The Breakthrough Theory That Could Dispel Fear of the Islands Fault

Breaking: Marmara’s Major Faults Deemed Inactive, Major Istanbul Quake Unlikely – Expert Says

Renowned seismologist prof. Dr. Şener Üşümezsoy discussed potential quake scenarios for the Marmara region during a live interview on Sözcü TV.

He emphasized that the Adalar Fault lacks the stress build‑up required to generate a significant seismic event.

Key Faults and Their Current Status

Fault Segment	Maximum Potential Magnitude	Stress Accumulation	Recent Activity
Yalova‑Çınarcık‑Esenköy line	6.5	None – energy released in 1894	Stable
Silivri‑Büyükçekmece segment	Up to 6.5	Depleted – ruptured in recent years	Considered “dead”
Büyükçekmece‑Avcılar‑Yeşilköy extension	6.0‑6.5	No active stress	Classified as inactive

According to Üşümezsoy, the yalova‑Çınarcık‑Esenköy corridor can theoretically produce magnitude‑6.5 tremors, yet the 1894 event discharged the stored energy, leaving the line stress‑free.

“That Is a Dead Fault” – What It Means for Istanbul

The most concerning structure in Marmara was the active Silivri‑Büyükçekmece fault. however, recent ruptures have tired its potential, rendering it incapable of a repeat event.

With no remaining segments showing dangerous stress levels,the prospect of a major earthquake striking Istanbul or the broader Marmara basin is considered unrealistic.

Did You No? Historical seismic releases, such as the 1894 Marmara quake, can permanently lower the strain on surrounding faults, reducing future hazard potential.

Pro tip: Residents should still follow standard earthquake preparedness measures-secure heavy furniture, maintain emergency kits, and stay informed via official seismology agencies.

Evergreen Insights

Understanding fault mechanics helps communities gauge long‑term risk. While a “dead” fault cannot generate a large quake, micro‑seismic activity may still occur. Continuous monitoring by institutions such as Kandilli Observatory ensures any subtle changes are detected early.

urban planners worldwide use similar fault assessments to inform building codes, zoning, and infrastructure resilience strategies.
