Ice bridge collapses at GROWING Argentina glacier – Video

Ice bridge collapses at GROWING Argentina glacier – Video

You might mistakenly assume the collapse came about because of global warming. That’s because articles about the collapse fail to mention that the glacier is growing. Yes, GROWING.

So how did ABC News handle it? They spun it this way:

“Experts said the collapse has nothing to do with climate change and was instead all to do with physics.”

Funny, isn’t it? The glacier is receding? Oh my God, it’s global warming! The glacier is advancing? Oh, that’s just “physics.”

Anyway, nature put on a stunning show for the 2,000 tourists and locals gathered at a catwalk to witness the collapse of the ice bridge at the Perito Moreno Glacier at 10.56 this morning.

The ice-bridge collapse is a regular occurrence, coming every three to four years according to National Parks Argentina.

Here’s how it works. As the Perito Moreno ice field advances toward the southern arm of Lake Argentina, it creates an ice dam.

As the water builds up behind the dam, it creates a tunnel through the glacier, thus forming the famous ice bridge.

The constant water flow of water through the tunnel gradually eats at the ice, leading to  spectacular ruptures.

The arch of ice that fell was 250 meters (820 ft) wide and 70 meters (229 ft) high –  the height of a 22-story building – and sent massive waves into Lake Argentina, spectators said.

With all stations in Argentina aiming their cameras at the glacier, the phenomenon was broadcast live to thousands of people watching on television.

Those lucky enough to witness the event in person clapped when the ice hit the water, making a striking thunder-like sound.

  1. Algeria, March 11, 2016. Tizi Ouzou: Several roads blocked by snow.
    Due to snowfall, several roads were closed to traffic yesterday in various localities of the province of Tizi Ouzou. The municipalities located in particular in high mounting are the most affected by the powder that closed the channels of communication.
    This is the case of the town of Ath Zikki (70 km southeast of Tizi Ouzou), on the edge of the wilaya of Bejaia, who found herself completely isolated in the space of a few hours, according to villagers. The situation is likely to last several days, as happened frequently in recent winters. Not far away, in Illoula Oumalou, snow has blocked roads to the villages where schools were closed all day.
    In the region of Ain El Hammam, road sections have also been blocked to traffic. Same story in the town of Iferhounène, where local officials have mobilized all the means available to the municipality to prevent the isolation of their village, drawing on the experience gained during the snowstorm of 2012, during which they have had to deal with an untenable situation.
    Also note that the road from Tizi Ouzou to Bouira, via Iboudraren is closed at Tizi n’Kouilal, like that which connects Illilten in Bejaia, blocked the pass of Chelata. The northern region of the province was not spared as the RN 72 connecting the city of Tigzirt in Tizi Ouzou has been hampered in the locality La Crête.

    This Algerian news website says that snow height was over 25 cm in several places. Ik could not copy and paste the text:

  2. Algeria, March 11, 2016:Weather: many roads cut off to traffic
    Tizi Ouzou: many roads cut off to traffic – Mohamed Haouichine Radio Chaine 3
    Rain, hail and snow were recorded in several provinces north of the country. This morning Setif woke up under a thick blanket of snow, says the radio correspondent Cahine 3. The thickness exceeded 25 cm in several localities.
    Traffic is extremely difficult on all urban roads, including major arteries, and silence singles outlying areas is disturbed only by the sound of engines snow removal equipment deployed at daybreak, a APS reported.
    According to information gathered from different regions of the wilaya of Setif, snow also affects the mountainous areas of the north, such as common Ain Roua and Bouandas and the south of the province where communities like Salah- Bey and Ain Oulmène are in a white coat.
    In Tizi Ouzou, many roads are cut off to traffic. The roads connecting the three wilayas (Bouira, Tizi Ouzou and Bejaia) are still inaccessible, says the journalist of Channel 3. Even snow plows mobilized to clear roads there are struggling to cope with snowfall continue to befall these communities.

  4. That was neat, no wonder they calve off alot, it looked like there were cracks way back in there, too much weight on top or a thaw & freeze and pop goes the iceberg.

  5. Moroccon news about neighbouring Algeria, March 11, 2016. SETIF – Significant snowfalls swoop down from the earliest hours of the day Friday on Setif and its region, does one found.

    Traffic is extremely difficult on all urban roads, including major arteries, and silence singles outlying areas is disturbed only by the sound of engines snow removal equipment deployed at the sunrise.

  6. That Ice Bridge collapses on a fairly regular basis It’s water trapped behind it as the Glacier flows out the bridge occurs through under cutting then. Doesn’t happen every year but fairly constant.

    Pressures from the weight of the ice slowly pushes the glacier over the southern arm (“Brazo Rico”) of Argentino Lake, damming the section and separating it from the rest of the lake. With no outlet, the water level on the “Brazo Rico” side of the lake can rise by as much as 30 meters above the level of the main body of Argentino Lake. Intermittently, the pressure produced by the height of the dammed water breaks through the ice barrier causing a spectacular rupture, sending a massive outpouring of water from the Brazo Rico section to the main body of Lake Argentina. As the water exits Brazo Rico, the scored shoreline is exposed, showing evidence of the height of the water build-up. This dam–ice-bridge–rupture cycle recurs naturally between once a year to less than once a decade.
    The last rupture occurred on March 10, 2016,[3] and previously, March 4, 2012, 2008, 2006, 2004, 1988, 1986, 1980, 1977, 1975, 1972, 1970, 1966, 1963, 1960, 1956, 1953, 1952, 1947, 1940, 1934 and 1917.[4] It ruptures, on average, about every four to five years.
    As of February 2012, before the March 2 rupture, the glacier dammed the Brazo Rico. The water level there had risen 5.6 meters.
