Seismic activity this week has been very high, with one thousand two hundred and twenty four rockfall signals, three hundred and eighty two long period events and one volcano tectonic earthquake.

Pyroclastic flows have occurred in all the major valleys that drain the volcano except the Tar River valley. Initial pyroclastic flow activity on October 9 and 10 was concentrated to the south. Starting on October 11 pyroclastic flows began travelling down the Tyers Ghaut and peaked on October 13 with a brief small collapse with flows reaching as far as Dyers village just over 2 km from the lava dome. Pyroclastic flows have reached ~ 3 km in the White River to the south; 1.5 km in the Gages valley to the west; and 3 km to the north east down Tuitts and Whites Bottom Ghaut.

The fact that there has been little preferential direction of pyroclastic flows indicates that lava dome growth is focused at the summit of the volcano. Brief views have confirmed considerable growth of the lava dome with the summit approximately 60 metres above the old dome structure.

Due to the extensive ashfall on the western side of the volcano there have been no gas measurements possible this week.

Heavy rainfall caused mudflows (lahars) in the Belham valley on October 14.

The Hazard Level is 3. There is no access to Zone C.
