India was located near the antipode of the Chicxulub crater. A meteor impact could explain the volcanic activity on the opposite side of the Earth from the impact.
Could impact cause a volcano on Earth?We believe that broken comets or asteroids - such as machined gunned into Jupiter in 1994 - have hit the Moon (forming an impact crater chain), and a recent scientific report suggests that a line of old impact craters across the central USA was caused by a similar line of impact collisions. In these cases volcanism was not triggered. A big enough impact might trigger volcanic activity, and one scientist suggested that that might be the origin of Iceland, which is very big compared to other ocean hot-spots.

Considering the Deccan traps formed 3 million years before the alleged impact and the location antipodal to the Deccan Traps at the time of their formation is now on the floor of the eastern Pacific Ocean that would be a good trick
