Bulletin N°7- Vanua Lava Activity

VANUATU VOLCANO ALERT BULLETIN N°7 - VANUA LAVA ACTIVITY
Thursday July 25th 2019

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 unrest state. 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. The  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 that due to the current volcanic activity, the danger zone remains at around the sulfur river and volcano area. In thèse 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°7- Gaua Activity

VANUATU VOLCANO ALERT BULLETIN N°7 - GAUA ACTIVITY
Thursday July 25th 2019

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 remains 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 that due to the current volcanic activity, the danger area remains at the volcanic cone. In this area volcanic gases will always be expected and other volcan 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°7- Ambae Activity

VANUATU VOLCANO ALERT BULLETIN N°7 - AMBAE ACTIVITY
Thursday July 25th 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 at the caldera remains at 2 km radius from the active vent. The Danger Zone for life safety remains limited at the Danger Zone A (See Safety Map below). An additional Danger Zone is located within the area of flowing creeks during heavy rain.

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.

Alert Level for Ambae has been at the Level 2 since 21st September 2018. Observations of the current activity are consistent with the Alert Level 2 activity. Level 2 indicates "Major unrest; Danger Zone remains at 2 km radius from the volcanic cone and areas inside the Yellow Zone"The possibility that Ambae volcano activity escalate to the level of minor eruption (Level 3) and/or lowered to the lower unrest state (Level 1) is low for now .

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 that due to the current volcano activity, the danger zone remains at the Danger Zone A which is set about 2 km radius from the eruptive vent. Volcanic gases will always be expected in this area. Due to the presence of the volcanic ashes deposit at the summit of the island during the last eruption villages near flowing creeks (Dangerous Flows Zone) can continually expect changes in stream behavior and flow rates streams during heavy rains. villages from Ambae island may experience impacts of volcanic gases especially those exposed to prevailing trade winds direction, see the Ambae Volcano Advice Key Messages at this link:
http://www.vmgd.gov.vu/vmgd/index.php/geohazards/volcano/volcano-info/resources and others hazards related to the volcanic activity may be expected.

Bulletin N°7- Ambrym Activity

VANUATU VOLCANO ALERT BULLETIN N°7 - AMBRYM ACTIVITY
Thursday July 25th 2019

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

 

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

The volcanic activity at Ambrym is continuing at the level of major unrest. New scientific analyses suggest that the volcano activity is likely to continue at this level. The Danger Zones at the caldera remains at 1 km around Benbow and 2 km around Marum craters including Maben-Mbwelesu, Niri-Mbwelesu and Mbwelesu) (See Safety Map Fig.1). The Danger Zone for life safety remains limited at the Permanent Exclusion Zone at Benbow and Danger Zone A at Marum. An additional Danger Zone at the South-East of Ambrym remains within 1 km from major cracks (See Safety Map Fig.2).

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

Current observations and analysis of seismic data recorded from the monitoring station confirm an ongoing seismic activity at the vicinity of the volcano with emissions of steam. Lava lakes that used to appear in Benbow and Marum craters have disappeared since 16th December 2018. People from Ambrym and neighbouring islands may no longer see the volcanic glow at night for the next few weeks/months.

Alert Level for Ambrym has been at the Level 2 since 14th February 2019. Observations of the current activity are consistent with the Alert Level 2 activity. Level 2 indicates "Major unrest ; Danger is now at 1 km around Benbow, 2 km around Marum and 1 km from major cracked areas in the Sout-East part of Ambrym".
The possibility that the Ambrym volcano activity escalate to the level of minor eruption (Level 3) and/or lowered to the lower unrest state (Level 1) 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. The December 2018 eruption was focused in the summit caldera, and affected the Eastern Fracture or Rift Zone with just a ground deformation and uplift, but no eruption occurred there.

All tourism agencies, local autorithies, people of Ambrym and the general public are reminded that due to the curent volcanic activity, danger area 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. Following the seismic activity in December 2018, weak layers or areas of these danger zones can collapse any time. Due to the presence of active faults at the South-East area of Ambrym, communities concerned are advised not to access 1 km from major cracks (Danger Zone). There is a possibility (low) that volcanic activity may start from this area.
See the Ambrym Volcano Advice Key Message at this link: https://www.vmgd.gov.vu/vmgd/index.php/geohazards/volcano/volcano-info/resources.
Villages of Ambrym may experience impacts volcanic 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°7- Lopevi Activity

VANUATU VOLCANO ALERT BULLETIN N°7 - LOPEVI ACTIVITY
Thursday July 25th 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 continuing 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 remains 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°7- Tanna Activity

VANUATU VOLCANO ALERT BULLETIN N°7 - TANNA ACTIVITY
Thursday July 25th 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 level, consistent with Volcanic Alert Level 2. The danger zone remains at 395 m around the eruptive vents. The Danger Zone for life safety is limited in the Permanent Exclusion Zone (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 remains 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 that due to the current volcanic activity, the danger zone remains at the Permanent Exclusion Zone which is set about 395 m around the eruptive vents. In this area volcanic projectiles, 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.
