  1. Some twitter footage now about, it's not a small eruption! Hopefully the evacuation of the northern end of the island is near complete.
  2. Big question is "complex" life? As the difference between simple single celled and complex life that has cell differentiation is huge. Alien single celled forms of life must be a certainty, at this level it is just a case of the right conditions and suitable time periods being available for the inevitable biochemistry to occur. Complex multicellular life however is a very different kettle of fish. It is postulated that simple, single celled forms of life emerged multiple times on the Earth at the earliest opportunity, but multicellular organisms just a few times as this requires a
  3. Nice idea BrickFielder. 👍 The 1200 eruption may have been a VEI4, a repetition of which would be big enough to cause major problems for San Salvador. Vesuvius 79AD was VEI5 - ten times as big, but the Soufrière Hills volcano on Montserrat destroyed the capital of the island, the town of Plymouth, with a VEI3 back in 1995, so it is clear that the El Boquerón system could cause significant problems. I use those two examples as Pompeii is about the same distance from the summit of Mt Vesuvius as the centre of San Salvador is from it's name sake (6 miles) and the town of Plymouth was a
  4. From reports it sounds like a graben has possibly formed so i would expect that we will initially see the venting of steam etc that we saw back in 2014. question is, will we then get the fountains and flows that followed? From the sounds of it, activity on the peninsula can, once it starts, be a long lived on/off affair over a number of centuries. Buckle up!
  5. And a press briefing link. Volcano alert press conference: live updates WWW.RUV.IS The civil protection agency gave a press briefing at 16.00. It was broadcast live on most radio and TV channels and the highlights in English are below.
  6. Looks like an eruption may be about to start. Aviation ash warning has been bumped to orange, pulse tremor is now ongoing and i understand there is evacuation of properties in the vicinity of Keilir.
  7. Just seen this in the Guradian - report on a nature geosciences communication paper from today. Atlantic Ocean circulation at weakest in a millennium, say scientists | Environment | The Guardian WWW.THEGUARDIAN.COM Decline in system underpinning Gulf Stream could lead to more extreme weather in Europe and higher sea levels on US east coast Link to communication Current Atlantic Meridional Overturning Circulation weakest in last millennium | Nature Geoscience WWW.NATURE.COM The Atlantic Meridional
  8. Big earthquakes on the Reykjanes peninsula of Iceland where there has been significant inflation over the past year. Something about to pop?

  9. Of all the rocky/solid bodies in the solar system, the surface of Venus is undoubtedly the most hostile to a human landing. Even the robust unmanned probes that have landed there succumb to conditions within hours. The Jovian moon Io is probably second in terms of hostile environment, but that's more to do with the strong radiation field of Jupiter. The mid/upper layers of Venus however might be tolerable for simple extromophile organisms.
  10. Over winter the ECM has regularly thrown out solutions which depict high uppers getting dragged up to the uk from iberia/East Atlantic. None have ended up being anywhere close to what actually happens with any warmth normally being mixed out before it gets past the Pyrenees. Interesting to see how this latest one goes?
  11. Think this may depend on context? When it is invoked to say a breakdown will not happen despite all the models saying breakdown, then yes, you have a fair point. There is however to my mind, a regular window in the modelling of an Easterly that actually lands, where the models all tend to being over progressive in regards to it's duration. This current one being no exception, when it went from being the mother of all easterlies to the models then saying a Sunday to Wednesday affair only. If someone says the block is being underestimated during this commonly observed model swing the
  12. The second one has // in its legend so i assume it's the parallel run.
  13. SE feed, so as @nick sussex alluded to, looking at the values over France where the airmass will be coming from, then maybe?
  14. Excellent, an Ice Spike! I remember a good few years back a long running discussion in the letters section of new scientist about the mechanics of how these form. Ice spike - Wikipedia EN.WIKIPEDIA.ORG
