Japan has the strongest earthquake codes in the world, but there are still lots of older buildings and they got a big shock in 1995 in the Kobe quake from all the destruction; they had gotten a bit smug and overconfident about their codes and preparation, and then got socked with 5,000 killed and 200 billion dollars in damage.
5,000 I never knew it was that devastating.
I know nothing about locations but hoping these are hitting in a non populated/big city area.
