  • Episode 42 has ended.
  • Ep 42 ended at 09:93 UTC per webcam and vona. So2 and volcanic ash still obsd. Moving southwest. Large shield of SO2 extends southwest of srnmost pt with volcanic ash clouds obsd moving southwest through the SO2 weather cloud cover developed over plume so uncertain in exact extent of SO2 and volcanic ash. Models forecast volcanic ash to continue moving wsw to southwest with xpctd by t+12. Hosley.
