ツァーリ・ボンバ
Sukhoy Nos cape, located at the southern end of the island, was used for nuclear weapons testing between 1958 and 1961. The Tsar Bomba hydrogen bomb test (October 30, 1961) destroyed all buildings in the village of Severny (both wooden and brick). The village was located 55 kilometres (34 miles) from ground zero within the Sukhoy Nos test range. Tsar Bomba was the most powerful nuclear weapon detonated and was the most powerful anthropogenic explosion in human history. It had a yield of 50 megatons of TNT, scaled down from its maximum 100 megaton design yield. Severny is now the site of a Russian Army base and has a harbor.
