The event started last fall. The Muldro Glacier, located in Alaska, began to move very fast last fall. Untouched for nearly 60 years, a pilot who flew over the site discovered that new cracks had opened up and that the ice cutters had been thrown into chaotic trouble, writes Washington Post.
Since then, the glacier has “moved” 100 times faster than normal.
– Imagine that you are driving through a school zone to work and that the speed limit is 50 kilometers per hour. Then, one day, you are driving your Honda Civic, suddenly the car is traveling at a speed of 5000 kilometers per hour, tells the psychologist Sam Herit to the newspaper.
Along with other researchers, Herit now began a race against nature to find the cause of the rapid movements.
According to the newspaper, the “waves” must be a mystery. Partly because it happens so rarely, in part it only happens in a few places around the world.
This activity occurs as the glacier size grows and it can take decades for the right conditions to develop.
The big difference
Typically, the Muldro glacier moves only 7.5 centimeters per year. Now the glacier is moving significantly. Measurements made by researchers now show that they move somewhere between nine and 18 centimeters daily.
A timelapse video shows how snow, rock, ice and earth are thrown forward like a giant draft. The researchers also have sound equipment to document the movements, but the ice acted as a natural backup and muted the sound of the ice eruption.
Scientists hope to see dramatic changes in the glacier by the end of June.

This may be due
According to Large Norwegian Encyclopedia Professional word for event Rise. It accumulates on top of the glacier as a result of extra large pressure from snow and ice.
Then the ice melts under the glacier, and the melting water acts like a lubricating oil, which helps the glacier gain speed.
