        abstract = {The outcome of the analyses of some significant observations in the records of VLF sferics over Kolkata (Lat. 22.56º N, Long. 88.5º E) at 9 kHz during the occurrences of large earthquake on August 14, 2021 will be presented here. Discrete spike-type signals are obtained as the precursors of this earthquake with magnitude M>7. The number of spikes and their intensities are found to vary irregularly and reached their maximum value on the day of occurrence. It then decreases gradually and finally ceased.},
