Following yesterday's pyroclastic flows, the level of rockfall activity recorded by the seismic network decreased overnight. At 3:20 am, a shallow earthquake swarm began which is still ongoing. The first few earthquakes were small, but at around 5 am several larger earthquakes were recorded, with magnitudes similar to the largest earthquakes in previous swarms.
The visibility is not very good this morning, but some views of the crater should be possible during the day, which will allow the scientists to assess the state of the dome following yesterday's pyroclastic flows.
The volcano remains in an unstable state, and residents of Montserrat should remain alert, and listen to Radio Montserrat for further updates. Further dome collapses could start at any time. Ash masks should be worn in ashy environments. Visits to zone C should be restricted to those that are essential. All of Zone A, which includes Long Ground and St Patrick's, is very dangerous and should not be entered under any circumstances.
