Why does geyser erupt

As the steam bubbles become larger and more plentiful, they can no longer rise freely through the constrictions in the plumbing system. Temperatures build and the boiling becomes more turbulent. Eventually the violent bubbling forces some of the underlying water through the constriction. This release creates an instant reduction in pressure. Much of the water in the system flashes instantly into steam and forcibly ejects the remaining water. The character and function of a geyser are determined by its plumbing system and every geyser is unique.

At a depth of approximately 45 feet, the probe encountered a constriction that was barely four inches wide. Beyond this narrowing was an opening about the size of a large automobile.

Part 1. What natural processes govern the length, frequency, and behavior of geyser eruptions? There is a long history of searching for external controls on geysers, and studies often draw contradictory conclusions even for the same geysers. Uncontroversial are the observations that regional and distant earthquakes can change geyser behavior, including the interval between eruptions, and that some geysers, such as several in Yellowstone, display seasonal cycles of eruption intervals.
