Thursday November 15th 2018

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

 

Vanua Lava volcano is continuing 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.

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.

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.

Observations and satellite data in October and November 2018 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 smelt 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°10- Ambae Activity

VANUATU VOLCANO ALERT BULLETIN N°10 - AMBAE ACTIVITY
Wednesday November 14th 2018

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 level of major unrest state. The Volcanic Alert Level remains at Level 2 .

Ambae volcano activity becomes stable. The current volcanic activity is consistent with Volcanic Alert Level 2. Possible imminent eruption could occur at any time in such major unrest state. The Danger Zone for life safety is limited at 2 km radius from the active vent and areas located in the Yellow Zone (See Map below).

Observations in October and November 2018 confirm that the volcanic cloud emitted are white colour, means only steam.

The presence of ash that has fallen on Ambae during the last eruption will 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.

These observations and the analysis of seismic data confirm that the volcano activity is in the major unrest state. The volcano activity consist of ongoing emission of steam and/or volcanic gases. The local population and visitors can smell the volcanic gas while approaching the volcano.

Significant impact of ashes and gases emission to villages at Ambae started in March and July, 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 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 current eruption episode started in 1991, with eruptions in 1995, 2005, 2016 and 2017. The current eruption is focused in the summit crater and there are no indications of activity elsewhere on Ambae Island for now.

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

Current Vanuatu Volcano Alert Level: Level 2

 

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

The volcanic unrest continues at Ambrym. The volcanic activity is likely to continue at similar levels, consistent with Volcanic Alert Level 2. The Danger Zone for life safety is limited at the Permanent Exclusion Zone at Benbow which is about 1 km around Benbow crater and the Danger Zone A at Marum (including Maben-Mbwelesu, Niri-Mbwelesu and Mbwelesu) which is about 2.7 km around Marum crater (See Safety Map below).

Observations and the analysis of seismic data in October and November 2018 confirm a continuous volcanic activity in the major unrest state and is confined in Benbow and Marum craters. The activity consists of ongoing active lava lake inside the active vents inducing sustained substantial degassing and emission of steam cloud. Gas will be continue to be smelt while approaching the volcanic area and craters.

Alert Level for Ambrym volcano has been at the Level 2 since 7 December 2017. The current observations are consistent with the Alert Level 2 activity. Level 2 indicates ‘Major Unrest; Danger Zone is at 1 km around Benbow crater and 2.7 km around Marum’ .

Ambrym volcano is a very active volcano in Vanuatu with large caldera of 12 km 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 2015 is focused in the caldera.

All tourism agencies, local authorities, people of Ambrym and the general public are reminded not to access the Permanent Exclusion Zone which is about 1 km radius from Benbow and Danger Zone A is about 2.7 km radius from Marum . In these areas volcanic gases may occasionally be present in abundance .
See the safety map and visitors Fact-Sheet of Ambrym volcano at the website www.vmgd.gov.vu/vmgd/index.php/geohazards/volcano/volcano-info/resources.
Villages located further away may experience volcanic hazards from gas and steam plumes, especially villages exposed to prevailing trade winds direction.

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

Bulletin N°8- Lopevi Activity

VANUATU VOLCANO ALERT BULLETIN N°8 - LOPEVI ACTIVITY
Thursday November 15th 2018

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

 

The volcanic unrest continues at Lopevi. The Volcanic Alert Level remains at Level 2 .

The small 7-km-wide conical island of Lopevi (Vanei Vollohulu) continues to show signs of volcanic unrest. The volcanic activity is likely to continu at similar level, consistent with the Alert Level 2. The Danger Zone for life safety is limited to on the island.

Observations and analysis of seismic data in October and November 2018 confirm a continuous volcanic activity in the major unrest state. The activity continues to occur in the active craters near the summit crater and consists of ongoing volcanic gas and steam emissions. No eruptions are currently occurring.

In the past, small or short-lived eruptions have followed volcanic unrest at Lopevi. There is a chance some eruptions may follow the current unrest, like in January 2017.

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. Today very few people live on the island.

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.

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 level of 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).

Observations and seismic data analysis in October and November 2018 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 ashes cloud. Gas will be continue to be smelt 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 be impacted by ash falls and volcanic gases, especially those exposed to prevailing trade winds direction.
