Batu Tara volcano in Indonesia. The volcano is currently producing small ash plumes.
I was distracted enough by trying to figure out a way to teach about Miller Indices that I plum forgot to post this week's USGS/SI Weekly Volcanic Activity Report. It was a fairly quiet week so you didn't miss much. Enjoy it at your leisure.
Rabaul must be positioned on the globe in such a way that NASA's Aqua satellite always gets a good shot at it. The Earth Observatory posted a new image of the plume from Rabaul and it looks thicker and more ash-laden than the image posted a few weeks ago. What this says about any potential future activity at Tavurvur crater at Rabaul is unclear, but it does show that the volcano is on a constant "simmer" right now.
