Noise and noise around Mount Everest..and scientists reveal the reason

Weather of Arabia - As soon as the sun sets on the Himalayas and temperatures drop, noises and noises emerge from the depths of the glaciers around Mount Everest, which baffled scientists and prompted them to search for the secret of what is happening.

The researchers, led by scientist Yevgeny Podolsky, found that the crashing and spalling of glaciers is caused by the sharp drop in temperature that causes ice to break up after dark.

Podolski and his team spent three weeks near the source of the sounds on Mount Everest, confirming that the cause was ice breaking due to very low temperatures after sunset.

"It was a cool experience," said Podolsky, who works at the Arctic Research Center at Hokkaido University in Japan. "During the day we worked in T-shirts, but by nightfall the temperature could drop to around -15 degrees Celsius."

He added, "After dark, we heard a loud explosion and we noticed that the glacier was exploding."

The team placed sensors on the ice to measure vibrations deep in the glacier, the same technique used to measure the magnitude of earthquakes.

The researchers collected seismic data on vibrations and compared them with temperature and wind data, helping to establish a strong relationship between temperature fluctuations and nocturnal noise.

The research could help more teams of climate experts better understand the behavior of glaciers in remote regions such as deep in the Himalayas, which are home to one of the largest stores of ice on Earth.
