Iceland volcano update - Eruption in Eyjafjallajökull
Wednesday 5, May 2010
Since Monday 3 May, increased earthquake activity beneath Eyjafjallajökull has been recorded. Precise locations of the earthquakes show that their source is at first very deep, at about 23 km depth, but then migrates upwards.
This strongly indicates that "new" magma is intruding into the magma conduit and pushing on the over-lying magma, causing a difference in pressure at the surface. It is therefore anticipated that the eruption will continue at full force in the next days.
Significant changes in horizontal movement at GPS stations around Eyjafjallajökull have been observed in the last 48 hours. Renewed northward displacement is seen at stations BAS2 and STE2, located just north of the ice cap. To the south, westward movement is apparent at THEY (see figure below), while station FIM2 - located further east - shows eastward movement.
The distribution of earthquake activity in the magma conduit could also indicate the location of the magma chamber that has fuelled the eruption since 14 April. It is considered to be at a depth of approx. 3-5 kilometers, in an area where no earthquakes are detected.

More and more travellers think that researching and planning a European city break is half the fun and they're not interested in pre-arranged trips or escorted tours. Self-guided tours offer a lot of advantages but require some guidance and good resources.
With the recent wild fires, disrupting flights and increasing air pollution, environmental quality is a growing factor in attracting tourists.
