Seismic activity at Tongariro remained low overnight. Poor weather has prevented any views of Tongariro since Saturday, but volcanic activity is thought to also have been low.
The weather today is likely to prevent any fieldwork at Tongariro. Once the weather improves additional gas sampling flights and surface gas sampling will be attempted. Data will also be collected from portable seismographs on Tongariro.
An ashfall prediction plot is attached to this bulletin should a future eruption occur.
