An earthquake of mag. 4.5 at a depth of 10.7 km. has occurred today at 14:44:32 local time. Just about half an hour ago. The location is after the Boshorus ends and you go into the Black Sea. One geologist said it could be a collapse of the sea floor. It was felt in Istanbul. Istanbul is waiting for an earthquake in the Marmara Sea and now the Black Sea. I guess we will be sandwiched in between.
