capability, data interpretation and communication have ad-
vanced with these events. In addition, before the unrest, a variety of
new instruments were installed around the Vatnajökull ice cap by
collaborators in the research project Futurevolc.
During the period of unrest, the Department of Civil Protection and
Emergency Management met regularly with scientists to discuss the

It is noticed that the matrix is in reality three-dimensional
(source, type, nature). Thus, the categories type and nature
are not mutually exclusive, and it may be argued that the ma-
