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


The volcano was more active today with ash falling all over the island both last night and today. There were two periods of continuous rockfall and pyroclastic flow signals, between 3 and 4 this morning and between 2 and 3 this afternoon. Both of these periods of heightened activity were accompanied by heavy ashfall but ash kept falling more or less all day as a result of ash venting and unfavourable wind direction. Between 16:00 yesterday and 16:00 today there were 9 hybrid earthquakes, 10 long period earthquakes and 168 distinct rockfall signals. The rockfalls are assumed to have originated on the dome above Galways but visibility has been very poor all day and it was not possible to make any observations.

Dust levels at both Woodlands monitoring stations were very high today. Levels at St Peter's and St John's were raised. At these dust levels it is recommended that ash masks be worn outside or in ashy conditions.

People should remain alert and listen to Radio Montserrat for further information.
