Daily Report
Report for the period 6 pm 2 March
to 6 pm 3 March 1998

The level of volcanic activity over the last twenty four hours has been low.

Seismicity has been lower than the past few days. Between 16:00 yesterday and 16:00 today, 5 hybrid earthquakes, 1 long period earthquake and 25 rockfall signals were recorded on the seismic network. Rockfall activity was scattered throughout the day with no clear peaks.

Some thermocouple measurements were made of the Trant's lobe of the September 21st pyroclastic flow. These yielded a temperature of 111? C at a depth of 110cm measured 100m from the edge of the flow. Samples were also collected for density measurements.

An EDM survey of the line from Windy Hill to the Peak B reflector suggests that the apparent shortening trend of this line is continuing. Since the 25th of January this line has shortened by 6cm.

Dust levels at all monitoring sites were low today.

Residents are reminded to remain alert and listen to ZJB radio.
