Drought Causing Old Faithful to be Less Faithful
A new study suggests that geysers, like Old Faithful, are affected by climate conditions, such as droughts. Shaul Hurwitz, a researcher with the U.S. Geological Survey, Ashish Kumar, a Stanford University statistician, and two National Park Service scientists have discovered that changes in the supply of underground water to a geyser can influence the amount of time between eruptions. “Coupled with this decrease in precipitation, we see an increase in eruption intervals with all the geysers we analyzed,” explained Hurwitz.
