The Atmosphere-Space Interactions Monitor (ASIM), dedicated to measuring simultaneously optical signals of lightning and signals of terrestrial gamma-ray flashes, revealed that TGFs are usually associated with optical flashes, strongly suggesting that relativistic electrons as precursors of TGFs are produced in the strong electric fields in the ...
The attacks first consisted of GIF images flashing at high speeds that were hidden in discussion threads with innocuous-sounding titles. Later attacks redirected web browsers to a page with "a more complex image designed to trigger seizures in both photosensitive and pattern-sensitive epileptics."
An earthquake light also known as earthquake lightning or earthquake flash is a luminous optical phenomenon that appears in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions. [1] There is no broad consensus as to the causes of the phenomenon (or phenomena) involved.
Lash Lightning is a fictional superhero character who first appeared in Sure-Fire Comics #1 (June 1940) from Ace Comics, [1] which was renamed Lightning Comics with issue #4 to take advantage of the new character's popularity.
Global map of lightning frequency--strikes/km 2 /yr. The high lightning areas are on land located in the tropics. Areas with almost no lightning are the Arctic and Antarctic, closely followed by the oceans which have only 0.1 to 1 strikes/km 2 /yr. The map on the right shows that lightning is not distributed evenly around the planet. [5]
The flash of a lightning strike and resulting thunder occur at roughly the same time. But light travels 300,000 km/sec, almost a million times the speed of sound. Sound travels at the slower speed of about 340 m/sec (depending on the temperature), so the flash of lightning is seen before thunder is heard. A method to determine the distance ...
A power flash is a flash of light caused by arcing electrical discharges from damaged electrical equipment, most often severed or arcing power lines. They are often caused by strong winds, especially those from tropical cyclones and tornadoes , and occasionally by intense downbursts and derechoes .
The Flash (Bartholomew Henry "Barry" Allen) is a superhero appearing in American comic books published by DC Comics. He is the second character known as the Flash, following Jay Garrick.
