Once a year, we have to practice earthquake drill - duck down, get under something solid, pretend it's shaking, hold on. For a minute. And then another minute, in case of aftershocks. Actually I skipped that last bit, because it wasn't in my instructions, and I only read about it in the LA Times (but of course that makes sense). This was the first time for me that it had actually coincided with a class - and as luck would have it, it was a class on "Photography and Trauma," so I could talk about photographs of earthquakes. It did, though, cause an odd interruption in the flow of affect, if not of logic - hard to go back from this to Isis chopping off heads, and Ebola sufferers.
