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.
