Over the last 24 hours the level of volcanic seismicity has decreased. Overnight there were higher levels of both rockfall signals and volcano-tectonic earthquakes than was normal before the collapse on Friday morning. As the day has gone on, however the number of these events has decreased and seismicity is presently at a lower level.
Over the reporting period there have been 24 rockfall signals and 11 volcano-tectonic earthquakes. The volcano continues to generate an ash plume, which is drifting to the west.
An attempt was made today to carry out a boat co-spec survey of the plume to discover its gas content. This was unsuccessful but a strong hydrogen-sulphide smell was observed from the boat south of Bransby point.
Average dust levels for today were raised in Salem and Old Towne and low in St Johns and Woodlands.
Residents should continue listening to Radio Montserrat in case there are more sudden developments in the state of the volcano.
