Abstract
The outcome of the analyses of some significant observations in the records of VLF sferics over Kolkata (Lat. 22.56° N, Long. 88.5° E) at 9 kHz during the occurrences of two large earthquakes on July 07, 2013 will be presented here. Discrete spike-type signals are obtained as the precursors of two earthquakes with magnitude M > 6. 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. © 2015, Editura Academiei Romane. All rights reserved.
