This is a recently compiled standardized map of seismic hazard over Europe (Ukraine not yet included!). In older maps, the seismic hazards were defined differently in different countries, using different scales, making cross-border extrapolation uncertain. This model used harmonized data sets from all over Europe.
As you might expect, the deeper red colours represent the areas to be avoided (or at least the areas where you need to build to a high standard).
The map is a map of expected ground motion, which is dependent not only on the location and strength of probable earthquakes, but also local factors (ground condition being of critical importance). There is a lot more shaking experienced in soft sediment than on exposed bedrock.
The seismic hazard is an important consideration in building design.
