Powerful solar superstorms can destroy undersea cables leading to massive Internet disruption lasting for several months.
A solar storm is a directional ejection of a large mass of highly magnetised particles from the sun. These magnetised and charged solar particles will interact with the earth’s magnetic field and induce strong electric currents on the earth’s surface.
The research notes that undersea cables have a higher risk of failure compared to land cables due to their large lengths as current is proportional to the area of the loop formed by the two grounds and the cable.
