Will Hawaii's Vog Caput Our Way?
Bellamy Pailthorp, my colleague at KNKX, in addition to I choose gotten several emails from folks worried nigh the effluent from Hawaii's Kilauea volcano in addition to whether it mightiness hold upward heading our way.
So let's verbalize nigh it. Influenza A virus subtype H5N1 major eruption is currently occurring on the Big Island of Hawaii associated amongst the Kilauea volcano. This eruption, actually an enhancement of an ongoing eruptive trial starting 1983, is non explosive in addition to putting solely child amounts of ash into the atmosphere. But it is emitting large amounts of sulfur dioxide (SO2), hydrogen sulfide (H2S), H2O vapor, in addition to other gases.
The sum of SO2 emitted past times Kilauea is immense, amongst some days the emissions reaching 2000 tons. SO2 tin give the sack combine amongst H2O to make sulfuric acid in addition to sulfate particles. SO2, sulfuric acid particles, in addition to other volcano effluents tin give the sack combine to for a grayish haze called VOG, which tin give the sack non solely cut down visibility, only tin give the sack choose detrimental effects on lung function.
And amongst this eruption that choose been enough of minor to moderate earthquakes (see below).
Up until this this point, the northeasterly merchandise winds choose been blowing most of the VOG out to sea, leaving air character pretty decent on the large isle (see below).
But changes inward the merchandise winds may convey the volcanic effluent presently into to a greater extent than populated areas. Influenza A virus subtype H5N1 friend of mine, Professor Steve Businger, of the University of Hawaii, runs a VOG prediction effort, inward which they work numerical models to predict the crusade of volcano effluent or then the Hawaiian islands.
Let me demo yous their model-based probabilities of SO2 concentrations exceeding .01 parts per 1000000 (ppm) for the side past times side day. The map from this morning time (around 10 AM PDT) shows most heading out to sea.
But equally nosotros persuasion the forecasts for the upcoming days, to a greater extent than of the SO2 is swinging or then the large isle in addition to heading into the heavily populated Kona area. Some fifty-fifty swings upward to Oahu.
One affair is clear...none of the SO2 in addition to VOG are headed our way, then nosotros tin give the sack relax.
Hawaii is a beautiful place, only it has its environmental challenges--like real heavy pelting (e.g., on Kauai), VOG, earthquakes, tsunamis, in addition to more.
