Zusammenfassung |
Katla volcano, located beneath the Mýrdalsjökull ice cap in southern
Iceland, is capable of producing catastrophic jökulhlaup. The Icelandic
Civil Protection (ICP), in conjunction with scientists, local police and
emergency managers, developed mitigation strategies for possible
jökulhlaup produced during future Katla eruptions. These strategies were
tested during a full-scale evacuation exercise in March 2006. A positive
public response during a volcanic crisis not only depends upon the public's
knowledge of the evacuation plan but also their knowledge and perception of
the possible hazards. To improve the effectiveness of residents' compliance
with warning and evacuation messages it is important that emergency
management officials understand how the public interpret their situation in
relation to volcanic hazards and their potential response during a crisis
and apply this information to the ongoing development of risk mitigation
strategies. We adopted a mixed methods approach in order to gain a broad
understanding of residents' knowledge and perception of the Katla volcano in
general, jökulhlaup hazards specifically and the regional emergency
evacuation plan. This entailed field observations during the major
evacuation exercise, interviews with key emergency management officials and
questionnaire survey interviews with local residents. Our survey shows that
despite living within the hazard zone, many residents do not perceive that
their homes could be affected by a jökulhlaup, and many participants who
perceive that their homes are safe, stated that they would not evacuate if
an evacuation warning was issued. Alarmingly, most participants did not
receive an evacuation message during the exercise. However, the majority of
participants who took part in the exercise were positive about its
implementation. This assessment of resident knowledge and perception of
volcanic hazards and the evacuation plan is the first of its kind in this
region. Our data can be used as a baseline by the ICP for more detailed
studies in Iceland's volcanic regions. |
