Istanbul, Turkey—April 23, 2025— Two earthquakes were recorded in the Marmara Sea near Istanbul on Tuesday, sparking alarm among residents and prompting official reassurances. Though no injuries or major structural damages were reported, the incident reignited public discourse on Turkey’s seismic risks.
Earthquake Details
According to Turkey’s Disaster and Emergency Management Authority (AFAD), the first earthquake measured 4.0 on the Richter scale, closely followed by a second quake measuring 3.9. Both occurred in the Marmara Sea region and were felt strongly across Istanbul and surrounding areas.
- First quake: Magnitude 4.0
- Second quake: Magnitude 3.9
- Depth: Approx. 7 kilometers
- Location: Offshore Marmara Sea, south of Istanbul
Public Reaction and Safety Measures
In response to the tremors, many residents in Istanbul temporarily evacuated buildings and sought updates from emergency services. Authorities confirmed that no critical infrastructure had been affected and urged the public to remain cautious but calm.
The Istanbul Governor’s Office issued a statement reassuring citizens that emergency protocols were being followed and teams were monitoring for potential aftershocks.
A Seismic Reminder for Istanbul
Seismologists have long warned of a possible major Istanbul earthquake due to the city’s proximity to the North Anatolian Fault Line, one of the most active and dangerous fault systems in the world.
Dr. Emre Karakaş, a leading geophysicist, commented:
“These tremors are part of an ongoing tectonic process. While today’s earthquakes were not destructive, they should not be ignored. Istanbul must remain vigilant and continue investing in earthquake preparedness.”
The Bigger Picture: Earthquake Preparedness in Turkey
Turkey is one of the most earthquake-prone countries in the world. The memory of the 1999 İzmit earthquake, which killed over 17,000 people, still looms large, especially in urban centers like Istanbul.
Residents are encouraged to:
- Keep emergency kits on hand
- Learn safe spots within their homes or workplaces
- Participate in local earthquake drills
- Stay informed through official channels like AFAD
