By 7 pm aftershocks were more than 120 size up to 4.9 Richter.
“Bell” Turkish professor of geology: “The real earthquake will be over 7 Richter”
“The real earthquake will be bigger,” he had warned last December The Turkish Professor of Geology, Dr. Naci görürafter a 4.4 -degree vibration in the same area as it gave 6.2 Richter.
Specifically, he warned that the 4.4 R that had then occurred would affect Marmara’s rift, probably causing a major earthquake in the future. “This earthquake will pretty much affect the section of the rift that is expected to break in Marmara“, He had said.
Indeed, this professor had also warned last summer of a strong earthquake expected in Constantinople and other parts of Turkey.
So after the vibration barrel in Constantinople the Dr. Naci Seres He came back, saying: “The Kumburgaz rift in the Marmara Sea in Constantinople has many earthquakes. They are different sizes. These are not the big earthquakes we expect in Marmara. Increase the pressure that accumulates in this rift. In other words, they force it to break. The real earthquake here will be larger and over 7».


Papazachos: Can Greece be more powerful in Turkey – Can Greece be affected?
At the same time, the AUTH seismology professor appeared reassuring, Costas Papazachos for the possibility of influenced Greece by the earthquake barrel in Turkey.
“It’s a typical earthquake, strong but not very worrying,” Mr Papazachos said, speaking to ERT.
But he stressed: “The only evil with this particular earthquake is the fact that it is on a very rich zone, which gives very large earthquakes. Historically it has given earthquakes over 7 Richter with many victims and very big damage.
Costas Papazachos says that everything is possible and within the next few hours or days to become a much larger earthquake:
“An earthquake of 6 Richter can not tell you anything on its own, because this zone itself has a very great momentum. Residents of these areas will be difficult, because they will have earthquakes next time. It will take some time to make sure that it is the main earthquake. “
Karastathis: “In no case was the size of the estimates. Was finally smaller »
“This is an area with a very large potential that has been a strong earthquake for many years,” said the Vassilis Karastathis, Director of the Geodynamic Institute of the Athens Observatoryadding that the easternmost part of this zone has repeatedly broken. He explained that “the last earthquake that occurred there was in 1999 in Nicomedia.
There is a piece of the rift that is still aslest and which reaches the bay of Saros, where On August 9, 1912 we had a strong earthquake, 7.2 Richter” According to Mr Karastathi, many seismologists from all over the world were expecting an earthquake in the area, but today’s size, “was by no means analogous to estimates. It was finally smaller. “
Concerning the evolution of the phenomenon, Mr Karastathis estimated that “We are at an early stage. Because the potential of the area is as we said too big, we must be cautious».
From his own point of view, the president of OASP, Efthymihe said that the phenomenon is remarkable and is considering whether it is the main earthquake or intent. “It is a phenomenon that concerns us, especially because of the focus of the focus,” he said.
On his part, the Akis ZelentisHe warned by posting on Facebook about the high seismic danger of the area, noting that “the king needs special attention”, and noted that the possibility of affecting the northern Aegean rift is small but not zero.


The 6.2 Richter Chronicle in Istanbul
“A earthquake of 6.2 degrees It was noted in Silibria, in the Marmara Sea, in Constantinople, “the interior minister had said in the morning, Ali Erlikaya In x, adding that it was felt in the surrounding provinces.
