Imagine the death and destruction that could be avoided if we could predict cataclysmic events. well, scientists have found a link between cosmic radiation and seismic activity, potentially changing the future of earthquake prediction.
The main idea is that eddy currents in Earth's liquid core generate its magnetic field. This field deflects incoming cosmic radiation. So, if disturbances in Earth's liquid core cause large earthquakes. And if these disturbances in Earth's liquid core also alter its magnetic field, then levels of cosmic radiation observed at ground-based detectors would be affected.
Sure enough, increases in earthquakes above magnitude 3 occur 15 days after increases in secondary cosmic radiation!
