Activity at the volcano has been at a slightly higher level than yesterday. Several small to moderate sized rockfall signals were recorded; these increased in number and size overnight. A few volcano-tectonic events which occurred during the period 23:40 on 19 October to 00:50 on 20 October, were also recorded by the seismic network. Tremor levels on the Gages seismic stations has been intermittent for most of the night with one period of continuous tremor between 23:02 last night and 23:25 today, immediately following the heavy rainfall experienced overnight.
The top of the volcano was obscured by low cloud during the night and early morning so no views of the crater area has been possible.
The volcano remains in a highly dangerous condition. The October 1 dome continues to grow at a high rate, and further pyroclastic flows are likely. All residents of Montserrat are urged to exercise caution while visiting the evacuated zone and to become familiar with the new alert system and evacuation procedures. The Tar River and Long Ground areas are extremely dangerous, and people entering these areas face a high risk of death.
