There were a number of small explosive events at Soufriere Hills in Montserrat in the past few days.

The director of the Montserrat Volcano Observatory says there is little concern for heightened activity. The volcano has been erupting off-and-on since 1995 and these eruptions are just part of the ebb-and-flow of this period of activity.
