Speaking for Romania here (if you go more "Central" they have smaller earthquakes and it might be different), the houses are supported by pretty big reinforced concrete columns, and the floors/ceilings are all reinforced concrete. You can use other materials other than brick, like aerated concrete bricks, the main role is thermal/sound/fire insulation, there is no strength value assigned to the walls, only to the corners+columns. e.g. https://img3.imonet.ro/XV08/V0801LH4N7O/casa-la-rosu-in-oras...
Romania used to have brick-only houses, but after a major earthquake in 1977 that is not allowed anymore.
Bricklaying is relatively easy, and it's a quick part of the building process, it only takes a couple of days for a regular house. I was looking at the robot, and an experienced bricklayer can lay the bricks just as fast, if you can keep the bricks and mortar coming.
