Hi,

I'm just finishing a book called "No Apparent Danger".  It's about the 2
eruption disasters in Colombia in the 80's and 90's.  There's graphic detail of
both eruptions.  In the second one an entire volcanologist conference was on the
volcano when it erupted with tragic consequences.  There is also a description
of the history of seismology in Colombia, the USGS attempts to help and
descriptions of seismic signatures of volcanoes....

Great read, here's a link to the book on Amazon:
