But after several hours of anxiety, the world did not show any signs of ending and as the giant anvil-shaped cloud that spanned several miles of the sky for about an hour began dispersing, people calmed down gradually, and returned to their daily petty preoccupations.
reports the cloud formation occurred at 7 p.m. on June 14.
According to News Yahoo!
thousands of photographers and videographers lined the streets, capturing images of the formation that an observer described, saying it "gradually took the shape of an atomic bomb."
reports that experts at the National Center for Atmospheric Research, say the ominous formation was a giant cumulonimbus
thunderstorm cloud that forms from a towering cumulus and "resembles the head of a cauliflower."
reports experts say that even the smallest cumulonimbus clouds dwarf other types of cloud because they typically have a base that is several miles across.
