Read this chart carefully. Rising columns do not mean earthquakes are becoming more frequent. The monitoring network improved over time: the smallest detectable earthquake in Türkiye was about M5.0 in 1966 and is M1.5 today. Earlier years look quiet because small events were not heard, not because they did not happen.

Largest earthquakes

Inclusion rule: the radius widens with magnitude (15 km up to M4, 150 km at M7 and above). This is not a measure of felt shaking or intensity.

Method and sources

What this page counts
An earthquake appears here when its epicentre is within a magnitude-dependent distance of this place's border: 15 km up to M4, 30 km to M5, 60 km to M6, 100 km to M7, and 150 km at M7 and above. The rule exists because a large earthquake concerns neighbouring provinces too — the 17 August 1999 epicentre was in the Gulf of İzmit, on no province's land at all.
Location precision
Epicentre uncertainty is typically 1–10 km, and larger for older records. That is why this site breaks data down to districts but not to neighbourhoods or villages — the data does not support that distinction.
Magnitude scales
The catalogues use more than twelve magnitude scales (Mw, ML, mb, Md…) and they are not equivalent. Values are shown on the scale the source reported; they are not converted.
Deduplication
The same earthquake is published by several catalogues. Records within 20 seconds and 100 km whose magnitudes differ by no more than 1.2 are treated as one event; the primary record is chosen by catalogue priority.
Updates
Recent earthquakes are fetched from four sources every five minutes. The historical archive is rebuilt infrequently.
