When did we ever have flooding having water to the roof of houses...? At most its just a flooded basement and occasionally knee high on the ground level. The main highway leading into Copenhagen will get submerged pretty often though (maybe once or twice a year) though you can just drive around it with no extra time had it not been for the fewer amount of lanes.
Also iirc most hurricans will move westward so...
Also Denmark has the added feature of having the UK as a meat shield
As for earthquakes - ive never experienced one. Every time i hear about one happening it seems ive slept through it
I want to see a tornado...
