Curious - how do they know lightning hit four times? Was someone outside counting?
- sz4kerto 11y agoBuilding power management systems can detect this.
- cdr 11y agoAs sz4kerto said, it was probably tracked by building systems. But beyond that, weather services track every single lightning strike in most of the developed world. Eg BELLS: http://radar.meteo.be/en/3337408-Lightning+detection.html#ppt_10819449 http://radar.meteo.be/en/3337408-Lightning+detection.html#pp... This is how, for example, you can know whether a wildfire was started by lightning - once a point of origin is determined, simply check the data for strikes. https://en.wikipedia.org/wiki/Lightning_detection https://en.wikipedia.org/wiki/Lightning_detection http://www.lightningmaps.org/ http://www.lightningmaps.org/
