MVO reported that during 3-10 October, the activity level at the Soufrière Hills lava dome was slightly higher than the previous week and consisted mainly of rockfalls and mudflows. As a result of slow and continuous erosion of the lower part of the dome, rockfalls occurred on both the W side in the gully over Gages Wall and on the E side in the Tar River Valley. The rate of lava extrusion had declined significantly. Thermal imagery captured during an overflight on 8 October revealed that a major E-W oriented fracture in the dome, aligned with the Gages Valley and extending vertically over a few tens of meters, was associated with very elevated temperatures. Several other very hot areas were also detected. These areas were visible using binoculars from MVO later that night. The Hazard Level remained at 3.
