The Iceland Volcano Thread

This morning parts of UK Airspace were closed as the ash erupted from the Eyjafjol volcano (starting yesterday) drifted across it. Ths stuff is pretty deadly if it gets into aircraft engine intakes. The airspace closure so far affects Scotland and NI so far but the cloud is drifting south. Current visible imagery shows…

Which that? I can't see anything more than there was earlier or maybe I am just cross-eyed with tiredness.

Ah stop, all this excitement before bed. If anything else happens tonight perhaps you'd be good enough to shake me awake.

I'm becoming a trembore.

Maybe a little tsunami sweeping down from the Artic Sea and spilling over into the Atlantic... much better than snow.

albeit a fart in the wind, eyjafjallajokull (copied and pasted ) has recorded a tremor, the first in a long time.

just a note.

mag 3 tremor at bardarbunga
http://en.vedur.is/earthquakes-and-volcanism/earthquakes/vatnajokull/
Bárðarbunga is an Icelandic stratovolcano located under the ice cap of Vatnajökull glacier, rising to 2,009 m (6,591 feet) above sea level, making it the second highest mountain in Iceland, just about 101 m lower than Hvannadalshnjúkur.

A magnitude 2 at Katla now also. These are of course small tremors. However, most tremors recorded in iceland in recent months range between 0.5 and 2 magnitude. Let's see if the pattern continues

You got there before me. Looking good for the 12th October club.

ETA: It's a 3 at Katla and a 2 at Bardabunga, Wolfe. Just looked again. They've changed them again. The 3 has disappeared from both sites. Someone in Iceland Met is taking the pee.

At Vatnajökull, very shallow and with a few aftershocks.

Nowhere near Eyjafjallajökull or Katla though so I don't think there is anything to worry about here?

these quakes are being recorded at depths of 1-2kms only.
http://www.emsc-csem.org/Earthquake/earthquake.php?id=190324

this is a proper swarm.

the quakes were recorded to the south of Bárðarbunga

The largest lava flow in Iceland and the entire earth from a single eruption is originated from Bárðarbunga about 8500 years ago. The lava is believed to be 21-30 cubic kilometers and covers approximately 950 square kilometers.

Many large prehistoric eruptions have occurred southwest of the glacier and two after settlement in Iceland, Vatnaöldur eruption about 870 and Veiðivötn eruption 1480. Both were large eruptions that would have major effects on life in Iceland and neighboring countries were they to repeat in modern times.

Smaller eruptions are frequent northeast of Bárðarbunga in an ice-free area called Dyngjuháls. Such an eruption last occurred in 1862-4.

Studies of tephra layers have shown that a number of eruptions have occurred beneath the glacier itself, probably in the northeast of the crater or in Bárðarbunga. This eruption appear to follow a cycle, several eruptions were in the glacier between 1701-40 and since 1780. There has been an eruption in the glacier or the system since 1864. Frequent earthquakes in Bárðarbunga indicate that the volcano will erupt sooner or later.

ps...any chance we could move this into icelandic volcano thread so as not to lose track

The 3.5 has been downgraded to a 2.9, depth adjusted to 7.7 km.
13 more EQ's registered within 5km of Hamarinn since then, including a 3.9 (but that is only at 90% quality so may get downgraded a bit too).

Edit : Now they have changed the first EQ back to 3.5 and downgraded the second big one to 3.7

I came across this while looking for info on the Loki-Fögrufjöll volcano. Are they scaring each other for the fun of it and to support the 2012 theory or is there any actual basis in fact? In my next life I'm going to come back as a vulcanologist and be able to make educated comments.

Katla has been seismically active for at least the past forty years, with two distinct areas predominating - Gooabunga rise in the west, and within Katla caldera in the centre. Earthquakes are more common during the autumn than during spring. There is almost no seismicity at the beginning of the year, and the earthquakes start to
occur in late summer.

could that be the reason of incresed earthquakes!!!

Thats not really a reason. It could be that ice melt from the glacier during summer comes in contact with heated rock that causes some of the tremors. Its hard to imagine any other reason why its a seasonal thing. That might explain the quote you provided. Where did you find that quote? Sounds a bit crazy.

Wouldn't ice melt take pressure off the ground and this could result in tremors as the ground springs back up, less at the beginning as the pressure increases with increased ice build up.
