Risk Matrix

X: Seismicity rate (relative) · Y: Years since last major earthquake · Size: Dominant band risk score

04Geological Context

Eren Bostan·[TAL-704]document tectonic regime groupings

Tectonic Context

Subduction Zone

Tokyo · Santiago · Jakarta

These regions, where oceanic crust dives beneath continental plates, produce the largest earthquakes on record. Stress accumulated over hundreds of years along the subduction zone is released in periodic megathrust ruptures. Tsunami hazard is high.

Strike-Slip

Istanbul · Maraş · Yedisu · San Francisco

In these systems where plates slide past each other, stress builds at a linear rate. Faults like the NAF and San Andreas can remain quiet for decades while preparing an M7+ earthquake; urban proximity multiplies damage risk.

Extensional / Graben

Izmir · Athens · Iran

Normal faults formed by crustal extension are widespread across the Aegean and the Iranian plateau. Shallow focal depths amplify local damage. The Zagros fold-and-thrust belt and the Corinth rift system are typical examples of this category.
