Daily Report
Report for the period 16:00 on 18 October
to 16:00 on 19 October 1995

Thirty-one (31) earthquakes were located during the period under review. The events were essentially clustered beneath the Soufriere Hills volcano within the depth range 0-4km. The events were all volcano-tectonic events.

Several periods of broadband tremor occurred throughout the period and there was one period of low frequency tremor.

Three eruption signals were recorded by the seismograph network, these occurred at 16:21 and 22:07 on the 18th and at approximately 15:16 on the 19th. The first event was associated with the formation of a new vent within the moat area of English's Crater, located just south west of the July 18th vent. The event which occurred at 15:16 the afternoon, generated a mudflow which descended the Hot River following the same path as the mudflow which occurred two days ago.

Excellent weather conditions once again provided perfect viewing conditions at English's Crater. The helicopter provided an excellent platform to perform overhead observation of the entire crater area on several occasions. The observations made today allowed the scientific team to locate more accurately the areas of activity using both video and stil photography. Aerial observation was also made of the venting activity which took place this afternoon.
