Bulletin N°9- Vanua Lava Activity

VANUATU VOLCANO ALERT BULLETIN N°9 - VANUA LAVA ACTIVITY
Thursday September 29th 2022

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 level of low unrest. The Volcanic Alert Level remains at Level 1.


The Vanua Lava volcanic activity is continuing at the low unrest level, consistent with the Volcanic Alert Level 1. New scientific analysis suggest that the volcanic activity is likely to continue at this same level of minor unrest. Volcanic hazards remain on the volcanic cone and sulfur river (e.g. volcanic gases). Danger Zone for life safety is limited around the volcanic cone and the sulfur river.

 Latest observations and satellite data confirm that there is no significant manifestation and the volcanic activity conditions remain stable. There is an ongoing presence of volcanic gases around the volcanic cone and around the sulfur river. Gas smell will continue while approaching these two areas.


The Volcanic Alert Level for Vanua Lava volcano has been at the Level 1 since 27th May 2016. The current observations are consistent with the activity of the Volcanic Alert Level 1. Level 1 indicates ‘Minor level of unrest; Danger Zone is near the volcanic area and the sulfur river’ .


Vanua Lava volcano is one of the active volcano 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 a 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.

 All tourism agencies, visitors, local authorities, and people from Vanua Lava Island and general public are reminded that due to the current volcanic activity, the danger zone remains at around the sulfur river and volcano area. In these areas, volcanic gases will always be expected. Visitors may expect impact of this gas while approaching these two areas.


The Vanuatu Meteorology and Geohazards Department will closely monitor this volcano activity.
 More information will be provided accordingly when necessary.

Bulletin N°10- Gaua Activity

VANUATU VOLCANO ALERT BULLETIN N°10 - GAUA ACTIVITY
Thursday September 29th 2022

GAUA VOLCANO 
14°16’0”S 167°30’0”E Summit 2615ft (797m)
Current Vanuatu Volcano Alert Level: Level 2

 

Gaua volcano has now increased in the high level of the major unrest state. The Volcanic Alert Level remains at Level 2.


The Gaua volcano activity has now increased in the high level of the major unrest state, consistent with the Volcanic Alert Level 2. New analyses suggest that this volcano activity is likely to continue at this same level of major unrest (Level 2) or increase to the minor eruption state (Level 3). Volcanic hazards remain on the Gaua volcanic cone (e.g. volcanic gases). The danger zone for life safety is limited on the volcanic cone.

 Ground observations and satellite data confirmed that the current activity consists of ongoing volcanic steam cloud which may contain volcanic gases at Mt. Garet. Visitors will continue to smell volcanic gas while approaching the volcanic cone.

The Volcanic Alert Level (VAL) for Gaua volcano has been at Level 2 since 31st January 2018. The current observations are consistent with the activity of the Volcanic Alert Level 2. Level 2 indicates ‘Major level of unrest ; Danger zone is on the volcanic cone’. With this current volcanic activity, it is a useful reminder that eruptions can occur with little or no warning.

Gaua volcano is one of the active volcano in Vanuatu. Historically, the formation of Mount Garet active cone of and other small cinder cones in the SW part of the caldera has left a crescent-shaped caldera lake, Lake Letas. The symmetrical, flat-topped Mount Garet cone is topped by three active craters.


Advice to all tourism agencies, local authorities, people of Gaua and the general public with this current activity, the danger area remains at the volcanic cone. The level of risk for visitors accessing areas around Mt. Garet is high. Villages exposed to wind direction may expect volcanic gases and/or ash falls impact and other volcanic risk could occur at any time in such major unrest state.


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

Bulletin N°9- Ambae Activity

VANUATU VOLCANO ALERT BULLETIN N°9 - AMBAE ACTIVITY
Thursday September 29th 2022

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

The volcanic activity on Ambae is continuing in the major unrest state, with a lower level of activity, consistent with the Volcanic Alert Level 2. The Ambae Volcanic Alert Level was in Level 2 since 14th December 2021. New analysis suggest that the volcanic activity is likely to pursue in this lower level of activity of major unrest state but could increase to a high level of activity of major unrest state. Volcanic hazards remain at the summit area and creeks (e.g., remobilization of remaining ash from 2017 and 2018 eruption and current activity).

The danger zone for life safety at the summit area remains limited in the Danger Zone A (See Ambae caldera safety map below). This danger zone (Danger Zone A) is about 2 km radius from the 2017-2018 active vents. An additional danger zone is within areas of flowing creeks during heavy rain.
 

Latest seismic and observation data from the monitoring system confirmed the ongoing volcanic activity and the cone built up (at end December 2021) inside Lake Voui remains. The volcano continues to emit volcanic gas and possible ashes that is quasi contained within Lake Vui. These observations of the current activity is consistent with the activity of the Ambae volcano under Volcanic Alert Level 2 indicating ‘Major level of unrest; the Danger area remains at 2 km around the volcanic vents and within the area of flowing creeks. With this current volcanic activity, it is a useful reminder that eruptions can occur at any level of unrest with little or no warnings.

Ambae 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.
 


All tourism agencies, local authorities, people of Ambae and the general public are advised that with the current volcano activity, the danger zone (Danger Zone A) remains at the summit about 2 km radius from the 2017-2018 active vent. In addition, the presence of remaining volcanic ashes elsewhere in the island (deposited during the 2017/18 eruption), can be mobilized by rainfall. The villages located near flowing creeks (dangerous flow zones) can continually expect changes in stream behavior and larger than normal flow rates during heavy rain fall. People of Ambae Island need to be aware of the dangerous water flows while approaching these creeks during heavy rains.

Bulletin N°10- Ambrym Activity

VANUATU VOLCANO ALERT BULLETIN N°10 - AMBRYM ACTIVITY
Thursday September 29th 2022

AMBRYM VOLCANO 
16°15’00”S 168°07’00”E Summit Elevation 4377ft (1334m)
Current Vanuatu Volcano Alert Level: Level 1

 

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

Ambrym volcano is continuing in the minor unrest state. The Volcanic Alert Level remains at Level 1. The volcano activity on Ambrym is continuing in the minor unrest level, consistent with the Volcanic Alert Level 1. Scientific analyses suggest that the Ambrym volcano activity is likely to continue at this level of minor unrest. Volcanic hazards remain at the summit craters area and the South East part of Ambrym Island (e.g., major cracks from 2018).

Latest observations and daily analysis of the Ambrym seismic data from the volcano monitoring system confirm that the Ambrym volcano activity conditions remain at the level of minor unrest. With this current volcanic activity, it is a useful reminder that eruptions can occur at any level of unrest with little or no warning.

The volcanic hazards still present on Ambrym, specifically at the summit and eastern part of the Island. These are related to the presence of cracked areas. In addition to the summit hazards, the presence of active rifts and faults (major ground cracking) at the South-East area of Ambrym are also hazardous, they will continue to be eroded and affected by earthquake activity. The danger zone for life safety 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. An additional danger zone at the South-East of Ambrym remains within 500 meters from major cracks.
 

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.
 


All tourism agencies, local authorities, people of Ambrym and the general public are reminded that due to the current volcano activity and presence of cracked areas at the caldera, the danger zone remains at the Permanent Exclusion Zone at Benbow and the Danger Zone A at Marum which are set about 1 km radius from Benbow and 2 km radius from Marum. There are life safety hazards within these hazard zones. Due to the presence of active rifts and faults at the South-East area of Ambrym, communities concerned are advised not to access within 500 meters from major cracks (Danger Zone). There is a possibility (low) that earthquake or volcanic activity may start from this area. 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



The Vanuatu Meteorology and Geohazards Department continues to closely monitor this volcano activity.
More information will be provided when necessary.

Bulletin N°9- Lopevi Activity

VANUATU VOLCANO ALERT BULLETIN N°9 - LOPEVI ACTIVITY
Thursday September 29th 2022

LOPEVI VOLCANO 
16°30’23”S 169°20’18”E Summit 4635ft (1413m)
Current Vanuatu Volcano Alert Level: Level 2

 

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

Lopevi volcano activity is continuing in the major unrest state. With the current state, the volcanic activity is likely to increase at any time but it could also remain at the same level. Volcanic hazards remain on the island of Lopevi due to the current ongoing volcanic activity. The danger zone for life safety is limited to on the island of Lopevi.

Latest observations and analysis of the Lopevi seismic data from the volcano monitoring system confirm the Lopevi ongoing volcanic activity. The activity is located in the active craters near the summit crater. The volcano activity consists of continuous emission of steam plume.

In the past, small or short-lived eruptions have followed volcanic unrest at Lopevi. The chance for an eruptive phase to follow the current volcanic unrest, like in January 2017, is likely.

The Lopevi Volcanic Alert Level (VAL) has been at Level 2 since 23 September 2017. The current observations are consistent with the activity of the Volcanic Alert Level 2. Level 2 indicates ‘Major level of unrest; Danger zone is on the island of Lopevi’. With this current volcanic activity, it is a useful reminder that eruptions can occur with little or no warning.


Lopevi is one of several frequently active volcanoes in Vanuatu. Ash producing eruptions can occur every 3-10 years. The volcano has been active during historical time at both summit and flank vents, producing moderate explosive eruptions and lava flows that reached the coast. Historical eruptions date back to the mid-19th century. The island was evacuated following major eruptions in 1939 and 1960. Only a family tries to live on the island these days.


This is a reminder that all visitors to Lopevi may be affected by the volcanic unrest. It’s very important that authorities, communities, villages from the islands of Paama and Epi take this information into consideration.

The Vanuatu Meteorology and Geohazards Department will continue to closely monitor this volcanic activity. More information will be provided when necessary.

Bulletin N°9- Tanna Activity

VANUATU VOLCANO ALERT BULLETIN N°9 - TANNA ACTIVITY
Thursday September 29th 2022

TANNA VOLCANO 
19°32’0”S 169°26’30”E Summit 1184ft (361m)
Current Vanuatu Volcano Alert Level: Level 2

 

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

New observations on the ground suggest that the Yasur volcanic activity continues to produce moderate to low explosions with emission of steam and ash including volcanic bombs that fall inside and around the crater. With this current activity and ongoing presence of volcanic gases and/or volcanic ash around the summit crater, the danger zone remains at 600 meter around the volcanic cone. The danger zone for life safety is at Danger Zone A (See Yasur caldera safety map below).
 

Latest analysis of the Yasur seismic data from the volcano monitoring system confirms that Yasur volcano activity is continuing in the level of major unrest. The activity consists of ongoing strong explosions with gas plumes and/or volcanic ash plumes. Some explosions remain intensified and volcanic projectiles or bombs may fall in and/or around the crater.
 

The Yasur Volcanic Alert Level (VAL) has remained in Level 2 since the 18th October 2016. The current observations are consistent with the activity of the Volcanic Alert Level 2. Level 2 indicates ‘Major level of unrest; Danger zone is now at 600 m around the volcanic cone. With this current volcanic activity, it is a useful reminder that eruptions can occur with little or no warning.
 


Advice to all tourism agencies, visitors, local authorities, people from Tanna Island and general public that with this current activity and ongoing presence of volcanic gases and/or ash around the crater, the danger zone (Danger Zone A) remains at 600 m around the volcanic cone. The level of risk for visitors accessing areas from the parking area to the crater rim (Danger Zone A) remains high. With this current level of activity, villages located close to the volcano may continue to expect volcanic gases and/or ash falls impact, especially those exposed to wind direction.
