Tongariro volcano news & activity updates

false reports of ash venting

Sunday Sep 23, 2012 10:05 AM | AUTEUR : T

GeoNet reported on 20 Sep, that "No further volcanic activity has occurred from the reactivated Upper Te Maari craters on Tongariro. Scientific teams have been busy collecting and analysing data to understand the current unrest.

Seismic activity has also remained low over the six weeks since the eruption, however, some small earthquakes have been recorded near Te Maari."

Reports of ash emissions on Friday were discredited by GeoNet who concluded that the observers (pilots) confused aerosols in the steam and gas plume with ash.
