Any question answered...

Are the earthquakes in Mexico connected to the hurricanes?

It's not beyond the realms of possibility that a storm surge in the Caribbean could apply enough pressure to the Caribbean tectonic plate to trigger an earthquake, but it would be an earthquake which was going to happen soon anyway, because the underlying stress was already on the point of fracture. Shock waves from storms, explosions, other earthquakes or just somebody dropping a spanner can only change the timing of an earthquake, not it's location or magnitude.
