Daily Report
Report for the period 6pm 8 May
to 6pm 9 May 1998

The level of seismic activity has increased slightly again over the past 24 hours.

Between 4pm yesterday and 4pm today there were 25 volcano-tectonic earthquakes recorded by the seismograph network. The earthquake activity started at around 8pm last night and continued throughout the day. A range of earthquake magnitudes was observed, with the smallest events only recorded on stations closest to the volcano. Located earthquakes were tightly clustered and lie directly below the volcano at depths of 3-4km. This is in keeping with the volcano-tectonic earthquake activity observed since the decline in extrusive activity in mid-March. Several small rockfalls were also recorded.

Dust levels at all monitoring stations remained low today.

Residents are reminded that the volcano remains in an active state, and that they should continue listening to Radio Montserrat in case the present quiet situation at the volcano changes suddenly.
