Montserrat Volcano Observatory
Montserrat, W.I.

Report for the period 5 p.m. 4 December to 5 p.m. 5 December 1998

In the last 24 hours the seismic networks recorded 20 rockfall signals
and 66 volcano-tectonic earthquakes. Most the volcano-tectonic
earthquakes occurred in a swarm overnight. Several short periods of
volcanic tremor were also recorded; this commonly coincided with light
ash production. 

A field team went to the Trant's areas yesterday afternoon, and made
measurements in the pyroclastic flow deposits. Several of the usual
sites for temperature measurements have now been impacted by mudflows,
but at one site, where temperatures were last measured in September this
year, the deposits were still at 95 degrees centigrade at 75 cm depth.
The Farm River is now in a new gully up to 3 m deep, and the main
channel is directed to the north of W.H. Bramble airport towards Trant's
Yard. 

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.
