Abstract
WHILE reporting the effects of nuclear explosions on the gravimeter installed in our laboratory, it was mentioned that possibly sometimes the free oscillations of the Earth could also be observed. It is obviously necessary that an adequate amount of energy will have to be communicated to the Earth for this to occur and in order to identify these oscillations the records have to be harmonically analysed. This is now being done.
