Avalanche triggered by Nepal quake was half as powerful as atomic bomb dropped on Hiroshima

The force of the avalanche that obliterated Langtang during the Nepal earthquake was so great that it was half as destructive as the atomic bomb dropped on Hiroshima during World War II, a reputed science journal has revealed.

A research article published by Science this week states that the massive avalanche of snow, mud and rock which was triggered by the 7.8 magnitude earthquake carried an energy equivalent to 7.6 kilotons of TNT while the Little Boy atomic bomb dropped on the Japanese city exploded with an energy of about 15 kilotons of TNT.

The article published in the renown science journal explains why most victims stood no chance during the Langtang avalanche. Given the remote location of the area, information about Mother Nature’s direct hit on the picturesque valley was slow to come out but when it did, it left the world in total shock because the village was completely buried by the avalanche.

The avalanche carried a powerful air blast too, in addition to the free-falling mass of rock and snow. It was this air blast that proved to be equally destructive. It was as powerful as a tornado with 200 miles per hour speed. “Air blasts leveled what was not buried in Langtang, including some buildings constructed of stone slab,” the highly academic report says.

Until it was hit by the tragic event of April 25, Langtang used to be a popular hiking destination both for local and international tourists. Thus, when the avalanche claimed the estimated 350 lives on the fateful day, many of the victims were from the west. Around 100 of the victims are still reported missing.
