MVO reported that during 23 November-3 December the lava dome at Soufriére Hills changed very little, based on visual observations. Seismic activity was very low and low-level rockfall and pyroclastic flow activity continued. Fumarolic activity on the N and E flanks of the dome were observed. On 29 November, a regional M 7.4 earthquake occurred at 1500. A few minutes later, a small pyroclastic flow traveled down the E flank. At 1530, three more pyroclastic flows traveled E down the Tar River Valley. The Alert Level remained elevated at 4 (on a scale of 0-5).
