Observations this week show that dome growth is now focused towards the east, with a lava lobe growing in that direction and the majority of rockfall and pyroclastic flow activity occurring in the SE to NE sector. The largest pyroclastic flows have travelled up to 2km down Tar River valley

During the reporting period the seismic network recorded 316 rockfall signals, 230 long period earthquakes, 126 long period - rockfall signals, 12 hybrids and 1 volcano-tectonic earthquake.

Sulphur dioxide fluxes varied between 231 tonnes per day on 27 March and 1168 tonnes per day on 29 March. The average for the reporting period was 523 tonnes per day.
