2019 Istanbul earthquake was a 5.8 magnitude earthquake that rocked the south-west of Istanbul on 26 September 2019 at 13:59 local time. [8]
One person died due to a heart attack and 43 people were injured. [6] The earthquake was felt in Istanbul, Tekirdağ, Kırklareli, Kocaeli and Sakarya. [5]
North Anatolian Fault system is a strike-slip fault system located in the northern side of Anatolian Plate, which lies between relatively stationary Eurasian Plate in the north and the Arabian Plate in the south. Approximately 1500 km in length, the North Anatolian fault system passes about 20 kilometers south of Istanbul. Strong earthquakes occur at certain intervals along the fault.
The last large earthquakes in the fault system happened in 1999. In 17 August the earthquake in İzmit (7.4 Mw) killed 17.480 people. In 12 November, another earthquake in the nearby city of Düzce (7.2 Mw) killed 845 and injured 4.948. [9]
Many seismologist agree that there is a very high chance for a 7 or higher magnitude earthquake before 2030; which will be caused by the breaking of the North Anatolian fault line under Marmara Sea, just south of Istanbul. [10] [11] [12] [13]
Three days before the main earthquake, on 23 September, there was a 4.6-degree shock in the south-west of Istanbul. [14] Two hours before the earthquake, at 12:00 noon, a 2.9 earthquake took place in Silivri.
The earthquake happened at 13:59 local time at the western edge of the Kumburgaz section of North Anatolian Fault under the Sea of Marmara, at a depth of 6.99 km [3] as a strike-slip movement. [15] Different sources states the magnitude as 5.7 Mw [1] and 5.8 ML. [2]
Over 300 aftershocks were reported after the main earthquake. [16] [17]
Schools and hospitals were evacuated after the earthquake. Governor of Istanbul Ali Yerlikaya announced the schools were closed for the day. AFAD suggested not to enter to the damaged buildings. A 4.1 magnitude aftershock was reported 25 minutes after the main shock. [14]
The first announcement by the President Recep Tayyip Erdoğan stated 8 injured. [18] [19] Later announcements stated a total of 43 injured mostly from panic, and one person with known heart illness dead due to a heart attack. [6]
188 aftershocks with maximum magnitude of 4.1 were recorded after the earthquake. [7] A total of 473 buildings were reported as damaged to AFAD. [7]
A minaret of Avcılar Hacı Ahmet Tükenmez mosque collapsed. [5] Three protected old buildings were damaged in Balat, and later demolished by the municipality later in the day. [5] Take-offs and landings to Sabiha Gökçen Airport were temporarily halted, but flight operations resumed after the runway was checked for potential damage and deemed safe. [5]
AFAD reported damage to walls of the city near İstanbul Biruni University, cracks in some buildings in some neighborhoods, damage in two buildings in Sultangazi and Eyüp, and evacuation of a building in Şirinevler. [3]
Mobile phone coverage of Türk Telekom, Turkcell, and Vodafone were interrupted nationwide for some time after the earthquake, while mobile internet services and landlines were not affected. [20] [21]
The North Anatolian Fault (NAF) 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 1200−1500 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.
The 1999 İzmit earthquake had a moment magnitude of 7.6 and struck Kocaeli Province, Turkey on 17 August. Between 17,127 and 18,373 people died as a result, and the damage was estimated at US $6.5 billion. It was named for the epicenter's proximity to the northwestern city of İzmit. The earthquake occurred at 03:01 local time at a shallow depth of 15 km (9.3 mi). A maximum Mercalli intensity of X (Extreme) was observed. The earthquake lasted for 37 seconds, causing seismic damage, and is widely remembered as one of the deadliest natural disasters in modern Turkish history.
The 1855 Bursa earthquake occurred on 28 February, with an estimated magnitude of 7.02±0.64 Mw A devastating precursor quake that took place in Mustafakemalpaşa, a town of Bursa Province, in Turkey caused severe destruction all over Bursa and other neighboring cities. 300 people died and thousands of homes and workplaces were wrecked, and some of the historical monuments and buildings including mosques collapsed. Subsequently, fire spread out in the city, which increased the death toll.
The 1509 Constantinople earthquake or historically Kıyamet-i Sugra occurred in the Sea of Marmara on 10 September 1509 at about 22:00. The earthquake had an estimated magnitude of 7.2 ± 0.3 on the surface-wave magnitude scale. A tsunami and 45 days of aftershocks followed the earthquake. The death toll of this earthquake is poorly known; estimates range between 1,000 and 13,000.
The 1903 Manzikert earthquake struck Manzikert of nowadays Muş Province in eastern Turkey on 28 April. Registering a surface wave magnitude of 7.0, the earthquake originated from a highly active seismic zone. It killed 3,500 people and 20,000 animals, destroyed 12,000 homes, and is now listed among Turkey's deadliest earthquakes in recorded history. To this day, Turkey is threatened by major earthquakes – more than 100 earthquakes over 7.0 have taken place in the country's known history.
The 2011 Kütahya earthquake struck near a populous region of western Turkey at 23:15 EEST (20:15 UTC) on 19 May with a moment magnitude of 5.8 and a maximum Mercalli intensity of VII. With an epicenter just to the east of Simav, it occurred at an estimated depth of 9.1 kilometers (5.7 mi), resulting in strong shaking in much of Kütahya.
