Seventeen (17) earthquakes were located during the period. Most of these were long-period events and occurred beneath the Soufriere Hills volcano at depths of 0 to 5 km (0 to 3 miles). The level of seismicity has been very low, and the small, frequent long-period events recorded recently have ceased completely. However, two intervals with several large, closely-spaced long-period events occurred. Three large volcano-tectonic earthquakes were recorded; the largest of these was a magnitude 2.5 earthquake at 03:44 this morning which was located at a depth of 3 km beneath the volcano. Several short periods of low amplitude tremor were also recorded.
EDM measurements to Castle Peak were attempted this morning, but could not be completed because of the low cloud levels on the volcano. The Farrell's and Windy Hill lines were measured this afternoon, but the results are not yet available. GPS measurements were again made overnight at stations at Harris' Lookout, Radio Antilles Aerial and St. George's Hill. Results from two days ago show very small changes within the errors of the method. The line from Harris Lookout to St George's Hill was first measured on 06 October; the length of the line has changed by less than 0.5 cm since then.
No visual observations of the crater area were made today due to low cloud cover. Mr Lloyd Lynch departed the island early this morning after a one month period as Chief Scientist at MVO.
