I like the thought of jumping for joy, of arms raised, fists pumped; of running in circles because you don’t know what else to do with yourself; because there’s just so much good feeling it won’t stay put, must bubble out — all the physical expressions of positive emotion.

I didn’t know until yesterday, though, that when enough people jump for joy at the same time, it can actually cause an earthquake. Not a monstrous one, but one that can be detected on seismic read-outs like the one above. Apparently this happened on Sunday in Mexico, when cheering fans erupted with jumping and dancing when Mexico upset Germany in World Cup soccer play.

And it’s not the first time. A seismograph a block away from where the Seattle Seahawks scored the winning touchdown in the 2011 Super Bowl registered what it called the “12 Man Earthquake” or “the Beast Quake.” (This from my favorite weather site, The Capital Weather Gang.)

I bet there were some mini-tremblors in D.C. week before last when the Caps won the Stanley Cup. And I’m not ruling out seismic activity in Lexington, Kentucky, in late March or early April of  1978, 1996, 1998 or 2012, all recent wins of the NCAA Men’s Basketball Tourney.

Human-made quakes? Why not? They underline our connection with the earth, our influence over it, that it shakes and shimmies and trembles with our joy.
