just over a day (approx 28 hrs) between the 2 5.2 quakes Only separated by about 2km. I'm glad I'm nowhere near it, it would be horrific the number of quakes

and now Date Time Latitude Longitude Depth Magnitude Quality Location Wednesday 24.09.2014 06:59:58 64.676 -17.418 1.0 km 3.7 99.0 6.6 km NE of Bárðarbunga Not quite as shallow as the previous but very much in the same area

expect some updates this morning -- no manual checking after 21:21, probabilities all lower than 99% -- so automatic. But doesn't look as though there's anything over 3 overnight

A lot of steam rising tonight viewed from Camera 2

I noticed they were getting closer to the surface. Not a huge amount of separation between the quakes in terms of distance either, I think as one fault pings the next up the line stresses and the itself goes

I think it will keep us waiting, we've had significant quakes (M4+) for over a month, could just keep going. I think the main point is that it even has the experts guessing

Coming thick and fast now M3+ at least every couple of hours since midnight Date Time Latitude Longitude Depth Magnitude Quality Location Tuesday 23.09.2014 07:57:20 64.671 -17.485 6.9 km 4.0 99.0 4.0 km NNE of Bárðarbunga Tuesday 23.09.2014 06:18:24 64.679 -17.462 8.0 km 3.5 99.0 5.3 km NE of Bárðarbunga Tuesday 23.09.2014 04:33:55 64.683 -17.418 4.9 km 5.2 99.0 7.1 km NE of Bárðarbunga Tuesday 23.09.2014 01:54:06 64.676 -17.415 8.0 km 3.6 99.0 6.7 km NE of Bárðarbunga Tuesday 23.09.2014 01:51:51 64.656 -17.379 0.5 km 3.9 99.0 7.3 km ENE of Bárðarbunga Tuesday 23.09.2014 00:06:57 64.682 -17.422 7.9 km 3.0 99.0 6.9 km NE of Bárðarbunga One very shallow at 01:51

All seeming to get quite a bit shallower. They quakes are still being reported late, I looked at the site about 90 mins ago and there was nothing

Just the 3 overnight that are over M3. Date Time Latitude Longitude Depth Magnitude Quality Location Monday 22.09.2014 05:28:28 64.677 -17.473 4.9 km 3.5 99.0 4.9 km NNE of Bárðarbunga Monday 22.09.2014 03:13:57 64.683 -17.495 8.7 km 3.7 99.0 5.0 km NNE of Bárðarbunga Monday 22.09.2014 00:19:07 64.683 -17.488 8.9 km 3.6 99.0 5.1 km NNE of Bárðarbunga Look how close the earlier two are, looks like about 100m between them horizontally and 200m vertically.

Cheers Sainsbo, Got my Orders of Magnitude mixed up. You are right, it is 175,000 times the amount of energy. I see another 4.2 since your comment as well (JP's already mentioned it) Back up in the North Eastern side. Would be lovely if we could see what each of these quakes are doing, My assumption (especially looking at the GPS) is that the ring faults are weakening around most of the cladera and the additional weight of the ice is increasing the EQ strength

Interesting that the number of smaller quakes definitely seems to be dropping and the energy released in one big one (like the 5.5 mentioned by Sainsbo) is equivalent to over 3,000 in the M2 range

Some great info there rusty -- the number of quakes in the North Eastern quadrant show that there's a lot happening there and supports JP's theory of a flank collapse. I wonder whether there is any inflation on that flank? As for that NASA video, great find PL-- amazing -- glad I wasn't the pilot

Yes, 3 over M3 in the north/east quadrant and 2 in the south/east quadrant wonder whether the first 2 (one ENE and one NNE) set off the third (which was spal bang in the middle (NE)

I agree that it's very small, but wasn't sure whether you were saying it would or wouldn't have an effect

There's active and there' ACTIVE. Look at this lot Saturday 20.09.2014 17:11:41 64.675 -17.472 8.4 km 5.0 99.0 4.7 km NE of Bárðarbunga Saturday 20.09.2014 17:05:49 65.138 -16.323 7.7 km 1.7 99.0 4.2 km SSE of Herðubreið Saturday 20.09.2014 17:05:47 64.611 -17.496 1.0 km 4.4 99.0 3.6 km SSE of Bárðarbunga Saturday 20.09.2014 17:04:48 64.616 -17.475 4.8 km 4.0 99.0 3.7 km SE of Bárðarbunga Saturday 20.09.2014 17:02:02 64.674 -17.484 7.3 km 3.6 99.0 4.3 km NNE of Bárðarbunga Saturday 20.09.2014 17:00:56 64.671 -17.403 7.7 km 3.4 99.0 6.8 km ENE of Bárðarbunga Stress around the caldera now starting to ripple it's way out as soon as a quake hits,. look sto me as those faults are very stressed and one of them only 1Km down You only need 10 M5 quakes to be equivalent to an M6 (but 100 M4). Anything over M5 brings us closer to what I expect will be an interesting eruption. We are also now getting closer to new moon, sun and moon acting together, molten rock is much denser than water, but there will still be an effect

Sharp fall in the number if quakes since the 2 X M3.3 quakes this morning. Seems to keep doing this -- biggish quake drop in numbers -- slowly ramp back up -- biggish quake, drop in numbers,, etc etc

I'm in North Norfolk and saw the towers from Norwich airport about 5:00, then lovely and sunny for 10 miles whereas home is in murk off the sea, apparently been misty all day

This looks quite a bit further north than most Friday 19.09.2014 04:52:31 64.736 -17.509 8.0 km 3.2 99.0 10.6 km N of Bárðarbunga Still in the 6-8km depth area

Much quieter since midnight, Nothing over M2. Seems to have a cycle of agitation, a big quake then quiet until the next run. I think that JP's concerns about the North East flank are well founded, but, as Jon FR has said on numerous occasions, we are in unexplored (or at least previously unmeasured) territory. Even from here it could just settle down and go back to sleep, but with the number of quakes over M4 in the caldera, this has to be the least likely scenario to happen. Much more likely is an eruption in the caldera, if that happens we need to look at the lava type to determine to overall effect, basaltic flood lava will produce a lot of gas, but not much in the way of explosive activity, rheolite on the other hand may produce a lot of explosive activity and ash.

And now there's this one Date Time Latitude Longitude Depth Magnitude Quality Location Thursday 18.09.2014 06:05:17 64.669 -17.389 0.3 km 3.4 99.0 7.3 km ENE of Bárðarbunga Note the depth only 0.3km -- shallowest I've noticed here. Possibly ice fracturing and falling either into water or a void?

Nothing large since just before midnight, cameras still not working. What's happening -- no idea Reminds me of that Kitkat ad from a few years back. Been updated now with a 4.5 just after 03:00

Turned out to be a M5.4 again up on the North East quadrant. When I get time I must look at what % of quakes have been on the eastern side of the caldera, from memory I feel it's about 75% Date Time Latitude Longitude Depth Magnitude Quality Location Tuesday 16.09.2014 21:34:12 64.692 -17.378 7.7 km 5.4 99.0 9.2 km NE of Bárðarbunga After a period where the quakes appeared to be rising towards the surface, the last few (of the big ones) have been deeper again. Interesting that the quakes since that big one have been very small, wonder how long before before another big one comes, they seem to vary between 6 and 18 hours

Not necessarily. The ring faults will absorb a certain amount of stress without noticable movement, but then they'll go with a bump

The plume looks dark tonight, could just be a trick of the light Very quiet after that strange one this morning Several small ones along the fissure

Actually been revised to 3 km, so not quite as close to the surface. Several other quakes less than 1 km though. Wonder if the very shallow quakes are ice fracturing as it falls into water.Hi John, beat me to it
