VANUATU VOLCANO ALERT BULLETIN N°1 - VANUA LAVA ACTIVITY
Tuesday January 30th 2018

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

 

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

Volcano activity at Vanua Lava is continuing at the level of unrest state. Its Alert Level remains at Level 1. Danger is restricted to visitors approaching the volcanic cone and the area around the Sulfur River; Risk is around the volcanic cone and the Sulfur River.

Latest observations confirm presence of volcanic gases near the volcano and around the sulfur river. The local population and visitors can smell the volcanic gases while approaching the volcanic area.

Alert Level for Vanua Lava volcano was at Level 1 since 27th May 2016. Current observations are consistent with the Alert Level 1 activity. Level 1 indicates ‘Signs of unrest’; there is signs of unrest and possible danger near eruptive vent .

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 volcan had low infrequent activity except in XIX century with 3 moderate manifestations and in XX century with 2.

This is another reminder to all tourism agencies, visitors, local authorities, and people from Vanua Lava Island and general public 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.

Bulletin N°1- 2018

VANUATU VOLCANO ALERT BULLETIN N°1 - GAUA ACTIVITY
Wednesday January 31st 2018

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

 

Volcanic Activity at Gaua shows signs of imminent increase. Its Volcanic Alert Level has moved from Level 1 to Level 2 .

Volcano activity at Gaua is in the level of major unrest state and its Alert Level is now at Level 2. Danger is restricted to visitors approaching the volcanic cone; Risk is around the volcanic cone.

Latest observations done from December 2017 to January 2018 confirm that the activity consists of ongoing volcanic steam cloud which may content volcanic gases. These observations and seismic analysis confirms that the volcano activity has increased to the major unrest state. Visitors approaching the volcano may smell volcanic gases.

Alert Level for Gaua volcano was at Level 1 since 21st December 2010. Based on its slight increased seismic activity and observation of ongoing volcanic gas emission and steam plumes in December 2017 and January 2018, the Volcanic Alert Level (VAL) was raised to Level 2. The current observations are consistent with the Alert Level 2 activity. Level 2 indicates ‘Major Unrest’; Danger is around the crater rim and specific area, considerable possibility of eruption and also chance of flank eruption .

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.

Advice to all tourism agencies, local autorities, people of Gaua and the general public 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.

VANUATU VOLCANO ALERT BULLETIN N°1 - AMBAE ACTIVITY
Monday January 29th 2018

AMBAE VOLCANO 
15°24’0”S 167°50’0”E Summit 4908ft (1496m)
Current Vanuatu Volcano Alert Level: Level 2

 

Volcanic activity at Ambae is continuing in the major unrest state; Its Alert Level remains at Level 2 .

The volcanic eruption at Ambae confined inside the Lake Voui is stable. New scientific analyses suggest that there is no imminent risk of increasing activity. The Volcanic Alert Level remains at Level 2. The restricted area of risk is now limited within 2 km from the active vent in Lake Voui.

Observations photos taken on December 2017 and January 2018 confirm that the activity continue from the volcanic cone (island) which was built during the latest eruption. Style of Ambae volcano activity has changed with explosions and volcanic cloud emitted are mostly white which means only steam. With the current size of the volcanic cone in Lake Voui, people from Ambae may hear explosions, view a minor volcanic ash and/or gas plume and glows over the mountain at night. The activity at Ambae is like what is seen and experienced at Yasur on Tanna Island.

These observations and the analysis of seismic data confirms that the volcano activity continue at the level of major unrest state. The volcano activity consist of ongoing emission cloud of gases, ashes and volcanic bombs that may fall around the volcano vents.

The eruption at Ambae started on 6th September 2017, when the Volcanic Alert Level was raised to Level 3. The style of eruption has changed around 22nd September 2017 when Geohazards staff observed lava (molten rock) at the surface for the first time. This was a significant change and raised the level of uncertainty about the development of the eruption. The volcanic Alert Level was also raised at that time to Level 4. With more observations and the analysis of seismic, gas, thermal and deformation data by scientists from the Geohazards Division of the Vanuatu Meteorology and Geohazard Department (VMGD) and the international counterpart, it is confirmed that the volcano has settled in a more stable state of activity, therefore the Alert Level was dropped to Level 3 on 6th October 2017. Based on its slight decreased seismic activity and observation of ongoing volcanic gas emission and steam plumes on the web camera in December 2017, the Volcanic Alert Level (VAL) at Ambae was dropped to Level 2 on 7th December 2017. With the continuous close monitoring, the nature of this volcano activity is more understandable. Therefore the current observations are consistent with the Alert Level 2 activity (Similar to Yasur). Level 2 indicates ‘Major Unrest’; Danger is around the crater rim and specific area, considerable possibility of eruption and also chance of flank eruption .

Ambae volcano is a very large volcano and is frequently active. In the recorded history, there have been many eruptions, every 10-50 years over the past 150 years. All have been from the summit craters, except one recorded in 1670’s when a lava flow occurred in the Ndui Ndui area. The current eruption is focused in the summit crater and there are no indications of activity elsewhere on Ambae Island.

This a reminder to all tourism agencies, local autorities, people of Ambae and the general public not to access the Danger Zone which is about 2 km radius from the eruptive vents. In this area volcanic gases, ashes and projectiles are expected (See map below). Villages from Ambae island may experience volcanic hazards from gas and ashes especially those 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 as available.

VANUATU VOLCANO ALERT BULLETIN N°1 - AMBRYM ACTIVITY
Tuesday January 30th 2018

AMBRYM VOLCANO 
16°15’00”S 168°07’00”E Summit Elevation 4377ft (1334m)
Current Vanuatu Volcano Alert Level: Level 2

 

Volcanic activity at Ambrym is continuing in the major unrest state; Its Alert Level remains at Level 2 .

The volcanic activity at Ambrym is continuing at the level of major unrest; new scientific analyses suggest that there is no imminent risk of increasing activity. As a consequence, the Volcanic Alert Level remains at Level 2. The volcanic activity is likely to continue in this state. Danger is restricted to visitors approaching the active craters; The restricted area of risk is limited in 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 photo below).

Observation photos from December 2017 to January 2018 confirm that the activity is not changing. Field observations show the activity consists of ongoing lava lake activity in Benbow and Marum craters inducing ongoing substantial degassing and emission of steam cloud. Visitors approaching the volcanic area and craters can smell the volcanic gas.

These observations and the analysis of seismic data confirm that the volcano remains at the major unrest state and the volcano activity consist of ongoing emission cloud of gases.

Alert Level for Ambrym volcano was 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 is around the crater rim and specific area, considerable possibility of eruption and also chance of flank eruption .

Ambrym volcano is a very active volcano in Vanuatu with large caldera of 12 km diameter and 2 active craters lakes 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 reached coast. Historical eruptions dated back to two century with 8 important eruptions with lava flows extra-caldera having caused destruction in coastal areas in 1820, 1894, 1913 or 1929. Over seventy years, there are no extra-caldera eruptions.

This is a reminder to all tourism agencies, local autorities, people of Ambrym and the general public 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 be present in abundance occasionally.
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 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 as available.

VANUATU VOLCANO ALERT BULLETIN N°1 - LOPEVI ACTIVITY
Tuesday January 30th 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; Its Alert Level remains at Level 2 .

The small 7-km-wide conical island of Lopevi (Vanei Vollohulu) continues to show signs of volcanic unrest. Observation photos from December 2017 to January 2018 show that the activity at the volcano is continue to occur in the active craters below the summit crater. Observations photos and satellite images confirm the activity consists of ongoing gas and steam cloud. No eruptions are currently occurring.

In the past volcanic unrest at Lopevi has led to small or short-lived eruptions. There is a chance some eruptions may follow the actual unrest.

The Alert Level for Lopevi (VAL) remains at Level 2 since 23 September 2017. The current observations are consistent with the Alert Level 2 activity. Level 2 indicates ‘Major Unrest’; Danger around the crater rim and specific area, considerable possibility of eruption and also chance of flank eruption .

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 another 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.

Tuesday January 30th 2018

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

 

Yasur volcanic activity is continuing in the major unrest state. Its Alert Level remains at Level 2 .

Yasur volcanic activity is continuing at the level of major unrest. New scientific analyses suggest that there is no imminent risk of increasing activity. The alert level for Yasur remains at Level 2. Danger is restricted to visitors approaching the crater; Risk is in the Permanent Exclusion Zone which is always closed (Shouldn’t be Access) and about 395 m around the eruptive vents (See photo below).

Latest observation and analysis of seismic data confirm that explosions remain strong and volcanic bombs may fall in and/or around the crater. Eruptive vents may emit volcanic ashes and gases plume. Nearby villages from the volcano may be affected by ash falls and volcanic gases especially those exposed to trade wind direction.

Alert Level for Yasur was 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 is around the crater rim and specific area, considerable possibility of eruption and also chance of flank eruption .

Yasur is the best known and most frequently visited of the Vanuatu volcanoes, has been in more-or-less continuous Strombolian and Vulcanian 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 the one of the youngest Holocenes volcano (11 700 years to present) of Vanuatu.

This is another reminder that all tourism agencies, visitors, local authorities, people from Tanna Island and general public to must not access the Permanent Exclusion Zone which is about 395 m around the eruptive vents. In this area volcanic projectiles, ashes and gases will always be expected (See photo below).
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.

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