Montserrat Volcano Observatory


Morning Update
0700H 7 December, 1995


The level of activity has increased again since 18:00 yesterday, although it is still at a lower level than the peak of activity on 05 Dec. Low levels of tremor continue to be recorded at most of the seismograph stations, and the small frequent earthquakes are continuing at a rate of about three per minute. Most of these earthquakes are only recorded at the Gages and Long Ground stations. The pattern of activity indicates that dome growth is continuing.

An earthquake measuring magnitude 3.8 was recorded at 06:28 this morning. It is located approximately sixty miles north of Montserrat and was reported felt by the airport control tower in Antigua.

Observations made yesterday from the Long Ground area indicated that the spine that was first sighted on 03 Dec is continuing to grow, and it is becoming increasingly unstable. The Bramble airport control tower reported this morning that part of the spine appears to have collapsed. If further collapses occur, there is a strong chance that material could flow down the Tar River. Therefore, the areas on the eastern sides of the volcano, that is the Tar River beyond White's Yard, remain extremely dangerous. Scientists very strongly advise members of the public not to enter these areas at the present time.
