Changing Safety Announcements

There has been an interesting progression in safety announcements here in the, getting less shakey, city.
After September (we identify our quakes simply by month) at the beginning of an event, the organiser would say in a jovial, chatty type way what to do if there was another aftershock. They would mention the word aftershock and they would just very quickly point to the exits and say where the meeting point was. There would usually be a bit of laughter from the audience and we would all assume, it would be unlikely. Then everyone would move on.
After February there was no more joking about aftershocks. The announcement was given completely seriously, the word aftershock or earthquake was used but then the explanation was pretty simple "you know what to do" and we all did.
After June, it has changed again. Now we appear not to like calling them by name. Now the announcer says something like "If we have one of those..." or "If something beginning with 'e' should happen.." but while the first part is now very downplayed what follows seems to be an extensive explanation of just where the exits are, sometimes repeating this and what to do once you have reached outside. This part is quite serious now. There are no titters from the audience, but a careful note of where the exits are - just in case. There is never any mention of fire, which is what I always remember such announcements being for.
Maybe in the new year, it will change again.
