In-Depth Information
If a Katla eruption commenced prior to the ICP issuing a warning 55% of par-
ticipants stated that they would call 112 or the police (the most popular response) for
information while a further 28% would seek information from the radio, television, or
internet. Sixty-two percent of participants considered jökulhlaup as the most serious
hazard in their area if Katla were to erupt while tephra was deemed most serious by
26% (Table 2). We then allocated scores to the rankings (i.e. the most serious hazard
was allocated a score of 8; the second most serious was allocated a score of 7 and so
on). A nil score was allocated if no ranking was given. Each hazard was ranked at least
once (Figure 3) with jökulhlaup and tephra scoring the highest respectively.
