MVO reported that during 29 August-5 September, data suggested that the W side of the Soufrière Hills lava dome continued to grow. Lahars and rockfalls dominated the activity. Lahars likely descended the Tar River valley on 29 and 31 August. On 1 September, a lahar descended the Belham River valley to the NW; the event lasted approximately 50 minutes. A new vent on the NW part of the lava dome, a little further N of the previous Gages vent, was observed during an overflight on 4 September. The smell of volcanic gases was occasionally noticed when the wind blew N and NE. The Hazard Level remained at 3.

A new lava extrusion from Soufrière Hills started from the W side of the lava dome between the 28 July lava-dome collapse event and 8 August, when a new channel of fresh rockfall material was seen below Gages Wall. During 8-15 August, seismicity and the rate of lava extrusion were generally low and sulfur dioxide emissions were elevated. On 14 August the W side of the dome was visible and the explosion crater that was generated on 28 July was almost completely filled with new lava. Lava spilled over the lower and W side of the crater and generated rockfalls below Gages Wall that were observed and heard from St. George's Hill. During 14-15 August, the scent of volcanic gases was noticeable at times in inhabited areas of Montserrat. The Hazard Level was 3.
