The latest Weekly Volcanic Activity Report from our friends at the Smithsonian Global Volcanism Program and the USGS.
Highlights (not including Eyjafjallajökull - you can check the latest IMO update on that eruption and the latest VAAC ash advisories.):
- Villarrica in Chile was raised from Alert Level 1 to 2 by the Chilean SERNAGEOMIN after an increase in seismicity, a rise in the lava lake levels at the summit and more vigorous fumarolic activity.
- In the first update in a while, a small ash plume was noticed at Chaiten in Chile, rising to ~1.8 km (8,000 feet) from the new domes.
- Karymsky in Russia continues to produce ash plumes that reach as high as 4.6 km (15,000 feet) along with a thermal anomaly at the summit for several days.
- Costa Rica's Turrialba continues to emit volcanic gases from the fissures that opened at the beginning of 2010.

Though airplanes are starting to take off from various parts of continental Europe, UK airspace will remain locked down for at least another day. Eyjafjallajökull's ill temper has been an unexpected object lesson in the complexity and interconnectedness of our environment, technology, and social…
Last week, I was fortunate to be able to attend the opening of a Smithsonian Museum of Natural History exhibit dedicated to the rescue of 33 miners from the San José mine in Chile, and meet two of miners whose story captivated the world as they endured 69 days underground following a mine…
As the three remaining readers may have noticed, I've been a bit too busy to blog for a couple of weeks.
But other blogs go on, and right now, over on SciBling "Eruptions" there is a fascinating live discussion in the comments on the possibility of an imminent eruption in Eyjafjallajökull.…
An activity occurred on Katla.

Here is the second video from my trip to Eyjafjallajökull area where the ash fall has happened.

Since the volcano tremor started to drop I have been recording a series of pules. I don't know at the moment if they are long period volcano type earthquakes or not.
But these events are not human made I think and they appears to be increasing in frequency it seems.
@Jón FrÃmann: that seems interesting. I wonder what's going on.
Would you mind posting again some samples in SAC format? Just for personal curiosity, even knowing the limitations of the instrument you're using compared to a more expensive seismometer.
@Jón F - did you mean to post#2&3 on the Eyja page instead of here? I found the second video and your comment on tremor by accident...please share if that was your intent! Ditto Mr. Moho.
@Mr. Moho, you can find the files at www.jonfr.com/sac , no rar file this time around.
@birdseyeUSA, No I planned to place it here. Maybe it was a mistake. But the other thread has gone quite long. But I am going to put the link there now. :)
What link are people using for THEY? The link I bookmarked doesn't take me to the page I remember, which was a stack of line graphs for each of four or five GPS locations, including GOD. (That's the only one I remember.) Now I can only seem to find individual pages for two of the locations. Anyone? Thanks.
@6: thanks for sharing!
frir showing renewed activity
flir sorry for fat fingers
I find it amazing how much the ash in the air is a effective IR filter in many ways better than a bit of fog
a nice north wind in desirable
@Carla (#7) Try http://hraun.vedur.is/ja/Katla2009/stodvaplott.html#googtrans/auto/en
carla this will give you the gps at they and some others scroll down http://hraun.vedur.is/ja/Katla2009/
@Gina, @Henrik - thanks. I've got those already. I forgot that the dashboard page has a THEY chart, though. Appreciate the links.
The USGSSI Weekly has always seemed to me like a poor way to monitor new and ongoing volcanic activity. Something like the old expression about things being 'a day late and a dollar short' comes to mind. Would really appreciate knowning if there isn't a better, 'official' (or university) website that gives volcanic activity reports as they occure. If we can monitor worldwide seismic activity by the minute, where's the worlwide volcanic activity monitoring 'by the minute'?
Thanks for spreading the word about this.
Interesting post, I look at us again and hope more of them to read.
