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

 

Vanua Lava volcano continue to show signs of unrest. The Volcanic Alert Level remains at Level 1 .

The volcanic unrest continues at Vanua Lava. The volcanic activity is likely to continue at similar levels, consistent with the Volcanic Alert Level 1. Danger Zone for life safety is limited around the volcanic area and the Sulfur river.

Current observations confirm ongoing presence of volcanic gases near the volcano and around the sulfur river. Gas will be continue to be smelt while approaching the volcanic area.

Alert Level for Vanua Lava volcano has been at the Level 1 since 27th May 2016. Current observations are consistent with the Alert Level 1 activity. Level 1 indicates ‘Signs 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 century with 3 moderate manifestations and in XX century with 2.

All tourism agencies, visitors, local authorities, and people from Vanua Lava Island and general public are reminded to must not approach the volcano and the sulfur river. In these areas, volcanic gases will always be expected .

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

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 volcanic unrest continues at Gaua. The volcanic activity is likely to continue at similar levels, consistent with the Volcanic Alert Level 2. The Danger Zone for life safety is limited to on the volcanic cone.

Latest observations and satellite data confirm a continuous volcanic activity in the level of major unrest state. The activity consists of ongoing volcanic steam cloud which may content volcanic gases. Gas will be continue to be smell while approaching the volcanic cone.

Alert Level for Gaua volcano has been at Level 2 since 31st January 2018. The current observations are consistent with the Alert Level 2 activity. Level 2 indicates ‘Major Unrest;Danger is around the volcanic cone’ .

Gaua volcano is one of the active volcano in Vanuatu. Construction of the historically active cone of Mount Garet 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 not to access the Gaua volcanic cone. In this area volcanic gases will always be expected and other volcano risks 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°1- Ambae Activity

VANUATU VOLCANO ALERT BULLETIN N°1 - AMBAE ACTIVITY
Monday January 7th 2019

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 .

Ambae volcano activity remains at Level 2. Imminent eruption could occur in such major unrest state. The Danger Zone for life safety remains at 2 km radius from the active vent and areas located in the Yellow Zone (See Map below).

The volcanic ashes that fell on Ambae during the 2017 and 2018 eruption could continue to change the behaviour of streams and creeks when it rains. The creeks and streams can produce floods and carry a lot more debris (sands, gravel and boulders). The flow path of streams and creeks could change due to the flood debris. Landslide may occur at some areas during heavy rain fall.

Latest observations and analysis of seismic data recorded from the monitoring station confirm that the volcano activity is in the major unrest state (Level 2). The volcano activity consist of ongoing emission of steam and/or other volcanic gases. Villages exposed to dominant winds could expect to find volcanic ashfalls deposits and smell volcanic gases.

Significant impact of ashes and gases emission to villages at Ambae started in March and July 2018, when the Volcanic Alert level was raised to Level 3. Observations of the current activity are consistent with the Alert Level 2 activity. Level 2 indicates ‘Major unrest; Danger is now at 2 km around the volcanic vents and areas inside the Yellow Zone’ . The possibility that the Ambae volcano activity escalate to the level of minor eruption (Level 3) is now low .

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 the crater is now filled by Lake Voui; the modern active vent area underlies Lake Voui. 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 eruption episode 2018 started in 1991, with eruptions in 1995, 2005, 2016 and 2017.

All tourism agencies, local authorities, people of Ambae and the general public are reminded not to access the danger zone which is about 2 km radius from the eruptive vent. Volcanic gases and ashes are expected in this area. Villages in the Yellow Colour may continue to expect change in streams and creeks flows during heavy rain fall (See map below). Villages from Ambae island may experience impacts of volcanic gases and ashes, especially those exposed to prevailing trade winds direction and others hazards related to the volcanic activity may be expected

Bulletin N°1- Ambrym Activity

VANUATU VOLCANO ALERT BULLETIN N°1 - AMBRYM ACTIVITY
Monday January 7th 2019

AMBRYM VOLCANO 
16°15’00”S 168°07’00”E Summit Elevation 4377ft (1334m)
Current Vanuatu Volcano Alert Level: Level 3

 

Eruptive activity at Ambrym is continuing in the minor eruption state. The Volcanic Alert Level remains at Level 3 .

Ambrym volcano is continuing in the minor eruption state. The Danger Zone for life safety remains at the Danger Zone B which is about 2 km around Benbow and 4 km around Marum craters (including Maben-Mbwelesu, Niri-Mbwelesu and Mbwelesu) (See Safety Map below). The additional area of risk is within 3 km from major cracks in the South East of Ambrym .

Though people are not feeling strong earthquakes compare to the past few days in December 2018, current observations and analysis of seismic data recorded from the monitoring network confirm an ongoing seismicity. This is related to the current volcano eruption. This seismicity may continue to affect the existing cracks, especially in the South East Ambrym area. Latest satellite imagery analysis confirm ongoing remarquable land deformation on Ambrym island, therefore people from Ambrym and neighboring islands may continue to expect earthquakes, volcanic gases and ashes at any time.

The Alert Level for Ambrym volcano has been at the Level 2 since 7 December 2017. The volcanic activity on 15th December 2018 show that Ambrym volcano is undergoing a small scale eruption. This is consistent with the Alert Level 3 activity. Level 3 indicates ‘Minor eruption; Danger is now at 2 km around Benbow and 4 km around Marum with major cracked areas in the south eastern part of Ambrym’ . The possibility that the Ambrym volcano activity escalate to the level of moderate eruption (Level 4) is low for now.

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, there are no extra-caldera eruptions. The eruption of 1988 and 2015 are focused in the caldera.

All tourism agencies, local autorithies, people of Ambrym and the general public are reminded not to access the Danger Zone B which is about 2 km radius from Benbow and 4 km from Marum. In this area volcanic ashes and gases may be unbearable. Moreover, communities from South East Ambrym are advised not to access 3 km radius from major cracks which are vulnerable to possible flank eruptions.
See the Ambrym Volcano Advice Key Message at the website https://www.vmgd.gov.vu/vmgd/index.php/geohazards/volcano/volcano-info/resources

Villages of Ambrym may experience impacts of ashes and gases plumes and acid rains when it rains, especially those exposed to prevailing trade winds.

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

Bulletin N°1- Lopevi Activity

VANUATU VOLCANO ALERT BULLETIN N°1 - LOPEVI ACTIVITY
Monday January 7th 2019

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 unstable 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 for a longtime. The Danger Zone for life safety is limited to on the island.

Current observations and analysis of seismic recorded from the monitoring network confirm a high unrest volcanic activity in Level 2. The activity continues to occur in the active craters near the summit crater and consists of ongoing emissions of steam and other gases.

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 Alert Level (VAL) has been at Level 2 since 23 September 2017. The current observations are consistent with the Alert Level 2 activity. Level 2 indicates ‘Major Unrest;Major Unrest; Danger Zone is around the Lopevi island’ .

Lopevi is one of several frequently active volcanoes in Vanuatu. Ash producing eruptions can occurred 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 this 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 as available.

Bulletin N°1- Tanna Activity

VANUATU VOLCANO ALERT BULLETIN N°1 - TANNA ACTIVITY
Monday January 7th 2019

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

 

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

The volcanic unrest continues at Yasur. The volcanic activity is likely to continue at similar levels, consistent with Volcanic Alert Level 2; The Danger Zone for life safety is limited in the Permanent Exclusion Zone which is always closed (Shouldn’t be Access) and about 395 m around the eruptive vents (See Safety Map below).

Latest observations and analysis of seismic data recorded from the monitoring network confirm a continuous volcanic activity in the level of major unrest state and is confined in the crater. The activity consists of ongoing explosions. Some explosions remain strong and volcanic bombs may fall in and/or around the crater. Eruptive vents may emit volcanic gases and/or ash clouds. Gas will be continue to be smell while approaching the caldera and crater.

Alert Level for Yasur has been at the Level 2 since 18th October 2016. The current observations are consistent with the Alert Level 2 activity. Level 2 indicates ‘Major Unrest; Danger Zone is at 395 m around the eruptive vents ’ .

Yasur is the best 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.

All tourism agencies, visitors, local authorities, people from Tanna Island and general public are reminded not to access the Permanent Exclusion Zone which is about 395 m around the eruptive vents. In this area, volcanic bombs, ashes and gases will always be expected .
See the safety map and visitors Fact-Sheet of Yasur at the website www.vmgd.gov.vu/vmgd/index.php/geohazards/volcano/volcano-info/resources .
Villages located close to the volcano may continue to expect ash falls and volcanic gases, especially those exposed to prevailing trade winds.

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