- 7,000 kilometre(s)
The Book of World Records officially recognizes that The Andean Subduction Zone runs for some 7,000 km (4,340 miles) along the western coast of South America and is the longest destructive tectonic plate boundary in the world. Here, the denser ocean crust of the Antarctic and Nazca Plates is plunged below the lighter continental crust of South America where it is gradually recycled in the Earth’s upper mantle.
