• Did you know that when renting or buying a house or evaluating the location of the building you currently live in, you can examine the live map prepared by the official geoscience engineers of the state with your own eyes, instead of worrying by looking at the blurry and unsourced "fault line" pictures circulating on social media? There are two official reference sources in Türkiye that show the updated active fault data and the earthquake hazard acceleration of the ground, street by street: MTA Geoscience Map Viewer and AFAD Türkiye Earthquake Hazard Maps (TDTH).

  MTA Geosciences Portal on the map of Türkiye without the need for any password Living Faults (Holocene fault, Quaternary fault and lines that may form surface fractures), Landslide areas and Geological formations opens layer by layer and allows you to get closer to your own district/neighbourhood. If at the engineering level that point Ground Acceleration (PGA) value and get the official report, you can see the AFAD TDTH (tdth.afad.gov.tr) system via e-Government and clicking on the coordinates where your building is located.

• STEP BY STEP USE:

  1. From your browser https://yerbilimleri.mta.gov.tr/anasayfa.aspx (No membership or password required).

  2. The "Layers"from the menu"Active Faults" box (If you want, check the "Landslide" or "Geology" layers).

  3. Zoom in directly to your city, town, and neighborhood using the search/location tools in the top right or by rolling your mouse wheel on the map.

  4. "Legend (Description)" tab to examine which type of fault line the red, purple and orange lines you see on the map represent.

  5. To get official point-based ground motion/acceleration report https://tdth.afad.gov.tr/, "Login with e-Government" button and click on the point where your house is on the map "Get Report" command.

• REQUIREMENTS AND LIMITS: MTA Geosciences map is non-subscription; AFAD TDTH requires e-Government verification. Very Important Scientific Frontier: These maps determine whether a building is stable or likely to collapse does not show (building durability depends on concrete quality, reinforcement and soil survey and performance analysis). Maps only show the proximity of the selected geographical location to fault lines and the expected ground motion hazard.

• PRIVACY AND SECURITY: T.R. They are 100% official public systems operated by the Ministry of Energy and Natural Resources (MTA) and the Ministry of Internal Affairs (AFAD). Instead of entering your personal information or location into third-party fake "earthquake query" sites, just these two .gov.tr.

• ADVANTAGES, DISADVANTAGES AND WHOM IT IS SUITABLE FOR:

  • Advantages: The most up-to-date official MTA active fault and landslide layers, AFAD point-based ground acceleration report, completely free and ad-free, offering scientific data instead of rumors.

  • Disadvantages: MTA map may hold for a few seconds while loading during peak hours; To understand the geological terms on the map, it is necessary to look at the "Legend" explanation in the left menu.

  • Who is it suitable for: Citizens who will buy or rent a house, civil/geology/geophysics engineers, students and anyone who wants to gain disaster awareness.

• BRIEF CONCLUSION: You can find out the geological structure of the area where you live or plan to move and its distance to active faults directly, not through hearsay yerbilimleri.mta.gov.tron"Active Faults" layer!
