re: Is there any footage of a modern day nuclear test explosion?

The Tsar Bomba was the biggest nuclear weapon ever detonated. Obviously we can create bombs now with a more powerful yield/material but we don't need bombs like the Tsar Bomb, because it's pointless levels of destruction

The most powerful bomb ever was tested in the 50s

Tsar Bomba (Russian: ????-?????; "Tsar-bomb", or "King of bombs") was the Western nickname for the Soviet RDS-220 hydrogen bomb (code name Ivan[3] or Vanya), the most powerful nuclear weapon ever created. Its test on 30 October 1961 remains the most powerful explosive ever detonated. It was also referred to as Kuzkina mat (Russian: ???????? ????; "Kuzma's mother"),[4] possibly referring to First secretary Nikita Khrushchev's promise to show the United States a Kuzkina mat (an idiom roughly translating to "We'll show you!") at a 1960 session of United Nations General Assembly.[5][6]

The original, November 1961, AEC estimate of the yield was 55–60 megatons, but since 1992, all Russian sources have stated its yield as 51 megatons. First secretary Khrushchev warned in a filmed speech to the Supreme Soviet of the existence of a 100 megaton bomb. (Technically the design was capable of this yield.) Although simplistic fireball calculations predicted the fireball would hit the ground, the bomb's own shock wave reflected back and prevented this.[21] The fireball reached nearly as high as the altitude of the release plane and was visible at almost 1,000 km (620 mi) away from where it ascended. The mushroom cloud was about 64 km (40 mi) high (over seven times the height of Mount Everest), which meant that the cloud was above the stratosphere and well inside the mesosphere when it peaked. The cap of the mushroom cloud had a peak width of 95 km (59 mi) and its base was 40 km (25 mi) wide.[22][23]

All buildings in the village of Severny (both wooden and brick), located 55 km (34 mi) from ground zero within the Sukhoy Nos test range, were destroyed. In districts hundreds of kilometers from ground zero wooden houses were destroyed, stone ones lost their roofs, windows, doors, and radio communications were interrupted for almost one hour. One participant in the test saw a bright flash through dark goggles and felt the effects of a thermal pulse even at a distance of 270 kilometres (170 mi). The heat from the explosion could have caused third-degree burns 100 km (62 mi) away from ground zero. A shock wave was observed in the air at Dikson settlement 700 km (430 mi) away; windowpanes were partially broken to distances of 900 kilometres (560 mi).[24] Atmospheric focusing caused blast damage at even greater distances, breaking windows in Norway and Finland. Despite being detonated 4.2 km above ground, its seismic body wave magnitude was estimated at 5–5.25.[10][21] Sensors continued to identify the shockwaves after their third trip around the world.[11][25]
