Activity at the volcano has increased slightly overnight. Another two moderate long-period earthquakes have been recorded. These are thought to be due to small explosions within the dome, and are followed by rockfall signals. Several other small rockfalls have also occurred. There was a small volcano-tectonic earthquake at 00:48 this morning. This earthquake still has to be studied in detail, but it's preliminary location is at over 10 km depth to the east of the island. Earthquakes at this depth have been rare during the last year.
The volcano is still shrouded in cloud, so no views of the crater have been possible.
The volcano is in a highly dangerous condition, as the small explosions recorded during the last 24 hours show. The October 1 dome continues to grow at a relatively fast rate and further pyroclastic flows are likely. These could trigger another explosive eruption with very little warning. The Tar River and Long Ground areas are extremely dangerous, and people entering them face a high risk of death.
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.
