Today seismic activity has remained at a similar level to yesterday with small hybrid earthquakes and rockfall signals recorded. Visibility today was poor.
Between 16:00 yesterday and 16:00 today there were 10 long-period earthquakes, 131 hybrid earthquakes, and 38 rockfall signals. The hybrids remained very small - in fact many of the hybrids observed on the drums did not trigger the networks and so are not included in the count. This explains the difference in the count compared to yesterday when the activity was, in fact, very similar.
It has to be assumed that the dome is continuing to grow. This means that pyroclastic flows could occur down any of the ghauts around the volcano with little warning. The level of ash in the atmosphere in St Peter's and in St John's, as averaged over the last 24 hours, has remained low.
