Ankara's mayor Melih Gokcek warned that outside forces could be using sophisticated technology to try to trigger a manmade earthquake in a deliberate bid to harm Turkey's fragile economy.
His comments were made after two quakes hit the western Canakkale province on Monday and Tuesday morning, measuring 5.3 and 5.2 magnitude respectively.
Gokcek shared a video on his Twitter page, which claimed there were tools for causing manmade quakes, and he called all submarines and ships with large equipment to be taken under control of the authorities.
Gokcek said he had "researched" the two quakes and suggested they could have been caused by possible foreign interference.
"There was a ship conducting seismic research nearby. What this ship was researching and what country it belongs to must be solved," he wrote.
The ultimate aim, he suggested, was to trigger an earthquake near Istanbul in a bid to stage an economic "coup".
"At this moment, the coup aimed at Turkey is an earthquake near Istanbul to cause Turkey's economic collapse," AFP cited him as saying.
