The level of activity at the Soufriere Hills volcano during the night has been about the same as that observed during the past several days. Also, its nature has not changed. It continues to be dominated by small- to moderate-sized rockfalls from the flanks of the growing lava dome. Some of these rockfalls were large enough to develop into small pyroclastic flows. Two small volcano-tectonic earthquakes and several small hybrid earthquakes were also recorded. A few episodes of intermittent low-amplitude broadband tremor were also recorded at the stations closest to the Crater throughout the update period.
Visibility was very poor during the early morning from both Bramble Airport and the Observatory.
Extreme care should still be exercised when driving in areas affected by recent ashfalls.
Further rockfalls and pyroclastic flows will occur but all indications at the moment are that these will be confined to the Tar River Valley area. These will obviously be associated with ash clouds which will be blown on the wind, with areas affected by ashfall being determined by the wind direction and strength at that time. The Tar River Valley is extremely hazardous and should not be entered under any circumstances.
