Türkiye has been rattled by a series of earthquakes over the past 41 hours, the most powerful being a 6.2-magnitude tremor, according to foreign media and seismological agencies.

The initial earthquake struck on Wednesday at a shallow depth of 10 kilometres, the German Research Centre for Geosciences (GFZ) reported. It was followed by several aftershocks, including a 4.9-magnitude quake in the Sea of Marmara and a 5.3-magnitude quake recorded in Istanbul.

According to the Turkish Disaster and Emergency Management Authority (AFAD), the epicentre of the major quake was near the Silivri district of Istanbul province, at a depth of 12 kilometres. No tsunami threat has been issued, and authorities said emergency assessments are underway to evaluate the extent of any damage.

The tremors were felt as far as Greece, Italy, Portugal, and France, prompting regional alerts. This marks the seventh recorded earthquake in Türkiye in less than two days, highlighting heightened seismic activity in the region.

So far, no casualties have been reported. However, the authorities remain on high alert as aftershocks continue to be felt in several provinces.

Türkiye, located on major fault lines, is prone to frequent seismic disturbances. The latest quakes have reignited concerns about preparedness and infrastructure resilience in urban areas like Istanbul.

Emergency teams are on standby, and the government has urged residents to stay cautious and follow official advisories.
