Daily Report
Report for the period 6 pm 25 February
to 6 pm 26 February 1998

Volcanic activity over the last 24 hours has been dominated by an increase in the number of recorded earthquakes. Earthquakes have been recorded almost continuously throughout the day, with a corresponding reduction in rockfall activity.

The first earthquake swarm occurred between 1930 and 2016 yesterday evening and consisted of 19 volcano-tectonic earthquakes and 2 hybrid earthquakes. The second swarm began at 0136 last night and continued throughout the day until 1528. This swarm contained a mixture of 33 volcano-tectonic earthquakes and 82 hybrid earthquakes. Only five of these events were locatable, giving depths of between 2 and 3km. The number of rockfalls has been low and have been scattered through the day rather than concentrated in a period of continuous activity as on the previous days .

Some clear views of the volcano today showed the continued ash venting from the area of new growth.

The solar eclipse between 1300-1600 had no apparent effect on the volcanic activity.

Dust levels at all monitoring sites were again low today.

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