AMBAE VOLCANO
15°24’0”S 167°50’0”E Summit 4908ft (1496m)
Current Vanuatu Volcano Alert Level: Level 2

The volcanic activity on Ambae continues in the major unrest state. The Ambae Volcanic Alert Level remains at Level 2.

Major volcanic unrest at Ambae continues and remains confined to Lake Voui. New field observations and data analysis have confirmed that the conditions of Ambae volcanic activity remains unstable and suggest that its activity is likely to continue at a similar level, consistent with volcanic alert level 2. The volcanic hazards danger zone remains limited to a 2 km radius from active vents.

New satellite images from the past few days have shown evidence of continued volcanic degassing. Analysis of seismic data has confirmed the ongoing major volcanic unrest activity on Ambae.

The Ambae volcanic alert level has been at Level 2 since 27th December 2021. Observations of the current activity are consistent with the Volcanic Alert Level 2. Level 2 indicates “Major unrest, with a volcanic hazards danger zone of 2 km radius from active volcanic vents”. With this current volcanic activity, it is a useful reminder that eruptions can occur with little or no warnings.

All tourism agencies, local authorities, people on Ambae and the general public are strongly reminded that the volcanic hazards danger zone at the summit area remains at the Danger Zone A (See Ambae caldera safety map below) which is approximately about 2 km radius from active vents. This area is hazardous due to the gases and others volcanic activity related risk. Acid rain can be expected at the summit area and villages specially those exposed to prevailing trade winds when the volcanic cloud reaches a few kilometers in height. Danger is also present in areas of flowing creeks during heavy rain due to the presence of remaining volcanic ash from 2017 and 2018 eruption at the summit areas. Villages located near flowing creeks can continually expect changes in stream behavior and larger than normal flow rates during heavy rains. People on Ambae Island need to be aware of the dangerous flows while approaching these creeks during heavy rains..
