  1. They don't protect you they protect the rest of us. no one has said wear a mask to avoid getting the virus but they have said wear a mask in case you have it to stop spreading it. Simple really if you have a mask on and cough the virus can't travel as far as it would if you didn't have a mask on. Anyway, having just been back on the motorways for the first time in months, what tick me off are people sat in the middle lane for no reason.
  2. reading this thread. Personally, i think David Icke talks a lot of nonsense and should have stuck to Grandstand. however, he has picked up on some interesting points. I do not subscribe to conspiracy theories as such but I have to confess to thinking that there is something very fishy going on at the moment with the world economy especially. It seems timely that the economy should be shut down almost entirely at a time when it was already badly broken. Not many know that the Federal reserve has been propping up the US economy since last September to the tune of $75-$120 Billion Dollars a d
  3. I've been fascinated by the markets for a while and you are correct Quicksilver things are very interesting at the moment. I think some sort of major downward correction is likely later this year or possibly earlier next year. The recovery since March is a result of all the economic stimulus rather than any improvement in the global economy and other bizarre activity is the likes of Hertz an essentially bust company has seen its stock price go up! Metal and commodity prices are also worth watching at the moment, Gold and Silver in particular are going up and up.
  4. Quite right Lorenzo. That photo is pretty impressive, it must be one hell of a feather under that ice to result in a surface expression of that magnitude! Picking up on Rustynailers point, there will be some melt although where that's going at the moment is a bit of a mystery unless it isn't erupting yet and that depression is as the official web sites are suggesting is just the result of rifting. If it is erupting under there it will be melting but could be getting trapped, a bit like a dam, this will give way at some point with a huge outburst flood. Grimsvotn did this in 1994 if I r
  5. No it will take a while unless it gets very explosive, the ice and meltwater will cool the surface of the lava which sort of insulates it, that's why Grimsvotn and Bardabunga are almost completely entombed in ice, they've erupted most of the time sub glacially. A good indicator as to what these volcanos probably look like is Herdubreid, this was similar to Grimsvotn, etc in that it was formed beneath an ice cap. This graben development is getting very interesting, things could get considerably more active, this looks to me like it has the potential to become a rift fissure eruption, whi
  6. I think Rustynailer probably summed it up, it is most likely due to lower resistance either the fissures are more open now or, as the dramatic photos suggest the surface cracking is leading to a reduction in pressure. If it was a reduction in the volume of magma I think we'd see a much bigger drop in the number of earthquakes, whereas the frequency doesn't seem to have reduced that much just the magnitude. It can't be long now before it erupts, just have to see if it will interact with Askja or not and if the central volcano will play a part or not. Very impressive photos, sort of stuff nig
  7. I was wondering that myself but I can't tell if it is more water or if its just the sunlight reflecting off the water. M
  8. Blimey, take your eyes off it overnight and it goes mad! Some big events all over the area this morning and now well intersecting Askja. Yesterday it looked to me like the dyke may track to the east of Askja, clearly its just gone straight for it. Things could start to get very interesting looking at the discussions presented in the links posted throughout this discussion. Especially if it reactivates the magma beneath Askja.
  9. I think the 4.6 in the dyke and the 3.3 at 30km could be another pulse of magma coming in from depth. That idea will be better supported if there are any more of that magnitude anywhere in the dyke and any further ones at depth. If I'm right it may also be indicating the magma is going straight for the dyke and bypassing Bardabunga. The link John Pike posted has some good information, interesting to see the dyke is now 10km north of the ice cap, although the depth of the activity is not pointing to eruption yet if it does happen it seems more than likely it will be at least in part in the o
  10. Yes quite right Snow, it would be interesting to see if there's any settlement data or gravity data from Bardabunga to see if it backs that up, the link below shows some GPS data http://volcanocafe.wordpress.com/2014/08/24/bardarbunga-nature-of-the-beast/ But its not from Bardabunga specifically and a few days old now. Activity does seem to be tailing off but just spotted that there was a 3.3 at 30km depth about 12:30, could this be a fresh pulse of magma?? M
  11. Not quite, it contains a number of volcanic systems which in most instances work as separate entities, but have the potential to link during more extensive eruptive cycles as seems to be the indication with Bardabunga at the moment. However, there are a number of peaks that have now moved well away from the rifting zone and are unlikely to erupt again, thus we would not have the whole of Iceland erupting as a single giant eruption that would lead to a tsunami. The only conceivable way in which a tsunami might be generated from an eruption is if we had a cataclysmic eruption from Surtsey or t
  12. Allseasons, even if this volcano has a cataclysmic eruption as Krakatoa did it will not generate tsunamis. It is too far from the coast whereas Krakatoa was a very small island and surrounded by enormous volumes of sea water which was able to contact the magma immediately after the eruption. There is obviously plenty of water around Bardabunga in ice form, however this will potentially cause a much more explosive eruption and generate lahars and its distance from the coast means it cannot interact with the sea in a manner which would give rise to tsunamis. m
  13. It seems to me that it could mean both just to give an awkward answer. Its a while since I studied volcanology, groundwater is my specialist field in geology but having read the excellent article Allseasons-si gave the link to its coming back. At the moment it seems that the M2.0s are indicative of magma moving, it is the direction of movement that is most interesting at present. It seems the thought is that the link could be made with the Askia system and in essence the longer the M2.0s go on without any eruption the larger the eruption might be. The M4 - 5 tremors are also interesting as
  14. I fired that reply off very quickly and didn't quite say what I was trying to say! it is quite probably monsoon for India with apparently very permeable aquifers looking at the response. I was thinking more in terms of the Australian changes, I didn't think there was a huge amount of abstraction in the outback. Interestingly, and in response to Mike's point, it isn't just over abstraction that is having a negative effect on the UK's aquifers, theres a growing problem of reduced infiltration rates as a result of urbanisation, tarmac and hardstanding coupled with efficient drainage systems is
  15. Brilliant stuff this Knocker, as a Hydrogeologist I find the GRACE imagery very exciting and the variations in India especially very interesting. It would be interesting to understand how much is climatic induced variation and how much is anthropogenic. M
