On Sept. 22, the aviation warning code was raised to yellow and an advisory issued to the general public.
“The current earthquakes are small, generally less than magnitude 1.0, and are located at shallow depth beneath the volcano’s summit,” the observatory said in its original message. “While significant, the current earthquake activity is much less energetic than that which immediately preceeded the explosive eruptions in January 2006.”
