Earthquake clouds are clouds claimed to be signs of imminent earthquakes. They have been described in antiquity: In chapter 32 of his work Brihat Samhita, Indian scholar Varahamihira (505–587) discussed a number of signs warning of earthquakes, including extraordinary clouds occurring a week before the earthquake. In modern times, a few scientists claim to have observed clouds associated with a seismic event, sometimes more than 50 days in advance of the earthquake. Some[according to whom?] have even claimed to accurately predict earthquake occurrences by observing clouds. However, these claims have very little support in the scientific community.
