Today I operated the second of 2 flights that Air NZ operated to Tonga. Unfortunately the photos don't do it justice as they are just from a phone camera through cockpit windows but they will give you some idea.
The underwater volcano is about 35 nm NNW of the airport. The plume in the photos extends to about 22,000ft. Instead of the usual easterly wind this time of the year it was a Norwesterly which couldn't be worse.
The plume is mostly steam but there is some ash in the lower levels. None of it reached the airport. There was a bit of haze and a very light smell of SO2.
Unfortunately the NZ Volcanic service issued a forecast that has the ash trail spreading across the airfield later on so the 3rd flight (another 767) was cancelled as a precaution.
I certainly wouldn't want to operate there at night.
