Here's an argument to beef up seismic capacity anywhere in the world. As we know from Italy and Texas, an M6 can happen almost anywhere at any time. For this type of earthquake, we can expect a ground motion (PGV) of 20 cm/s. You need medium robustness to hold out here. You look at these cheese racks and they were ready to bust on their own, without an earthquake.
And here's an interesting article from the Clueless Swiss. They are beefing things up, but I hate that idea of cutting out columns and putting in bearings.
Can't wait to see how that pans out!
