Millions were left powerless in Spain, Portugal and France on April 28 after what officials called an “induced atmospheric vibration,” or a rare phenomenon where weather changes affect power lines.
The outage was centered in Spain, where the lack of power caused widespread chaos. Renfe, Spain’s national railway company, said on social media that the “entire national electricity grid was cut off” at 12:30 p.m. local time.
It brought parts of Spain and Portugal to a standstill, grounding planes, halting public transport and forcing some hospitals to suspend routine operations.
According to a report from the BBC, Portuguese energy company REN suggested that “due to extreme temperature variations in the interior of Spain, there were anomalous oscillations in the very high voltage lines (400 KV), a phenomenon known as ‘induced atmospheric vibration.'”
