What plate boundaries were included in the Gujarat earthquake? (2001)?

I’ve had one result which says that the quake was caused by interplate movements or somehting and that it wasn’t really any specific plate boundaries which caused this, and one result which says that it was the collision on the Eurasian and the Indian :s Someone help! I will be eternally grateful!

According to the website I list below, the area is in a transition zone between a seismically active area and a stable landmass area, so arguments could be made for either viewpoint. Without more familiarity with the area, I cannot say for sure what the correct interpretation is.
