Following an assessment during 7-12 July, the Geohazards Observatory team concluded that explosive activity at Yasur had slightly increased, becoming stronger and more frequent, and shifting from Strombolian to sub-Plinian.
[Remark: Sub-Plinian is probably esaggerated and would imply ash columns of 10 km and more height, which are almost certainly not occurring. ] [less]

Variuous media are talking about "giant ash clouds", that could disrupt flights across the Pacific.
While it's understandeable that the trauma of the Icelandic eruption of Eyafjallajökull volcano in April has news reporters now on high alert about potential ash clouds threatening flights, it is exaggerated to classify Yasur's eruption as "giant" (so far). Local flights to and from Tanna, might very well be affected, but however impressive and violent Yasur's strombolian eruptions might seem for now, an ash cloud reaching mere 2 km has certainly no potential to seriously disrupt international trans-Pacific flights.
