Daily Report
Report for the period 6pm 24 April
to 6pm 25 April 1998

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

Between 4pm yesterday and 4pm today there were 4 rockfall signals, one long-period event and 3 volcano-tectonic earthquakes. One of the rockfalls, at 08.14 a.m., corresponded to a modest pyroclastic flow in the Tar River. This was inspected from the air later in the day.

On the same inspection flight, a descent was made to the springs near the foot of the steps to Chance's Peak where precipitates and a strong sulphurous smell had been reported some days ago. The strong smell appears to be associated with the ash deposits in the vicinity, not the springs themselves, and the temperature of the water in the streams was found to be close to ambient. Water samples were collected and these will be analysed for comparison with samples taken by the Montserrat Water Authority from the same springs over a year ago.

Dust levels at all monitoring stations were low today.

Residents are reminded to keep listening to Radio Montserrat for any further information.
