USGS/SI Weekly Volcanic Activity Report for May 12-18, 2010

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 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.
