Intense magnetic interference from solar storms messes with our planetary magnetic field and 'disturbs' our magnetic core. Who woulda thought ?
From Space.com ): Earthquakes seem more intense after cosmic ray strikes. Scientists say this is why.
Hidden mechanisms that give rise to powerful earthquakes may also allow more cosmic radiation to reach the planet's surface.
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.
The team said that they ruled out the possibility that the observed correlation was down to chance alone.
Scientists think that the strange correlation between cosmic radiation and seismic activity could be explained by the behavior of eddy currents in the liquid core of our planet which drive the generation of
Earth's magnetic field. This field, also known as the magnetosphere, is responsible for deflecting charged particles which make up cosmic radiation.
