Oh yes. In Fairbanks we had shakers for a long time. And indeed a big truck would get everyone's heads popping up and looking for the nearest exit. We had a two story ceiling with one of those false ceilings with tiles and metal struts at the top. We had a few of those fall to the first floor (at work, a bank). The 36x24 tiles were bad enough, but the metal struts were no joke.
