I suppose it depends on what you call a large volcanic event really. VEI 7 is not huge when you consider VEI 8 at 10 times the volume, and then you think about the Siberian traps, the Deccan traps etc massive extrusions of magma covering millions of sq kilometers to some possible 7 million and containing maybe as much a 2 million cu km of material or more at present day not allowing for erosion. Yellowstone was 1000 to 2000 cu km depending on which eruption. The traps are up to 2000 time bigger again. Oh and then you have Thera at 100 cu km. Just not in the same class I am afraid. Bit of a non-event in world class terms.

Not sure of the exact equivalent but it is approximately like if the traps were a Mag 5.4, Thera was a Mag 1

By the way the QVSData program is available again with USGS, EMSC, GeoNet and GeoScience (Australian quakes only)

If you have any problems leave me a message on the QVSData Help thread in my signature.

Took them a while then! I thought they weren't going to bother.

Oh well, proves the theory! Normally once they have decided it is an explosion they delete them.

Morning Puters,

First, in fairness to hellas, I would like to go a little 'psychological'. Nobody in living history has lived through a VEI7. We have only experienced maybe a 3 or 4 at worst, I could be wrong, and I'm sure you'll put me right. Krakatoa was an ESTIMATED VEI6 and as you have explained the difference between a 6 and 7 is huuuuge! I understand how your 'mathematical' head can equate and balance the differences...but Hellas is coming from the 'experience' if you will, perspective. Krakatoa was the first documented account of a volcanic eruption of this size. Any previous 'guestimations' have been on geological evidence. However we don't have any first hand accounts giving is at least some idea of how anything around or above a VEI7 was like.

As to these 'explosive' EQ's in the channel....is it just me, but don't you think it's rather weird that we still have these 'mines' still going off, some 65 years later? I lost a great uncle, who was a Captain of one of the hundreds of ships to one of these mines during the evacuation. My point is, that there seems to me to be an increase in said 'earthquakes' about 5-6 that I remember in the last 18 months and all off this part of the north coast of France. Now I can understand that there would be a lot more of these mines in that area given the Germans submarine ports of Brest etc. But how did a mine get 2km down? Yes I know it could be silting...but hey a mile of silting on top???!

Just a morning pondering over my first cup of tea, and you know I am no good till I drink my second one.

OK, if I must

There have been several VEI 6 and VEI 7 that have been recorded either in detail or after a fashion, depending how long ago. Wikipedia lists these in reverse order so at least back as far as Laki on Iceland - of which there was a book written after the event (I will try and find the reference) - are fairly well documented.

ETA: The map in Wiki is quite good

Krakatoa was an ESTIMATED VEI6 and as you have explained the difference between a 6 and 7 is huuuuge!

At the end of the day they are all 'estimated' as it is pretty much impossible to actually measure each ton of ejecta!

...but Hellas is coming from the 'experience' if you will, perspective.

Oh I do understand and I am not denigrating the effects of a Santorini caldera style eruption on the human population, but it is a highly unlikely scenario and by the time it happens in say 45,000 years time there probably won't be any human population to be concerned about it.

It is, I guess, just that it was not one of the largest and I like to be reasonably accurate.

As to these 'explosive' EQ's in the channel....is it just me, but don't you think it's rather weird that we still have these 'mines' still going off, some 65 years later?

No even silting would not account for 2km in that short space of time I believe otherwise the Channel Tunnel would be obsolete. The English Channel is not very deep - average 63m according to Wiki. If 2km had silted in 65 or so years that is around 30m a year so bye bye Channel in about 2 years?

Earthquake location programs are notoriously bad at depths as you can see from the wide range of depths that we get from different providers. No one EVER gets the same depth. 2km sounds to me like a 'default' depth for a poorly constrained depth (it came up 0 and the program scratched it's head?)

Yes I believe so. There is also a small swarm going on around Van in Eastern Turkey, where the big one was recently. I created some Google Earth images of these last night but I have not had time to process it all yet.

Question for the Kiwis.
Did anyone hear about this quake? "120km West of Auckland Mag 5.1" I think it was, heard it on the radio at work on the 10:30am Radio NZ News yesterday, but when I got home and checked Geonet there is nothing anywhere near that location, and no 5's anywhere NZ.
Strange location, although there were a couple of 3's off the west coast upper NI recently which I posted here. One was at Aotea Knoll, but I can't find it on the ATS Search and its not on my 7 or 30 day maps either now, must have been revised.
New recording system playing up??

My system would have been up and running then - 11:30pm our time? If so I would have caught it in the deleted bin but there is nothing in that, except a 5.5 in Alaska on the 18th.

The following is my opinion as a member participating in this discussion.

reply to post by angelchemuel

Hello AngelChemuel,

just to add to what Puter's already said re mines/bombs going off 65 or 70 years later. It's actually not all that strange. Rather, it's the opposite, because a lot of the unexploded ordnance -- dropped on land or into water (whether on targets, jettisoned or within downed aircraft and sunken ships) -- is still very much "live" in respect of the high explosives used, but over time, the metal casings of these bombs have been steadily deteriorating. This can lead to the things becoming extremely unstable, so much so that even the tiniest sudden movement or bump can be enough to set them off. Or sometimes they don't even need that. They just corrode away to a point where they can explode.

A case in point is the SS Richard Montgomery, which sank in the Thames Estuary in 1944 with around 1400 tonnes of explosives on board:

An investigation by New Scientist magazine concluded in 2004, based partly on government documents released in 2004, that the cargo was still deadly, and could be detonated by a collision, an attack, or even shifting of the cargo in the tide. The bad condition of the bombs is such that they could explode spontaneously.

The wiki article about the above is here.

There is still WWI ordnance being dug up in fields in France that is live. Farmers often turn them up when ploughing and the army there does regular tours around the countryside to collect and destroy the ordnance with controlled detonations. Fortunately most WWI ordnance was relatively small, but the WWII stuff is often both more powerful (per kilo) and physically larger.

It is likely that over the next few decades there will be an increasing number of cases of old bombs going off. Sadly, it's just one of the legacies of our rotten, foolish wars.

And about that depth anomaly: again, I have to agree with Puterman on this. It could well have been an old bomb/mine that went off on the floor of the Channel, maybe only some tens of metres down. The water itself has an "enveloping" effect -- which was used to advantage in the famous "Dambusters" attacks, for example: the sheer mass of the water helps to deflect more of the explosive force in one direction, in this case back down into the sea bed. This would make it hard to get an accurate read on the "true" depth.

There is definitely something going in Iceland, at Tjörnes Fracture Zone. It looks like volcanic, but there is not known volcanoes in the area. Swarms are very frequent and has signs of harmonic tremor. I don't have any idea what is happening there, it has been going week already. After that strong earthquake on 30th of August at Jan Mayen, there has been lot activity on north side of Iceland. Strongest earthquake at Tjörnes Fracture Zone has been 4,5 magnitude. There has been 290 earthquakes during last 48 hours, some are very weak, but some strong ones too. Strongest activity was recorded on Thursday.

Na itwas definitely West of Auckland, thats why took note of it.
Probably a media mistake or Geonet mistake that has been deleted as soon as the media got hold of it.
The media is right onto any quakes now since Christchurch, Last night on the TV news, as a lead in to a story about the Silver Ferns Netball team visiting Christchurch for the first time since Sept 2010 they mentioned this quake

Public Id: 2012p713691
NZST: Friday, September 21 2012 at 1:35:03 pm
Intensity: strong
Depth: 12 km
Magnitude: 4.3
Location: 15 km east of Christchurch

www.geonet.org.nz...
also note the number of felt reports 875
and the history of the quake, the machine got it up to 4.6 at one point
biggest quake for a while there, although I noticed a pick up in numbers and magnitudes in Canterbury over the previous few days. This areas earthquake history is too recent to be able to predict a bigger quake, but this week has been interesting.
