7.2 or 7.4 - it makes no difference

Time to pray, folks, for the people of Japan - they have just endured another large quake with an additional tsunami warning.

What I can't figure is why this would be considered an "aftershock" instead another independent quake.

Of course, it makes no difference whatsoever....aftershock or quake. It's all the same and it is all devastating and horrible, and I pray for those people suffering there. I encourage you to do the same.

If you're not a praying person, then please think good thoughts and send positive energy to that country and her people. And while you're at it, please send the same prayers, thoughts and vibes for Mexico...I understand they have just experienced another large quake of their own.
