On August 17, 1999 northwest Turkey which has a population of 20 million people or one third of Turkey’s population experienced a powerful earthquake. The quake measured 7.6 magnitude earthquake on the ricker scale. The Izmit earthquake is also known as the Kocaeli or Golcuk earthquake killed 17,000, injured 43,959 and left over half a million homeless.
About the Earthquake:
The earth quake was caused by strain on the tectonic plates. . An earthquake happens when a plate pushes vertically or horizontally as stoves against the earth’s crust. The Izmit quake was caused by a slip fault or a horizontal movement in the plates. The fault trace reached 100km long in a right lateral movement. Turkey lies on a fault line called the North Anatolian fault zone (NAFZ); the NAFZ is squeezed between to other fault lines called the Eurasian plate on the north and African and Arabian plate on the south. All major earthquakes that occur in Turkey are caused by slips along the NAFZ and Eastern Anatolian plate. The Izmit earthquake had a seismic rupture length of 150 km(93 miles) and extended from the city of Duzce to the Sea of Marmama along the Gulf of Izmit. Some of the offsets of the rupture reached 5.7 metres. The origin of the disturbance was 40.702 N and 29.987 E , or around 100 km east of Istanbul. The distance between the epicentre and the hypocentre was 17km. The strength of this earthquake is approximately 1000 of the atom bombs that were dropped over Hiroshima in 1945 or 7,558 Kilotons of TNT. No less then 3 months after the main shock turkey experienced a terrible 7.2 magnitude after shock.
Impact on the community:
The Izmit earthquake hit one of the most populated areas of Turkey. There was an estimated 20,000 buildings and structures damaged, which left over half a million people homeless. The entire country loss power soon after the earthquake because of damage to the central 380 kV substation at Adapazari. Power was returned to most of the...
