This quake is close enough to the Chile event to very possibly be related/triggered by it.
The rupture zone for the Chile event has spread a considerable distance along the subduction zone. this will keep seismologists and tectonists at it for a long time.
That's waaaaaay too catastrophic an image for my poor little mind to deal with.
Could an 8.8, followed by massive aftershocks really rip a country to shreds, or might that "falling apart" been a really serious mistranslation?
