Scientists have increased their monitoring of the volcano. Gas samplings of springs and fumaroles confirm that volcanic gases above normal levels are present.
A GPS instrument has been installed to detect possible ground movement. The alert level remains unchanged at 1 (out of 4).

Mount Tongariro is a volcanic complex north of Mount Ngauruhoe. It consists of numerous craters, cones and lava flows.

Ash eruptions from Tongariro are recorded from 1855 to 1897, as well as unconfirmed activity in 1926-27.
