In Vanuatu, we use a system of Volcanic Alert Level to define the current status of each volcano. The alert levels range from 0 to 5. The alert levels are used to guide any appropriate response.

   Vanuatu Volcanic Alert Level System
 Title  Level of Alert  Description Area / Distance
 Very Large Eruption


Danger beyond caldera, on entire and surrounding islands and also chance of flank eruption
Moderate Eruption


Danger on volcanic cone, caldera and all island, possibility of very large eruption and also chance of flank eruption

Minor Eruption


Danger within caldera, volcanic cone and other specific area, possibility of moderate eruption and also chance of flank eruption

Major Unrest

2 Danger around the crater rim and specific area, notable/large unrest, considerable possibility of eruption and also chance of flank eruption
Signs of Volcanic Unrest 1  Notable signs of unrest, possible danger near eruptive vents
Normal  0  No signs of change in the activity, limited danger
An eruption may occur at any level and levels may not move in sequence as activity can change rapidly

This system applies to all Vanuatu’s volcanoes.

The Volcanic Alert level is set by the National Geohazards Observatory within Vanuatu Meteorology and Geohazards Department based on the level of volcanic activity.
