Montserrat Volcano Observatory

Daily Report
Report for the period 5 p.m. 17 July
to 5 p.m. 18 July 1998

Volcanic activity has remained at a low level during the past 24 hours. 9 rockfall signals, 3 volcano-tectonic earthquakes and 1 long period earthquake were recorded by the seismic stations.

The results of today's COSPEC measurements indicate a sulphur dioxide flux of 1080 tonnes per day. This is about the same level as yesterday.

Ash levels were low at all stations today.

Residents should continue listening to Radio Montserrat in case there are sudden developments in the state of the volcano.

Today is the third anniversary of the start of the current eruption of the Soufriere Hills volcano. In the three years since the first ash emissions, the volcano has erupted nearly 300 million cubic metres of new rock. There have been 90 magmatic explosive events and innumerable pyroclastic flows. The staff of MVO would like to thank all the people who have worked at the observatory for their hard work, often during difficult conditions. We would also like to thank all members of the public who have helped us in carrying out our monitoring operations. We hope that we will be able to continue to provide the best possible volcano monitoring capability for the people of Montserrat.
