Earthquakes and active faults
?
In short: Fault traces come from the GEM Global Active Faults Database (EMME compilation for the Middle East, SHARE for Europe) and earthquakes from the United States Geological Survey (USGS) catalogue. "Slip rate" is how far the two sides of a fault move relative to each other each year; the faster it is, the more often the fault produces earthquakes. For the official earthquake hazard see AFAD's Turkey Earthquake Hazard Map; for a parcel, a soil survey is essential.
