Nine (9) earthquakes were located during the period under review. The events were scattered in southern Montserrat with clusters beneath St. George's Hill and Gages. The events were mainly volcano-tectonic. Focal depths ranged from 0-3km. There were several periods of broadband tremor and three long period events.
Three eruption signals were recorded at 17:25 on the 4/11/95 and 01:39 and 13:07 on the 5/11/95. The first eruption produced an ash plume which rose to around 2500 metres and then descended on the Amersham-Plymouth area and areas to the south of Plymouth. Several millimetres of ash was recorded over the area affected. The second event was seen from the Observatory but no reports of ashfall were received. The third event was a minor eruption which did not produce neither observable ash nor steam.
One mudflow signal was recorded starting at 02:14 this morning (5/11/95). This flowed down Fort Ghaut.
The Tar River EDM line was re-measured today. No change was recorded.
Thick low level cloud cover prevented any visual observations of English Crater from Chances Mt. today.
Dr. S. Arafin of the Seismic Research Unit joined the scientific team on Saturday.
