Our collegues from Vanuatu reported from your latest Bulletin online (13th
of October 2009), that after the assessment of the geohazards team on Gaua
volcano from 3-7 October 2009, it is confirmed that Mont Garet volcano is
going through an eruptive phase starting from the 27th of September 2009.
Seismic records of the seismic station installed on Gaua show that many
explosions occurred on Gaua volcano. Volcanic gas flux measurements on
October 3rd show that 3000 tons of sulfuric dioxide is released from this
volcano each day, this means that a significant quantity of magma is
degassing from gaua volcano. The lake letas, localised close to the Mont
Garet volcano, is one of the biggest crater lake of South Pacific, its
volume reachs 800 million cubic meters which is drained out through the
river of the Waterfall.

With this information, the Alert level of this volcano is now raised to
Level 2 on the Vanuatu Volcano Alert Level (VVAL). This means that this
volcano is going through a minor eruption. It is not recommended to
approach the volcano. The danger remains in the red zone area on the hazard
map including all the river outlets in Gaua, especially the river of
waterfall. With the related alert level, a level of response from the
community is required. Geohazards is doing its best with the limited
resources available to continue monitoring this volcano.
