Anatomy of Old Faithful and Yellowstone; magma from earth's core to hot springs and geysers
We have conducted detailed seismic studies of the plumbing anatomy of Old Faithful, the iconic geyser of Yellowstone, to determine its 3D structure and dynamic eruption properties. These studies reveal that Old Faithful is located at the edge of large hydrothermal reservoir composed of highly fractured rock, hot water and steam located west of the geyser and extending a km beneath the Old Faithful Lodge and other infrastructure. We found that Old Faithful eruptions do not have a notable seismic signal but large seismic signals of a precursor tremor every 95 minutes just prior to the eruption ...
