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!

There's also earthquake lights,

> a luminous aerial phenomenon that appears in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions

Since cosmic rays contribute to cloud formation does that mean strange clouds can be precursors to earthquakes!?

I skimmed the paper. No mention of Martian quakes. NASA has data. Does it also correlate with cosmic rays?

There is a Youtube account that tracks cosmic rays and has additional theories on how earth quakes chain through fault lines. I became aware of him after he called the Turkey quake.
