It is remarkable that the epicentres of earthquakes during the 10th century were moving from west to east, while the direction appears to be reversed this century, from east to west Fig. Note that the epicentre was very close to Izmit Bay. Throughout known history, many major earthquakes have occurred along virtually the entire length of the Izmit earthquake 1999 Anatolian fault.
Offsets along the rupture were as large as 5. Migration of Epicentres and Ruptures during the last Millennium. United States Geological Survey Added by: As much as 5 meters of right-lateral strike-slip displacement occurred along a km zone of the North Anatolian Fault between Karamursel and Golyaka.
The following figures 7 and 8 demonstrate the sheer destructive power of the earthquake on buildings and devastating impact on human life, both material and psychological.
The source of this shock is calculated to be equivalent to 7, Kilotons of TNT, which is close to of the atom bombs dropped over Hiroshima in Coruh, C. Farther west, in Istanbulthe earthquake caused hundreds of fatalities and widespread destruction.
Breakage in water pipelines, results of the quake, nullified attempts at extinguishing the fire. Particularly Izmit earthquake 1999 the last few decades, we have gained a much better understanding of earthquakes, chiefly owing to the concept of Plate Tectonics.
Both have one magnitude 8 shock: Four days after the 7. But while the San Andreas Fault produced three major earthquakes in this century, the North Anatolian fault has suffered twelve such shocks. We have no means of predicting the likelihood of a larger event in this new location.
Previous aftershocks of this size were centered to the east of the mainshock, further from the cities of Bursa and Istanbul. A simplified understanding of the relationship between the colours in the image and the land surface type is as follows: The tsunami caused the deaths of people.
This location indicates that the earthquake occurred on the northernmost strand of the North Anatolian fault system. Modern GPS stations are providing invaluable quantitative information on pre- co- and post-seismic deformation related to earthquakes in active areas.
About the Author s Turgay Ogut holds B. Izmit — Turkey Earthquake On August 17, a magnitude 7. The rescue and relief effort was spearheaded by the Turkish Red Crescent and the Turkish army, with many international aid agencies joining in.
The fire spread over the next few days, warranting the evacuation of the area within three miles of the refinery. The fire was declared under control five days later after claiming at least seventeen tanks and untold amounts of complex piping. The hypocentre of the shock was at a depth of 17 km, approximately half way down to Moho.
Preliminary field reports confirm this type of motion on the fault, and initial field observations indicate that the earthquake produced at least 60 kilometers 37 miles of surface rupture and right-lateral offsets as large as 2. Note the two digit numbers annotated in the figure refer to the year of the earthquake.
Casualties were reported high in the nearby town of Golcuk, Derince and Darica. The initial shock lasted less than a minute and registered a magnitude of 7. Print Introduction Earthquakes are the worst of the natural disasters.
Sheer power of the earthquake on buildings and a big passenger boat pushed to the shore. Learn More in these related Britannica articles: Conclusion Studying earthquakes is very important because they have direct impact on human life.
USGS ShakeMap showing the intensity of the event The following table shows the breakdown of rescue teams by country in the affected locations: Because most of the casualties resulted from the collapse of residential buildings, there was a strong public outcry against private contractors, who were accused of poor workmanship and of using cheap, inadequate materials.
The earthquake originated at a depth of 17 kilometers, or about Earthquake Kocaeli, Turkey, The moment magnitude (M W) Kocaeli, Turkey, earthquake struck the Kocaeli.
