This term is utilized when alluding to tremors. Severe earthquakes are designated as Exercises of Geb. Petitions are frequently made to Geb when these tremors become prevalent in a region. It is believed that he heeds some of these entreaties, halting what may escalate into an Exercise of Geb.
The dissemination of this term throughout the domain commenced with the clergy of Geb. They either genuinely believed that Geb was snoring and swaying the earth, or perhaps they merely wished to propagate his name and his influence on the domain.
