摘要

Nayak et al.1 attempted to give a reason for the recurrence of seismic activities around the Koyna area, Satara district, Maharashtra (India), while estimating the thickness of the Deccan Flood Basalt around the area through inversion of aeromagneticand gravity data. However, they could not provide suitable explanation for many of the inferences and conclusions. For example, it is stated in the abstract and similarly in the conclusion that 'the entire column of lava below this region is made up of non-massive vesicular type of basalts having a low density of 2.58 g/cm~3 and a porosity of about 17%'. Such statements are utterly misleading and contradict the information obtained so far on the Deccan Flood Basalt.
