As with all articles I have read previously on this incident, I have seen no mention of 'Notams', and why no consideration as to changing the routing was given on this occasion. I used to be familiar with operating on this and other routes in the area over many years, and 'Notams' issued along with Met briefings tended to headline current volcanic action since Indonesia is riddled with them. Is it possible that this high level micro silicon infused dust cloud was not expected? Maybe someone here knows what I'm missing....

Mount Galunggung did not have a NOTAM or IVOL issued as far as I am aware, that became a matter of some urgency thereafter. A month later, a Singapore Airlines B747 lost 3 out of 4 engines from further eruption of the same stratovolcano.
There was no official report on this event issued by the AAIB, and the KNKT/NTSC doesn't show a report on the incident. KLM 867, a B744 had all 4 shut down over Alaska in 1989, and did an emergency recovery to PANC.
