1509 Istanbul Earthquake
The 1509 Constantinople earthquake or historically ('Minor Judgment Day') occurred in the Sea of Marmara on 10 September 1509 at about 10 p.m. The earthquake had an estimated magnitude of on the surface wave magnitude scale. A tsunami and forty-five days of aftershocks followed the earthquake. The death toll of this earthquake is poorly known, with estimates in the range of 1,000 to 13,000. Background The Sea of Marmara is a pull-apart basin formed at a releasing bend in the North Anatolian Fault, a right-lateral strike-slip fault. This local zone of extension occurs where this transform boundary between the Anatolian Plate and the Eurasian Plate steps northwards to the west of Izmit from the Izmit Fault to the Ganos Fault. The pattern of faults within the Sea of Marmara basin is complex but near Istanbul there is a single main fault segment with a sharp bend. To the west, the fault trends west–east and is pure strike-slip in type. To the east, the fault is NW-SE tren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Wave Magnitude
The surface wave magnitude (M_s) scale is one of the magnitude scales used in seismology to describe the size of an earthquake. It is based on measurements of Rayleigh surface waves that travel along the uppermost layers of the Earth. This magnitude scale is related to the local magnitude scale proposed by Charles Francis Richter in 1935, with modifications from both Richter and Beno Gutenberg throughout the 1940s and 1950s. It is currently used in People's Republic of China as a national standard (GB 17740-1999) for categorising earthquakes. Recorded magnitudes of earthquakes through the mid 20th century, commonly attributed to Richter, could be either M_s or M_L. Definition The formula to calculate surface wave magnitude is: :M_s = \log_\left(\frac\right)_ + \sigma(\Delta)\,, where A is the maximum particle displacement in surface waves (vector sum of the two horizontal displacements) in μm, T is the corresponding period in s (usually 20 2 seconds), Δ is the epi ...

Çınarcık Basin
The Çınarcık Basin is a submarine tectonic basin located in the Sea of Marmara, in Turkey. Geography The Çınarcık basin gets its name from Çınarcık, a town and district of the Yalova Province in the Marmara region of Turkey. It is the easternmost of the three basins which run in direction EW in the sea, the other two being (from E to W) the central basin and the Tekirdağ basin. Its maximum depth amounts to 1,276 m. Geology The Çınarcık Basin is a transtensional basin which runs along the Princes' Islands segment of the northern branch of the North Anatolian Fault (NAF). However, in correspondence with the basin there is no evidence of a single strike-slip Fault, neither is visible a cross-basin fault or a pure strike-slip fault in correspondence of the northern margin; along the southern and northern edges seismic imaging shows many deep-penetrating faults. The basin hosted the nucleation points of many among the strongest earthquakes of the region, like those of 150 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yoros Castle
Yoros Castle ( tr, Yoros Kalesi) is a ruined castle dating back to Byzantine times that stands above the confluence of the Bosphorus and the Black Sea, to the north of Joshua's Hill, in Beykoz district, Istanbul, Turkey. It is commonly referred to as the Genoese Castle, due to Genoa’s possession of it in the mid-15th century. Geography Yoros Castle sits on a hill surrounded by steep bluffs overlooking the confluence of the Bosphorus and the Black Sea. It is just north of a small fishing village called Anadolu Kavağı, on Macar Bay, and the entire area is referred to as Anadolu Kavağı. The castle overlooks one of the narrowest stretches of the Bosphorus, and on the opposite shore is Rumeli Kavağı, which formerly held a fortification similar to Yoros Castle. ( Anadolu and Rumeli were Ottoman terms for the Anatolian and European parts of the empire). Since 2016 the Third Bosphorus Bridge has been visible from Yoros Castle.

Anadoluhisarı
Anadoluhisarı ( en, Anatolian Castle), known historically as Güzelce Hisar ("the Beauteous Castle") is a medieval Ottoman fortress located in Istanbul, Turkey on the Anatolian (Asian) side of the Bosporus. The complex is the oldest surviving Turkish architectural structure built in Istanbul, and further gives its name to the neighborhood around it in the city's Beykoz district. History Anadoluhisarı was built between 1393 and 1394 on the commission of the Ottoman Sultan Bayezid I, as part of his preparations for a siege on the then-Byzantine city of Constantinople. Constructed on an area of , the fortress is situated at the narrowmost point of the Bosporus, where the strait is a mere wide. The site is bound by Göksu ( grc, Aretòs) creek to the south, and was previously home to the ruins of a Roman temple dedicated to Uranus. Erected primarily as a watch fort, the citadel has a tall, quadratic main tower within the walls of an irregular pentagon, with five watchtowers ...

Rumelihisarı
Rumelihisarı (also known as Rumelian Castle and Roumeli Hissar Castle) or Boğazkesen Castle (meaning " Strait-Blocker Castle" or literally "Throat-Cutter Castle") is a medieval fortress located in Istanbul, Turkey, on a series of hills on the European banks of the Bosphorus. The fortress also lends its name to the immediate neighborhood around it in the city's Sarıyer district. Conceived and built between 1451 and 1452 on the orders of Ottoman Sultan Mehmed II, the complex was commissioned in preparation for a planned Ottoman siege on the then-Byzantine city of Constantinople, with the goal of cutting off maritime military and logistical relief that could potentially come to the Byzantines' aid by way of the Bosphorus Strait, hence the fortress's alternative name, "Boğazkesen", i.e. "Strait-cutter" Castle. Its older sister structure, Anadoluhisari ("Anatolian Fortress"), sits on the opposite banks of the Bosporus, and the two fortresses worked in tandem during the fina ...

Fatih Mosque
The large Fatih Mosque ( tr, Fatih Camii, "Conqueror's Mosque" in English) is an Ottoman mosque off Fevzi Paşa Caddesi in the Fatih district of Istanbul, Turkey. The original mosque was constructed between 1463 and 1470 on the site of the Church of the Holy Apostles. Seriously damaged in the 1766 earthquake, it was rebuilt in 1771 to a different design. It is named after the Ottoman sultan Mehmed the Conqueror, known in Turkish as ''Fatih Sultan Mehmed'', who conquered Constantinople in 1453. The Sahn-ı Seman Medrese, once an important center for the study of theology, law, medicine, astronomy, physics and mathematics, formed part of the Fatih Mosque. It was founded by the Turkic astronomer Ali Qushji who had been invited by Mehmed to his court in Istanbul. The mosque complex was completely restored in 2009 and again ten years later. It reopened to worshippers in 2021. History The Fatih Mosque complex was a religious and social building of unprecedented size and complex ...

Minaret
A minaret (; ar, منارة, translit=manāra, or ar, مِئْذَنة, translit=miʾḏana, links=no; tr, minare; fa, گلدسته, translit=goldaste) is a type of tower typically built into or adjacent to mosques. Minarets are generally used to project the Muslim call to prayer ('' adhan''), but they also served as landmarks and symbols of Islam's presence. They can have a variety of forms, from thick, squat towers to soaring, pencil-thin spires. Etymology Two Arabic words are used to denote the minaret tower: ''manāra'' and ''manār''. The English word "minaret" originates from the former, via the Turkish version (). The Arabic word ''manāra'' (plural: ''manārāt'') originally meant a "lamp stand", a cognate of Hebrew '' menorah''. It is assumed to be a derivation of an older reconstructed form, ''manwara''. The other word, ''manār'' (plural: ''manā'ir'' or ''manāyir''), means "a place of light". Both words derive from the Arabic root ''n-w-r'', which has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bayezid II Mosque, Istanbul
The Bayezid II Mosque ( tr, Beyazıt Camii, Bayezid Camii) is an early 16th-century Ottoman imperial mosque located in Beyazıt Square in Istanbul, Turkey, near the ruins of the Forum of Theodosius of ancient Constantinople. History The Beyazid Mosque was commissioned by the Ottoman Sultan Bayezid II, and was the second large imperial mosque complex (or selatin mosque) to be erected in Istanbul after the conquest in 1453. The earlier imperial complex, the Fatih Mosque, was later destroyed by earthquakes and completely rebuilt in a different style. As a result, the Beyazid complex is the oldest imperial complex in Istanbul that is preserved in more or less its original form, making it of considerable historical and architectural significance.Freely, ''Blue Guide Istanbul'' pp. 151–153 The mosque was constructed between 1500 and 1505, with a ''külliye'' (religious and charitable complex) added immediately afterwards. This included a ''medrese'' (theological college), com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walls Of Constantinople
The Walls of Constantinople ( el, Τείχη της Κωνσταντινουπόλεως) are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul in Turkey) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger. They saved the city, and the Byzantine Empire with it, during sieges by the Avar-Sassanian coalition, Arabs, Rus', and Bulgar ...

Büyükçekmece
Büyükçekmece is a district and municipality in the suburbs of Istanbul, Turkey on the Sea of Marmara coast of the European side, west of the city. It is largely an industrial area with a population of 380,000. The mayor is Hasan Akgün ( CHP). History The land around this inlet of the Sea of Marmara, has been settled, abandoned and resettled throughout history as army after army passed along the coast to the Bosphorus. It is thought to be the site of the Greek colony on the Marmara shore called Athyra (), also known as Athyras. In 443 AD, the armies of Attila the Hun took this settlement and its associated fort, and this was presumably his last conquest of that campaign before turning around. The earliest mention of the bishopric of Athyra in a list of dioceses is of the late 15th century, but a seal has been found of a 10th-century Bishop Orestes of the see. No longer a residential bishopric, Athyra is today listed by the Catholic Church as a titular see. The Ottoman archit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galata
Galata is the former name of the Karaköy neighbourhood in Istanbul, which is located at the northern shore of the Golden Horn. The district is connected to the historic Fatih district by several bridges that cross the Golden Horn, 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. Galata is now a quarter within the district of Beyoğlu in Istanbul. Etymology There are several theories concerning the origin of the name ''Galata''. The Greeks believe that the name comes either from ''Galatai'' (meaning "Gauls"), as the Celtic tribe of Gauls (Galatians) were thought to have camped here during the Hellenistic period before settling into Galatia in central Anatolia; or from ''galatas'' (meaning "milkman"), as the area was used by shepherds for grazing in the Early Medieval (Byzantine) period.
