Mexico stunned the world by defeating current World Cup title-holders Germany in their first match of the tournament yesterday and when fans started celebrating, they stunned seismologists by causing what scientists are calling an 'artificial earthquake'.

Chucky Lozano put himself firmly in the history books of Mexican sport by scoring the only goal of the match just inside the first half, and this is what the reaction looked like.

Such was the reaction that local officials said it registered on the Richter Scale, claiming that an "artificial quake" was reported in Mexico City probably caused by "massive jumps during the goal from the Mexico national soccer team."

Field geophysicist and writer Mika McKinnon broke down the science of what actually happened.

Other experts also shared the seismic data which shows just how big the stomping was.

One thing's for sure, you can't say the Mexican football fans aren't passionate.
