It's...odd: these 6.something quakes happen essentially at most 1-2 times a decade. 8+ like in Japan are extremely rare.
This means that in some places things get reinforced/restructured accordingly, but historic city centers with many seriously old buildings remain vulnerable, since it would be technically possible but expensive to reinforce them, as done in Norcia, which almost didn't have any damage.
It must be noted however that new buildings must follow regulations to make them more or less quake-proof, but in part they might not be followed due to corruption/inertia, and provided they are followed obviously no news program will go and tell "here nothing happened", if you get my point.
