Iceland Volcano Plumbing
A student (thank you Robyn) pointed me in the direction of this excellent article all about the Eyjafjallajokull volcano and its magma plumbing. It’s a really interesting read particulary how they’re using radimoetric readings from the TerraSAR-X German satellite to look at how the land deformed leading up to the eruption. This is extremely important in the race to make the science of predicting volcanic eruptions a more accurate one.
Essentially the eruption was a phreatic one where water mixed with magma to produce the ash materail that caused havoc around Europe for airline travellers. Check out some typically good BBC graphics here on the eruption plume. Check out the brillinat pictures on the eruption on the Boston Globe website here.
