This release includes new user interface features, updates to Verisk models, and enhancements to the application programming interfaces (APIs). To learn more about the extent of updates for this release, refer to the Touchstone and Touchstone Re 2025 Release Documentation page on the Client Portal. To reference the previous verions of AIREvents and AIREventsHistorical databases, see the AIREvents Repository on the Client Portal.

Notable Verisk models that impact the AIREvents and AIRHistorical databases are:

Verisk Severe Thunderstorm Model for the United States

As part of the model updates, we updated catalogs and event sets.

Stochastic catalog(s)

• We redefined baseline catalogs and expanded events:

• The baseline catalog includes significant loss events defined using both country-wide and state-specific loss criteria. The baseline catalog is the smaller of the two catalogs.
• The expanded events catalog includes all events from the baseline catalog and additional events that do not exceed the baseline loss thresholds but do meet the meteorological criteria defined for this model. This catalog is the larger of the two catalogs.

• We added the following new catalogs and regenerated events:

Touchstone	Touchstone Re
10,000-year Baseline 10,000-year Expanded Events 50,000-year Baseline 50,000-year Expanded Events 100,000-year Baseline 100,000-year Expanded Events	10,000-year Baseline All event IDs are new.

Verisk Bushfire Model for Australia

We updated the following catalogs and event sets:

• Stochastic catalog(s): Updated 10,000-year catalog.

This release includes new user interface features, updates to Verisk Models, and enhancements to the application programming interfaces (APIs). To learn more about the extent of updates for this release, refer to the Touchstone and Touchstone Re 2024 Release Documentation page on the Client Portal. 

Notable Verisk Models and updates to software that impacts the AIREvents and AIRHistorical databases are:

• We added  a new classification as induced seismicity events to categorize a subset of events. The induced seismicity events are not caused by natural tectonic plate movement but rather from human activities such as hydraulic fracturing (“fracking”), building water dams, and shallow oil field operations. These updated source type classifications are reflected in the: AIREvents.TblModel50.database, loss dashboard screen, Event Loss Summary Table, and the Event Distribution CSV export for this model. There is no impact on losses from these labeling updates.
• We updated the Industry loss files for both the stochastic (10K) and historical catalogs for the Verisk Inland Flood Model. An updated views of industry insurable loss files for residential content line of business is available for this model. 

Touchstone and Touchstone Re 2023 include new user interface features, Verisk Model updates, and enhancements to the application programming interface (API). To learn more about the extent of updates for this release, refer to the Touchstone and Touchstone Re 2023 Release Documentation page on the Client Portal. 

Important Verisk Model and software updates that impacts the AIREvents and AIRHistorical databases are:

• We added support for two new models in the AIR Events and Historical databases: Verisk Earthquake Middle East Model (M50) and Verisk Inland Flood Model for Italy (M96).
• We removed event sets for the previous model versions of the older models to keep model file sizes manageable. Going forward, we will periodically clean up the model versions of the older models.  
• We updated the catalog for the existing TblModel85 to reflect the updated Verisk Agriculture Model for China.
• The historical catalog for Verisk Hurricane Model for the United States has been updated to include three additional historical events: Hurricane Sally (2020), Hurricane Zeta (2020), and Hurricane Laura (2020) and one updated event, Hurricane Betsy (1965).
• The Verisk Pandemic Model has an updated Filovirus catalog to reflect the increased availability and uptake of vaccines, especially for Ebola, and a new vector-borne diseases catalog.
