The volcano has been slightly more active during this reporting period. The seismic records have been dominated by small to moderate-sized rockfall and pyroclastic flow signals. The largest of these events overnight was at 6:36 p.m. yesterday. These signals are the results of material falling from the active area of the dome above the Galway's Wall and flowing into the White River valley. There have also been a number of long-period earthquakes. Two regional tectonic earthquakes have also been recorded by the seismic network at 01:59 a.m. and 04:51 a.m. this morning. A preliminary location of the second of these events puts the epicentre to the north-east of Montserrat.
Currently the summit of the volcano is shrouded in cloud but things look promising that this will lift and allow further observations to be made of the dome complex.
Despite the apparent low level of activity, the volcano remains in an unstable state, with further dome growth in the southern region above the Galway's Wall. Another dome collapse with extensive pyroclastic flows in the White River is expected within the next week. Residents of Montserrat should remain alert, and listen to Radio Montserrat for further updates. 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.
