What is the electronic apocalypse?

Solar storms occur when the Sun's magnetic activity is strongest, a maximum that occurs every eleven years. These phenomena can cause geomagnetic storms on Earth and affect satellite communications, navigation systems and power grids. Hence, there is talk of an electronic apocalypse, in the event that a solar superstorm occurs that fully affects us and disables these systems for an indeterminate time (according to some experts, up to two years).
Given our dependence on technology, its effects would be worse than the strongest solar storm ever recorded, which occurred in the summer of 1859. Called the Carrington Event , it disabled telegraphs in the US and Europe and caused auroras. that could be appreciated even in Spain. In 2012, President Obama even included solar storms among national threats .
