The volcano has remained slightly more seismically active today. There was a swarm of volcano-tectonic and hybrid earthquakes between 10 and 12 this morning - which coincided with a time of increased rockfall activity. There were also rockfalls and earthquakes of both types recorded throughout the day. Between 16:00 yesterday and 16:00 today there were 27 hybrid earthquakes, 14 long period earthquakes, 36 volcano-tectonic earthquakes and 91 distinct rockfall signals.
The volcano was clear for much of the day and vigorous steam plumes were again seen coming from the new dome which now fills the December 26th collapse scar. It was observed from Jack Boy Hill that this steam and ash venting was occurring largely above Tuitt's Ghaut. Most rockfall activity was again on the Galways side of the dome.
Dust levels at all monitoring sites remained low today.
People should remain alert and listen to Radio Montserrat for further information.
