Plate tectonics

http://earthquake.usgs.gov/earthquakes/recenteqsww... is this the start of something on the other end of the north American plate? As going by the link above that's 2 quakes in a short space of time since the Japan one.

No doubt the whole plate is upset. But that area is also on a plate boundary and common for tremors anyway.

The effect of tide on plate tectonics is not a well researched field (at least it wasn't when I was at university). But it's entirely plausible that it could have an effect -the water moved around by the tides does carry a hell of a lot of weight.

Isn't the whole point that it doesn't carry more 'weight' as the opposing gravitational forces create the bulge?
