Daily Report
Report for the period 5 p.m. 7 October
to 5 p.m. 8 October 1998


The Soufriere Hills volcano has remained quiet over the past twenty-four hours. A total of 11 rockfalls and 3 volcano-tectonic earthquakes were recorded on the broadband seismic network. Between 2200 and 0000 last night, there was a period of increased volcanic tremor. The tremor was similar in character to that observed on the 29th of last month, which was observed to correspond to a period of vigorous ash venting from the Northern flanks of the dome.

GPS measurements are being recorded overnight at Whites and Windy Hill as part of the continuing ground deformation program. In addition, some dome surveying was carried out from Whites using the theodolite.

The broadband seismic network is now back to full strength after equipment was taken in from the field to safeguard it during the passage of Hurricane Georges.

Residents of Montserrat should continue to check Radio ZJB in case of sudden developments in the state of the volcano.
