Daily Report
Report for the period 6 pm 1 March
to 6 pm 2 March 1998


Volcanic activity during the past twenty four hours was low. Dust levels at most monitoring sites were also low.

Seismicity has been dominated by rockfall signals and hybrid earthquakes. Between 16:00 yesterday and 16:00 today, 29 hybrid earthquakes, 1 volcano-tectonic earthquake, 1 long period earthquake and 34 rockfall signals were recorded on the seismic network. Rockfall activity was scattered throughout the day with no clear peaks. Several signals were recorded which have been associated with pyroclastic flows in the past; none of these flows were observed. The largest of these signals occurred at 8:36 pm last night.

A continuous GPS station was re-established at Whites today. This replaces the station which was damaged by volcanic activity last year and is another collaborative effort between the MVO and the University of Puerto Rico.

Dust levels at all monitoring sites were low today except for one site in Woodlands which was raised..

Dr Keith Rowley and Dr Ricky Herd arrived on island yesterday. Dr Rowley would take over as Chief Scientist from Mr Richard Robertson who returns to the Seismic Research Unit tomorrow. Mr Wilkie Balgobin of the Seismic Research Unit also arrived on island today for another month long tour of duty at the MVO.

Residents are reminded to remain alert and listen to ZJB radio.
