Geysers

Abstract

Geysers, springs that intermittently erupt boiling water, appear to be especially sensitive to earthquakes. As they are a surface manifestation of geothermal systems, their response to earthquakes provides a window into how earthquakes change hydrothermal systems and processes. The most common approach to document responses to earthquakes is to identify changes in the interval between eruptions. Sustained changes in eruption intervals may be caused by changes in permeability. Confirming what processes lead to changes at geysers is hampered by limited reliable, quantitative multi-parameter data sets.
