The process begins as water migrates to the geyser's plumbing system through fissures in ground. Here is the process of a geyser eruption: 1. The eruption will continue until all the water is forced out of the tube, or until the temperature inside the geyser drops below boiling (100 degrees Celsius, or 212 degrees Fahrenheit, at sea level).After the eruption, water slowly seeps back into the tube.
