Soufriére Hills, Montserrat, West Indies

MVO reported no evidence of lava-dome growth at Soufrière Hills during 14-20 June. Seismic activity remained low. On 19 June, mild ash venting from the Gages vent (to the W) resulted in an ash plume that rose to an altitude less than 1.2 km (4,000 ft) a.s.l. and drifted E. The E talus slope continued to erode, producing minor rockfalls that descended into the Tar River Valley. The Alert Level remained elevated at 4 (on a scale of 0-5).
