Another Icelandic volcano eruption on the cards

Seismic activity continues to be high.
Biggest earthquake in the current swarm was measured this night at 01:26. According to USGS the magnitude was 5.7. The event was localized in the northern/northwestern part of Bardarbunga caldera at 6 km depth.
Most of the seismic activity is close to the rim of Dyngjujokull. The dyke is still migrating to the north and the tip of it is already around 10 km outside of the glacier. Most of the events are at the depth of 8-12 km.
There have been no signs of harmonic tremor.
Biggest 'quake so far then... I had to look up 'dike' - it's the bit at no6 Biggest earthquake in the current swarm was measured this night at 01:26. According to USGS the magnitude was 5.7. The event was localized in the northern/northwestern part of Bardarbunga caldera at 6 km depth.

Harmonic tremor frequently indicates an imminent eruption as it signals moving magma and gases (I believe).
The importance of being near the rim of 'Dyngjujokull' is that it's the glacier, so the eruption may occur outside of the glacier, and so not create the dangerous ash clouds like last time.

Tell us more about this explosion from your rim.Harmonic tremor frequently indicates an imminent eruption as it signals moving magma and gases (I believe).

Now children, enough bum jokes! unconfirmed 3.3 quake at 30km depth 10 minutes ago. It's not over yet!

And another 3.2, this time at 1.9km depth. She's gonna blow!

4.6 at 8km. It's looking lively.
I'm not the only one hoping for a natural disaster to liven up a fairly mundane start to Autumn then!

Hmmm should my flight to Italy a week on Friday be cancelled i'll be most disgruntled.
What do airlines do if they cancel your flight due to volcanoes?
And does anyone know an insurance company that covers volcanic eruptions?

Being stuck out there isn't an issue, it's being stuck before I go that's the issue.

That some would include my wife who regards me as the most selfish person she has ever met. But as I've just ordered her a new E class she can foxtrot Oscar ! She does have some point though I leave her in the UK as I swan around Europe.
I would suggest we have a "Who is the most selfish pig" competition when we meet up in Lucca later in the year once we have got settled in October. Assuming you are in Italy and not stranded in another part of the world awaiting the volcanic eruptions to dissipate and air travel to return given your globe trotting. Having looked at the Icelanadic details it seems less likely that an eruption will cause widespread disruption currently. However as I said earlier on this thread geomorphological events are not really suited to humans: the timescales are just totally different. Be good to see you over there I am looking forward to it! Stick with the selfishness: it is an awful lot more fun!
Well, I am finding this link (posted above) highly addictive...

There appears to be some smoke now where there wasn't any earlier, and there continues to be lots of tiny little tremors at various depths. This is like some really slow reality TV show that I cannot turn off.

Latest news:
Scientists from the Icelandic Meteorological Office and the Institute of Earth Sciences, together with representatives of the Civil Protection in Iceland, met today to discuss the on-going unrest at the Bárðarbunga volcano.
Conclusions of the Scientific Advisory Board:
Intense seismicity continues. Over 700 earthquakes have been recorded since midnight. Earthquakes are occurring mostly beyond the edge of the Dyngjujökull glacier and the intrusion itself has migrated about 1 km northwards since yesterday.
At 00:16 UTC today, a magnitude 5.3 earthquake occurred in the caldera of Bárðarbunga. At 02:50 UTC, another similar-sized earthquake (magnitude 5.2) took place in the same region.
At 01:52 UTC, a magnitude 4.5 earthquake was detected on the eastern side of the Askja volcano. This was followed by a few micro-earthquakes in the same area.
The dyke intrusion beneath Dyngjujökull is thought to be about 40 km in length.
Modelling of GPS data indicates that about 20 million cubic metres of magma have been added to the volume of the intrusion in the last 24 hours.
Modelling results suggest that the dyke intrusion is causing stress changes over a large area, including the region to the north of the dyke's extent; this could account for the increased seismicity at Askja volcano.
There are no indications that the intensity of the activity declining.
From today, the afternoon status report will no longer be produced. However, if the situation escalates (i.e. imminent signs of an eruption), daily status reports will be reintroduced. The results of the scientific advisory board will continue to be distributed daily at around midday.
