Using nonlinear dynamics to predict Old Faithful

Keywords--Logis t ics map, Geyser eruptions, Nonlinear dynamics, Old Faithful. 1. I N T R O D U C T I O N A N D P R O B L E M M O T I V A T I O N Old Faithful, the most famous geyser in Yellowstone National Park, is known for the regularity and predictability of its eruptions. Predictability, however, has many gradations. Although it is possible to predict an eruption after observing the previo...

Mechanics of Old Faithful Geyser, Calistoga, California

[1] In order to probe the subsurface dynamics associated with geyser eruptions, we measured ground deformation at Old Faithful Geyser of Calistoga, CA. We present a physical model in which recharge during the period preceding an eruption is driven by pressure differences relative to the aquifer supplying the geyser. The model predicts that pressure and ground deformation are characterized by an...

The plumbing of Old Faithful Geyser revealed by hydrothermal tremor

Old Faithful Geyser in Yellowstone National Park (USA) has attracted numerous scientific investigations for over two centuries in order to better understand its geological structure, the physics of its eruptions, and the controls of its intermittency. Using data acquired with a seismic array in 1992, we track the sources of hydrothermal tremor produced by boiling and cavitation inside the geyse...
