Considered one of the most impressive natural spectacles in the world, the collapse of the ice masses occurred around 22h48 local.
The natural collapse of the bridge that the Perito Moreno glacier forms on the peninsula of Magallanes, in the southern province of Santa Cruz, in southern Argentina, happened on Sunday night and without the public.
Considered one of the most shocking natural spectacles in the world, the collapse of the ice masses that form the most picturesque part of the glacier, located in the Los Glaciares National Park, occurred at around 10:48 pm (same time in Brasilia).
This process, which began on Saturday and did not occur since March 2016, always attracts hundreds of tourists, although this time the collapse occurred without a public due to the special security operation that closed the site overnight.
The phenomenon of rupture, natural and recurrent, is caused by the pressure that the waters of Lake Argentino exert on a natural dam that Perito Moreno, known as the ” white giant “, is conforming in its slow advance on the rocky coast.
These pressures form an arc, which ends up falling, causing a break of imposing characteristics.
On Saturday, the Intendencia responsible for the park warned that a leak was occurring “more and more evident and mighty, by which we are in a position to affirm that the process of rupture of the Perito Moreno glacier began .”
It is customary for the phenomenon to occur at this time of year, at the end of the austral summer, although in some occasions it occurred in July, in the middle of winter.
Perito Moreno, with an extension of about 200 square kilometers, is situated on the Andes Mountains and is one of the few in the world that remains stable, without retreating as a consequence of global warming.
The glacier is 60 meters high, like a 20-story building; has a front of 5 kilometers and its surface is approximately the one of the City of Buenos Aires.
Its name honors to Francisco Moreno (1852-1919), explorer of the zone and director of the museum of the Scientific Society of this country.
