A large group of children struck by lightning.

We report on the largest case to date of children with significant injuries from a single lightning strike. A retrospective analysis was done of the camping scene and injuries to 28 people (26 preadolescent girls and 2 adult supervisors) and 7 dogs from a documented lightning strike. Of the 35 victims sleeping in the tent, 4 girls and 4 dogs were fatally injured. The 2 adults were unharmed, but 23 of the children suffered injuries including burns (23), cataracts (8), macular holes (4), tympanic membrane rupture (2), and skull fracture (2). Many of these injuries occurred more frequently than would be expected from prior large reviews and reports.

Lightning safety guidelines.

On average, lightning causes more casualties annually in the United States than any other storm-related phenomenon except floods. Although 90% of those injured survive, they may have permanent sequelae and disability. Many of these people incur injuries or are killed by lightning because of misinformation and inappropriate behavior during thunderstorms. A few simple precautions can reduce lightning injury risk. To standardize recommended actions during thunderstorms, the Lightning Safety Group (LSG), composed of lightning experts from many lightning-related backgrounds, met at the American Meteorological Society meeting Phoenix, AZ, in January 1998 to collectively address personal lightning safety. This paper is a summary of the recommendations developed by the LSG.

A fifth mechanism of lightning injury.

The four classic electrical mechanisms of lightning injury cannot account for all injuries. A fifth mechanism, injury by a weak upward streamer that does not become part of a completed lightning channel, has long been postulated in the engineering literature by lightning researchers. This paper reports a case of death where injury from a weak upward streamer is strongly suspected following forensic investigation. Neither high voltage nor any of the previously accepted mechanisms of lightning injury can explain this incident.
