Mind-blowing Beauty and Deadly Nature of Lightening
A fascinating post about lightening: there seems to have been much more of it in the GTA this year. A friend of mine even had his house hit by it, causing $50 000 in electrical damage (mostly TVs and computers).
Lightning can be one of the most picturesque visions in nature, and the one of the most deadly occurrences when it strikes. Lightening flashes occur on earth about 100 times every second, traveling at speeds up to 60,000 m/s, and can reach temperatures of 54,000°F (30,000 °C), hot enough to fuse silica sand into petrified lightning — known as glass channels or fulgurites — which are usually hollow and can extend some distance into the ground.
