Flemmings, Montserrat --- 7 Jan. 2007 --The remains at 4. There have
been no major changes in activity levels during the last 48 hours.
Ongoing pyroclastic
activity has been observed on the NW sector of the volcano with pyroclastic
flows in Tyres Ghaut and Gages
Valley. Run out distances
in Tyres Ghaut have, however, shown signs of increasing, possibly exceeding the
previous maximum estimate of 1500 m.

Low level gas and ash
venting from a vent on the western side of the dome is ongoing. Fortunately the
prevailing wind direction remains E-W and the occupied areas of Montserrat have been largely unaffected by ash fall.
Seismic activity remains
relatively low, although there has been a slight increase in the number of
events in the last 24 hours. Nevertheless, the style of activity is unchanged
and remains dominated by rockfall signals and long period earthquakes, accepted
as resulting from either surface or shallow (1-2 km) activity.
