Brian,
what I forgot to say is that I don't think that seismologists/earthquake geologists know when a tiny quake will cascade to a big one. So, presumably if you can trigger a M2 by passing seismic waves, then you can trigger a M7 or whatever. It would just be rare, because most small quakes are just that. To trigger a 7 it would really have to be ready to go, and not have been already set off by some other stronger effect.
