Chicxulub again

The Deccan Traps eruptions were roughly contemporary with the Chicxulub event; enough that there has been a lot of argument about which caused the extinctions, and I'd wondered about whether the latter could have triggered the former, as the shock waves refocused on the other side of the planet. It seems not, though the shocks seem to have triggered extra eruptions along the way.

The latest tsunami model displays, among other things, the estimated position of India at the time. The latitudes match (20N vs 20S), but their best estimate for the longitudes doesn't have India and Chicxulub on opposite sides, by about 60 degrees. A little more evidence against my theory.
