Activity at the Soufriere Hills Volcano during this period has continued at a slightly lower level to that which was observed during the early parts of yesterday. Seismicity during the period has been dominated by small- to moderate-sized rockfall signals. The largest of these events occurred at 04:42, 08:53, 09:20, 10:32 and 12:43 today. Light ashfalls associated with the largest events affected Plymouth, Amersham, Upper Gages, Richmond Hill and areas to the southwest of the volcano. There was one episode of low amplitude broadband tremor recorded at the Gages seismic station between 03:10 to 08:31. A few small hybrid events continue to be recorded on the Chances Peak station.
Attempts were made today to occupy the Eastern EDM triangle and the Galways-O'Garra's-Chances Peak triangle. However, low cloud cover obscured the EDM reflectors and prevented any measurements from being made. Measurements were made on the University of Puerto Rico GPS network at Radio Antilles, Harris Lookout and St George's Hill.
COSPEC measurements were made today along the coast road south of Plymouth. The data from this survey is currently being processed.
Visibility has been very poor throughout the entire day and no views were obtained of the dome.
Residents of the areas affected by the ashfalls of yesterday are again advised to wear dust masks when outside or when cleaning up ash inside. Drivers are urged to beware of the potentially hazardous driving conditions due to ash on the roads and should drive with caution.
The present level of activity at the Soufriere Hills Volcano continues to cause concern to the scientists. The MVO urges that visits to the evacuated zone are kept to a minimum. The Tar River, Long Ground and Whites areas are extremely dangerous and should not be entered under any circumstances.
