About Every 4 Years: Huge Perito Moreno Glacier Collapses in Argentina

Argentina’s massive Perito Moreno glacier collapses in front of thousands of people gathered to view the event in Los Glaciares National Park.

The Perito Moreno glacier is located 48 miles from El Calafate, located in the Los Glaciares National Park in southwest Santa Cruz Province, Argentina. A dam–ice-bridge–rupture cycle recurs naturally between once a year to less than once a decade.

Pressures from the weight of the ice slowly pushes the glacier over the southern arm (“Brazo Rico”) of Argentino Lake. Ice damming results. With no outlet, the water level on the “Brazo Rico” side of the lake rises by as much as 30 meters above the level of the main body of Argentino Lake. Every 2 to 4 to up to 10 years, the pressure produced by the height and depth of the dammed water breaks through the ice barrier. A spectacular rupture and collapse of ice sends a massive outpouring of water from the Brazo Rico section to the main body of Lake Argentina.
