Fascinating. At first I just thought this title was ridiculous, but basically the authors are saying that the magnetic properties of the core affect cosmic radiation detection, so therefore any massive anomaly deep in the earth's core would

1. have an effect on cosmic radiation detection, and 2. is also likely to precede widespread global seismic activity.

They adjusted the radiation detection data for global sunspot numbers and saw a correlation of the specific event of the 2010 Chile earthquake.

If this holds true for more events, a sort of "geophysical weather forecast" could be possible!

As far as I know sunspot count is just a feature you can see on photographs, yet it is also very strongly correlated with this cosmic radiation detection data.
