and what plates were inlvoved, please help i cant find this anywhere !?
Well, we would need to know which country (or countries) it occurred in.
It's really easy to find out information about earthquakes and other natural disasters, but it would help if you told us where it occurred.
India Plate slides under the overriding Burma Plate.
So, it was caused by subduction.
Remember the India plate is part of the Indo-Australian plate and Burma is part of the Eurasian plate.
thank you !
