During 24 September to 1 October, low-level tremor and intermittent small tremor bursts may have occurred at Veniominof, but high winds in the area made analysis of seismic records inconclusive. The winds were strong enough to produce an overshadowing effect on seismic records that could hide evidence of low-level tremor. If the tremor episodes continued, they likely represented low-level ash-and-steam emissions similar to those observed over the previous 4 months. Read all- More about Veniaminof volcano

Low-level tremor and intermittent tremor bursts continued at Veniaminof during 17-24 September.

Elevated seismicity continued at Spurr during 17-24 September, with an average of ten earthquakes occurring within 30 km of the summit daily. The combined output of carbon dioxide from one vent at Crater Peak and one at Spurr was approximately 2,300 tons on 15 September, an increase from the approximately 760 tons/day measured during 7-8 August. AVO reported that the gray color of the lake at the bottom of the ice cauldron is typical of crater lakes containing dissolved sulfur dioxide. Read all- More about Spurr volcano

Volcanic and seismic activity at Soufrière Hills remained slightly elevated throughout 17-24 September. The seismic network recorded two rockfalls, two long-period earthquakes, and eight hybrid earthquakes. The sulfur-dioxide flux averaged 312 metric tons per day, reaching a maximum of 454 metric tons on 18 September. Read all- More about Soufriere Hills volcano

Seismicity was above background levels at Shiveluch during 23 September to 1 October, with 26 strong shallow earthquakes up to M 2.3 recorded during 23-29 September. Several explosions were seen that produced ash plumes to a maximum height of 4.5 km a.s.l., while interpretations of seismic data suggested that plumes rose to 6.5 km a.s.l. [Correction: According to interpretations of seismic data there were ~20 ash plumes at heights between 4 and 6.5 km a.s.l. Read all- More about Shiveluch volcano
