Sad.
I have been to Lorca a couple of times. It is a small city south of Murcia (a big regional city in the Comunidad (or “state” of Murcia). It is very traditional but very modern at the same time and I liked it a lot.
In terms of residences, Spain has everything ranging from caves to traditional adobe or stone buildings to modern brick buildings. And none of them are earthquake resistant because earthquakes simply aren’t that common on the Iberian Peninsula. But when they hit, it can be pretty bad...do some research on the Lisbon earthquake.
Prayers for these people, because it was something unthought of, completely outside of their experience, and unintelligible to most modern de-Christianized Spaniards.
