In October 1961, a Soviet Tu-95 bomber dropped the toughest thermonuclear bomb in history on the remote island of Novaya Zemlya, north of the Arctic Circle.In 1950, Russia operated with a hundred-megaton hydrogen bomb, but with technical limitations (the planned bomb was too heavy and too big to be lifted on an aircraft) and concern about widespread nuclear pollution convinced the government to settle for a smaller version., weighing only 26.5 tonnes. Despite its small size, the bomb passed through the gates of the flight’s bomb bay.
The 50-megaton bomb, dubbed “Great Ivan” by the Russian imperial czar known as Ivan the Terrible, exploded at an altitude of 13,779 feet. Castillo Bravo, the toughest nuclear weapon ever tested in the United States, brought in just 15 megatons. and “Ivan” 3,800 times harder than the atomic bomb dropped on Hiroshima in 1945.
The bomb’s fireball was between 8 and 10 km (5.0 to 6.5 miles) wide at its maximum; the mushroom cloud was more than 90 km (59 miles) wide, enough to cover the island of Manhattan twice; onlookers saw a soft flash from more than 965 km (600 miles) away and felt its heat within 250 km (160 miles) of Ground Zero. The shock wave would have shattered windows more than 490 miles away. The crown of the mushroom climbed more than 65 km (213,000 ft) high, just below the edge of space.
Last week, Rosatom State Atomic Energy Corporation (Russian state atomic agency) posted 40 minutes of past classified images, showing the bomb’s trail to the remote control site and the resulting explosion, on the online video-sharing platform. Youtube. The opening title says “Top Secret”.
In 1963, the United States, the Union of Soviet Socialist Republics (USSR) and the United Kingdom signed the Treaty on the Limited Prohibition of Nuclear Tests, which prohibited the use of airborne nuclear weapons.Since then, atomic trials have continued underground, the last in North Korea in 2018.
While the detonation of a nuclear device and the extraction of uranium and other fissile curtains release giant amounts of radioactive dust into Earth’s atmosphere, some geologists recommend using the appearance of radioactive rain in Earth’s geological archives as a marker of the anthropoccene, a proposed geological era that reflects humanity’s profound effect on the planet.

I am an autonomous geologist who basically works in the Eastern Alps.I graduated in 2007 with a task that read how permafrost, i.e. frozen soil, reacts to new, more visual adjustments in the alpine environment.So, reading ancient maps, photographs and reports, I’ve taken an interest in the history of geology and how early geologists understood how the earth worked, writing blogs about it in my free time.Living in one of the ancient spaces of the first geological studies, I mix tours with maps, figures and ancient studies that are carried out there.But geology is more than an ancient or local science, as geological forces have shaped and still influence history around the world.
