Novaya Zemlya largest number of fjords in the Russian Federation. Novaya Zemlya separates the Barents Sea from the Kara Sea. The total area is about . The highest mountain is located on the Northern island and is 1,547 meters (5,075 ft) high. Compared to other regions that were under large ice sheets during the last glacial period, Novaya Zemlya shows relatively little isostatic rebound. Possibly this is indebted to a counter-effect created by the growth of glaciers during the last few thousand years. The ecology of Novaya Zemlya is influenced by its severe climate, but the region nevertheless supports a diversity of

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
