Seismicity continues to be dominated by small, regularly spaced hybrid events which have been occuring at a rate of between 3 and 4 per minute during this period. Amplitudes of these events have been variable but all are too small to locate. The total seismic energy expended by these small events has been slowly increasing over the past few days, peaking at about 07:00 on 28 January; it has decreased thereafter during today. Five different seismic signals were recorded during the period - these are thought to be associated with rock falls. A small regional earthquake was recorded by the network at 19:04 on 27 January; it was located about 120 km from Montserrat and had a magnitude of approximately 3.5.
No EDM measurements were carried out today due to the low cloud and rain over the volcano.
Views of the crater area were obtained late today during a brief clear period. Growth appears to be continuing at both the north and south ends of the new dome, with the clearest changes at the south where growth is in the form of general swelling and subsequent spalling of material into the moat. Steam emissions were at a high level all throughout the day, with most steam coming from the southeastern part of the active area.
