That earthquake looks like it might have been pretty complicated. So some caution might be advised regarding claiming that it was predicted.

Basically, it looks to me like the 7.8 earthquake could be regarded as an "aftershock" of sorts related to several other earthquakes that occurred at the same location.

If you want to propose that you actually predicted those earlier ones then I myself would think that that is appropriate because I suspect that they were likely responsible for the 7.8. Enough strain was transferred from place to place in the fault zone by those earlier ones that the 7.8 finally occurred.

These are personal opinions and theories.
