I think #8 means something like "as soon as the earthquake is over, GET THE HELL OUT OF THERE AS FAST AS YOU CAN!!!!!!!!", thing that is a bit difficult if you are in the middle of the building.
BTW, the funny thing is that some times ago, our PE teacher told us what to do in case of earthquake/fire/gas leak/terrorist attack/Shivan invasion etc.
In case of earthquake, he told us to get under the desks or doorways and, as soon as it is over, run down the stairs

Actually, he also told us, in case of gas leak, to lay down on the floor because methane is lighter than air. But in case of a propane leak, we are all'doomed...
