The existence of possible deep connections between nearby volcanoes has
so far only been formulated on the basis of correlation in their
eruptive activities or geochemical arguments. The use of geodetic data
to monitor the deep dynamics of magmatic systems and the possible
interference between them has remained limited due to the lack of
techniques to follow transient processes. Here, for the first time, we
use sequential data assimilation technique (Ensemble Kalman Filter) on
ground displacement data to evaluate a possible interplay between the
activities of Grímsvötn and Bárðarbunga volcanoes in Iceland. For details of this story, click this link.
