No more phreatic explosions and ash-venting episodes have been observed since 23 March. Seismic activity has returned to a low level as well and zone C on the island was reopened for day-time visits.
However, the volcano shows strong sulfur dioxide emission, suggesting that fresh magma might be flowing into a shallow reservoir. During 24-26 March, extremely high levels of SO2 emission rates were measured, up to 4,594 tonnes per day, the third highest value measured in 10 years.
During the rest of the past week, levels were much lower at about 400 t/d average.
The Montserrat Volcano Observatory keeps hazard level at 2.

The lava dome on Montserrat is again growing. The latest USGS/GVP activity report summarizes the recent activity: "MVO reported that pyroclastic flows from the Soufrière Hills lava dome occurred during 11-18 June. One of the largest pyroclastic flows traveled W down Gages Valley; others originated from within the collapse scar. A thermal camera showed several hot areas on the lava dome, likely exposed from rockfall and pyroclastic flow activity. On 28 June a small lahar descended the Belham Valley, to the NW. The Hazard Level remained at 3." ... read all
