[Rockhounds] Earthquakes can 'spark eruptions'

[Axel Emmermann]

Hi Kreigh,

Very intriguing presumption! 
I wonder if (and that 's one of my more simplistic theories for discussion's
sake ;-)) magma would behave like a true fluid when pressure wave pass
through it.
Would it, just like CO2-saturated water, immediately start to release its
dissolved gasses? (water, fluorine, CO2....)
This link http://www.bbc.co.uk/science/horizon/2001/killerlakes.shtml
somewhat translates the idea to volcanic lakes.

I'm still working on the X-ray generating scotch tape. I'll use another
approach but it gets pretty cosmological too ;-))))))))))

Cheers
Axel
