Soufrière Hills, Montserrat: volcano news & activity updates

Soufrière Hills volcano (Montserrat), activity update: increased dome growth, vulcanian explosions

MVO reported that during 8-15 January activity from the Soufrière Hills lava dome increased significantly. One explosion on 8 January and two on 10 January generated ash plumes that rose to altitudes of 5.5-7.6 km (18,000-25,000 ft) a.s.l. Ash fell in occupied areas to the NW, along with lapilli fall on 10 January. The explosions occurred from an area on the NE side of the volcano. Pyroclastic flows from column collapses moved rapidly NE (down Whites Bottom and Tuitts Ghaut), NW (down Tyers Ghaut and Belham Valley), W (down Gages Ghaut), and the SE (down the Tar River Valley). After the explosions activity decreased until 12 January, when cycles of increased numbers of rockfalls, pyroclastic flows, and ash venting were noted.
Observations during 8-15 January revealed that lava-dome growth resumed at the top, central part of the dome. On 18 January, a partial lava-dome collapse generated a pyroclastic flow that traveled W down Gages Valley, into Spring Ghaut, and then WSW down Aymers Ghaut, reaching the sea. Ash plumes rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted W. Smoke from burning houses in Kinsale was visible after the event. The Hazard Level remained at 4.

It was reported that during 2-3 January activity from the Soufrière Hills lava dome increased drastically. On 2 January, a pyroclastic flow traveled down to Tyers Ghaut (NW) and to to the upper part of Belham River. On 3 January two explosions produced ash plumes to high altitudes and ashfall affected most of the island The strong explosions reached to at least 500 m above the dome. In-column collapses resulted in pyroclastic flows. The level of activity decreased dramatically after the second explosion. ... read all

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. ... read all
