Over the past several months, small magnitude earthquakes have been located
at Mount St. Helens. The seismicity is similar to what was observed at this
volcano from July to December 2023. No significant changes have been
observed in other monitoring parameters and there is no change in alert
levels at this time. Mount St. Helens remains at normal, background levels
of activity. Small magnitude earthquakes located beneath Mount St. Helens
at depths well below sea level are generally thought to be associated with
pressurization of the magma transport system.
