Montserrat Volcano Observatory


Daily Report
Report for the period 5 p.m. 26 October
to 5 p.m. 27 October 1998


The activity at the volcano has been at a lower level than yesterday. There were 36 rockfall signals, 5 volcano-tectonic and 1 long period earthquake during the 24 hours since 4 p.m. yesterday afternoon.

Clear views of the volcano today allowed angular measurements and photographs of the dome to be taken from Harris. These would be used to help determine the current size of the dome. Observations of the volcano revealed that the spine which was located on the western side of the dome has been removed. This may have resulted from the most recent collapse which occurred early yesterday morning.

Measurements were made of the temperature of pyroclastic deposits in the area of the Farm River in Trants today. The maximum temperature recorded was 239 oC at 2 metres (~7 feet) beneath the surface.

Further measurements of the gas composition of the plume were made today by the team from Cambridge University. Results should be available at a later date.

Residents of Montserrat are advised to keep listening to ZJB Radio Montserrat for information relating to any further developments in the state of the volcano.
