The Changing Coastlines of South America

South American coasts are subject to many different natural hazards. In general terms, the Pacific coast is tectonic, and therefore, earthquakes and tsunamis are likely to occur in this area. The Caribbean coast is constantly subject to trade winds and episodically to hurricanes and tsunami-triggere...
