Question: what is the range of the tsar bomba

title: Tsar Bomba
text: 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 ) . 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 . Sensors continued to identify the shockwaves after their third trip around the world . 

Answer: answer: A shock wave was observed in the air at Dikson settlement 700 km (430 mi) away; windowpanes were partially broken to distances of 900 kilometers (560 mi). Sensors continued to identify the shockwaves after their third trip around the world.
