Another, larger quake. The first one was shallow and strike-slip. This one is M6.6 and is thrust.

They are far enough apart and the magnitudes are small enough that the first is not a direct foreshock of the second. But logic says that they are related. But I doubt this is well-understood at all. It will be interesting to see how static stress changes on a shallow quake can weaken a deep part of the subducting slab. Is liable to be another process; for example, the seismic waves from the first initiated some sort of cascade.
I'm not an earthquake seismologist.
