves formed in this way are then sustained by gravity, tides do not play any part in the generation of tsunamis. Tsunami can be generated when the sea floor abruptly deforms and vertically displaces the overlying water and they grow in height when they reach shallower water, in a wave shoaling process described below. A tsunami can occur in any state and even at low tide can still inundate coastal areas. On April 1,1946, the 8.6 Mw Aleutian Islands earthquake occurred with a maximum Mercalli intensity of VI and it generated a tsunami which inundated Hilo on the island of Hawaii with a 14-metre high surge. Between 165 and 173 were killed, the area where the earthquake occurred is where the Pacific Ocean floor is subducting under Alaska

Fault (geology)
–
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 movement. Large faults within the Earths crust result from the action of tectonic forces. Energy release associated with movement on active faults is the cause of most earthquakes. A fault plane is the plane that represents the surface of a fault. A fault trace or fault line is the intersection of a plane with the ground surface. A fault trace is also the line commonly plotted on maps to represent a fault. Since faults do not usually consist of a single, clean fracture, the two sides of a non-vertical fault are known as the hanging wall and footwall. By definition, the wall occurs above the fault plane. This terminology comes from mining, when working a tabular ore body, because of friction and the rigidity of rocks, they cannot glide or flow past each other easily, and occasionally all movement stops. A fault in ductile rocks can also release instantaneously when the rate is too great. The energy released by instantaneous strain-release causes earthquakes, a common phenomenon along transform boundaries, slip is defined as the relative movement of geological features present on either side of a fault plane, and is a displacement vector. A faults sense of slip is defined as the motion of the rock on each side of the fault with respect to the other side. In practice, it is only possible to find the slip direction of faults. Based on direction of slip, faults can be categorized as, strike-slip. Dip-slip, offset is predominantly vertical and/or perpendicular to the fault trace, oblique-slip, combining significant strike and dip slip. The fault surface is usually vertical and the footwall moves either left or right or laterally with very little vertical motion. Strike-slip faults with left-lateral motion are known as sinistral faults. Those with right-lateral motion are known as dextral faults

Istanbul
–
Istanbul, historically known as Constantinople and Byzantium, is the most populous city in Turkey and the countrys economic, cultural, and historic center. Istanbul is a city in Eurasia, straddling the Bosphorus strait between the Sea of Marmara and the Black Sea. Its commercial and historical center lies on the European side and about a third of its population lives on the Asian side, the city is the administrative center of the Istanbul Metropolitan Municipality, both hosting a population of around 14.7 million residents. Istanbul is one of the worlds most populous cities and ranks as the worlds 7th-largest city proper, founded under the name of Byzantion on the Sarayburnu promontory around 660 BCE, the city developed to become one of the most significant in history. After its reestablishment as Constantinople in 330 CE, it served as a capital for almost 16 centuries, during the Roman and Byzantine, the Latin. Overlooked for the new capital Ankara during the period, the city has since regained much of its prominence. The population of the city has increased tenfold since the 1950s, as migrants from across Anatolia have moved in, arts, music, film, and cultural festivals were established at the end of the 20th century and continue to be hosted by the city today. Infrastructure improvements have produced a complex transportation network, considered a global city, Istanbul has one of the fastest-growing metropolitan economies in the world. It hosts the headquarters of many Turkish companies and media outlets and accounts for more than a quarter of the gross domestic product. Hoping to capitalize on its revitalization and rapid expansion, Istanbul has bid for the Summer Olympics five times in twenty years, the first known name of the city is Byzantium, the name given to it at its foundation by Megarean colonists around 660 BCE. The name is thought to be derived from a personal name, ancient Greek tradition refers to a legendary king of that name as the leader of the Greek colonists. Modern scholars have hypothesized that the name of Byzas was of local Thracian or Illyrian origin. He also attempted to promote the name Nova Roma and its Greek version Νέα Ῥώμη Nea Romē, the use of Constantinople to refer to the city during the Ottoman period is now considered politically incorrect, even if not historically inaccurate, by Turks. By the 19th century, the city had acquired other names used by foreigners or Turks. Europeans used Constantinople to refer to the whole of the city, pera was used to describe the area between the Golden Horn and the Bosphorus, but Turks also used the name Beyoğlu. The name İstanbul is commonly held to derive from the Medieval Greek phrase εἰς τὴν Πόλιν and this reflected its status as the only major city in the vicinity. The importance of Constantinople in the Ottoman world was reflected by its Ottoman name Der Saadet meaning the gate to Prosperity in Ottoman. An alternative view is that the name evolved directly from the name Constantinople, with the first, a Turkish folk etymology traces the name to Islam bol plenty of Islam because the city was called Islambol or Islambul as the capital of the Islamic Ottoman Empire

Fatih Mosque, Istanbul
–
The Fatih Mosque is an Ottoman mosque in the Fatih district of Istanbul, Turkey. The original mosque on the site was constructed between 1463 to 1470 and it was seriously damaged in the 1766 earthquake and was rebuilt in 1771 to a different design. It is one of the largest examples of Turkish-Islamic architecture in Istanbul and it is named after Ottoman sultan Mehmed the Conqueror, known in Turkish as Fatih Sultan Mehmed, the Ottoman sultan who conquered Constantinople in 1453. The Fatih mosque complex was a religious and social building of unprecedented size and it was built by the Greek architect Atik Sinan. The Fatih mosque was the first monumental project in the Ottoman imperial architectural tradition, the original complex included a set of well-planned buildings constructed around the mosque. They include eight medrese, library, hospital, hospice, caravanserai, market, hamam, primary school, various türbe were added at a later dates. The original complex covered an almost square area 325 metres on a side, the original mosque was badly damaged in the 1509 earthquake, after that it was repaired, but was then damaged again by earthquakes in 1557 and 1754 and repaired yet again. It was then destroyed by an earthquake on 22 May 1766 when the main dome collapsed. The current mosque was completed in 1771 under Sultan Mustafa III by the architect, the first Fatih mosque had one central dome supported by a single semi-dome of the same diameter on the qibla side and suspended on four arches, its dome was 26 meter in diameter. The second mosque which was built by Sultan Mustafa III after the 1766 earthquake, was built on a square plan and it has one central dome supported by four semi-domes. The courtyard, main portal and lower portions of the minarets remain from the original construction. The present interior of the Fatih Mosque is essentially a copy of earlier designs invented by Sinan re-used repeatedly by himself, the 26 meter diameter center dome is supported by four semi-domes on each axis supported by four large marble columns. There are two each with twin galleries. The mihrab dates from the original construction, as with other imperial mosques in Istanbul, the Fatih Mosque was designed as a kulliye, or complex with adjacent structures to service both religious and cultural needs. To the north and south of the mosque are the Sahn-ı Seman, eight great medrese and these buildings are symmetrical, and each contains 18 cells for students and a dershane. Behind each was an annex, about half as large as the medrese itself, the medreses provided for about a thousand students, making it a large university for its time. The Hospice is outside the southeast corner of the mosque precincts, the building has a beautiful courtyard supported by 16 exceptional columns of verd antique and granite, which were probably salvaged from the Church of the Holy Apostles. Opposite the hospice is the large türbe of Sultan Mahmud IIs mother, in the graveyard on the kiblah side behind the mosque are the türbe of Sultan Mehmet II and his wife Gulbahar Hatun

Galata
–
Galata was a neighbourhood opposite Constantinople, located at the northern shore of the Golden Horn, the inlet which separates it from the historic peninsula of old Constantinople. The Golden Horn is crossed by bridges, most notably the Galata Bridge. The medieval citadel of Galata was a colony of the Republic of Genoa between 1273 and 1453, the famous Galata Tower was built by the Genoese in 1348 at the northernmost and highest point of the citadel. At present, Galata is a quarter within the borough of Beyoğlu in Istanbul, there are several theories concerning the origin of the name Galata. In historic documents, Galata is often called Pera, which comes from the old Greek name for the place, Peran en Sykais, the quarter first appears in Late Antiquity as Sykai or Sycae. By the time the Notitia Urbis Constantinopolitanae was compiled in ca.425 AD, according to the Notitia, it featured public baths and a forum built by Emperor Honorius, a theatre, a porticoed street and 435 mansions. It is also probable that the settlement was enclosed by walls in the 5th century, Sykai received full city rights under Justinian I, who renamed it Iustinianopolis, but declined and was probably abandoned in the 7th century. Only the large tower, Megalos Pyrgos which controlled the northern end of the sea chain that blocked the entrance to the Golden Horn remained, in the 11th century, the quarter housed the citys Jewish community, which came to number some 2,500 people. In 1171, a new Genoese settlement in the area was attacked, the kastellion and the Jewish quarter were seized and destroyed in 1203 by the Catholic crusaders during the Fourth Crusade, shortly before the sack of Constantinople. In 1233, during the subsequent Latin Empire, a small Catholic chapel dedicated to St. Paul was built in place of a 6th-century Byzantine church in Galata. In 1407, Pope Gregory XII, in order to ensure the maintenance of the church, in 1261, the quarter was retaken by the Byzantines, but Emperor Michael VIII Palaiologos granted it to the Genoese in 1267 in accordance with the Treaty of Nymphaeum. The precise limits of the Genoese colony were stipulated in 1303, the Genoese however disregarded this, and through subsequent expansions of the walls, enlarged the area of their settlement. At present, only a portion of the Genoese walls are still standing. Bankalar Caddesi has rows of Ottoman-era bank buildings, including the headquarters of the Ottoman Central Bank, several ornaments that were originally on the facade of the Genoese Palace were used to embellish these 19th-century bank buildings in the late Ottoman period. The seaside mansion of the Camondo family, popularly known as the Camondo Palace, was built between 1865 and 1869 and designed by architect Sarkis Balyan and it is located on the northern shore of the Golden Horn, within the nearby Kasımpaşa quarter to the west of Galata. It later became the headquarters of the Ministry of the Navy during the late Ottoman period, Galatasaray S. K. Galatasaray literally means Galata Palace.

Bayezid II Mosque
–
The Bayezid II Mosque is an Ottoman imperial mosque located in the Beyazıt Square area of Istanbul, Turkey, near the ruins of the Forum of Theodosius of ancient Constantinople. The Beyazidiye Camii was commissioned by Ottoman Sultan Bayezid II, and was the large imperial mosque complex to be erected in Istanbul after the conquest. That the architect was a nephew of the Greek architect of the Fatih Mosque, is known from a grant of Bayazid II, the surrounding külliye complex, date from 1501 to 1506. The dome was rebuilt after an earthquake in 1509. The minarets burned separately in 1683 and 1764, an inscription above the courtyard entrance suggests that repairs were also conducted in 1767. The mosque is oriented along the northwest-southeast axis with a courtyard to the northwest with an area almost equal to that of the mosque itself, the courtyard has monumental entrance portals on each side. The mosque itself is approximately 40 metres square, with a 17-metre diameter dome, the design is that of a central dome held by semi-domes on all four sides. The mosque is constructed entirely of cut stone appropriating colored stones and marbles appropriated from nearby Byzantine ruins, the interior of the mosque is patterned after the Hagia Sophia on a smaller scale. The dome is supported by rectangular piers, with smooth pendentives. The space is lit with twenty windows at the base of the dome and seven windows on each semi-dome, on the west side, a broad extended corridor extends considerable beyond the main structure of the building. At the ends of wings are the two minarets. Behind the mosque is a garden, containing the türbe of Sultan Bayezid II, his daughter Selçuk Hatun. Below the garden is an arcade of shops whose rents were intended to support the mosque. This arcade was designed by Mimar Sinan in 1580 and extensively restored in the 1960s, the former public kitchens of the mosque was converted into the State Library of Istanbul by Sultan Abdulhamid II in 1882 and houses over 120,000 books and 7000 manuscripts.

Minaret
–
A minaret, from Arabic, منارة manāra, lit. lighthouse, also known as Goldaste, is a distinctive architectural structure akin to a tower and typically found adjacent to mosques. Generally a tall spire with a conical or onion-shaped crown, usually either free-standing or taller than associated support structure, the basic form of a minaret includes a base, shaft, and gallery. Styles vary regionally and by period, minarets provide a visual focal point and are traditionally used for the Muslim call to prayer. The purpose of minarets in traditional Eastern region architecture is to serve as a system for a building in very hot climates. That buildings of middle eastern origins have such outstanding features is architecturally intentional, however in modern times, with the invention of the modern air conditioners, the purpose of minarets has changed to traditional symbol. The minaret would be equipped with a speaker that would call people to prayers in Muslim countries. In addition to providing a visual cue to a Muslim community, the call to prayer is issued five times each day, dawn, noon, mid-afternoon, sunset, and night. In most modern mosques, the adhān is called from the musallah via microphone to a system on the minaret. Around 80 years after Muhammads death, the first known minarets appeared, minarets have been described as the gate from heaven and earth, and as the Arabic language letter aleph. The massive minaret of the Great Mosque of Kairouan in Tunisia is the oldest standing minaret and its construction began during the first third of the 8th century and was completed in 836 CE. The imposing square-plan tower consists of three sections of decreasing size reaching 31.5 meters, considered as the prototype for minarets of the western Islamic world, it served as a model for many later minarets. The tallest minaret, at 210 metres is located at the Hassan II Mosque in Casablanca, the tallest brick minaret is Qutub Minar located in Delhi, India. In some of the oldest mosques, such as the Great Mosque of Damascus, the basic form of minarets consists of three parts, a base, shaft, and a gallery. For the base, the ground is excavated until a foundation is reached. Gravel and other supporting materials may be used as a foundation, minarets may be conical, square, cylindrical, or polygonal. Stairs circle the shaft in a fashion, providing necessary structural support to the highly elongated shaft. The gallery is a balcony that encircles the upper sections from which the muezzin may give the call to prayer, styles and architecture can vary widely according to region and time period. Here are a few styles and the localities from which they derive, Tunisia Quadrangular, turkish 1,2,4 or 6 minarets related to the size of the mosque

Hagia Sophia
–
Hagia Sophia was a Greek Orthodox Christian patriarchal basilica, later an imperial mosque, and now a museum in Istanbul, Turkey. The building was converted into an Ottoman mosque from 29 May 1453 until 1931. It was then secularized and opened as a museum on 1 February 1935, famous in particular for its massive dome, it is considered the epitome of Byzantine architecture and is said to have changed the history of architecture. It remained the worlds largest cathedral for nearly a thousand years and it was designed by the Greek geometers Isidore of Miletus and Anthemius of Tralles. The church contained a collection of relics and featured, among other things. In 1453, Constantinople was conquered by the Ottoman Empire under Mehmed the Conqueror, by that point, the church had fallen into a state of disrepair. Nevertheless, the Christian cathedral made an impression on the new Ottoman rulers. Islamic features—such as the mihrab, minbar, and four minarets—were added and it remained a mosque until 1931, when it was closed to the public for four years. It was re-opened in 1935 as a museum by the Republic of Turkey, Hagia Sophia was, as of 2014, the second-most visited museum in Turkey, attracting almost 3.3 million visitors annually. According to data released by the Turkish Culture and Tourism Ministry, from its initial conversion until the construction of the nearby Sultan Ahmed Mosque in 1616, it was the principal mosque of Istanbul. The first church on the site was known as the Μεγάλη Ἐκκλησία, or in Latin Magna Ecclesia, inaugurated on 15 February 360 by the Arian bishop Eudoxius of Antioch, it was built next to the area where the imperial palace was being developed. The nearby Hagia Eirene church was completed earlier and served as cathedral until the Great Church was completed, both churches acted together as the principal churches of the Byzantine Empire. Writing in 440, Socrates of Constantinople claimed that the church was built by Constantius II, a tradition which is not older than the 7th or 8th century, reports that the edifice was built by Constantine the Great. Zonaras reconciles the two opinions, writing that Constantius had repaired the edifice consecrated by Eusebius of Nicomedia, after it had collapsed. Since Eusebius was bishop of Constantinople from 339 to 341, and Constantine died in 337, the edifice was built as a traditional Latin colonnaded basilica with galleries and a wooden roof. It was preceded by an atrium and it was claimed to be one of the worlds most outstanding monuments at the time. The Patriarch of Constantinople John Chrysostom came into a conflict with Empress Aelia Eudoxia, wife of the emperor Arcadius, during the subsequent riots, this first church was largely burned down. Nothing remains of the first church today, a second church on the site was ordered by Theodosius II, who inaugurated it on 10 October 415

Byzantine Empire
–
It survived the fragmentation and fall of the Western Roman Empire in the 5th century AD and continued to exist for an additional thousand years until it fell to the Ottoman Turks in 1453. During most of its existence, the empire was the most powerful economic, cultural, several signal events from the 4th to 6th centuries mark the period of transition during which the Roman Empires Greek East and Latin West divided. Constantine I reorganised the empire, made Constantinople the new capital, under Theodosius I, Christianity became the Empires official state religion and other religious practices were proscribed. Finally, under the reign of Heraclius, the Empires military, the borders of the Empire evolved significantly over its existence, as it went through several cycles of decline and recovery. During the reign of Maurice, the Empires eastern frontier was expanded, in a matter of years the Empire lost its richest provinces, Egypt and Syria, to the Arabs. This battle opened the way for the Turks to settle in Anatolia, the Empire recovered again during the Komnenian restoration, such that by the 12th century Constantinople was the largest and wealthiest European city. Despite the eventual recovery of Constantinople in 1261, the Byzantine Empire remained only one of several small states in the area for the final two centuries of its existence. Its remaining territories were annexed by the Ottomans over the 15th century. The Fall of Constantinople to the Ottoman Empire in 1453 finally ended the Byzantine Empire, the term comes from Byzantium, the name of the city of Constantinople before it became Constantines capital. This older name of the city would rarely be used from this point onward except in historical or poetic contexts. The publication in 1648 of the Byzantine du Louvre, and in 1680 of Du Canges Historia Byzantina further popularised the use of Byzantine among French authors, however, it was not until the mid-19th century that the term came into general use in the Western world. The Byzantine Empire was known to its inhabitants as the Roman Empire, the Empire of the Romans, Romania, the Roman Republic, Graikia, and also as Rhōmais. The inhabitants called themselves Romaioi and Graikoi, and even as late as the 19th century Greeks typically referred to modern Greek as Romaika and Graikika. The authority of the Byzantine emperor as the legitimate Roman emperor was challenged by the coronation of Charlemagne as Imperator Augustus by Pope Leo III in the year 800. No such distinction existed in the Islamic and Slavic worlds, where the Empire was more seen as the continuation of the Roman Empire. In the Islamic world, the Roman Empire was known primarily as Rûm, the Roman army succeeded in conquering many territories covering the entire Mediterranean region and coastal regions in southwestern Europe and north Africa. These territories were home to different cultural groups, both urban populations and rural populations. The West also suffered heavily from the instability of the 3rd century AD
