Science Alert Bulletin RUA-07/06 - Seismic activity at Ruapehu: Science Alert Level remains at 2

A volcanic earthquake was recorded on Saturday night, September 29 at 11:05 pm. The earthquake lasted around 3 minutes and was significantly smaller than the one associated with Tuesday’s eruption. Similar to Tuesday, two periods of weak volcanic tremor of 5 - 10 minutes duration have followed the earthquake recorded last night. This is the first significant seismic activity to be recorded at Mount Ruapehu since Tuesday’s eruption.

We advise people to follow Department of Conservation guidelines for access to the mountain.

The Alert Level remains at 2 (minor eruptive activity) and will be re-assessed on a daily basis.
