Megaton nuclear underground tests and catastrophic events on Novaya Zemlya : A satellite study

Abstract

During the first NUPI study of the Novaya Zemlya underground nuclear test site in 1991–92, much information was generated. This relates both to facilities and testing activities. One of the most important discoveries made was the enormous catastrophic rockslide caused by an underground test. In recent years, new information has become available also from Russian sources. Declassified US satellite imagery made it possible for NUPI to study in more detail the effects of the powerful underground nuclear tests on Novaya Zemlya. This report contains the most pivotal discoveries and findings during the three years of studying this arctic test site.
