The presence of fulgurites in an area can be used to estimate the frequency of lightning over a period of time, which can help to understand past regional climates. Paleolightning is the study of various indicators of past lightning strikes, primarily in the form of fulgurites and lightning-induced remanent magnetization signatures. [1]
A lightning strike can also create a large Lichtenberg figure in grass surrounding the point struck. These are sometimes found on golf courses or in grassy meadows. [12] Branching root-shaped "fulgurite" mineral deposits may also be created as sand and soil are fused into glassy tubes by the intense heat of the current.
Vitrified sand is a type of natural glass, contrasted with manufactured glass in which soda ash or potash are added to lower the melting point. Pure quartz melts at 1,650 °C (3,002 °F). There are several natural processes that produce more or less melted sand and one man-made form: Fulgurite is sand fused by a lightning bolt hitting sand.
Vitrification of quartz can also occur when lightning strikes sand, forming hollow, branching rootlike structures called fulgurites. [18] Trinitite is a glassy residue formed from the desert floor sand at the Trinity nuclear bomb test site. [19]
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 ...
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 ...
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 ...
