Three large lakes — Lake Ohrid, Lake Prespa and Dojran Lake — lie on the southern borders of the Republic, bisected by the frontiers with Albania and Greece. Ohrid is considered to be one of the oldest lakes and biotopes in the world
The region is seismically active and has been the site of destructive earthquakes in the past, most recently in 1963 when Skopje was heavily damaged by a major earthquake, killing over 1,000.
