Mars Opposition

Ok so Mars will be in "opposition" tomorrow April 8, 2014. I understand that apparently this only happens once every two years or so?

So GLP, I have a mission for you. Do some research, and find out when EXACTLY, the last "opposition" was.

Once you have that date and timeframe. Then find out if any major earthquakes occurred around the same time. When I say major I mean 7+. Alright go!
