About Indo-Australia Plate stress.

• Indo-Australia plate is a major tectonic plate which contains Indian subcontinent and Australian continent.
• Recent study said that Indo-Australia plate will broke into 3 or more pieces due to collision into Eurasian Plate.
• North Eastern side of the plate moves at the rate of 5.6 cm per year and North Eastern side plate moves at 3.7 cm per year due to obstruction of Himalayas which cause difference in movement.
• The difference in movement cause stress in middle of plate near Sumatra and cause many Earthquake and chance of breaking up.
