  1. currently around 18c dry and sunny, however around 4pm had a dust devil or something as the wind really whipped

    up for around 5-10 minutes blowing washing off the line and blowing all sorts of dust and twigs up in in the air,

    then just dropped completely still again very eerie!

    Would be interested if anyone else saw this around the bristol/bath area or whether it was very localised?

  2. Intresting info on Wiki about Eyjafjallajökull and how historically it has triggered off the other Volcano Katla.

    that might cause some effect!

    Eyjafjallajökull and Katla

    Over the past 1,100 years, Eyjafjallajökull has erupted four times: in 920, 1612, between 1821–1823, and in 2010. Each of the first three of these incidents directly preceded a major eruption in the nearby subglacial volcano, Katla.

    There is so far no evidence that Katla will erupt because of its vicinity to the current eruption in Fimmvörðuháls mountain pass. Katla, which is a much more active volcano, known for its powerful subglacial eruptions and its large magma chamber, much larger than that of the Eyjafjallajökull volcano system, has still not shown any unusual activity, like expansion of the crust or seismic activity.

    However, one can not rule out that possibility, since history has shown that Eyjafjallajökull can be a precursor to additional Katla activity. Some geophysicists in Iceland support the notion that the recent volcanic eruption at Eyjafjallajökull may trigger a second eruption at Katla, which would cause a major flooding event due to melting of glacial ice.
