Belgrade is not on seismic active area, and it's very unlikely that we will be hit by devastating quake.
But, some areas around Belgrade, including some parts of central Serbia, Romania etc are...
Strongest quakes we felt were those in area i mentioned...Skopje, Bucharest...etc....
One of the strongest quakes we were hit by is Skopje quake in 1963 (
http://en.wikipedia.org/wiki/1963_Skopje_earthquake ). After that one huge improvements in construction were introduced ( like that one i mentioned ).
Interesting thing...only building oriented in specific way felt that quake really hard ( like mine

)....others, that were oriented different way felt only small tremors...
Anyway...even i do know that quake most probably wont kill me, i'm scared do death when building starts to shake...
It's one of those feelings when you can't do absolutely anything to help yourself....
