Manaro Voui Vanuatu Third Ring of Fire Volcano To Erupt Past Week (see AWESOME video below)  – Manaro Voui  also known as Aoba or Lombenben, is a shield volcano on the island of Ambae.  Manaro Voui is one of the most dangerously active volcanoes in the world, but is only one of 17 volcanoes in Vanuatu with 13 of those being active.

Vanuatu volcanoes on the Ring of Fire include: Ambae, Ambrym, Aneityum, Eastern Gemini Seamount, Futuna, Gaua, Hunter Island, Kuwae, Lopevi, Matthew Island, Merelava, Mota Lava, Trairor’s Head, Ureparapara, Vanua Lava, Vot Tande and Yasur.

What is the Ring of Fire?

The Ring of Fire is a major area in the basin of the Pacific Ocean where many earthquakes  and volcanic eruptions occur. In a 25,000 mile horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and plate movements. It has 452 volcanoes (more than 75% of the world’s active and dormant volcanoes).

Ambae Island

The island of Ambae, which is the emergent portion of Vanuatu’s largest volcano, rises 4,908 feet above sea level, or about 12,795 feet above the sea floor.

Earlier this month, based on satellite data, webcam observations, and wind model data, the Wellington, New  Zealand Volcanic Ash Advisory Center reported that during July 17 t0 24, ash plumes from the vent at Ambae’s Lake Voui rose to altitudes of 2.1-5.5 km (7,000-18,000 ft) a.s.l. and drifted N, NE, E, and SE.

Rumbling noises were reported at Penama Provincial Headquarters at Saratamata, more than 30 km away. Volcanologists conducting field work in the areas noted widespread damage and disruption to the local population; roads going to thewest part of the island had been washed away.

The island of Ambae, one of about 65 inhabited islands in Vanuatu, was temporarily evacuated last September when Manaro Voui eruption cycle began. Since March, authorities have been encouraging people to permanently relocate by offering residence on two neighboring islands.

Vanuatu Red Cross has been evacuating residents this week as volcanic activity causes chaos on Ambae Island, the charity reported on Facebook. The Red Cross post stated on July 24, 2018 at 10:18 pm,  “Mass evacuation happening now in South of Ambae, as the situation is worsening with Lombenben ash falls. Red Cross Disaster Management Coordinator & Ambae Disaster response Operation controller Augustin Garae confirmed that an evacuation is underway as villages in Ward 2,3,4 are not longer inhabitable. We tried to travel to the South today but we have to turn back, because trees are falling, visibility is very very poor, we cannot see far more than 2 meters.The situation is getting worse now in the South, people are now leaving their homes and move to Evacuation centers in the East”.

On July 26, 2018, Foreign Minister Ralph Regenvanu tweeted: “On the eve of the 38th anniversary of independence, cabinet has reimposed the state of emergency and ordered the compulsory evacuation of the entire population of Ambae.”

Volcano Manaro Voui History

Recent past activity, some including eruptions, were in 1575, 1670, 1916, 1966, 1991, 1995, 2005, 2016 and September 2017.

November 27, 2005, a steam and ash eruption began leading to a Level 2 volcano alert and preparations for evacuations.  From late November 2005 to mid-February 2006 explosions from Lake Voui resulted in the formation of a pyroclastic cone in the lake. By late November 2006 the side of the cone was breached, and its central crater filled with lake water. The Vanuatu Meteorology and Geo-Hazards Department (VMGD) reported intermittent increases in degassing activity between 2006 and August 2017, and minor ash emissions during June-July 2011 and August 2016.

On September 28, 2017, after a week of increasing volcanic activity to Level 4 (Level 5 being a major eruption), the government of Vanuatu ordered a complete evacuation of the island 11,000 residents. Ash from the eruption had covered the island, killing crops and polluting the air and water.

An explosive eruption from a new pyroclastic cone in the lake began in mid-September 2017 and lasted through mid-November.

In April 2018 the remaining approximately 10,000 residents were ordered to evacuate permanently. As of July 27, many were still living on the island.
