Official Source Revalidation — Earthquake risk screening
Primary official evidence
AFAD’s current hazard map took effect on 1 January 2019 and is a hazard map, not a building-risk certificate; it uses point-based ground-acceleration values rather than the old earthquake-zone grades. Revalidate site hazard through AFAD and official risky-building status/process through the Ministry. Under Law 6306, official risky-building determinations follow defined technical rules and authorized bodies; marketing opinions do not replace that process. AFAD explicitly says it is a hazard map, not a building-risk map; the interactive map also excludes local-site effects such as liquefaction, amplification and differential settlement. Return to the competent public authority or official system and verify the current record; a secondary summary is not a substitute for the controlling source.
Key verification points
AFAD explicitly states that the national earthquake hazard map is not a building risk map, so a map colour cannot be converted into a structural-safety conclusion for a specific property.

Document and identity reconciliation
earthquake risk screening: AFAD explicitly states that Türkiye’s Earthquake Hazard Map is a HAZARD map, not a building RISK map; assessing a specific building requires exposure/structural information and local conditions in addition to regional hazard. AFAD’s current hazard map was published on 18 March 2018 and entered into force on 1 January 2019. earthquake risk screening: AFAD explicitly states that Türkiye’s Earthquake Hazard Map is a HAZARD map, not a building RISK map; assessing a specific building requires exposure/structural information and local conditions in addition to regional hazard.
Timing and change risk
For Official Source Revalidation — Earthquake risk screening, log every mismatch or missing item as a separate exception: the field involved, the conflicting document, the authority responsible for correction and the condition that blocks closing until resolution. AFAD explicitly states that the national earthquake hazard map is not a building risk map, so a map colour cannot be converted into a structural-safety conclusion for a specific property. The Ministry states that risky-building determinations follow prescribed technical principles and are made through authorized bodies under the 6306 framework. Where structural concern exists, separate geographic screening from the formal Riskli Yapı process.
Decision standard
For Official Source Revalidation — Earthquake risk screening, if registry, project, numbering or share data changes after verification begins, preserve the old and new versions with date and reason. A valid change may be legitimate; relying on a superseded version is the real risk. Earthquake screening should begin with site hazard but must not end there. AFAD explicitly states that the national earthquake hazard map is not a building risk map, so a map colour cannot be converted into a structural-safety conclusion for a specific property. Where structural concern exists, separate geographic screening from the formal Riskli Yapı process. The Ministry states that risky-building determinations follow prescribed technical principles and are made through authorized bodies under the 6306 framework.
For Official Source Revalidation — Earthquake risk screening, What official evidence should control this check?
For Official Source Revalidation — Earthquake risk screening, preserve a file that can be handed to the next buyer: reference record, verification results, corrections, supporting documents and last-check date. A strong file shortens future due diligence and avoids rebuilding the property history from scratch. Earthquake screening should begin with site hazard but must not end there.
