On April 23, 2025, a 6.2 magnitude earthquake struck the Sea of Marmara, south of Istanbul, Turkey, at 12:59 pm local time.

The quake, which occurred at a depth of approximately seven kilometers and lasted 13 seconds, was followed by 51 aftershocks, the largest measuring 5.9 magnitude.

This seismic event has caused significant concern in Turkey’s largest city, prompting swift response from authorities and impacting residents.

According to Turkey’s Interior Minister Ali Yerlikaya, the initial quake was followed by 51 aftershocks recorded by 3:12 pm (1512 GMT). The largest aftershock, at 5.9 magnitude, added to the region’s instability.

The earthquake’s shallow depth amplified its impact, leading to widespread panic.

Over 6,000 emergency calls were reported, and 151 injuries were documented, primarily from people jumping from windows or balconies in fear.

The quake caused residents to evacuate buildings, with many choosing to remain on the streets, some planning to spend the night outdoors due to fears of further tremors.

No fatalities have been reported, but the psychological and logistical toll on the city is evident.

Interior Minister Yerlikaya stated that emergency teams were mobilized immediately after the quake.

Authorities have urged citizens to follow official statements to avoid misinformation and ensure public safety. The government’s rapid response included deploying all available resources to assess damage and provide assistance.

Multiple news outlets have reported on the event, emphasizing the scale of the aftershocks and the public’s reaction. BSS News, in collaboration with AFP, noted the earthquake’s proximity to Istanbul and the minister’s detailed update on aftershock activity.

TRT World and Khaleej Times echoed these reports, highlighting the government’s call for calm and adherence to official guidance. The Insider Paper and NST Online also covered the event, focusing on the seismic intensity and its immediate aftermath.

Istanbul, a city of over 15 million people, lies near the North Anatolian Fault, making it prone to significant seismic activity. The 1999 Izmit earthquake, which killed over 17,000 people, remains a stark reminder of the region’s vulnerability.

The recent quake has reignited fears of a potential “big one,” with experts warning that Istanbul is overdue for a major earthquake. The shallow depth and proximity to the city underscore the ongoing need for preparedness and infrastructure resilience.

The 6.2 magnitude earthquake and its 51 aftershocks have shaken Istanbul, causing injuries, widespread panic, and significant public concern.

While no deaths have been reported, the event highlights the city’s seismic risks and the importance of coordinated emergency response.

Authorities continue to monitor the situation, and residents are urged to stay vigilant. This incident serves as a critical reminder of the need for ongoing earthquake preparedness in one of the world’s most at-risk urban centers.
