Daily Report
Report for the period 16:00 on 9 March 1996
to 16:00 on 10 March 1996

Seismic activity has been low over the last 24 hours. Twelve long-period earthquakes were recorded by most of the stations in the network, along with several signals generated by rockfalls on the dome.

The eastern EDM triangle between Castle Peak, Long Ground and Whites was measured this afternoon. The line lengths have changed only slightly since the triangle was last measured on Thursday. These changes continue the long-term movement of Castle Peak of about 2 mm per day.

Visual observations were made from the helicopter this morning, in cloudy conditions. No rockfalls were observed, but vigorous steaming continues. A lot of Sulphur Dioxide was being produced from the south of the dome.

Drs Peter Baxter and Andrew Allen arrived on Montserrat this afternoon. They are visiting for 10 days to study the gas and particluate content of the steam plume and to advise the Government on possible effects on human health.
