According to NASA, a huge volcanic eruption in the atmosphere of the Earth exploded in December.
The explosion was the second largest in 30 years and six years ago it was the largest after the volcano on Chelyabinsk in Russia.
But until now it has become strangely because it got over the Bay of Wind outside Kamchatka peninsula of Russia.
The power released by Hiroshima nuclear bomb is 10 times higher.

A NASA-based Asteroid Defense Officer Landley Johnson told BBC News, this large firearm is expected almost every two or three times in every 100 years.
On December 18, at a local time, asteroids surrounded at a speed of 32 kilometers at 7 degrees Celsius through the atmosphere.
Measuring several meters in size, the space rock exploded 25.6km above the Earth's surface, with an impact strength of 173 kilotonnes.
"40% Chelyabinsk was released, but it was on the Bay of the Sea so it did not have the same effect or was not seen in the news", Casey Fast said, NASA's Earth Object Monitoring Program Manager
"It's another matter in our defense, the planet has plenty of water."
Military satellites sort out blast last year; This incident was initiated by the US Air Force.
John Johnson said firearms came in an area not far away from the routes used by flying commercial flights between North America and Asia. So researchers are examining whether to check this event with the airlines.
In 2005, Congress made NASA responsible for 90% of the planet near 140 meters in size or 90% of planets in 2020. These size space rocks are called "problems without passports" because they are expected to affect entire regions, but scientists estimate that it will take another 30 years to fulfill the congressional order.
Once an incoming object is detected, NASA is based on a certain firmity in its orbital, where the effect would have been some significant success.
In June of 2016, 3 hours of asteroids from the land-based observation center in Arizona were discovered eight hours before the AH asteroid discovered in 2018. The NASA's Jet Propulsion Laboratory (JPL) determines the accuracy of its orbit, which is used to calculate potential impact position. This rock showed the potential to hit South Africa.
According to the calculation, a firearm was recorded in Botswana by a farm security camera footage. The fragments of the object are available in the area later.
