Earth seems to shake more after intense cosmic radiation hits its surface, a new study suggests.
The surprising study by a team of Polish researchers analyzed 50 years worth of data and found that the intensity of global seismic activity correlated with the average variation in the intensity of secondary particles created by cosmic radiation with a time lag of around two weeks. Secondary cosmic radiation is produced by the interactions of cosmic rays and Earth's atmosphere, which suggests that the link between the two phenomena may have nothing to do with the intensity of the arriving cosmic rays but rather with their ability to breach Earth's defenses.
