3. SARA
SARA is a three year project, funded by Swiss Re Foundation, focused on
the assessment of potential losses and impacts of earthquakes in South
America
Our goal: to obtain a transparent seismic risk model, produced by local
experts in a close communication with decision makers

15. Regional and integrated risk assessment

16. SARA
We are more than
observers.
We are working together
as a community;
for the community.
We are not only creating
a platform for assessing
risk, but creating a
network that will use it
for developing risk
management strategies.

17. SARA: the end of the story, December 2015?
SARA is part of the
solution for seismic risk
management
