Activity at the volcano remains low. There were 3 rockfalls and 2 volcano-tectonic earthquakes.
At 4.30pm a pyroclastic flow signal was recorded on the seismic network. Observations suggest that a pyroclastic flow, probably generated by dome collapse, travelled down the Tar River valley and reached the sea. Poor visibility during and after the event hampered further observations. A significant ash cloud was generated by the event and was rapidly blown to the north west by strong winds. The dome is still in an unstable configuration and dome collapse events may occur without warning at any time. The Tar River valley, Gages valley and Fort Ghaut are the areas most likely to be affected by such events.
Residents of Montserrat are advised to keep listening to ZJB Radio Montserrat for information relating to any further developments in the state of the volcano.
