From a Wiki page[1]:
The location of the Deccan Traps, for example, would have been close to the antipodal point of Chicxulub in the late Cretaceous; a sufficiently large asteroid impact might have sent shock waves around the planet sufficient to trigger an effect on weakened crust on the other side of the globe.
A while ago IIRC I read in a Scientific American article that it took some 800,000 years from the Chicxulub impactor to the Deccan Traps. Some of these things take a long time!

- tim333 11y agoThere seems quite a lot of uncertainty to the timing so they may have happened at the same time. I'm not sure how they date it but if its based on the position in 75 million years of sediment then a few 100,000 years may not be a big difference?
