Scientists detected a patch of mud at the tuff cone built during the eruption of 2005. The entire surface of Lake Vui showed increased evaporation and inhabitants of a nearby village have noticed abnormal activity since December 2012. Satellite measurements showed increased SO2 emission rates between 18 and 25 January.
Geohazard maintains the Volcanic Alert Level of Aoba at Level 1. The area of risk remains near the Manaro Voui crater. "This volcano activity may remain as it is and decrease but there is a low probability of neglecting the gradual increase of the alert in the coming months", Geohazard writes.

The eruption at Manaro volcano continues at low levels with mainly phreatic activity. A cone is building up inside the lake forming a small island inside the lake. There are two active vents, one of which ejects water, rocks and mud and the other is producing a tall column of steam and gas (up to 8-10,000 feet). A group of New Zealandean volcanologists has recently visited the volcano and sent the following more detailed reports: ... read all

The eruption at Mt. Manaro volcano on Vanuatu's island of Ambae, that had started on 27th of Nov. 2005, is continuing at low or decreasing levels (although drawing a lot of media attention, probably because little other significant volcanic events are occurring at the time). Ash and steam plume rose to a maximum of about 3 km (10,000 ft) height into the air as observed on Thursday 7 Dec. According to the optinion of monitoring volcanologists there are no indications at present that the eruption might escalate. The eruption is occurring from a vent in the middle of the crater lake Vui — before the eruption known as a picturesque blue lake; this is also the main reason for the intense production of steam. ... read all
