| Note: | Middle Sister is active today and was probably active prior to this based on observations from me, Rocco Paperiello, and David Schwarz, who saw one eruption on 8/21/17. Middle Sister eruptions consist of a single burst that may vary in height from 2 to 8 feet. Mugwump has been inactive for a number of days but is still hot. MYR-1 has been seen boiling but no eruptions have been reported. Three Crater is still frequent and sometimes having energetic eruptions to as much as 6-8 feet. |
