Chile is a long narrow country which extends like a ribbon down the west coast of South America. While the coastline is over 4,000 miles long, it is only about 61 miles wide. It is bounded on the north by Peru and Bolivia, on its long eastern border by Argentina, and on the west by the Pacific Ocean. Chile exercises sovereignty over Easter Island, the Juan Fernández Archipelago, and the volcanic islets of Sala y Gómez, San Félix, and San Ambrosio, all of which are located in the South Pacific. Chile is also a land of extreme natural events: volcanic eruptions, violent earthquakes, and tsunamis originating along major faults of the ocean floor periodically beset the country.
