Daily Report
Report for the period 16:00 on 27 November
to 16:00 on 28 November 1995


Six (6) earthquakes have been located for this period. These earthquakes occurred at depths of 0 to 4 km (0 to 2.5 miles), scattered in the southern half of the island. Very small, frequent earthquakes have been recorded at the Gages seismic station, reaching a peak of 8 per minute. The size of these events, however, is smaller than those recorded previously. These earthquakes were probably due to fluid movement beneath the volcano and further slow dome growth.

Five of the seven EDM lines have been remeasured today. The Tar River line remained stable. The other lines show slight fluctuations which are within the bounds of instrument precision. Low cloud prevented the occupation of the Galway's-Chances Peak and O'Garra's-Chances Peak lines.

GPS measurements taken today show no change from yesterday.

Visual observation of the crater area was attempted both from Chance's Peak and from the air using a small plane. Cloud cover prevented any sightings of the crater area. The sound of rock breaking was noted by the Police team on the crater rim.
