闪电击中后的痕迹

闪电击中留下的“纹身”

被闪电击中留下的“纹身”, 会维持数小时或数天。这是因为电流使到皮肤下的 毛细血管破裂形成的纹路。这也是法医用来确认因闪电击中而亡的方法。
"Getting hit by lightning gives you a special scar.
Lasting on the skin for hours or days, the Lichtenberg Figure is caused by the rupture of capillaries under the skin when the lightning current passes through it. They're a major way that forensic scientists can tell a lightning victim's cause of death."
