I'm still alive!! All is well in Fujian. Never felt a thing. I never knew there was such a serious earthquake until I turned on my computer and saw the news. Shocking. Earthquakes sometimes also hit Fujian, but I never notice or feel anything.
Building construction in China is kind of shoddy. They use very soft clay bricks which they then coat over with cement to give a smooth surface. They do use rebar when they pour concrete - but maybe not enough. Buildings look good on the outside, and may have a nicely finished interior. But within the walls... not good. So it's not surprising so many buildings collapsed. I would feel safer in a mud- brick and wood/bamboo post house like the kind people still use in the countryside.
