An earthquake with a magnitude of 6.2 hit the Marmara Sea near the western outskirts of Istanbul on Wednesday (April 23, 2025), officials said, with the impact felt across Turkiye’s largest city where people rushed onto the streets.

“An earthquake of 6.2 magnitude occurred in Silivri, Marmara Sea, Istanbul,” Interior Minister Ali Yerlikaya said on X, adding that it was felt in the surrounding provinces.

The initial quake at 12:49 p.m. (0949 GMT) was followed by three others of with magnitudes of 4.4 to 4.9, Turkiye’s AFAD disaster management agency posted on X.

As buildings shook, people rushed onto the streets where crowds of worried-looking people stared at their mobile phones for information or made calls, an AFP correspondent said.

“I just felt earthquake, I’ve got to get out,” said a shaken-looking decorator rushing out of a fourth floor apartment where he was working near the city’s Galata Tower, who did not want to give his name.

There were no immediate reports of anyone being hurt or killed nor of buildings collapsing in the sprawling city of 16 million people, city authorities and the regional governor’s office said.

“Until now, we have no information about any buildings collapsing,” the governor’s office said, urging people to avoid any structures that might have been damaged in the tremors.

“No serious cases have been reported so far following the earthquake in Istanbul,” the Istanbul municipality said on X.

The tremors could be felt as far away as Bulgaria, according to AFP journalists in the capital Sofia.

51 aftershocks follow

More than 50 aftershocks rocked the Istanbul region after the earthquake Mr. Yerlikaya said.

“By 3:12 pm (1512 GMT), 51 aftershocks — the largest of which was 5.9 magnitude — had been recorded,” he wrote on X, saying the first 6.2 magnitude quake, which hit at 12:59 pm was “approximately seven kilometres deep lasted a total of 13 seconds”.
