Daily Report
Report for the period 16:00 on 12 October
to 16:00 on 13 October 1995


There were nine (9) located earthquakes during the period under review. These were generally of a shallow depth (2-6km) and were all volcano-tectonic events. The earthquakes were scattered mainly beneath the Soufriere Hills and the Long Ground-Tar River area.

There were two episodes of broadband tremor, one was approximately thirty-five minutes long and the other about ten minutes long. These are most probably attributed to increased steam emission.

Despite the very poor visibility, some visual observations were made of the crater area. There appears to have been no significant change in conditions in the crater.

EDM measurements made today at Farrells, Windy Hill, Amersham and Chances Peak do not show any changes from previous occupations. Results from occupation of the Brodericks dry tilt station completed yesterday reveal that there has been no change in tilt at this site. Electronic tiltmeter signals from the Long Ground and Spring Hill site continue to indicate no deformation.
