would probably be more relevant if it only showed events above a certain threshold of strength. Europe looks all black but is now (most of it anyway) a hotspot of seismic activity.

It presumably does, but the threshold is unreasonably low. I can't find any information about what the map actually represents, but here's one color coded for strength (though scanned with a resolution that makes the scale unreadable). Most of Europe looks much better now.

to be truly accurate, in terms of danger, would be to superimpose a map of seismic building codes.  A 5.2 in most of Germany (a sneeze in Frisco) would have some damage, and a 5.8 would begin to be significant.  But the real issue in this discussion is the time scale, thousands of years.

You also need to know something about enforcement of these codes. With L'Aquila in mind, I assumed that Messina would have very strong building codes, but that enforcement of them would be lax. But maybe not: it turns out that in the 1975 earthquake in Messina (strength 5.4)
The most significant of these earthquakes was the January 16, 1975 event, measuring M5.4 and causing heavy damage to just three buildings in Messina.
Maybe two 7.5 earthquakes really does focus peoples minds, even in Southern Italy.
