 In the Middle Adriatic Basin, there is evidence of Permian volcanism in the area of Komiža on the island of Vis, in addition to the volcanic islands of Jabuka and Brusnik.Earthquakes are frequent in the area around the Adriatic Sea, although most are too faint to be felt; an earthquake doing significant damage happens every few decades, with major earthquakes every few centuries.The Dinaric Alps are linked to a Late Jurassic to recent times fold and thrust belt, itself part of the Alpine orogeny, extending southeast from the southern Alps.
