Since the last update, Aoba (Ambae) volcano continues to show low levels of unrest. However, volcanic hazards remain at the summit area and creeks (e.g. remobilization of remaining ash from 2017 and 2018 eruption). The danger zone at the summit remains limited in the Danger Zone A (See safety map). This danger zone (Danger Zone A) has a 2 km radius from the 2017-2018 active vents. An additional danger zone is within areas of flowing creeks during heavy rain.

There is no obvious emission of volcanic ash or gas from the eruptive vent(s) of Lake Voui (like it was in 2017-18). The volcanic ash that fell on Aoba during the 2017 and 2018 eruption will continue to influence the behaviour of streams and creeks when it rains. The creeks and streams can produce floods and carry debris (sands, gravel and boulders). The flow path of streams and creeks could change due to the flood debris. Landslide may also occur at some areas during heavy rain fall.

The Volcanic Alert Level (VAL) for Aoba has been at Level 1 since 23rd September 2019. A reminder that a volcanic eruption on Aoba could occur at any level of unrest and with little warning. Aoba volcano is a very large volcano and is frequently active.
