Daily Report
Report for the period 6pm 3 May
to 6pm 4 May 1998

The level of volcanic activity over the past 24 hours has remained low.

Between 4pm yesterday and 4pm today there were 10 rockfall signals and 2 volcano-tectonic earthquakes. Most of the rockfalls were small apart from one event at 1024 this morning. This event generated a small ash cloud, observed drifting to the east, and also may have been associated with a pulse of ash venting. The volcano-tectonic earthquakes were all too small to be located. Smaller earthquakes cannot be located because signal amplitudes are too low to allow accurate picking of arrival times at a sufficient number of seismic stations across the network.

Yesterdays regional earthquake east of Martinique was recorded by the seismic network here on Montserrat. This event was felt on Martinique and corresponded to a magnitude of 4.8 on the Richter scale.

Dust levels at all monitoring stations were 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.
