Abstract

In our nuclear age, fears are expressed about the fate of the Earth's ozone layer, and it is believed that both large-scale and local nuclear conflicts can destroy the ozone layer for years. On September 22, 1979, an unidentified state secretly performed a nuclear test in a desolate region of the World Ocean. This event is commonly referred to as the Vela Incident. In this work, we used ozone data obtained by the NASA satellite Nimbus-7 17 minutes after the explosion. It is shown that the shock wave left a mark on the ozone layer. No decrease in the amount of ozone is noticed. The coordinates of the explosion site are determined from the mark.
