DESCRIPTION
In this slide deck, ICLR talks about the increasing challenges faced by various stakeholders -- most particularly insurers - in managing risks associated with severe weather and seismic events.Discussed is how severe weather losses are rising across Canada and around the world and what can be expected through the next decade in terms of disaster loss claims and prevention. The deck end with a discussion on ICLR's work and its efforts to help insurers and others mitigate the impact of severe weather and earthquake events.

Based on data from the Canadian Disaster Database, Public Safety Canada
Canadian catastrophes
Primary concern rests with flood and earthquake (the latter on the west coast and the Ottawa/Montreal corridor)
Many instances of flood, few of EQ Though when (not if) a major earthquake strikes
the west coast, damage will likely be severe 13 great earthquakes along this fault in the last
6,000 years Five richter 7+ events in the last 130 years in
southwest B.C. and northern Washington state Seattle earthquake, February 28, 2001, R 6.8 Will happen again, just a matter of when Are we ready?
EQ scenarios
Canadian catastrophes
Hurricanes seldom impact Canada
Usually just remnants when they do hit Biggest concern is on the east coast
Forest fire becoming a concern as developments
grow and interface with wildlands
Tornado risk also increasing due to growing
development
Misc. risks such as ice storm, blizzard, hail etc.

New normal
“The Institute for Catastrophic Loss
Reduction (ICLR) reports that large
insured losses from extreme weather
appear to be ‘the new normal’ for the
Canadian insurance industry, expecting
that large-loss years will no longer be
rarities.”
Canadian Underwriter (November 6, 2012)

Role of insurance
Pay disaster losses
Support research in climate extremes
Lobby for better disaster management
Promote better building practices
Provide incentives and disincentives
Through pricing
Through policy wordings/exclusions
Through refusal to bind coverage
But insurance is NOT mitigation, it is simply
passing on the bill to someone else

Three main areas of concentration
Housing
Municipal governments and cities
Small business
Hurricane Gustav
We found one house in Houma, LA with a roof failure
(city of 100,000 people). The cause of the damage was
missing toenails.
The roof flew off the left house and landed on the roof of
the right house, penetrating the sheathing.

The concept

Should work well for
structural tests
Problems with connections
are the major issue for
response to wind.
Roof-to-Wall Connections
Example of a toe-nail roof to wall connection in the house where the
nail has split the wood and offers very little hold down force.
Estimates of the hold down capacity of toe-nail connections on the test house
vary from 30lbf to 160lbf (based on past literature)
Every connection (roof sheathing and roof-to-wall toe-nails) in the house has
been recorded to aid in the interpretation of the experimental data and to aid
computational modeling.
These data will be used for the development of probabilistic failure (risk)
models

Caused approx. CAD 1 million in damage
One house severely damaged, focused on it
Observe damage and measure wind throw of debris to attempt
to determine wind speed
Use models and the wind tunnel at UWO
One of the most common problems found is improper attention

1” thick steel rods that anchor the floors together, including between the first floor to the foundation;
Steel braces securing the trusses to the framing, and braced gable ends to withstand high winds;
Special shingles designed to meet 200 km/h standards, installed using additional nails and cement;
Heavy roof sheathing designed to stay dry, fastened with ring-shank nails in a tight nailing pattern;
Water-resistant sealing around windows and doors;
Adhesive weather-resistant strips installed over every joint in the roof sheathing to protect against water intrusion; and
Special wind-resistant siding, fascia and soffits.
