On Ambae, after a general evacuation in September, the inhabitants started to reintegrate their island, but they find themselves in a situation more than uncomfortable.
The strong fallout of ashes due to the current activity, possibly hydromagmatic, pollutes the water reserves, and defiles the cultures of cabbage and taro. Acid rain is feared.
Local authorities claim that their request for the supply of breathing masks, sunglasses and head covers to national authorities has "fallen on deaf ears". There is urgency for these supplies and for drinking water supplies.

Sheveluch's activity disrupts some overhead aerians lines over Alaska.
Dave Schneider, of the Alaska Volcanic Observatory, claims that the ash cloud from Sheveluch volcano, on the Kamchatka Peninsula in Russia more than 2,000 km away, had an explosion on Tuesday and sent a cloud of ash at about 26,000 feet in the atmosphere. The plume drifted over parts of northern Alaska on Wednesday.
