Volcanic activity remained at a low level today. There are still 12 hourly cycles in the seismicity, with most rockfalls occurring near the peaks of these cycles. Between 16:00 yesterday and 16:00 today there were 10 hybrid earthquakes, 39 rockfall signals, 3 long-period and 3 volcano-tectonic earthquakes.
An electronic distance measurement was made today between Windy Hill and a new reflector on the crater rim above Farrell's plain. When this measurement has been made several times it will show whether the northern wall of the crater is moving - and so help in predicting whether a collapse like that on Boxing Day is likely on this side of the volcano. The long occupation GPS survey started yesterday between Harris Lookout and Dagenham was completed this morning and a second occupation started between Harris Lookout and Drummond's.
Dust levels at the monitoring stations in houses in Woodlands, St. Peters and Mongo Hill were low again today. Levels were also low at the Catholic Primary School.
People should remain alert and listen to Radio Montserrat for further information.
