Soufrière Hills volcano (Montserrat), lava dome growth and small pyroclastic flows

During 17-24 November, lava-dome growth at Soufrière Hills continued and was concentrated on the NE part of the edifice. Ash venting originated from the westernmost of two cracks in the curved back of the shear E-facing lobe on the summit. Rockfalls and small pyroclastic flows traveled down the SW and NE flanks. Pyroclastic flows reached both the upper region of Tuitts Ghaut (N) and the sea via the Tar River Valley (E) on 23 November. An explosion produced an ash plume that rose to altitudes of 1.5-1.7 km (4,900-5,600 ft) a.s.l.
