Ground deformation has been observed on Katla.

Could we soon see an eruption from Eyjafjallajokull's 'Angry sister'?

Yes, worth watching I think. from John Search

Katla Volcano, Iceland
An earthquake swarm has occurred near Katla volcano in Iceland. The largest earthquake in the swarm measured magnitude 3.2 on the evening of 1st September. The seismic activity occurred under Mýrdalsjökull glacier in southern Iceland which covers Katla volcano. The volcano has not erupted however there has been increasing interest in Katla since the eruption of nearby Eyjafjallajokull in 2010.

Updated info on Katla, seems there is some melting going on under the glacier:

Mount Tambora alert status raised to 3 (out of 4).

Thing is, if Tambora blew to her full capacity, and gave us another "year without summer" as it did in 1800's.....would we really notice the difference here in the UK? Lol!

Katla is having harmonic tremors it seems, will soon likely to erupt. There was earthquake swarm there yesterday, but today it has been bit more quiet.

Webcam is shaking, but I think its just fixed to mast and wind shakes it. View is right now bit foggy out there.

I can't look it since it needs plugin, and I can't install that for some reason.

Katla is having serious quake swarm, and you can clearly see some harmonics there, I guess this is closest seismograph:
hraun.vedur.is...

Those harmonics started 8th day, notice how its more low frequency movement.

Yes it is a swarm- how serious remains to be seen. Until the magnitudes go up a bit more, not likely they would alert.

Really? Where? Harmonics? So you have access to the raw data and have done spectral and/or audio analysis to determine harmonics? No, of course you haven't- cause PuterMan and myself were just discussing how it would be interesting to have access to some of that raw data for exactly that: analysis. If you would know who to contact there that could provide that data (and that speaks English) that would be great.

Harmonics by definition are recurring intervals. They show up on spectral as bands. And as PuterMan has shown us much, they have a very distinctive whale type sound when the raw data is converted to an audio file and sped up to bring it into human hearing range.


... I guess this is closest seismograph:
hraun.vedur.is...


Actually, I believe for Katla you want this one:
hraun.vedur.is...

There seems to some confusion going on here about the use of the term harmonics and tremor as it applies to volcanoes. And although those are somewhat uncommon type of charts, correct me if I err, but I don't see anything close to harmonic tremor on the graph I linked to at Katla (Godabunga)- and that's even if you could see real harmonic tremor on them at all- and I'm not sure what it would look like on that type of graph. Any ideas PM?

And yeah, I have returned from purgatory- thanks to a most forgiving staff.

You can't distinguish "volcanic" harmonic tremor on these kind of graphs.
The only reading that could indicate possible "volcanic" harmonic tremor is if the low freq 0.5-1 HZ line (red one) went up in the sky or started to look quite strange. This could be a sign that there actually is magmatic activity as it would shows up in that kind of range on these graphs. Even if we saw that red line going completely wild it could just mean tectonic activity caused by low magnitude earthquakes.

You can also have harmonic readings caused by hydrothermal activity. (water, vapour)
On these graphs you won't detect them but you would see the blue/cyan line going "wild" or up. And for me that's what we are, more or less, seeing on TrueAmerican's posted graph. Thermal or Hydrothermal activity at Katla under the Icecap and not volcanic harmonic tremor.

Question:

Okay so I was looking over the RSOE website and noticed the activity at Tambora. I did a little reading and here's my question. If Tambora blows, should we expect it to be as big as it's last eruption considering it was only just under 200 years ago? Has it had enough time for the chambers to fill back up? Or is there no way for us to know? Okay that was like 3 question lol. Thanks in advance.

Did anybody notice that Iceland had quite a bit of activity this morning? It looks a bit ominous...
