Daily Report
Report for the period 16:00 on 13 Jan. 1996
to 16:00 on 14 Jan. 1996

Seismic activity continued at a relatively high rate until 08:00 this morning, although the frequency of occurrence of events was lower and the amplitude smaller than over the previous 24 hour period. On average, the seismic network recorded one of these hybrid events every two to five minutes, with additional, small long-period events also occurring. After 08:00, the repetitive hybrid events decreased considerably, although short periods of low amplitude, broadband tremor were recorded on the Gages seismometer; some of these were accompanied by emissions of small amounts of ash. Events from yesterday are still being located; todays hybrid events will be too small to locate individually, although they are likely to be occurring at a high level beneath the crater area.

EDM measurements were made today on the White's Yard - Long Ground - Castle Peak triangle and on the Gages Wall - Dagenham - Amersham triangle. No significant change within the errors of the technique was noted from previous occupations for both of these triangles.

Visual observations were made from the helicopter and from the crater rim at Chance's Peak during the day. The large spine which appeared several days ago collapsed some time in the past 2 days, but the base of the spine appears still to be growing and there is some new material in the area around the September spine, which itself has partially collapsed. A number of small ash eruptions were generated by rock falls from the area of active dome growth.

Todays soccer match between MVO Allstars and Police was a hard-fought affair, with the score at full time being 3 - 3. Penalty kicks were then taken, with MVO Allstars coming out on top by 5 penalties to 4.
