Abstract: 

When Grimsvötn Volcano in Iceland erupted in May 2011, northern European airspace was closed for seven days and about 900 passenger flights were canceled. Scientists were charged with trying to read the volcano — to tell how high the ash plume would go and to figure out how long the violent eruption would last. Such features are hard to predict, but in a novel study, one research team has found a correlation between the height and composition of the Grimsvötn ash plume and ground deformation before and during the eruption.
