Don't worry I can understand perfectly your question.
I have never been worried about earthquakes here. Telling the true I can only think of one or two times I could feel one earthquake a little, and just because I was living on a tenth floor. The feeling was very light and objects didn't move at all.
The last big earthquake in the peninsule was in 1755 and focused in Lisbon. There is a tectonic joint between the peninsule and Africa continent, but moving very slowly, 2 mm a year I read. It would require many centuries for a big earthquake like that one.
In Andalucia the activity when present is more felt on the eastern, like Granada, Almeria and east of Malaga. The earthquake origin was always very far from the coast into the sea.
My opinion is that we do not have to worry, I don't even think our children will have to worry...further than that, let them find out
I'm not a geologist, I can only say it's not something I care about.
