Before it gets lost in the mists of time/finals, here is the weekly volcano report brought to us by the USGS and the Smithsonian Global Volcanism Program.
Highlights (not including Mayon, Soufriere Hills or Piton de La Fournaise):
- Fuego in Guatemala produced ash plumes that reached 4.1-4.7 km / 13,500-15,400 ft along with avalanches of volcaniclastic debris.
- Also in Guatemala, lava flows erupted from Pacaya, traveling hundreds of meters from the main vent area.
- Manam in PNG produced an 3 km / 10,000 foot ash plume as part of its renewed activity this year.
- The lava dome on Nevado del Huila in Colombia continues to glow - and produce significant ash, one with a plume that reached 7 km / 23,000 feet.

Maybe I should just apologize right here and now for that title, but dang, I liked it.
Anyway, I've seen a lot of plume images cross my browser/inbox over the last day, so I thought I'd post a few of them.
Your weekly dose of volcanic activity from the USGS/SI. (a little late thanks to an exciting day of column chemistry).
Some highlights include:
Quick hit post from beautiful Walnut, Iowa, but this was too interesting to pass up...
Bright plume spotted on Venus, image taken by the ESA Venus Express.
All the volcano news that is fit to print, all thanks to the USGS/Smithsonian GVP!
Manam is still active... that's interesting, I wonder if that eruption that wasn't at Karkar was actually from Manam. They are not too far apart but I have no idea how the VAA reports are created.. visual observation by pilots might result in that kind of error I guess.
Here is a recent article where scientists are trying to sort through precursors to eruptions.

West Mata volcano, an active seamount whose summit lies approximately 1100 m below sea-level, was explored during a Vents Program cruise in May 2009, and I think two photos and two little video clips were released at the time. The volcano was seen in vigorous eruptive (effusive and explosive) activity. Now more, and extremely high-resolution video and photographic material has been released, which you can download at the Vents Program web site (movie files up to 1 GB ... !!!)

Great Post! Itâs very nice to read this info from someone that actually knows what they are talking about.
I know I'm a little late in adding my comments but this particular blog post made me think. It was an engrossing piece. I have become a returning reader of your site since I came across your site a while back. I can't say that I agree with everything you stated but it was emphatically fascinating! I will be back again soon.
Interesting article. Well done, i hope to read more like this
Insightful writing! I will take a bit of time to entertain this writing.
