VANUA LAVA VOLCANO 
13°80’S 167°47’E Summit 3021ft (921m)
Current Vanuatu Volcano Alert Level: Level 1

 

Vanua Lava volcano is continuing in the minor unrest state. The Volcanic Alert Level remains at Level 1.

Mt. Suretamatai volcanic activity is continuing at a minor unrest state, consistent with the Volcanic Alert Level 1. Latest satellite data shows no major emissions of volcanic plume but steam around the volcanic cone and the Sulphur River continue to be observed locally. However, the Volcanic Alert Level is maintained at Level 1.

With the ongoing activity and the associated volcanic hazards, the danger zone is limited around the volcano cone and the Sulphur River.
It is a useful reminder that eruptions can occur at any level of unrest with little or no warnings. 

Mt. Suretamatai has remained at Volcano Alert Level 1 since the 27th of May 2016. At this alert level, the risk for visitors accessing areas from the volcano cone and Sulphur River remains low, however given the unpredictable character of volcanoes all tourism agencies, local authorities, people of Vanua Lava and the general public are advised to give serious consideration to potential volcanic hazards. 

More information about the volcanic hazards can be found on the website: https://www.vmgd.gov.vu/vmgd/index.php/geohazards/volcano/volcano-info/resources

Vanua Lava volcano is one of the active volcanoes in Vanuatu and in contrast to other large volcanoes in the country, it does not contain a youthful summit caldera. A chain of small stratovolcanoes, oriented along an NNE-SSW line, gives the low-angle volcano an irregular profile. Historically, this volcano had low infrequent activity except in XIX (19) century with 3 moderate manifestations and in XX (20) century with 2. 

The Department of Meteorology and Geo-hazards will continue to closely monitor Vanua Lava volcano activity and provide information when necessary.

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

 

Manaro Vui volcano is continuing in the major unrest state. The Volcanic Alert Level remains at Level 2

Manaro Vui volcanic activity is continuing in the major level of unrest, consistent with the Volcanic Alert
Level 2. Latest data analysis from the monitoring system confirmed ongoing steam and gas emissions on
the active vent inside the Lake Manaro Vui. The Volcanic Alert level remain at Level 2.

With the ongoing volcanic activity and the associated hazards such as lava flow, gas emissions and ash fall, the danger zone at the summit remains at the Danger Zone A (See Ambae caldera safety map below) which is about 2 km radius from the active vent. A reminder on persistent threat within areas of flowing creeks during heavy rain (e.g., remobilization of ash and debris). 
It is a useful reminder that eruptions can occur at any level of unrest with little or no warnings. 

Manaro Vui volcano has remained at Volcanic Alert Level 2 since the 27th of December 2021. At this alert level, the risk for visitors accessing areas from the crater lakes and the caldera is LOW. Given the unpredictable character of volcanoes all tourism agencies, local authorities, people on Ambae and the general public are advised to give serious consideration to potential volcanic hazards as well as the danger zone limit. 

More information about the volcanic hazards and the Ambae volcano key messages can be found on the website: http://www.vmgd.gov.vu/vmgd/index.php/geohazards/volcano/volcano-info/resources

Manaro Vui volcano is a very large volcano and is frequently active. A large-scale eruption about 400 years ago built a volcanic cone in the summit crater and that crater is now filled by Lake Voui; however, the modern active vent area is now within the volcanic cone that grew and remained since December 2021. Historic activity is poorly known, but there is documented activity in 1530, 1670, 1870, 1915 and 1966. All documented activity has been from the summit crater (Lake Vui) except for the 1670 activity, which included a flank eruption producing lava flows at Ndui Ndui. The 2017-2018 eruption episode started in 1991, with eruptions in 1995, 2005, 2016 leading to the 2017-2018 activity. The latest episodes of major unrest began in 2021 when the active cone built up exposing the vent from the lake water. Hence, Manaro Vui is considered an open vent volcano with the last increased activity in January 2023 producing a lava flow to the north of the active cone. 

The Vanuatu Meteorology and Geohazards Department will continue to closely monitor Manaro Vui volcano activity. More information will be provided when necessary.

Current Vanuatu Volcano Alert Level: Level 2

 

Ambrym volcano activity is continuing in the major unrest state. The Volcanic Alert Level remains at Level 2.

Ambrym volcano activity is continuing in the major level of unrest, consistent with the Volcanic Alert Level 2. Latest seismic analysis and observation confirmed ongoing steam emissions from the active craters of Ambrym volcano. Earlier this month, the Benbow crater underwent a short lived (4 days) eruption producing lava flow within the Benbow crater.

With the ongoing activity and the associated hazards, the danger zone at the summit is maintained at Danger Zone B (See Ambrym caldera safety map below). These danger zones are about 2 km around Benbow and 4 km around Marum craters including Maben-Mbwelesu, Niri-Mbwelesu and Mbwelesu. Additional danger zone is at the South-East of Ambrym within 500 meters from major cracks (Opened during the 2018 Eruption). 
It is a useful reminder that eruptions can occur at any level of unrest with little or no warnings.

The level of risk for visitors accessing areas from the caldera is high. People on Ambrym especially, villages close to the volcano are expected to experience acid rain and are advised to follow the Ambrym key messages for volcanic ash, gas and acid rain, to protect water supply sources.

More information about the volcanic hazards can be found on the website:

Ambrym volcano is a very active volcano in Vanuatu with large caldera of 12 km in diameter and 2 active craters, Marum and Benbow. The volcano has been active during historical time at both summit and flank vents, producing moderate explosive eruptions and lava flows that have reached the coast. The larger events include eruptions in 1820, 1894, 1913 or 1929. Over the last seventy years (before the 2018 eruption), there have been no eruptions that extended beyond the summit caldera. The eruption of 1988 and 2015 are focused in the caldera. The December 2018 eruption was focused in the summit caldera, and also affected the Eastern Fracture or Rift Zone with ground deformation, rifting, faulting and uplift, but no eruption occurred there. On 25th January 2022, and again on 13th January 2024, there was a minor eruption inside Benbow crater spewing lava flows.

The Vanuatu Meteorology and Geohazards Department will continue to closely monitor Benbow and Marum volcano activities and provide information when necessary.

Yasur volcano is continuing in the major unrest state. The Volcanic Alert Level remains at Level 2.

The Yasur volcanic activity is continuing at the major unrest state, consistent with the Volcanic Alert Level 2. Latest satellite data shows an increase in emissions of steam, gas, and ash on the crater. Some explosions remain intensified causing volcanic projectiles or bombs that fall in and/or around the summit crater. Ground observation reported landslide inside the crater vent. With this activity, some villages surrounding the volcano will continue to expect ash fall impacts and/or acid rain depending on wind speed and direction and weather. The Volcanic Alert Level is maintained at Level 2. 

With the ongoing volcanic activity and the associated hazards such as gas plumes, ash fall, possible landslides and volcanic projectiles or bombs to fall in and/or around the summit crater, the danger zone is limited in the danger zone A (red circle) which is 600 meters from the Permanent Exclusion Zone (See Yasur caldera safety map below). It is a useful reminder that eruptions can occur at any level of unrest with little or no warnings. 

Yasur Volcano has remained at Volcanic Alert level 2 since the 28th of October 2016. At this alert level, the risk for visitors accessing areas from the crater rim to the parking area is INTERMIDIATE. Given the unpredictable character of volcano all tourism agencies, local authorities, people on Tanna Island and the general public are advised to give serious consideration to potential volcanic hazards. .

More information about the volcanic hazards can be found on the website: https://www.vmgd.gov.vu/vmgd/index.php/geohazards/volcano/volcano-info/resources

Yasur is well known and most frequently visited of the Vanuatu volcanoes. It has been in more-or-less continuous Strombolian activity since Captain Cook observed ash eruptions in 1774. This type of activity may have continued since ages. The active cone is largely contained within the small Yenkahe caldera, and is one of the youngest Holocene’s volcanoes (11 700 years to present) of Vanuatu. 

The Vanuatu Meteorology and Geohazards Department will continue to closely monitor Yasur volcano activities and provide more information when necessary.
