Tongariro volcano update 8: 1627hrs 9 August 2012
The Volcanic Alert Level stays at Level 2. The Aviation Colour Code remains Yellow. This recognises that activity is low level but renewed unrest is possible.

GNS Science and Department of Conservation scientists continue to monitor the mountain closely and are in contact with civil defence emergency management agencies and emergency services. Authorities will issue new information as soon as possible if the situation changes.

Ashfall collected on Tuesday from various locations around the volcano have been analysed for fluorine content by Massey and Canterbury Universities. These results show that moderate levels of fluorine are present, but due to the restricted distribution of the ash, this currently poses no current human-health or agricultural threat beyond the immediate vicinity of the volcano. Enquiries about the fluorine analyses can be answered by Professor Shane Cronin of Volcanic Risk Solutions or Professor Mike Hedley of the Fertiliser and Lime Research Centre at Massey University.

Initial microscopic analysis of the ash also shows that there is very little or no new magma. This suggests that the eruption was predominantly steam driven, but the involvement of magma in the future cannot be ruled out.
