Ripening found near Istanbul earthquake

June 19, 2013. Geologists have identified a suspicious fracture site under the Sea of Marmara near Istanbul. Analysis of the seismic data has shown that there is already 250 years old is not going aftershocks and this may indicate a threatening earthquake accumulation of stress. Details are papers Nature Communications.

Researchers from Germany, New Zealand and Turkey itself, examined data on past earthquakes near Istanbul. They have taken into account as major earthquakes and small tremors that were fixed only with special equipment, and the result was a white spot south of the city beneath the bottom of the Sea of Marmara. From the east of the "dead zone" is the boundary of the area where the earthquake occurred in 1999 with a magnitude of 7.4: Izmit earthquake with a total number of deaths of more than 17,000 people.

Scientists have found that this region may be a zone of accumulation of stress. This means that sooner or later the energy stored in the compressed rocks can come in the form of tremors: accurate predictions of the authors have not yet done, but find it necessary to pursue detailed studies of fracture fragment under the Sea of Marmara. The capital of Turkey, together with all the suburbs has 13 million inhabitants, it is one of the largest airports in the world and a lot of industries, so the researchers emphasize the importance of proper risk assessment.

A similar accumulation zone of seismic tension was in 2012 Found (Although at the time of Geophysics used other methods) in the Caucasus. However, and while scientists have not been able to give accurate forecasts, citing the need for further study of faults.
