Volcano thread

It's continuing to erupt but at a lower intensity. However, as Vulkane.net notes today, the ash from previous emissions, plus this ongoing stuff, is indeed a major problem. Darwin VAAC (1430Z) notes that there is still ash present at 50,000 feet and:

RMK: HIGH LEVEL VA TO FL500 IS DETACHED FROM THE VOLCANO AND MOVING SW. CONTINUOUS VA EMISSION TO FL150 MOV SE, WITH REMNANTS OF VA FROM EARLIER ERUPTION STILL PRESENT. VA HEIGHT AND FORECAST BASED ON SATELLITE IMAGERY AND MODEL GUIDANCE.

Badan Geologi tweets confirm that the volcano can't be seen visually.

It's worth noting that Indonesia, and particularly Java, is having a terrible time with wildfires, including peat fires. The last I read, children were staying indoors at home, doing online learning because of bad air quality. I haven't read anything about a potential ash-wildfire smoke combo air pollution crisis but wonder if this might become an issue with wind shifts -- maybe not, if AK keeps to lesser intensity activity and the wind shift clears out the ash.
 
No changes; just came across this video, which is gorgeous.

 
This one's not pretty, but wow! That eruption column was amazing.



Some videos that are more current show Anak Krakatau now sputtering fireworks and having other strombolian activity as it typically does...and as it was doing, though more intensively, on the night that it collapsed in 2018.

Everyone is still watching it very closely.

The three main things this layperson is wondering:

  • What caused the outburst (paroxysm)?
  • Did that violent outburst weaken the edifice?
  • Will it go back to recent baseline or escalate again?
