Bangkok: Academics have clarified that a recent lightning strike on a motorcycle was caused by the vehicle's high elevation and not by any personal items such as a necklace or mobile phone.
According to Thai News Agency, Associate Professor Dr. Jessada Denduangboriphant from the Department of Biology, Faculty of Science at Chulalongkorn University, explained the circumstances surrounding the event where a motorcyclist was struck by lightning.
While traveling on the Ratchavipha elevated bridge above Vibhavadi Rangsit Road towards the Ratchayothin intersection, the motorcycle lost control and crashed, leading to severe injuries for the rider. The individual suffered burns on the neck due to a stainless steel necklace, which fell onto his chest, as well as burns to the ears and head.
Professor Jessada emphasized that the lightning strike was not precipitated by the necklace, helmet, or motorcycle. Instead, the vehicle's position on an elevated bridge made it a target for the lightning, which would have otherwise struck another vehicle in its path. The burn marks along the necklace line were due to the metal's conductivity, which induced heat and caused the burns, rather than attracting the lightning itself.
This phenomenon is akin to mobile phones burning or exploding when hit by lightning, a consequence of the electrical current rather than any attraction to the lightning. The incident highlights the increased danger for motorcycle riders during thunderstorms compared to car drivers. Cars provide a protective structure that channels the current to the ground, whereas motorcycles leave riders exposed to direct shocks.
Dr. Jessada advises motorcycle riders to avoid elevated or open areas during storms and to seek shelter in sturdy buildings or under bridge structures, avoiding trees or signs that are prone to lightning strikes or collapse.
