Aon: Event Analytics Platform Post Catastrophe Reports
Aon’s Event Analytics platform is aimed to assist insurers and reinsurers to make better, more informed decisions before, throughout and after an event.
The even platform is equipped with integrated hazard, exposure and loss data, accessible from a single, seamless interface.
Dan Hartung, recently promoted to global head of Event Response for Risk Capital, says: “Insurers are under pressure to make decisions with speed and precision, but fragmented data sources often slow down decision-making.
Aon’s Event Analytics platform is designed to support re/insurers through all phases of global catastrophes, helping them to quantify and respond to the effects of high-impact events.
It delivers actionable insights that enable insurers to triage losses, mobilise resources and communicate effectively with stakeholders – all in near real-time”
The platform integrates real-time loss estimates from Impact Forecasting’s Automated Event Response service, advanced mapping tools for visualising event footprints and customised reporting for key stakeholders.
A key feature allows users to recast historical events, such as Hurricanes Milton, Ian and Helene, to analyse their potential impact on today's portfolios.
Aon’s recent Climate and Catastrophe Insight report lists that the US’s third-deadliest Hurricane Helene was the US insurance industry’s costliest event, with US$75bn in economic losses, and 243 fatalities.
Constant complications for counties which suffered the most from flooding caused by Hurricane Helene are very low public and private flood insurance take-up rates, creating a large insurance gap.
The report lists that the number of all residential structures typically covered under the National Flood Insurance Program (NFIP) in western North Carolina were less than 2%, with the number decreasing even before Helene hit.
The Global Catastrophe report also lists that in the first half of 2025, economic losses reached at least US$162bn, due in part to the uptake in natural disasters that swept through the US.
In the first half of 2025, the report shows that the US was home to 90% of global insured losses, with the top 5 totalling close to US$60bn.
How does Aon’s new platform help?
This strategic insight provided by Events Analytics platform helps drive better decisions, improve claims efficiency, and enhance the customer experience during catastrophic events.
Aon’s Global Catastrophe Recap estimates global insured losses to exceed US$100bn in the first half of 2025.
The estimation is the highest the total has been since 2011, when it was reported to be US$140bn.
This underscores the urgent need for re/insurers to manage catastrophe costs effectively.
Natural disasters and insurance costs
In the US, natural disasters exceeded a cost of US$218 billion in 2024.
The average across the same period was listed in the Climate Catastrophe report as $109bn, seeing the US exceed over double the average.
High severe connective storm (SCS) activity has also been cited as a cause for costly insurance payouts in the first half of 2025.
Two severe weather outbreaks caused damage across several areas in the US, with insurance losses currently estimated at US$8bn each.
The events are among the highest in cost for SCS storms in US history.
SCS damage has also been listed as a growing concern for insurers in the Climate Catastrophe Report.
Asphalt shingle roof replacements have seen an increase due to severe weather, which places more financial strain on insurers.
Insurers are considering adjusting the cover offered to policyholders in the form of implementing different deductible structure for roofs compared to the rest of the home.
Alternative options include the exploration of co-pays for roof replacements and repairs in order to ease the financial burden.
