Triggering of the largest Deccan eruptions by the Chicxulub impact: Comment

The environmental crisis responsible for the terminal Cretaceous extinctions has been linked with either episodes of Deccan volcanism or the Chicxulub impact (see Bhandari et al., 1996; Keller et al., 2009; Schulte et al., 2010; Schoene et al., 2015). Richards et al. (2015) proposed a connection between the two events and suggested that there was a change in the Deccan magmatic system as a result of the impact that occurred on the other side of Earth (more than 13,000 km away). They suggested that the seismic waves resulting from the Chicxulub impact could have affected the magmatic system responsible for Deccan volcanism.
