Current Vanuatu Volcano Alert Level: Level 2
Following the assessment done by the Geohazards team on the 07th and 08th July 2010, Yasur vol-
cano has maintained its high activity with strong degassing and ash emissions from all the three active
vents. The ash falls are especially over the western part of the island. Fresh volcanic bombs have fall-
en around the crater rim. Some explosions could be heard and viewed from the villages. The local pop-
ulation has confirmed that this significant activity has been consistent since the beginning of the year.
The OMI pictures and the seismic data collected from the monitoring stations on the island confirm this
significant activity with the the current strong degassing and explosive activity which is still on going.
Under these circumstances, the Alert Level for Yasur volcano is maintained at LEVEL 2 according
to the Vanuatu Volcanoes Alert Levels (VVAL). This means that the Yasur volcano is going through
moderate activity and the danger remains close to the volcano, within the Red Zone of the hazard map.
Volcanic ash falls could follow the direction of the wind and they are expected in the yellow zone of the
hazard map. (fig.1).
Visitors are strongly advised to keep out from the volcano crater rim and to respect the security mea-
sures in place (security ribbon).
Close monitoring of this volcano will continue . The next bulletin will be issued as appropriate.
