The seismic network recorded 3 volcano-tectonic events, 2 rockfalls and 1 hybrid earthquake.
The recorded sulphur dioxide (SO2) flux rate for the reporting period ranged from a maximum of 1202 tonnes per day (t/d) on 3 February to a minimum of 494 t/d on 4 February. The average flux rate for the period was 881 t/d. This figure is above the long term average for the eruption which stands at 550 t/d.
Fumarolic activity continues and has been very similar to that of the last reporting period although the Gage's fumarole has been mostly obscured by cloud, so observations and thermal images of this feature have not been possible.
The pause in dome growth continues but a possibility of collapse or explosion remains, however as the system cools without the introduction of fresh magma and the pause continues the likelihood of this is believed to decrease.
During periods of heavy precipitation it must be remembered the potential hazard from lahar (mudflow) in the drainage channels around the volcano remains.
The alert level remained at 4.
