This figure shows a map of the test site in the Thar dessert. This is the second nuclear test conducted by India since May 18, 1974.

This figure shows the frequency-wavenumber (f-k) analysis of the seismic signals recorded at the GERESS array. The bright spot determines the direction and the velocity of the seismic signal arriving at the GERESS array. This data can be used to locate the origin of the nuclear explosion.
