The subsidence of bays and river mouths on the Apennine Peninsula

Ludvík Loyda

Bays, lagoons, and river mouths were always hold for the most suitable places to set up harbours. Ancient landing places or harbours often had been subsiding under the sea surface, however. This is a proof of intensive sinking of blocks in such places. On the coast of the Apennine Peninsula rests of drowned towns and harbours over 2000 years old are being found. The relevellings have shown the sinking of the Po-delta, too. Drowned habours seem to verify the fact that minor blocks of the earth's crust on the bottom of bays and of river valleys sink more rapidly than their surroundings.
