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 the minor unrest state, consistent with the Volcanic Alert Level 1. Latest data analysis from the monitoring system and observations shows emissions of vapor and gases around the volcanic cone and the Sulphur River. 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/volcanic-hazards 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. <i>For further information, please contact Geohazards Division at the Vanuatu Meteorology and Geohazards Department at This email address is being protected from spambots.

VANUATU VOLCANO ALERT BULLETIN N°5 - AMBAE ACTIVITY
Thursday May 25th 2023
AMBAE VOLCANO 15°24’0”S 167°50’0”E Summit 4908ft (1496m) Current Vanuatu Volcano Alert Level: Level 2
Ambae 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 shows presence of volcanic earthquakes and low to high plumes of steam, gas and ash emissions inside cone of Lake Manaro Vui. From the 5th to 7th of April 2023 (3days and 2 nightd), the volcanic activity had intensified, testified by very high plumes of steam, gas and ash observed with lava glow during the night. The increase in volcanic activity is a result of lava rising from the active vent of the emerge cone flowing into the smaller lake of Manaro Vui. Observations from aerial survey, field observations and satellite data confirmed that there is no water remaining in this small lake. Although that the lava-flow lasted only 3 days, the lava-flow of the small lake of Manaro Vui is slowly cooling and degasage continue and on the active vent. However, the Volcanic Alert Level is maintained at Level 2. With the ongoing volcanic activity and the associated hazards such as recent lava flow, gas remissions and ash fall, the danger zone at the summit remains within the Danger Zone B(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 (eg: remobilization of remaining ash from 2017 and 2018 eruption). 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 remains low, however 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. More information about the volcanic hazards can be found on the website: https://www.vmgd.gov.vu/vmgd/index.php/geohazards/volcano/volcano-info/volcanic-hazards 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 in 2017-2018. 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 Voui) 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, and 2016 leading to the 2017-2018 activity. The Vanuatu Meteorology and Geohazards Department will continue to closely monitor Lombenben volcano activity. More information will be provided when necessary.

With the ongoing activity and the associated hazards, the danger zone at the summit area remains limited inside the Permanent Exclusion Zone at Benbow and Danger Zone A at Marum (See Ambrym caldera safety map below). These danger zones are about 1 km around Benbow and 2 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. Ambrym volcano has remained at Volcanic Alert Level 1 since the 10th of October 2019. The level of risk for visitors accessing areas from the caldera remains low, however given the unpredictable character of volcanoes all tourism agencies, local authorities, people on Ambrym 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/volcanic-hazards 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. The Vanuatu Meteorology and Geohazards Department will continue to closely monitor Benbow and Marum volcano activities and provide information when necessary.
