A spectacular thunderclap in Patagonia

... But no tourists heard it! 

The arch of the gigantic Argentinian glacier, Perito Moreno, broke in the night of Sunday to Monday, March 12th.

The thousands of tourists who had gone there to witness the impressive collapse of huge blocks of pure blue ice that produced a sound like a thunderclap could not attend because the Los National Park Glaciares in Patagonia, located 2,000 km southwest of Buenos Aires, was closed when the spectacular phenomenon occurred.

There will be another time ... 

The collapse of Perito Moreno, a UNESCO World Heritage Site, usually occurs in March; that is, in the late summer and early autumn.

This phenomenon, one of the most impressive natural shows in the world, has been happening every two to four years since 2004, when it had not happened at all in the previous 16 years. The last time, in 2016, was in broad daylight and thousands of tourists attended. So unfortunately, or luckily for the tourists, all is not lost!

According to Luciano Bernacchi, director of the Glaciarium, a museum located near the Glacier National Park, this is a natural phenomenon for this type of glacier. The singularity of the latter is due to the fact that it progresses continuously, unlike other glaciers, which lose their frozen surfaces.

The front of the glacier is more than 60 meters above the water at its maximum height. Different sized pieces constantly fall from it.
