>>>I just checked, using EARTHQUAKE 3D and the Mexico Quakes are almost directly opposite the Indonesian Quake. I.E. its where the waves from the Larger quake meet on the opposite side. IIRC, its typical to have such a result.
That science concept of action/reaction is over-rated.... < /sarc.>
SO.... have you used EARTHQUAKE 3D ? If not, I bet you would really like it.
