The Vanuatu Geohazards Observatory has published a fresh update on the situation at Gaua volcano, which has recently shown an increased level of activity, forcing evacuations. Gaua Bulletin No. 3, dated 24 November (but only just published on the Observatory’s website) reports ‘a big explosion of the Gaua volcano in November 18th 2009 at 2pm’ followed by ‘very thick and high emissions of ash columns that were covering the areas exposed to trade winds in the West’. Photographs show the comparative size of the ash plume on 31 October and 18 November. The bulletin also notes that there was an increase in seismicity at the volcano from 25 October onwards.

The alert level for Gaua remains unchanged at 2 (‘moderate eruptions’).
