In some cases, the currents generated as CMEs interact with Earth’s magnetic field can temporarily block out radio communications and satellite navigation in certain areas.
In extreme scenarios, these currents can be so powerful that they overload electrical infrastructure, damaging the power grid and railway lines, and even sparking fires—resulting in billions in infrastructure liability insurance claims, legal investigations, and public health service disruptions.
However, events on that scale are extremely rare and have only hit Earth a handful of times in recorded history, such as during the 1859 Carrington Event.
