Bulletin N°3- Vanua Lava Activity

VANUATU VOLCANO ALERT BULLETIN N°3 - VANUA LAVA ACTIVITY
Thursday April 29th 2021

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 analyses 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°3- Gaua Activity

VANUATU VOLCANO ALERT BULLETIN N°3 - GAUA ACTIVITY
Thursday April 29th 2021

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

 

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

The Gaua volcano activity is continuing at the major unrest level, consistent with the Volcanic Alert Level 2. New scientific analyses suggest that this volcano activity is likely to continue at this same level of major unrest. Volcanic hazards remain on the Gaua volcanic cone (e.g. volcanic gases). The danger zone for life safety is limited to on the volcanic cone.

Latest observations and satellite data confirm that the activity consists of ongoing volcanic steam cloud which may contain volcanic gases. 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.

All tourism agencies, local authorities, people of Gaua and the general public are reminded that due to the current volcanic activity, the danger area remains at the volcanic cone. In this area volcanic gases will always be expected. Visitors may expect impact of this gas while approaching this area 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°5- Ambae Activity

VANUATU VOLCANO ALERT BULLETIN N°5 - AMBAE ACTIVITY
Wednesday May 5th 2021

AMBAE VOLCANO 
15°24’0”S 167°50’0”E Summit 4908ft (1496m)
Current Vanuatu Volcano Alert Level: Level 1

 

Volcanic activity at Ambae has slightly increased in the level of minor unrest. The Volcanic Alert Level remains at Level 1

The current Ambae volcanic activity is consistent with the Volcanic Alert Level 1. Latest observation images captured by the monitoring webcam on 4th and 5th May 2021 shows an emission of steam cloud from the eruptive vent inside the lake Voui.

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 (e.g. remobilization of remaining ash from 2017 and 2018 eruption).

Latest observations and analysis of the Ambae seismic data from the volcano monitoring system confirmed the slight increase of Ambae volcanic activity at the minor unrest level (Level 1). The volcano activity consists of emission of steam from the eruptive vent inside the lake Voui. People from Ambae and neighbouring island may observe the volcanic plume at the summit area of Ambae.

The Volcanic Alert Level (VAL) for Ambae has been at Level 1 since 23rd September 2019. Observations of the current activity are consistent with the activity of the Volcanic Alert Level 1. Level 1 indicates ‘Minor level of unrest; 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 warning.

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 behaviour and larger than normal flow rates during heavy rains. People of Ambae Island need to beware of the dangerous flows while approaching these creeks during heavy rains. More information about the volcanic hazards can be found on the website:

Bulletin N°4- Ambrym Activity

VANUATU VOLCANO ALERT BULLETIN N°4 - AMBRYM ACTIVITY
Thursday April 29th 2021

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.

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

Some volcanic hazards do remain 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.

Latest observations and daily analysis of the Ambrym seismic data from the volcano monitoring system confirm that the Ambrym volcano activity conditions remains stable and its activity is continuing at the low level of unrest. The lava lakes that used to appear in Benbow and Marum craters have disappeared since the December 2018 eruption. The remaining activity inside both craters consists of ongoing steam emissions. People from Ambrym and neighbouring islands will not see the volcanic glow at nights.

Open cracks in the South-East Ambrym that formed during the December 2018 eruption may continue to open due to erosion. Major earthquake activity could continue to affect these cracks and weak layers or areas around the actives craters.

The Volcanic Alert Level (VAL) for Ambrym has been at the Level 1 since 10th October 2019. Observations of the current activity are consistent with the activity of the Volcanic Alert Level 1. Level 1 indicates ‘Minor level of unrest. Danger zone remains at 1 km around Benbow, 2 km around Marum and 500 meters from major cracked areas in the South-East part of Ambrym’. With this current volcanic activity, it is a useful reminder that eruptions can occur at any level of unrest with little or no warning.

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 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°4- Lopevi Activity

VANUATU VOLCANO ALERT BULLETIN N°4 - LOPEVI ACTIVITY
Thursday April 29th 2021

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 to be unstable in the level of major unrest. With the current state, the volcanic activity is likely to increase at any time but it could also remain at the same level for a longtime. 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 daily analysis of the Lopevi seismic data from the volcano monitoring system confirm that Lopevi volcanic activity conditions remains unstable and its activity is currently continuing in the high level of unrest. The activity continues to occur 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°4- Tanna Activity

VANUATU VOLCANO ALERT BULLETIN N°4 - TANNA ACTIVITY
Thursday April 29th 2021

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 emits plumes of volcanic gases and/or ash. With this current activity with 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 limited in the Danger Zone A (See Yasur caldera safety map below).

Analysis of the latest Yasur seismic data from the volcano monitoring system confirms that Yasur volcano activity remains in the level of major unrest state. The activity consists of ongoing explosions with gas plumes and/or volcanic ash. Some explosions remains intensified and volcanic projectiles or bombs may fall in and/or around the summit crater.

The Yasur Volcanic Alert Level (VAL) has been at the Level 2 since 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 remains 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.

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 Holocenes volcano (11 700 years to present) of Vanuatu.

Advice to all tourism agencies, visitors, local authorities, people from Tanna Island and general public that with this current activity and the presence of volcanic gases and/or ash plumes around the crater, the danger zone (Danger Zone A) remains at 600 meter around the volcanic cone. The level of risk for visitors accessing areas from the crater rim to the parking area (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.
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 Department of Meteorology and Geohazards will continue to closely monitor this volcano activity. More information will be provided when necessary.
