Library manager Shirley Lane said 5-year-olds who were in the library at the time of the drill took park by jumping under the tables.
Civil Defence Emergency Management director John Hamilton said he wanted the shakeout to be more than just a one-off, 10 second drill.
``Immediately after the drill is a good time for people to stop and talk about the drill, what they did, what might happen in a real earthquake, talk about their preparedness and also consider other emergencies,'' he said.
As of Monday, Wellington had the most people per-capita signed up for the event, with 33.8 per cent of the region's population signed up.
