Ah, I was wondering about that. Sat view shows populated areas 10 miles away at most, NE of Mt. Keiler. The main(?) airport is slightly north of due west of the volcano, also a bit under 10 miles away.
Um, were those winds the surface winds, or jet stream? (Could be mid-layer too, but that’d not show except in detailed met. reports.)
Surface and mid level. The Jet blows towards the S-SE in that area.
