Siberian Shelf Siberian Shelf The Siberian Shelf, one of the Arctic Ocean coastal shelves (such as the Milne Ice Shelf), is the largest continental shelf of the Earth, a part of the continental shelf of Russia. It extends from the continent of Eurasia in the general area of North Siberia (hence the name) into the Arctic Ocean. It stretches to offshore. It is relatively shallow, with average depth of 100 m. A number of islands are within the shelf, including the Wrangel Island, Novaya Zemlya, and the New Siberian Islands. It is encompassed by the Kara Sea, Laptev Sea, and East Siberian
Novaya Zemlya Novaya Zemlya. The launch rocket was subsequently deployed to Cuba. 1963 saw the implementation of the Limited Test Ban Treaty which banned most atmospheric nuclear tests. The largest underground test in Novaya Zemlya took place on September 12, 1973, involving four nuclear devices of 4.2 megatons total yield. Although far smaller in blast power than the Tsar Bomba and other atmospheric tests, the confinement of the blasts underground led to pressures rivaling natural earthquakes. In the case of the September 12, 1973, test, a seismic magnitude of 6.97 on the Richter Scale was reached, setting off an 80 million ton
