According to Vanuatu's volcano monitoring agency Geohazards, the "volcanic activity at Ambrym is showing drastic changes." The alert level for Benbow and Ambrym volcanoes was raised from 2 to 3 (on a scale of 1-5). ...more
What exactly the nature of the reported increased activity is was not specified in the report, unfortunately. Likely, it consists of a combination of increased detected seismic activity, degassing and high levels of lava lake activity which all could be precursors of potentially dangerous explosions from the active craters, in particular at Benbow and Marum (but also including the smaller vents of Maben-Mbwelesu, Niri-Mbwelesu and Mbwelesu).

During our most recent Vanuatu volcano expedition, a small group stayed 4 days and nights in the Ambrym caldera. Expedition leader volcanologist Yashmin Chebli reported: ...more
"... I confirm the presence of a permanent and continuous activity of both lava lakes inside the Benbow and Marum craters. "The lava lakes levels are relatively low, about 5m less compared with the previous year in 2016. The surface of both lava lakes is also more reduced about 30% for Benbow and 50% for Marum.
