What is the Source of the Carbon Dioxide?
There may be a link between elevated levels of carbon dioxide and seismic activity that occurred at Mammoth Mountain during the fall of 1989. Carbon dioxide, a naturally occurring gas in magma, appears to be making its way to the surface, possibly from an intrusion of magma at great depths. There is no seismic data to support the theory that this venting of gas indicates increasing chances of an eruption. Researchers believe that there would be more seismic activity in the vicinity of Mammoth Mountain if an eruption were imminent.
