SUMMARY On 1986 August 1 a small seismic disturbance occurred to the east of a Soviet nuclear test site at Novaya Zemlya. Reported attempts to identify the nature of the source using only short‐period seismological data recorded at regional distances were unsuccessful. However, by using teleseismic P‐wave data it is possible to identify the source as an earthquake which occurred within the crust at a depth of 24 km. The source is shown to have a double‐couple mechanism with a well‐constrained fault‐plane solution. The identification as an earthquake is supported by the m b : M s evidence.
