 The spectacular scale of a Giant eruption, combined with relatively frequent activity in recent years, has caused the geyser to be the object of much study and much has been learned about its eruptive behavior.Giant steams and splashes even during inactive periods, but eruptions can happen only during so-called "hot periods" when there are changes in the activity of the other springs on the Giant Platform as well as more intense splashing in Giant itself.Hot periods typically last a few minutes, and most do not lead to an eruption.
