The Earth is a rotating ball that is not completely solid and can bulge. Global warming is causing the greenland ice pack to melt and the Earth is losing a lot of mass (weight) in the area of greenland. On the opposite side of the Earth from Greenland is the Australian plate. The 2004 Tsunami was caused by the Indian plate moving under the Australian plate or the (burma microplate region).
The Earth being a rotating ball, the lessening of the weight at greenland, as it melts, is causing the Australian plate region to bulge with centrifugal force, because it is no longer counterbalanced by greenland. This is lifting up the Australian plate allowing the Indian plate to move under it faster. Thus causing the earthquake and tsunami. Another major quake happened in the region since then. I believe this region and the whole Indian plate rim will continue to be an increasingly active earthquake region as greenland continues to melt with global warming.
Earth quakes generally happen within a short while after eclipses of the sun or moon. So, if a total eclipse passes over the region of the Indian plate or Australian plate, look for a major earthquake within about 2 months after that.
