The volcano has been slightly more active overnight than throughout yesterday, with a recurrence of a volcano-tectonic earthquake swarm between approximately 6.00 pm last night and 4.30 am this morning. This swarm was not as intense as some of the swarms experienced over the last few weeks. A few rockfalls were also recorded.
Low level cloud over the volcano has prevented any views of the summit so far this morning. There were no ashfalls reported overnight.
The volcano remains active and potentially dangerous. The lava dome is currently larger than it ever has been before, with a steep eastern face, so further pyroclastic flows are likely. People entering zone C must remain alert, listen to Radio Montserrat and be ready to leave at short notice. Only essential visits should be made. The ash levels in Plymouth are hazardous, and it is very important to wear an ash mask when there is ash in the air.
