Fulgurites are formed when lightning strikes the ground, fusing and vitrifying mineral grains. [7] The primary SiO 2 phase in common tube fulgurites is lechatelierite, an amorphous silica glass. Many fulgurites show some evidence of crystallization: in addition to glasses, many are partially protocrystalline or microcrystalline.
Following the atomic bombing of Hiroshima, it was discovered in 2016 that between 0.6% and 2.5% of sand on local beaches was fused glass spheres formed during the bombing. Like trinitite, the glass contains material from the local environment, including materials from buildings destroyed in the attack. The material has been called hiroshimaite ...
Nearly every lightning discharge will exhibit beading as the channel cools immediately after a return stroke, sometimes referred to as the lightning's 'bead-out' stage. 'Bead lightning' is more properly a stage of a normal lightning discharge rather than a type of lightning in itself. Beading of a lightning channel is usually a small-scale ...
Lightning injuries are divided into direct strikes, side splash, contact injury, and ground current. [1] Ground current occurs when the lightning strikes nearby and travels to the person through the ground. [1] Side splash makes up about a third of cases and occurs when lightning strikes nearby and jumps through the air to the person. [1]
Being hit directly by a lightning bolt and becoming part of the main channel of electricity flowing from the cloud to the ground is one of the least common ways to be struck by lightning, Dr. Mary ...
In fact, lightning can, and often does, strike the same place more than once. Lightning in a thunderstorm is more likely to strike objects and spots that are more prominent or conductive. For instance, lightning strikes the Empire State Building in New York City on average 23 times per year. [166] [167] [168]
By Dan Mennella A fireworks display on July 2 may be a bit premature for some, but Mother Nature apparently couldn't wait to get the show started in Gotham on Wednesday. A strong thunderstorm ...
A series of lightning strikes spidered across the New York City skyline the evening of Saturday, April 1, a few of which stretched from the World Trade Center into the clouds above in a dazzling ...
