Industry-first Global Storm Surge Zones

Tropical cyclones put many areas of the world at risk from strong winds, storm surges and heavy rainfall. Hurricane Katrina in the US or Cyclone Nargis in Myanmar showed that if such storms hit flat coastal areas, storm surges can be the main driver of damage. While the loss potential is huge, there has only been limited availability of risk information and no global overview up to now. With the launch of the industry’s first Global Storm Surge Zones, Swiss Re is closing the gap. Our storm surge hazard zones enable our clients to pinpoint their storm surge risk with a consistent, worldwide, probabilistic and highresolution risk look-up in Swiss Re’s CatNet tool. The zones show that almost 230 million people – roughly 3% of the world’s population – are exposed to storm surge risk.
