Turkey's Active Fault Count Rises to 700 After Map Update

Turkey's map of active faults has been significantly updated, revealing an increase from 485 to 700 known active faults. The General Directorate of Mineral Research and Exploration (MTA) released the "Turkey Active Fault Map-2026," incorporating data and academic studies gathered over the past 13 years. This update is considered a crucial resource for seismic hazard analyses, critical infrastructure planning, and national disaster reduction policies.

The number of active faults in Turkey, previously identified as 485, has increased to 700 based on the work of MTA's geoscientists and geophysicists.

MTA General Manager Vedat Yanık highlighted that the update project, initiated in 2022, involved extensive fieldwork and academic research. He stated that the new map and its accompanying digital database will serve as a fundamental reference for understanding earthquake risks across the country.

“

According to the immutable law of earthquakes, if an earthquake of a certain magnitude has occurred in a place, an earthquake of at least that magnitude will occur there in the future.

Following the map's release, Professor Dr. Övgün Ahmet Ercan, a prominent seismologist, commented on the findings. Ercan praised the MTA's work, emphasizing a fundamental principle of seismology: "According to the immutable law of earthquakes, if an earthquake of a certain magnitude has occurred in a place, an earthquake of at least that magnitude will occur there in the future." He noted that the 700 identified faults have each produced earthquakes of magnitude 5.5 or greater.

“

Therefore, the work done is very important. I congratulate MTA for these valuable contributions.

Ercan congratulated the MTA for their valuable contribution, underscoring the importance of the updated fault map in assessing future seismic threats. The revised data provides a more comprehensive understanding of Turkey's geological activity and potential earthquake risks.
