Istanbul residents spend night outdoors after quake

Many Istanbul residents spent the night outdoors, too fearful to return to their homes, following a strong earthquake and more than 180 aftershocks.

The magnitude 6.2 quake tremor that struck on Wednesday deeply impacted the city of 16 million residents, leaving many inhabitants shaken and wary of a possible more destructive tremor.

There were no reports of serious damage, but the earthquake, the strongest felt in Istanbul in recent years, prompted widespread panic and scores of injuries.

The earthquake had a shallow depth of 10km, according to the United States Geological Survey, with its epicentre 40km southwest of Istanbul, in the Sea of Marmara.

It was felt in several neighbouring provinces.

At least 236 people were treated for injuries they suffered while trying to jump from buildings or for panic attacks.

Most of the injuries were in Istanbul, where residents remain on edge because the city is considered at high risk for a major quake.

In fear of a stronger earthquake that could demolish homes, residents sought refuge by sleeping in their cars or setting up tents in parks and other open spaces.

Many lit campfires to keep warm after the temperature dipped.

Turkey is crossed by two major fault lines, and earthquakes are frequent.

For many, the memory of a devastating earthquake that struck 11 southern and southeastern provinces two years ago remains vivid.

The 7.8-magnitude earthquake on February 6 2023, claimed more than 53,000 lives and destroyed or damaged hundreds of thousands of buildings.

Another 6,000 people were killed in the northern parts of neighbouring Syria.

The Turkish disaster and emergency management agency, AFAD, said Wednesday's earthquake was followed by 184 aftershocks - seven of them of a magnitude four or stronger.

Environment, urbanisation and climate change minister Murat Kurum stated that authorities had received 378 reports of structural damage in various buildings.

At least 12 buildings had been evacuated as a precautionary measure, he said.

Only one building - a derelict, long-abandoned structure in the city's historic Fatih district - collapsed.

Germany's GFZ seismological research institute said the earthquake was the strongest in the area in more than 25 years and extended the fault zone towards Istanbul.
