Post traumatic stress disorder (PTSD) is something I’d always associated with military veterans and thus far removed from my life, but my response to the quakes has provided me an inkling as to the phenomenon. It is of course triggered by ground movement such as nearby construction that shakes the house. This morning, though, I noticed it could be triggered by mere sound: a vehicle producing sound in the same frequency as that preceding a large quake caused my arm hair to rise.
My response is subdued - I don’t panic, my pulse rate doesn’t rise, but I become instantly, intensely aware of my surroundings.
I’d like to hear similar stories from those who experienced the quakes. Please comment below. - William
