Vanuatu Volcanic Alert Level (VVAL)
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|
|Danger on volcanic cone, caldera and all island, possibility of very large eruption and also chance of flank 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 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. Download PDF here

VANUATU VOLCANO ALERT BULLETIN N°11 – AMBAE ACTIVITY
Saturday September 23rd 2017
15°24’0”S 167°50’0”E Summit 4908ft (1496m)
Current Vanuatu Volcano Alert Level: Level 4
Volcanic activity at Ambae is continuing to increase. The Alert Level for Ambae volcano is raised from Level 3 to Level 4 .
This means that the Ambae volcano is in a moderate eruption state . At this Alert Level, the volcanic activity is likely to continue to increase or decrease to its normal level of unrest at any time. Danger is in the Red, Grey, Orange and White dotted Zones (See map below).
With this situation, flying rocks and volcanic gas will affect the Red Zone which is about 6.5 km radius from Manaro Voui . Villages located in the Grey and Orange Zones will expect unusual volcanic hazards and ash falls can be expected around the island especially in villages exposed to prevailing trade winds direction, White Zone dotted . Acid rain may also be expected in that zone. Acid rain cause foliage fumigation hence damage garden crops.
It’s very important that authorities, communities, villages, visitors and travel agencies seriously consider this information.
The Vanuatu Meteorology and Geohazards Department will continue to closely monitor this volcano activity. More information will be provided as soon as necessary.
