Severny Island is a massive landmass located in the Russian Arctic. It serves as the northern island of the Novaya Zemlya archipelago. This island sits approximately 400 km north of the Russian mainland. It is a significant part of the Russian Arctic National Park. This park also includes Franz Josef Land, which lies further north. Severny is the 30th-largest island in the world. It is also the 3rd-largest uninhabited island on Earth. While it is mostly empty, a settlement once existed at Lagerni. This former settlement was on the northern shore of the Matochkin Strait.

The geography of the island is defined by water and ice. Severny Island is separated from Yuzhny Island by the narrow Matochkin Strait. A huge portion of the land is covered by frozen water. The Severny Island ice cap covers 40 percent of the total area. This ice cap is very large. It is the largest glacier in Europe by both area and volume. The island is also famous for its many other glaciers. Most of these glaciers have a terminus, or end point, on the eastern or western shores.

The climate on Severny Island is extremely harsh. It is classified as a cold tundra climate. In science, this is called a Köppen climate classification ET. This means the weather is very cold for most of the year. Even during the warmest months, temperatures barely reach the freezing mark. The temperature changes significantly between the seasons. Winter temperatures are very low, while summer temperatures remain near freezing. This environment makes the island a very difficult place for life to thrive.

Explorers have studied this remote region for many years. The island was historically known as Lütke Land. This name was given to honor Friedrich Benjamin von Lütke. He was an explorer who helped discover the area. Today, the island has several important geographic landmarks. Cape Flissingsky marks the easternmost point of the island. Cape Zhelaniya is the northernmost point. Sukhoy Nos serves as the most westerly point.

The history of the island includes a period of intense nuclear testing. Between 1958 and 1961, the area of Sukhoy Nos was used for these tests. Sukhoy Nos is located at the southern end of the island. On October 30, 1961, a major test occurred. This test involved a hydrogen bomb known as the Tsar Bomba. This was the most powerful nuclear weapon ever detonated. It was also the most powerful anthropogenic explosion in human history. The explosion had a yield of 50 megatons of TNT. This was a scaled-down version of its 100 megaton design.

This explosion had a devastating impact on the local area. The village of Severny was located 55 km from ground zero. Ground zero is the point where the explosion happens. The blast was so strong that it destroyed all buildings in the village. This included both wooden and brick structures. Because of this event, the village of Severny no longer exists. The landscape was permanently changed by the force of the blast. This remains a heavy part of the island's recent history.

Despite its difficult history, the island remains in use today. There is currently a Russian Army base located on the island. This base also includes a harbor for ships. At the northernmost cape, Cape Zhelaniya, there is a meteorological station. This station tracks the weather and climate of the Arctic. The island continues to be a place of scientific and military interest. It remains a remote and icy part of the Russian Arctic.
