1668 North Anatolia Earthquake
Northern Anatolia was struck by a large earthquake on 17 August 1668 in the late morning. It had an estimated magnitude in the range 7.8–8.0 and the maximum felt intensity was IX on the Modified Mercalli intensity scale. The epicenter of the earthquake was on the southern shore of Ladik Lake. It caused widespread damage from at least Bolu in the west to Erzincan in the east and resulted in about 8,000 deaths. It remains the most powerful earthquake recorded in Turkey. Tectonic setting North Anatolia lies across the mainly transform boundary between the Anatolian Plate and the Eurasian Plate. Relative to the Eurasian Plate the Anatolian Plate is being forced westwards by the continuing northward movement of the Arabian Plate. This motion is accommodated by a major dextral (right lateral) strike-slip fault system, the North Anatolian Fault. This long structure extends from the Karlıova Triple Junction in the east to the Aegean Sea in the west. In detail the fault is formed ...

North Anatolian Fault
The North Anatolian Fault (NAF) ( tr, Kuzey Anadolu Fay Hattı) is an active right-lateral strike-slip fault in northern Anatolia, and is the transform boundary between the Eurasian Plate and the Anatolian Plate. The fault extends westward from a junction with the East Anatolian Fault at the Karliova Triple Junction in eastern Turkey, across northern Turkey and into the Aegean Sea for a length of 1500 kilometers. It runs about 20 km south of Istanbul. The North Anatolian Fault is similar in many ways to the San Andreas Fault in California. Both are continental transforms with similar lengths and slip rates. The Sea of Marmara near Istanbul is an extensional basin similar to the Salton Trough in California, where a releasing bend in the strike-slip system creates a pull-apart basin. Significant earthquakes Since the disastrous 1939 Erzincan earthquake, there have been seven earthquakes measuring over 7.0 in magnitude, each happening at a point progressively further w ...

Karlıova Triple Junction
The Karlıova Triple Junction is a geologic triple junction of three tectonic plates: the Anatolian Plate, the Eurasian Plate and the Arabian Plate. The Karlıova Triple Junction is found where the east-west trending North Anatolian Fault intersects the East Anatolian Fault coming up from the southwest. Because each arm of the junction is a transform fault A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduct ...

Samsun Castle
Samsun Castle was a castle in Samsun, Turkey. Built on the seaside in 1092, it was demolished between 1909 and 1918. History The castle was built near the Black Sea coast by Danishmends in 1092 after they were unable to capture the Amisos Castle. The castle with -high walls hosted hundreds of houses and shops, two masdjids (small mosque) and a mosque commissioned by Hızır Bey, a commander of the Seljuk Empire. Ottoman traveler Evliya Çelebi wrote after his visit to Samsun in 1640 in his comprehensive work '' Seyahatname'' ("Travelogue") that the castle was strong but damaged. It consisted of walls five thousand steps in length, seventy watchtowers and two thousand battlements. The castle hosted a mosque, a Turkish bath and a small shopping center. The walls and towers of the castle were damaged and some parts of the structure were demolished in the 1668 North Anatolia earthquake which had a magnitude of 8.0. The castle walls on the seaside were reinforced by abutments at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably ...

Merzifon
Merzifon ( hy, Մարզուան, Marzvan, Middle Persian: ; grc, Μερσυφὼν, Mersyphòn, el, Μερζιφούντα, Merzifounta) is a town and district in Amasya Province in the central Black Sea region of Turkey. It covers an area of , and the population (2020) is 73,849 of which 57,900 live in the town of Merzifon, the remainder spread throughout the surrounding countryside. The mayor is Alp Kargı ( CHP). Modern Merzifon is a typical large but quiet Anatolian town with schools, hospitals, courts and other important infrastructure but few cultural amenities. There is a large airbase nearby. Merzifon is twinned with the city of Pleasant Hill, California. Etymology Former variants of its name include Marzifūn, Mersivan, Marsovan, Marsiwān, Mersuvan, Merzpond and Merzban. The name apparently comes from Marzban, the Persian title for a "march lord" or a district governor, although the exact connection is not clear. Scholar Özhan Öztürk claims that original name w ...

2001 Kunlun Earthquake
The 2001 Kunlun earthquake also known as the 2001 Kokoxili earthquake, occurred on 14 November 2001 at 09:26 UTC (17:26 local time), with an epicenter near Kokoxili, close to the border between Qinghai and Xinjiang in a remote mountainous region. With a magnitude of 7.8 Mw (8.0 ), it was the most powerful earthquake in China for 5 decades. No casualties were reported, presumably due to the very low population density and the lack of high-rise buildings. This earthquake was associated with the longest surface rupture ever recorded on land, ~450 km. Tectonic setting The Kunlun fault is one of the major sinistral strike-slip structures that accommodate the eastward motion of the Tibetan Plateau relative to the Eurasian Plate. This motion is caused by the lateral spreading of the zone of thickened crust associated with the collision between the Indian and Eurasian Plates. Earthquake The earthquake rupture began on a relatively small strike-slip fault segment at the weste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niksar
Niksar, historically known as Neocaesarea (Νεοκαισάρεια), is a city in Tokat Province, Turkey. It was settled by many empires, being once the capital city of the province. Niksar is known as "Çukurova of the North-Anatolia" due to its production of many kinds of fruits and vegetables except citrus fruits. On May 2, 2018, Niksar was included in the World Heritage tentative list. History Niksar has been ruled by the Hittite, Persian, Greek, Pontic, Roman, Byzantine, Danishmend, Seljuk and Ottoman Empires. It has always been an important place in Anatolia because of its location, climate and productive farmland. It was known as Cabira in the Hellenistic period ( in Greek). It was one of the favourite residences of Mithridates the Great, who built a palace there, and later of King Polemon I and his successors.Catholic Encyclopedia, 1907, ''s.v.'' Neocaesarea In 72 or 71 BCE, the Battle of Cabira during the Third Mithridatic War took place at Cabira, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stepover (topography)
The step over (also known as the ''pedalada'', the ''denílson'', or the ''scissors'', or the ''roeder shuffle'') is a dribbling move, or feint, in association football, used to fool a defensive player into thinking the offensive player, in possession of the ball, is going to move in a direction they do not intend to move in. According to one source, the move was invented by Argentine striker Pedro Calomino in the early 1900s, and was first used in Europe by Dutch player Law Adam, who was famous for it in the late 1920s/early 1930s, which earned him the nickname "Adam the Scissorsman". It was later also used in Italy by Amedeo Biavati in the 1930s and was used by former Newcastle United player Glenn Roeder in the 1980s. The step over was popularised in the mid-1990s by Brazilian footballer and global superstar Ronaldo. Nowadays, the technique is in widespread use by attacking players all over the world, such as Cristiano Ronaldo and Neymar Neymar da Silva Santos Júnior ...

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 patte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tokat
Tokat is the capital city of Tokat Province of Turkey in the mid- Black Sea region of Anatolia. It is located at the confluence of the Tokat River (Tokat Suyu) with the Yeşilırmak. In the 2018 census, the city of Tokat had a population of 155,000. History The city was established in the Hittite era. During the time of King Mithradates VI of Pontus, it was one of his many strongholds in Asia Minor. Known as Evdokia or Eudoxia, ecclesiastically it was later incorporated into the western part of the Byzantine Greek Empire of Trebizond. Some authors like Guillaume de Jerphanion and William Mitchell Ramsay identified Tokat with the ancient and medieval Dazimon, with Ramsay saying, "Dazimon, which seems to have been a fortress, must have been the modern Tokat, with its strong castle. Henri Grégoire, on the other hand, refuted this as implausible, because a 13th-century text written by Ibn Bibi clearly distinguishes Dazimon and Tokat as separate places. Instead, he said, ...

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] |
