Fathom joins forces with cat modeling leaders in new Insurance ERM report on natural catastrophes
Explore the evolving landscape of catastrophe modeling and risk management in the face of increasing flood, fire and storm events.
This special report from Insurance ERM, Fathom, Bellwether and Reask explores the latest advancements in catastrophe modeling. Focusing on flood, hurricane, and wildfire risks, ‘Natural Catastrophes: Flood, Fire & Storm’ unpicks how new technologies and open standards in catastrophe modeling are revolutionizing the way that we understand and manage natural catastrophe risks.
This report provides insights into the most significant shifts in risk and the innovative modeling approaches being developed, featuring perspectives from leading cat modellers and exposure managers.
Key findings from the report
Technology is transforming cat modeling
Making it easier access to high-power computing, satellite imagery, and advancements like AI and machine learning, which are driving significant improvements in model accuracy and accessibility.
Primary loss driving perils are changing
Events like severe convective storms, floods, and wildfires are causing more losses than traditional primary perils such as tropical cyclones and earthquakes.
Open modeling is democratizing risk management
The emergence of open-source frameworks is enabling greater accessibility, innovation, and transparency in cat modeling.
Climate change is reshaping the landscape of risk
Rising temperatures and sea levels are increasing the frequency and severity of many natural disasters, requiring a shift in how models are developed and applied. New catastrophe models are helping risk managers to adapt.
Background to the report
This special report has been compiled in collaboration with leading experts in catastrophe modeling. It features insights from cat modellers and exposure managers. ‘Natural Catastrophes: Flood, Fire & Storm – Special Report 2025’ also includes interviews with sponsors Fathom, Reask and Bellwether, who are working on the forefront of catastrophe modeling solutions.
