The second major earthquake in Canterbury in February 2011 was
more devastating than the first in September 2010. Although it was
of a slightly lesser magnitude, it was shallower and centred nearer
the Christchurch CBD. This resulted in loss of life and greater
damage than occurred during the September earthquake.
The incidence of two major related loss events in a short period
has raised complex insurance coverage issues beyond those arising
from each loss alone. This is particularly so for those
policyholders who suffered both losses in the same policy year.
APPLICATION OF DEDUCTIBLES AND AGGREGATE LIMITS
The application of deductibles and policy limits can be dictated
in the policy by whether the events are in a series and arise from
the same source or original cause. We have had to obtain expert
geotechnical advice from earthquake specialists in order to advise
underwriters on this issue.
