Four locateable volcano-tectonic earthquakes occurred overnight at St. George's Hill, South Soufriere Hill and near Long Ground, from depths of 2 to 5 km. These earthquakes continue the trend seen since 10 December, with low levels of seismicity and earthquakes scattered across the south of the island. Eight long-period earthquakes were also recorded by most of the seismic stations. The Gages seismic station is still recording some small long-period earthquakes, but these are less common than they were yesterday.
Visual observations of the crater were made from the helicopter at dusk last night. It was confirmed that the top of the large spine has broken off. This spine has been growing since December 17. The two smaller spines along side this spine are still intact. Glowing rock was again observed in crater, especially at the south-western side, near the September spine. This area of the crater may be becoming more active. Scientists have been at Whites since about 05:00 this morning, but so far low cloud has prevented any good observations of the crater area.
