Low level eruptive activity that began almost two years ago continues at Veniaminof. On November 15, residents of Perryville began hearing rumblings and booms, which continued through the early evening. They also observed minor ash emission (reported as "smoking" by observers), as well as an increase in steaming. Minor steam and ash emission was observed as recently as yesterday, November 30. Veniaminof was obscured by clouds on satellite imagery of November 15, and no hot spot was visible during the last week.
